Repair Summary
The following article gives detailed instructions on replacing the front axle shaft on a BMW E60 5 series xDrive (all wheel drive) car. Even though we have used a 2006 BMW 530xi to perform this installation, this article can be applied to any E60/E61 5 series xDrive vehicle with minor modifications.

A BMW E60 front axle shaft repair may be needed if you are experiencing shaking in the front end of your xDrive vehicle during acceleration and braking.

During a recent road trip in our BMW Repair Guide Guide 2006 530xi touring wagon, we collided with one of I-95’s infamous exit ramp pot holes (thank you SCDOT). This deep void in the asphalt sent a bone jarring jolt through the right front side of the vehicle, through the steering wheel, and through our teeth. Immediately after the collision we noticed a “side to side” shake in the front end of the car when applying the accelerator. It was a strange shimmy; it sometimes disappeared at high speeds (over 80 mph) as well as when we let our foot off of the accelerator pedal. The shake also mysteriously vanished when the car sat in the hotel parking lot for the night…only to quickly reappear after driving for a couple of minutes.

Upon returning to our shop, we raised the vehicle and inspected the front end. We quickly found our our first clue. When we grasped the right front axle shaft and put pressure on it, it moved back and forth with a clicking sound. The front axle shafts on an xDrive BMW operate exactly like the rear ones…they transfer power from the front differential to the wheels. The front axle shafts on a BMW should not have any play in them…much less make a clicking sound when you pull on them with your hands. When heavy torque is applied to a damaged front axle shaft, it will cause the front end to vibrate uncontrollably.

To further verify this may be our issue, we removed the fuse that supplies power to the transmission’s transfer case. The transfer case in your BMW xDrive is an electronically actuated set of gears that controls how much power is sent to the front and rear wheels. Removing the fuse that controls the xDrive transfer case shuts down any power being sent to the front differential, and effectively turns the vehicle into a rear wheel drive automobile. When we removed the transfer case fuse in our 530xi, it drove perfectly; there was no more shaking in the front end.

Diagnosing a BMW E60 front axle shaft failure
If the front end of your BMW xDrive vehicle is shaking during acceleration, and then the shake dissipates when you release the gas pedal, you may have a damaged front axle shaft. As we discussed above the only way to determine this is to get under the car, grasp the axle shaft with your hands, and give it a good shake. There should be absolutely no play in the shafts; if either one of them moves back and forth (usually with a clicking sound), then it is possible it is damaged.

The next step in verifying a BMW front axle shaft failure is to temporarily shut off power to the vehicle’s front wheels. This is done by simply removing the fuse that supplies power to the transmission’s transfer case. In a BMW E60/61 5 series car, this fuse is easily accessed in the glove box fuse block. Start by opening the glove box and removing the fuse block cover by turning the two release clips. The 30 amp fuse that controls the transfer case is located in position #13 in all vehicles produced from 2005-2010. In pre-2005 cars, the fuse may be found in a different position – consult the fuse diagram included with your car for more details . Use a pair of needle nose pliers to pull the fuse out of the block.

Remove the 30 amp fuse that controls the transfer case

With the transfer case fuse removed, start the car. You should see the following warnings on the iDrive and instrument cluster; this is a good thing…this means you removed the correct fuse.

You should receive an error message on your iDrive when the fuse is removed You should receive an error message on the instrument cluster when the fuse is removed

Take the car for a drive. If the front end shake has disappeared, then you most likely have a front axle shaft failure. If the shake remains, then you will need to continue with your diagnoses to find the culprit.

Tools needed to perform a BMW E60 front axle shaft replacement
There seems to be quite a bit of confusion about which specialty tools are needed to perform a BMW E60 front axle shaft replacement. The following is a list of what you must have, and what you can get by without.

1. 32mm and (or) 36mm 12 point shallow socket (required) – You must have a 36mm 12 point socket to remove an original BMW axle nut. Avoid purchasing deep sockets when removing and installing axle nuts with a breaker bar or torque wrench; deep sockets can slip off of the axle nut under heavy torque loads and literally break an arm (or neck). If you are using a high torque impact wrench, then deep sockets are fine. Be aware that many aftermarket axle shafts are shipped with a 32mm 12 point axle nut. Determine which size axle nut sockets you need before starting the repair…they are not always easy to find on short notice. You can order both sizes from our Tools and Supplies list below.

2. Hub puller (75mm opening) (required) – There are a lot of repair articles floating around online claiming you can “hammer” the axle shaft out of the hub to remove it. This is an incorrect way of removing the axle from the hub and can actually damage your vehicle…you must use a hub puller. Use caution when ordering a hub puller – there are a lot of inexpensive ones online that WILL NOT WORK on a BMW E60 5 series. You must have the larger 75mm hub puller to clear the hub flange so the drive axle can be pressed out. We used the large hub 4305 puller from CTA tools to do this repair and it worked great. You can order one by clicking here or from our Tools and Supplies list below.

3. Large torque wrench (300 ft-lb) (required) – The axle nut on your new axle shaft will need to be torqued to 310 ft-lb…this is a high torque that most wrenches don’t go to. The issue in purchasing a torque wrench for this job is once you exceed 300 ft-lb, the price for the tool goes up exponentially. Unless you are comfortable paying $150 or more for a 600 ft-lb wrench, you can get by with a 300 ft-lb wrench for less than half the price. 

4. Inner CV joint puller (slide hammer) (optional) – There are claims that a joint puller or slide hammer is required to remove the drive axle from the differential. These claims are not true…you can easily remove the drive axle with a large flat blade screwdriver or small prybar. If you happen to have a slide hammer sitting around the garage with an adapter that will work on a BMW E60…then go ahead and use it. If not, save yourself some money and just use a flat blade screwdriver like we do below.

A quick note on new axle nuts
All new axle nuts are shipped without locking tabs. Why? Because it would be near impossible to torque the nut properly and have pre-cut locking tabs line up with the slots in the axle shaft. The locking tabs are created with a hammer and a chisel by the mechanic after the axle nut is torqued on the axle. For more information on this, please see Section 7 -Step 9 below.

Replacing the front axle shaft seal
Although not required, the BMW Repair Guide strongly recommends replacing the front axle shaft seal when performing this repair. The front axle shaft seals do leak over time, so it makes sense to replace this inexpensive part while the axle is being replaced. You DO NOT need any special tools to reinstall a BMW E60 front axle shaft seal; in fact you can easily fabricate a tool for about $4 out of a 2″ PVC coupling and plug from your local home improvement store. We give you detailed instructions on replacing the front axle shaft seal in Section 5 below.

Section 1 – Removing the axle shaft nut
Removing the axle shaft nut can often be a struggle since they are often heavily corroded and are under a high amount of torque. Further complicating the situation are the locking tabs found on factory axle nuts are difficult to release and usually need to be broken or cut off.

  1. Keep the wheels on the ground…do not raise the vehicle until the axle nut is removed. The nut is almost impossible to get loose without the full weight of the vehicle on the front wheels.
  2. Use a metal pick or small screwdriver to remove the cap from the center of the wheel exposing the hub nut.bmw e60 front axle shaft - Use a metal pick or small screwdriver to lift the edge of the center wheel cap. bmw e60 front axle shaft - Remove the center cap from the wheel. Removing the center wheel cap exposes the axle nut.
  3. The axle nut has two locking tabs that fit into slots in the drive axle. The locking tabs must be straightened out or broken off before the axle nut can be removed. Use a hammer and a punch (or chisel) to try and straighten them out. You may have better luck trying to break them off altogether. Sometimes neither of these techniques work – we had to use a Dremel tool with a steel cutting disk to get ours completely cleared out.bmw e60 front axle shaft - Use a chisel or steel punch to try and straighten or break off the locking clips on the axle nut.bmw e60 front axle shaft - If you can't break off the locking clips, use a Dremel tool to cut them off. Cutting the axle nut locking clips off with a Dremel too.bmw e60 front axle shaft - Axle nut with locking clips removed.
  4. Liberally spray the axle nut with penetrating oil like Blaster PB and allow to soak for about 15 minutes. Most axle nuts are very corroded and need to be treated prior to removing them. Excessively corroded nuts should be treated several times before attempting to remove them.bmw e60 front axle shaft - Blaster PB penetrating lubricant. bmw e60 front axle shaft - Liberally apply a penetrating lubricant to the axle nut and allow to soak form about 15 minutes.
  5. Using a 36mm 12 point shallow socket and a breaker bar (or high torque impact wrench), remove the axle nut from the wheel. The axle nut is torqued extremely tight. We had to stand on the end of the breaker bar to initially loosen it. If the nut refuses to break free, continue to soak it in penetrating oil and retrying. Make sure you have all of the locking tab raised or removed from the nut…even a small piece can bind it up making the nut impossible to remove.bmw e60 front axle shaft - Use a 36mm 12 point socket to remove the axle nut. The axle nut is torqued very tight...stand on the end of a breaker bar to loosen it.
  6. Jack up the vehicle and support on jack stands. You will have to use jack stands for this repair since the front wheel(s) will need to be removed to replace the drive axle.
  7. Using a 17mm socket wrench, remove the five lug nuts. Remove the wheel from the car.
  8. Remove the front and rear belly pans using a phillips screwdriver and an 8mm nut driver.bmw e60 front axle shaft - Remove the front belly pan with a phillips screwdriver. bmw e60 front axle shaft - Remove the rear belly pan with an 8mm nut driver.
  9. Use a 16mm socket wrench to remove the six M10 bolts securing the skid plate to the frame of the car. Use an 8mm socket wrench to remove the mounting bolt from the rear of the skid plate. Remove the plate from the bottom of the car.bmw e60 front axle shaft - Remove the six bolts securing the skid plate to the bottom of the vehicle. bmw e60 front axle shaft - Remove the rear 8mm bolt in skid plate

 

Section 2 – Preparing for the BMW E60 front axle shaft removal
In order to remove the BMW E60 front drive axle, the steering knuckle must be rotated backwards 90 degrees inside the fender well (see Section 3 – Step 8 below for photos explaining this). There is unfortunately not enough clearance to remove the axle any other way. The following components must be disconnected from the steering knuckle in order to properly rotate it: the upper control arm (tension strut), lower control arm, steering tie rod and sway bar link. Contrary to other repair articles, you do not have to remove the brake caliper or any brake components to remove the front drive axle on a BMW E60 vehicle.

  1. Using a 16mm boxed or open end wrench and a T40 torx bit, remove the sway bar link from the sway bar. The T40 torx bit is necessary to counterhold the anchor nut. DO NOT remove the sway bar link from the front strut…this is not necessary. Just let the link swing freely out of the way.bmw e60 front axle shaft - Remove the sway bar link.
  2. Using a 24mm socket and a breaker bar, loosen the nut anchoring the tie rod to the steering knuckle. Use a T40 torx bit to counter hold the tie rod while removing the nut with a boxed end wrench. If you don’t have a 24mm wrench, an adjustable wrench works great too.bmw e60 front axle shaft - remove the tie rod ball joint nut.
  3. Give the top of the tie rod bolt a couple of firm strikes with a hammer until it pops out of the steering knuckle. If it is being particularly obstinate, soak it with some penetrating lubricant first like Blaster PB.bmw e60 front axle shaft - Use a hammer to strike the tie rod ball joint out of the steering knuckle
  4. Use a 22mm socket and breaker bar to loosen the upper control arm (tension strut) ball joint nut. Use a T40 torx bit and a 22mm open end wrench to finish removing the nut. If you are working on the right control arm, remove the headlight vertical aim control sensor with a 10mm socket wrench and open end wrench.bmw e60 front axle shaft - Remove the upper control arm (tension strut) ball joint nut. bmw e60 front axle shaft - If working on the right wheel, remove the headlight vertical aim control sensor.
  5. Using an 18mm socket and breaker bar, slightly loosen the upper control arm bushing bolt so control arm can be swung down out of the way. Pull the control arm off of the ball joint. If it is being obstinate, gently strike it with a rubber mallet until it pops off. bmw e60 front axle shaft - Loosen the upper control arm bushing bolt Remove the upper control arm from the ball joint. bmw e60 front axle shaft - Swing the upper control arm down and out of the way.
  6. Next, use a 22mm socket wrench to remove the ball joint nut off of the lower control arm. Use an 18mm socket and breaker bar to slightly loosen the lower control arm bushing bolt. bmw e60 front axle shaft - Remove the ball joint nut off of the lower control arm. bmw e60 front axle shaft - Loosen the lower control arm bushing bolt.
  7. Use a ball peen hammer to strike the lower control arm ball joint out of the steering knuckle. If it is giving you a hard time, soak it in Blaster PB and let it soak for a few minutes. Rotate the control arm down and out of the way.Use a hammer to knock the lower control arm ball joint out of the steering knuckle. bmw e60 front axle shaft - Rotate the lower control arm down and out of the way.
  8. Use an 8mm socket wrench to remove the side splash guard from the inside of the fender well.bmw e60 front axle shaft - Remove the splash guard screws with an 8mm nut driver bmw e60 front axle shaft - Remove the splash guard from the vehicle.
  9. You can now easily rotate the steering knuckle backwards 90 degrees to allow removal of the front axle shaft. You DO NOT have to remove the brake caliper or any brake components to complete this repair.

Section 3 – Removing the BMW E60 front axle shaft from the steering knuckle
Removing the drive axle from the steering knuckle requires the use of a 75mm hub puller. DO NOT try and remove the drive axle from the steering knuckle without the use of a hub puller. Trying to hammer the axle out with a steel punch or other method of impact can damage the vehicle and is strongly discouraged. If you do not have the correct hub puller, you can order one from our parts list above.

  1. Using a T30 torx bit, remove the wheel speed sensor from the steering knuckle. Use a flat blade screwdriver to pry it out of the knuckle if it is stuck.bmw e60 front axle shaft - Use a T30 torx bit to remove the speed sensor from the steering knuckle bmw e60 front axle shaft - Use a flat blade screwdriver to pry the speed sensor from the steering knuckle
  2. You will need to use a 75mm hub puller to remove the drive axle from the steering knuckle. Before starting, apply a thin layer of grease to the threads of the hub puller. This will help prevent the threads from stripping and will prolong the life of the tool. A large (75mm) hub puller. Smaller hub pullers will not work on BMW E60 5 series cars.bmw e60 front axle shaft - Apply some grease to the threads of the hub puller prior to using.
  3. Have an assistant sit in the car and apply the brakes. The brakes must be applied to keep the wheel hub from spinning in the following steps.
  4. Attach the puller to the wheel hub with three lug nuts. Use a 17mm socket wrench to firmly tighten them.bmw e60 front axle shaft - Attach the hub puller with three lug nuts.
  5. Using a socket wrench, slowly tighten the threaded rod on the puller. The rod should line up with the center of the drive axle. Continue to tighten the threaded rod until the axle pushes out of the hub. If the axle is stuck and won’t push out, proceed to the next step.bmw e60 front axle shaft - Tighten the hub puller and slowly push the drive axle out of the hub.
  6. If the drive axle is stuck and won’t push out, spray it liberally with Blaster PB and allow to soak for a few minutes. Tighten the hub puller as much as you can so there is adequate pressure being put on the drive axle. With pressure being applied, strike the axle behind the steering knuckle several times with a hammer until it releases from the hub (see image below). It took us six good blows with the hammer until the axle released from the hub. Don’t worry about tearing the boot…your replacement axle has a new boot already installed.If the drive axle is stuck, liberally soak it with a penetrating lubricant like Blaster PB.bmw e60 front axle shaft - Strike the axle several times with a hammer to get it to release from the hub. bmw e60 front axle shaft - Strike the axle right behind the steering knuckle to get it to release.
  7. Continue to tighten the threaded rod until it is all the way in. This will completely push the drive axle out of the hub. bmw e60 front axle shaft - Tighten the threaded rod all the way until it pushes the axle out of the back of the steering knuckle.
  8. Rotate the steering knuckle back 90 degrees and pull the drive axle free of the hub.bmw e60 front axle shaft - Pull the drive axle free from the steering knuckle.

 

Section 4 – Removing the BMW E60 front axle shaft from the front differential
The front drive axle is held securely inside the differential with a locking ring that works like a spring, applying pressure to the internal gears so the shaft doesn’t slip out. The locking ring is recessed into the end of the axle shaft in a groove. In order to remove the axle shaft from the differential, it must be “pulled” just enough to release the locking ring’s grip (about 1/2″). Inserting a large flat blade screwdriver or pry-bar into the groove between the axle and the differential will easily force the locking ring to release.

  1. Locate the groove where the drive axle and the differential meet. This is where you will separate them from each other.bmw e60 front axle shaft - Find the groove between the front axle shaft and the differential.
  2. Insert a large flat blade screwdriver into the groove. The screwdriver should have a blade width of about 1/2″. You can also use a small pry-bar if you wish.Try and use a screwdriver with close to a 1/2" blade.bmw e60 front axle shaft - Insert a large flat blade screwdriver into the groove between the drive axle and differential.
  3. Using two hands, start to turn the screwdriver 90 degrees prying the axle away from the differential. You will feel the axle lock ring “pop” out of the differential gears when the blade of the screwdriver reaches 90 degrees.
  4. If you are having a hard time getting the axle to separate from the differential, give the axle a couple good strikes with a hammer and the flat blade screwdriver then try step 3 again.bmw e60 front axle shaft - User a hammer and screwdriver to strike the axle several times if you cant get it separated from the differential..
  5. When the drive axle pops out of the differential, grasp it with your hands and slowly pull it out of the vehicle.bmw e60 front axle shaft - Pull the drive axle out of the differential. bmw e60 front axle shaft - Remove the drive axle from the vehicle behind the steering knuckle.

 

Section 5 – Replacing the BMW E60 front axle shaft seal (optional)
Replacing the axle shaft seal is optional, but strongly recommended by the Repair Guide. The axle shaft seal keeps oil from seeping out of the differential. They are prone to leaking with age, so it only makes sense to replace this inexpensive part now while the axle is removed. Please see our Parts section above if you need to order one. There is no reason to purchase any special tools to reinstall an axle shaft seal…you can fabricate a tool for under $4 with a 2″ PVC coupling and plug from your local home improvement store as shown below.

  1. Locate the front axle shaft seal in the side of the differential.bmw e60 front axle shaft - Locate the front axle shaft seal inside the differential
  2. Remove the old seal by prying it out with a large flat blade screwdriver EXACTLY as shown in the first image below. DO NOT try and pry the seal out any other way…the metal cover is extremely brittle and chips easily. Pry the old seal out of the differential with large screwdriver exactly as shown. bmw e60 front axle shaft - The seal should just pop out of the differential when pried with a screwdriver as shown
  3. Liberally apply fresh lubricant to the inside of the differential and the outside ring of the seal.
  4. Using your fingers, press the new seal into the differential as far as possible. Make sure the seal is lined up straight in the opening and not crooked.bmw e60 front axle shaft - Use your fingers to install the new seal into the opening.
  5. As discussed at the beginning of this section, you DO NOT need any special tools to finish pressing the new seal into the differential. You can easily fabricate your own tool with a 2” PVC schedule 40 coupling and a 2” PVC schedule 40 plug purchased at any home improvement store or our Tools and Supplies list above (see image below). Simply install the plug into the end of the coupling as shown below – you do not have to glue it in.bmw e60 front axle shaft - Use a 2" PVC plug and coupling to make a dive axle seal tool. Insert the plug into the coupling to make an axle shaft seal tool.
  6. Line up the PVC tool on the seal as shown below. Slowly hammer the seal into the differential with a rubber mallet. Hammer around the edges of the tool in circle so equal pressure is put on the seal as it pushes into the differential. Continue lightly hammering until the seal is all the way in.bmw e60 front axle shaft - Line the PVC tool up on the new axle shaft sealbmw e60 front axle shaft - Using a rubber mallet, slowly press the seal into the differential.A fresh seal successfully installed into the differential.

 

Section 6 – Installing the new BMW E60 front axle shaft
Installing the drive axle back into the differential and wheel hub can often be difficult. Years of corrosion can build up on the hub splines, causing the drive axle to bind up and often making it impossible to get the new axle nut on. Getting the locking clip to engage inside the differential can be equally challenging. If you follow our instructions below, you will be able to get the new axle shaft installed with minimal effort.

  1. Liberally apply clean differential lubricant to the shaft of the new drive axle, paying particular attention to the splines and the lock ring at the end of the shaft. Only use a quality 75w90 lubricant from your local parts store or from our parts list above. Avoid using motor oil, transmission fluid, grease or any other type of lubricants that do not match what is already in the differential.bmw e60 front axle shaft - Liberally apply lubricant to the axle shaft.
  2. Slowly install the new drive axle into the differential. Be aware that the splines on the end of the axle shaft must line up with gears inside the differential. Once the splines are lined up, push the axle into the differential as far as it will go. You will most likely not be able to get the locking clip to snap into place…it is very tight and will need a bit of force to get it to compress (see next step). Turn the axle back and forth a couple times to make sure the splines are lined up and properly engaged in the differential gears.Install the new axle shaft into the differential.
  3. The axle shaft lock ring should snap into the differential gears if you follow these easy steps. First, thread the axle nut on the end of the axle shaft so you have a nice solid place to push.bmw e60 front axle shaft - Thread the hub nut onto the axle shaft. bmw e60 front axle shaft - This gives a nice sturdy base to push.
  4. Straighten out the axle and push it in so it compresses. With the axle straight and compressed, forcefully strike the end of the axle with the palm of your hand until the lock ring snaps into place in the differential (it took us three strikes). NEVER use a hammer or any other tool to strike the end of the axle shaft. ALWAYS keep the shaft straight…never strike it when it is at an angle.Make sure the axle shaft is completely straight and compressed. bmw e60 front axle shaft - Strike the end of the axle shaft several times with the palm of your hand to snap the locking clip into the differential.
  5. Next, liberally apply a penetrating lubricant like Blaster PB to the hub splines. Use a metal brush to thoroughly clean the splines. Repeat this several times to make sure the hub splines are free of any dirt and corrosion.bmw e60 front axle shaft - Thoroughly soak the hub splines with a penetrating lubricant. bmw e60 front axle shaft - Use a metal brush to thoroughly clean the hub splines. Thoroughly clean the hub splines.
  6. Apply a generous amount of waterproof grease to the hub splines with your finger.Always use a quality waterproof grease bmw e60 front axle shaft - Apply a generous amount of waterproof grease to the hub splines with your finger.
  7. Next, liberally apply waterproof grease to the splines on the axle shaft. Try not to get any grease on the axle nut threads…wipe off any excess that finds their way onto them. The axle nut can possibly become over-torqued if there is an excess of lubrication on its threads.

  8. Grab the steering knuckle and pull it away from the car. Line up drive shaft and insert it into the hub. If the splines will not line up, rotate the axle with your hand until they do. Push the axle as far as you can into the hub. You should be able to get enough in so about ⅛” protrudes from the wheel hub.bmw e60 front axle shaft - Install the new axle shaft into the hub Push the shaft in as far as it will go.
  9. Using a 4lb hammer and a block of wood strike the wheel hub. Continue to forcefully strike the block of wood until the axle threads protrude out enough to get the axle nut on 1/2 turn. Use a rag to thoroughly wipe off any grease from the threads. Install the axle nut hand tight.bmw e60 front axle shaft - Clean the axle shaft threads with a rag. make sure to remove all of the grease and oil from them. bmw e60 front axle shaft - Install the new axle nut hand tight.
  10. Use a 36mm (or 32mm on some newer axle nuts) 12 point socket to slowly tighten the nut. Keep tightening slowly until the axle is pulled all the way into the hub. DO NOT torque the axle nut yet. This will be done after the car is lowered on its wheels.bmw e60 front axle shaft - Slowly tighten the axle nut pulling the axle into the hub.

 

Section 7 – Final reassembly
Final reassembly of the vehicle after installing the new axle is very straightforward except for one extra important step; the front end of the vehicle must be “loaded” when you torque the control arm bushing bolts. We know this sounds confusing, but it is actually very simple. You must put the full weight of the car on the front wheels before torquing the control arm bushing bolts or the bushings can bind up, greatly reducing their service life and causing possible damage to the front end of the vehicle. You DO NOT have to load the front end when torquing the control arm ball joint nuts.

  1. Reinstall the splash guard inside the fender well using the 8mm screws.
  2. Install the wheel speed sensor back into the steering knuckle and torque its mounting bolt to 8 Nm (6 ft-lb).
  3. Reinstall the lower control arm ball joint and its mounting nut. Torque the mounting nut to the following value: 165 Nm (122 ft-lb). ***This may seem like a lot of torque, but it is the correct value for the M14 ball joint nut. DO NOT torque the lower control arm bushing bolt yet…that will be done in step 7 below.bmw e60 front axle shaft - Torque the lower control arm ball joint nut to 165Nm (122 ft-lb).
  4. Reinstall the upper control arm (tension strut). If working on the right wheel, replace the headlight level sensor on the control arm. Torque the mounting nut to the following value: 165 Nm (122 ft-lb). Once again…we know it’s a lot of torque but the value is correct.
