Removal
Note! Preparatory work, left-hand side: See Drive shaft left, replacing, B5254T2, M58, B5254T2, M56 Drive Shaft Left, Replacing.
Note! Preparatory work, right-hand side: See Half shaft, right, replacing, B5254T2, M58, B5254T2, M56 Half Shaft, Right, Replacing.
Removing the boot
Secure the drive shaft in a vice with soft jaws.
Remove the clamps from the boots.
Cut the boot and remove it from the shaft.
Checking the dimension
Wipe off the grease from the constant velocity joint housing.
Measure the distance from the inner ring to the inner groove on the shaft. Note the measurement.
Removing the constant velocity joint housing
Tap off the constant velocity joint housing.
Use a brass drift.
Note! Only tap the inner ring. Take care not to damage the ball holder or outer ring.
Removing the clamp from the inner boot (if the boot is being replaced)
Cut the boot and remove it from the shaft.
Note! The outer constant velocity joint can be cleaned while assembled. For checking and cleaning see Cleaning / checking the outer constant velocity joint.
Note! The inner constant velocity joint can be cleaned while assembled and blown clean prior to greasing.To disassemble the joint, see Replacing the right drive shaft pilot bearing Service and Repair , Replacing the right drive shaft pilot bearing Service and Repair and Replacing the right drive shaft pilot bearing Service and Repair.
To assemble and lubricate the outer joint:
See Installing the inner ring in the ball holder, Lubricating the constant velocity joint, Replacing the circlip, Installing new boots on the drive shaft, Greasing the boot and Venting the boot.
Cleaning / checking the outer constant velocity joint
Marking the outer ring for the outer constant velocity joint, ball holder and inner ring
Mark components in relation to each other.
Use an electric scriber.
Removing the balls
Turn the inner joint ring and ball holder. Remove the ball bearings clockwise one by one.
Use the marking as the starting point when removing. See ball holder and inner ring.
Place the ball bearings in order so that they can be reinstalled in the same positions.
Removing the ball holder and inner ring from the drive shaft
Turn the inner ring 90° in relation to the ball holder.
Remove the inner ring.
Cleaning constant velocity joint components
Clean the constant velocity joint components thoroughly
Note! Replace the drive shaft assembly if any component has cracking or wear damage. Scratches and minor pitting of the ball tracks are permitted.
Installing the inner ring in the ball holder
Install the inner ring in the ball holder.
Locate the markings to each other. Install a ball bearing.
Note! Ball location.
Turn the inner ring and the ball bearing holder.
Install the balls one by one in the same positions as before. See Removing the balls.
Lubricating the constant velocity joint
Lubricate the constant velocity joint thoroughly.
Apply grease behind the joint via the shaft hole in the inner ring.
Use half of the grease packet. The remainder will be used later in the boot. See Greasing the boot.
Replacing the circlip
Install the new snap ring included in the boot kit.
Installation
Installing new boots on the drive shaft
Install the constant velocity joint on the drive shaft
Ensure that inner ring is straight in the constant velocity joint.
Tap on the constant velocity joint. Use a rubber mallet.
Check that the snap ring is seated in its groove. Do this by measuring the distance according to Checking the dimension.
Greasing the boot
Grease the boot.
Apply the remaining grease from Lubricating the constant velocity joint.
Note! Ensure that there is no grease on the mating surfaces between the boot and the constant velocity joint and the shaft.
Remove excess grease. Use methylated spirit.
Ensure that the boot is in position on the constant velocity joint housing.
Install a new clamp. Use pliers 951 2619 Pliers 951 2619 Pliers.
Venting the boot
Venting is carried out to remove any over pressure in the boot. Use a rounded screwdriver.
Carefully insert the screwdriver between the drive shaft and boot. Ensure that the boot is in position on the drive shaft.
Ensure that the boot is aligned against the inner rib on the drive shaft.
Install a new clamp. Use pliers 951 2619 Pliers 951 2619 Pliers.
Install the drive shafts
For the left-hand side, see Drive shaft left, replacing, B5254T2, M58, B5254T2, M56 Drive Shaft Left, Replacing.
For the right-hand side, see Half shaft, right, replacing, B5254T2, M58, B5254T2, M56 Half Shaft, Right, Replacing.
Spray wax, part number 30787812, on the outer gaiter. After installing drive shaft in vehicle, turn the wheel and check, and improve if needed, the wax protection on the gaiter.
