Remove the boot
Secure the drive shaft in a vise with soft jaws.
Remove the clamps from the boots.
Cut the boot and remove it from the shaft.
Check dimensions
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.
Tap off the constant velocity joint housing
Use a brass drift.
Note! Only tap the inner ring. Take care not to damage the bearing race or outer ring.
Remove 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. 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 Install the inner ring in the bearing race, Lubricate the constant velocity joint thoroughly, Replace the snap ring, Install the new boot(s) on the drive shaft, Apply grease in the boot and Vent the boot.
Cleaning / checking the outer constant velocity joint
Mark the outer ring, bearing race and inner ring on the outer constant velocity joint.
Mark components in relation to each other.
Use an electric scriber.
Remove the ball bearings
Turn the constant velocity joint inner ring and bearing race. Remove the ball bearings clockwise one by one.
Use the marking as the starting point when removing. See bearing race and inner ring on the outer constant velocity joint.
Place the ball bearings in order so that they can be reinstalled in the same positions.
Remove the bearing race and the inner ring from the shaft
Turn the inner ring 90° in relation to the bearing race.
Remove the inner ring.
Wash 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 bearing races are permitted.
Install the inner ring in the bearing race
Line up the markings with each other. Install a ball bearing.
Note! Ball location.
Turn the inner ring and the bearing race.
Install the balls one by one in the same positions as before. See Remove the ball bearings.
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 gaiter. See Apply grease in the boot.
Replace the snap ring
Install the new snap ring included in the boot kit.
Assembly
Install the new boot(s) 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 lock ring is seated in its groove. Do this by measuring the distance. See Check dimensions.
Apply grease in the boot
Apply the remaining grease from Lubricate the constant velocity joint thoroughly.
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.
Vent 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.
