Disassembly
Note! Preparatory work, left-hand side: See Replacing the front left drive shaft Drive Shaft Left, Replacing. Preparatory work, right-hand side: See Replacing the front right drive shaft Drive Shaft Right, Replacing.
Note! The inner constant velocity joint must not be split.
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 measurements
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 bearing race or outer ring.
Cleaning the constant velocity joint housing
The joint can be cleaned when assembled. See Cleaning the constant velocity joint housing - continued.
If the joint needs to be disassembled, see Cleaning/checking the outer constant velocity joint.
Cleaning the constant velocity joint housing - continued
Thoroughly clean off any dirt and grease from the joint. Blow the joint dry.
For greasing/assembling see Assembly.
When replacing the inner boot
Remove the clamps from the inner boot. Cut the boot and remove it from the shaft.
Note! Clean and blow the inner constant velocity joint dry while assembled.
For greasing/assembling see Assembly.
Cleaning/checking the outer constant velocity joint
Marking the 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.
Removing the constant velocity joint ball bearings
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 Marking the constant velocity joint.
Place the ball bearings in order so that they can be reinstalled in the same positions.
Removing the bearing race and inner ring
Remove the bearing race and the inner ring from the shaft.
Turn the inner ring 90 degrees in relation to the bearing race.
Remove the inner ring.
Cleaning constant velocity joint components
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.
Installing the inner ring
Install the inner ring in the bearing race.
Line up the markings with each other. Install a ball bearing.
Note! Note the position of the ball bearings.
Turn the inner ring and the bearing race.
Install the balls one by one in the same positions as before. See Removing the constant velocity joint ball bearings.
Assembly
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 gaiter. See Assembling the drive shaft boot.
Installing the snap ring
Replace the snap ring.
Install the new snap ring included in the boot kit.
Installing boots and the constant velocity joint
Install:
- the new boot(s) on the drive shaft
- 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 Checking the measurements.
Assembling the drive shaft boot
Apply grease in 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 Replacing the front left drive shaft Drive Shaft Left, Replacing.
For the right-hand side, see Replacing the front right drive shaft Drive 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.
