Disassembly
Note! Preparations: See Drive shaft right, replacing Drive Shaft Right, Replacing and Drive shaft right, replacing Drive Shaft Right, Replacing.
Secure the drive shaft. Remove the boot
Secure the drive shaft as close to the bearing as possible.
Note! Do not over tighten. The shaft is hollow.
Remove the clamps from the boot. Press the outer section of the shaft inwards forcefully. At the same time pull the boot off the joint.
Note! Take care that the shaft does not separate when the boot is removed from the constant velocity joint. The joint has no axial pinion.
Clean and mark up the constant velocity joint
Wipe off the grease from the joint.
Mark up the constant velocity joint, ball holder and shaft in relation to each other.
Use an electric scriber.
Separate the shaft and pull out the inner joint
Place the shaft on a workbench. Carefully separate the shaft by pulling out the inner joint from the constant velocity joint. At the same time, note the position of the balls in relation to the markings. See Clean and mark up the constant velocity joint.
Replacing the pilot bearing
Press out the pilot bearing from the drive shaft
Use jointed ring 999 2853 RING JOINTED 999 2853 Ring Jointed. Support the socket and shaft as illustrated.
Install the new bearing on the shaft
Use press ring 999 5491 PRESS TOOL 999 5491 Press Tool as support against the bearing. Turn it as illustrated.
Position socket 999 2842 SOCKET 999 2842 Socket at the base of the universal joint.
Press the bearing against its seating on the shaft.
Replacing the boot
Note! Only when replacing the pilot bearing
Knock of the joint's inner track
Secure the shaft in a vice.
Position a drift between snap ring wings. Knock of the joint inner cone. Modify the drift.
Remove the old boot from the shaft. Install a new one
Check the inner track snap ring. Replace if necessary.
Tap the inner bearing track on to the joint. Use drift 999 2413 PUNCH 999 2413 Punch.
Check that the snap ring is seated in its groove.
Checking and inspection
Clean the inner drive shaft components thoroughly.
Reassembly
Assemble the inner joint
Use measurements according to Clean and mark up the constant velocity joint.
Position the outer section of the shaft vertically in a vice.
Lubricate the constant velocity joint ball track. Also apply grease in the bottom of the housing.
Use half of the grease in the joint. The rest of the grease will be used in the boot, see Apply grease in the boot.
Hold up the ball holder so that the balls are as high up as possible without falling in towards the middle.
Hold the balls in this position.
Install the inner section of the shaft
Carefully install the inner section of the shaft with the universal joint according to the markings made previously. See Clean and mark up the constant velocity joint. Press the shaft sections together.
Position the shaft assembly horizontally.
Apply grease in the boot
Secure the inner section of the shaft in a vise.
Note! Take care that the joint does not separate.
Apply the rest of the grease (from the tube) in the boot. Ensure that there is no grease on the mating surfaces between the boot or the drive shaft and the constant velocity joint. Clean off excess grease with denatured alcohol.
Press the boot onto the constant velocity joint
Ensure that it is in position.
Install the new clamp. Use pliers 951 2619 Pliers 951 2619 Pliers.
Check that the boot is in position on the drive shaft
Use a well rounded screwdriver.
Carefully insert the screwdriver between the drive shaft and boot. Ensure that the boot is in position on the drive shaft (the inner rib against the joint).
Install a new clamp. Use pliers 951 2619 Pliers 951 2619 Pliers.
Install the drive shaft in the transmission
