Removal
Remove the wheel cap.
Unscrew the hub mounting nut on the drive shaft.
Note: The vehicle must be on the ground.
Remove the washer
Loosen the wheel bolts.
Raise the car.
Remove the wheel.
Remove the drive shaft cover.
Remove the internal slotted bolt on the internal joint -arrow-. To do this, you will need a socket for the internal slotted bolt. For example, HAZET 990 Lg-8, for a 100 kW engine; Lg-10.
Press the drive shaft away from the flange.
Power steering vehicles only
Unscrew the nut from the connecting rod -arrow- on the left.
Remove the lever and beam mounting bolts.
Press the lever down.
Caution: When removing the drive shaft, ensure that there is free play between the inner constant velocity joint and the gearbox. If necessary, remove the ball joint "23" in Fig. 40-760 from the steering knuckle. To do this, unscrew and remove the tie bolt.
Press the drive shaft out of the hub with a puller. It may not be possible to press the drive shaft out with a regular puller, as it is coated with D6 protective agent. In this case, the drive shaft should be removed with a hydraulic device
Caution: When removing the drive shaft, do not heat the hub under any circumstances, otherwise the hub bearing may be damaged. Be sure to use a removal tool.
Secure the VAG 1389 removal tool to the hub with two bolts.
Press the drive shaft out of the hub using a tool.
Remove the removable device.
Caution: When the drive shaft is removed, the engine of the car must not be started, since the hub bearing may be damaged in the absence of axial load. If necessary, install an external constant velocity joint instead of the drive shaft. For cars with servo control, the lever must be screwed to the beam and to the connecting rod.
Manual transmission vehicles only
Mark the position of the ball joint relative to the lever with a chisel. This will eliminate the need to check and adjust the camber.
Unscrew the ball joint from the lever.
Remove the drive shaft.
Installation
Before installation, clean the gear engagement of the drive shaft and hub with gasoline and remove all traces of protective agent.
Caution: On vehicles with power steering, be careful not to damage the housing when installing the right drive shaft.
Coat the splines of the outer hinge gear for 5 cm with protective agent D6.
Insert the drive shaft into the hub and secure with the old nut. Do not tighten the nut.
Install the drive shaft into the gearbox.
Tighten the inner constant velocity joint internal spline bolts crosswise. Don't forget the shim.
Tightening force:
- m8 bolts: 45 Nm;
- m10 bolts (100 kW engine): 80 Nm.
Only vehicles with mechanical steering
Use pliers to set the ball joint to the parking position and tighten the new self-locking nuts to 65 Nm.
Caution: When screwing the ball joint to the lever, do not damage the constant velocity joint housing.
Power steering vehicles: Bolt the arm to the beam and connecting rod using new bolts and nuts. Do not tighten the nuts.
If it was removed, insert the ball joint into the steering knuckle and tighten the bolt to 65 Nm.
Screw on the wheel.
Lower the car.
Tighten the wheel bolts to 110 Nm.
Unscrew the nut from the drive shaft and screw on a new self-locking nut with a torque of 265 Nm. Do not forget the washer. Pre-coat the thread with VAG D6 protective agent.
Note: The vehicle must be on the ground.
Vehicles with power steering: Tighten the new self-locking nuts of the control arm on the beam to 65 Nm. Tighten the new self-locking nut of the connecting rod to 20 Nm.
Install the cap.
If necessary, check wheel alignment.
