Dismantling

Driving out constant velocity joint

  • Clamp drive shaft in vice using protective jaw covers.
  • Remove clamps.
  • Push the dust guard backwards.
  • Remove the constant velocity joint from the drive shaft using an awl -A-.

Drift must be positioned exactly on ball hub of constant velocity joint.

Position the seal

Rear suspension

Installation position of dished spring at outer joint

  1. - Dished spring
  • Fit new circlip.
  • Use plastic-headed hammer to drive joint onto shaft until circlip engages.

Separate cover for inner constant velocity joint

Rear suspension

Pressing off inner constant velocity joint

  • Separate the dustguard of the constant velocity joint with a punch.
  • Remove circlip.
  • Remove both clamps and slide boot towards outer joint.

Assembling

Installation position of the plate spring on the joint

  1. - Dished spring

Pressing on inner constant velocity joint

Note Chamfer on internal circumference of ball hub (splines) must face contact shoulder on drive shaft.

  • Insert the constant velocity joint up to the limit.
  • Install retaining ring.

  • Using bolts -arrows-, align new cover in relation to bolt holes.

The alignment must be very accurate, because no further alignment is possible once the part has been hammered on.

  • Drive on cover using a plastic hammer.

Tighten clamp on outer joint

  • Apply clamp tensioner - V.A.G 1682- as illustrated. Ensure jaws of tensioner lie in corners -arrows B- of clamp.
  • Tighten hose clip by turning spindle with torque wrench (take care to keep clamp tensioner straight).

Rear suspension

Note

  • Due to the hard material of the protective boot (compared to rubber) and the necessity of using a stainless steel clamp, it is only possible to tension the clamp with clamp tensioner - V.A.G 1682- .
  • Tightening torque: 25 Nm.
  • Use a torque wrench -C- with a range between 5 ... 50 Nm (e.g torque wrench - V.A.G 1331- ).
  • Check that the spindle thread -A- of the pliers is easily movable.

    Apply MOS 2 grease if necessary.

  • If the thread is tight (e.g. due to dirt), the required clamping force for the clamp will not be attained although the specified tightening torque is applied.
