Clamp clip 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).

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.

Assembling

Pressing on inner constant velocity joint

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

  • Coat sealing surface of cover with -D 454 300 A2- .
  • Apply continuous bead of sealant with √Ш 2...3 mm past inner edge of holes -arrow- to clean surface of cover.

  • Align the new cover with its bolts -arrows- with the corresponding 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.
  • Wipe off any excess sealant.

Clamp clip on outer joint

  • Apply special pliers -V.A.G 1682- as shown in diagram. 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).

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.

  • 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.
