- Remove large clamp and pull back CV boot.
- Using a hammer and a copper or brass drift, drive off inner ring of constant velocity joint.
Ventilating CV joint boot

Tightening clamp on outer joint
- Apply CV joint boot clamp tool V.A.G 1682 as shown. Make sure jaws of tool make contact with lugs - arrows B - on clamp.
- Tighten clamp by turning spindle with torque wrench (take care to keep pliers straight).
^ Tightening torque: 20 Nm.
^ Use torque wrench with 5 to 50 Nm range (e.g. torque wrench V.A.G 1331).
^ Make sure spindle thread on pliers moves freely. Lubricate with MoS2 grease if necessary.
^ If the thread is stiff (e.g. due to dirt), the required clamping force will not be attained at the clamp when applying specified tightening torque.
