Fits: Audi A4 Cabriolet B6/B7 (8H), Audi A4 B6/B7 (8E)

Don't miss

• Remove drive shaft grease and mark installation position of constant velocity joint relative to drive shaft.
• A second person must hold the drive shaft horizontal to prevent the constant velocity joint from being damaged.
• Chamfer on internal diameter of ball hub (splines) must face drive shaft.

📋 Procedure

1. Clamp drive shaft in vice.
2. Drive off cover with a copper or brass drift.
3. Remove circlip.
4. Remove drive shaft grease and mark installation position of constant velocity joint relative to drive shaft.
5. Clamp constant velocity joint with drive shaft in vice, as shown in illustration.

6. A second person must hold the drive shaft horizontal to prevent the constant velocity joint from being damaged.
7. Open out rim (arrow) of cap slightly using a small chisel.
8. Drive off cap with a copper or brass drift.
9. Press constant velocity joint off drive shaft.
