Servicing drive shaft with 90 mm dia. outer constant velocity joint — AUDI

🧭 Before you start

Fits: Audi A3 (8V, 2012–2020); platform code 85

• Special tools named: torque wrench

Don't miss

• Chamfer on internal diameter of ball hub (splines) must face contact collar of drive shaft.
• Apply clamp tensionerV.A.G 1682 A as illustrated. Ensure jaws of tool make contact with lugs (arrows B) on hose clip.

📋 Procedure

1. Drive joint off drive shaft with a firm blow from an aluminium hammer.
2. Grease splines (arrow A) on drive shaft lightly with grease used in joint before fitting joint body onto drive shaft.
3. Screw old bolt into CV joint as shown.
4. Use plastic-headed hammer to drive joint onto shaft until circlip engages.
5. Grease splines (arrow A) on drive shaft lightly with grease used in joint before fitting joint body onto drive shaft.

6. Apply special tools as shown in illustration. [Note: Chamfer on internal diameter of ball hub (splines) must face contact collar of drive shaft.]
7. Fit circlip.
8. Apply sealant (hatched area) on clean inner surface of cap on CV joint boot. Sealant bead: continuous, 2 ... 3 mm ∅. Route around inside of holes (arrow).
9. Use sealant as listed in Electronic parts catalogue.
10. Push joint boot onto drive shaft.
11. Using bolts (arrows), align CV joint boot with cap in relation to bolt holes.
12. Drive on CV joint boot with cap using a plastic hammer.
13. Remove surplus sealant immediately as it is pressed out.
14. Apply clamp tensionerV.A.G 1682 A as illustrated. Ensure jaws of tool make contact with lugs (arrows B) on hose clip.
15. Tighten hose clip by turning spindle (A) with torque wrench (take care to keep clamp tensioner straight). [Note: Make sure thread of spindle (A) turns freely. Lubricate with Mo S2 grease if necessary.If the thread is stiff (e.g. due to dirt), the required clamping force will not be attained at the hose clip when the specified tightening torque is applied.]
