Don't miss

• The flexible pipe connection (de-coupling element) in the front exhaust pipe must not be bent more than 10° - otherwise it can be damaged.
• A second mechanic is required for removing the rear section of the exhaust system.
• Check whether there is a factory marking (coloured dot) (arrow A) and (arrow B) on the propshaft and on the propshaft flange on the rear final drive.
• If one of these markings is no longer visible (for example (arrow A) on the propshaft), make a new coloured marking accordingly.
• Use counterhold tool T10172 with adapters T10172/5.

📋 Procedure

1. Place vehicle on lifting platform. [Note: The flexible pipe connection (de-coupling element) in the front exhaust pipe must not be bent more than 10° - otherwise it can be damaged.]
2. Unfasten clamp(s) (arrows) and disconnect exhaust system.
3. Tie front exhaust pipe(s) up to side of underbody.
4. If fitted, remove rear cross member (1).
5. Remove rear section of exhaust system (2)26Exhaust pipes/silencers; Exploded view - silencers. [Note: A second mechanic is required for removing the rear section of the exhaust system.]

6. Detach heat shield (3) from body (arrows).
7. Check whether there is a factory marking (coloured dot) (arrow A) and (arrow B) on the propshaft and on the propshaft flange on the rear final drive.
8. If one of these markings is no longer visible (for example (arrow A) on the propshaft), make a new coloured marking accordingly.
9. Remove bolts (1) (6x) on rear CV joint.
10. Use counterhold tool T10172 with adapters T10172/5.
11. If removed, re-attach rear cross member (C) to body.
12. Place a block of wood (A) (approx. 40 mm high) on rear cross member (C) to support propshaft (B). [Note: On the Audi Q5, the propshaft (B) is supported by the heat shield below the centre bearing.The propshaft can be bent as far as the stop at the centre joint, but must not be subjected to any kind of force. The centre joint or the protective boot can be damaged if the joint is forced against its stop.]
13. Remove bolts (arrows) securing centre propshaft bearing.
14. Push propshaft forwards and at the same time pull it off rear final drive.
15. Tie propshaft up to one side on subframe.
16. Detach heat shield (A) for drive shaft (left-side) from cross member/rear final drive (arrows).
17. Unbolt drive shafts on both sides (1) and (3).
18. Slacken off bolts (2) approx. 3 turns.
19. Remove bolt (4).
20. Place engine and gearbox jackV.A.G 1383 A with universal gearbox supportV.A.G 1359/2 and a suitable block of wood (A) (approx. 80 mm high) below rear final drive. [Note: Make sure that universal gearbox supportV.A.G 1359/2 does not make contact with fuel tank.]
21. Remove bolts (1) (bottom bolts securing cross member to rear final drive) and (2).
22. Remove 2 top bolts securing cross member (B) to rear final drive.
23. For this step, guide socket T40154 through holes in subframe (A). If necessary, move final drive slightly to either side.
24. Then push final drive (A) slightly forwards.
25. Turn cross member (B) towards the bottom left (arrow 1), guide past final drive (arrow 2) and remove. [Note: A 2nd mechanic is required for the next steps when removing the rear final drive.]
26. 2nd mechanic must now lift right side of rear final drive (1) slightly and push it towards left side of vehicle in direction of (arrow). [Note: The top part of the illustration "“I”" shows the rear final drive without engine and gearbox jackV.A.G 1383 A and universal gearbox supportV.A.G 1359/2.]
27. Guide drive shaft (right-side) (5) upwards out of flange shaft (right-side) (4) of rear final drive.
28. Then guide out drive shaft (left-side) (3).
29. Secure rear final drive with strap (B).
30. Lower rear final drive completely.
31. Using engine and gearbox jackV.A.G 1383 A with universal gearbox supportV.A.G 1359/2, bring rear final drive (1) into position on subframe (2). [Note: The top part of the illustration "“I”" shows the rear final drive without engine and gearbox jackV.A.G 1383 A and universal gearbox supportV.A.G 1359/2.]
32. Fit drive shaft (left-side) (arrow 3) into flange shaft of final drive.
33. 2nd mechanic must now lift right side of rear final drive (1) slightly and push it towards left side of vehicle in direction of (arrow).
34. Then fit drive shaft (right-side) (5) into flange shaft (right-side) (4) of final drive.
35. Then push final drive (A) slightly forwards.
36. Turn cross member (B) towards top left in opposite direction to (arrow 1) and bring into position, guiding past final drive (arrow 2).
37. Tighten 4 bolts securing cross member (B) to rear final drive in diagonal sequence to specified torque .
38. For this step, guide socket T40154 through holes in subframe (A). If necessary, move final drive slightly to either side.
39. Screw in bolts (2) and (4) and tighten hand-tight initially. [Note: For illustration purposes the final drive is shown without engine and gearbox jackV.A.G 1383 A and universal gearbox supportV.A.G 1359/2.]
