Part of front wheel housing

Part of front wheel housing

Joint in front of MacPherson strut tower

Replacement of front frame member see, Part of front frame member (joining) and Front wheel housing and front frame member (full replacement).

The radiator member should first be removed.


1. Mount the car on an aligning bench.


2. Realign the car to the correct measurements if necessary.

3. Left wheel housing:

Drill out the spot welds on the battery tray. Knock loose the tray and remove. Grind away the seam welding.

4. Roughly cut away the damaged part of the wheel housing.


5. Drill out the spot welds securing the damaged part of the wheel housing.


6. Knock loose the damaged part of the wheel housing. Realign any deformed metalwork.

7. Cut the new wheel housing roughly to size so that it will overlap the joint by about three centimetres.


8. Fit the spare part in position. Align it with the hole in the existing wheel housing and fix it with a couple of welding clamps. Adjust the position of the spare part exactly, checking the alignment by means of the aligning bench's coordinate measuring system.

9. Cut through both the spare part and the existing wheel housing simultaneously so that the joint can be welded edge- to-edge.

10. Remove the spare part.

11. Use a grinder to clean the areas on the body and the new part of the wheel housing that are to be welded.

12. Apply welding primer to the surfaces which are to be spot welded. Use Teroson Zinkspray.

13. Position the new part of the wheel housing. Align it with the hole in the existing wheel housing and then fix it with a couple of welding clamps.

14. Secure the new wheel housing with a couple of tack welds.

15. Fit wing, radiator member and bonnet in position. Check the position of the wheel housing. Adjust as necessary.

16. Weld the joints on the wheel housing. The upper part of the joint should be welded from the inside and the lower part from the outside.


17. Grind the welds clean.

18. Spot weld the wheel housing to the frame member.


19. Left-hand wheel housing: Use a grinder to clean the areas on the battery tray and the wheel housing that are to be welded.


20. Left-hand wheel housing: Apply welding primer to the surfaces that are to be spot welded. Use Teroson Zinkspray.

21. Left-hand wheel housing: Weld the battery tray to the wheel housing.

22. Weld the end plate to the front edge of the wheel housing after welding the frame member to the front cross member.


23. Wash off surplus welding primer. Welding primer makes for poorer adhesion of paint, filler and sealant.

24. Apply primer to all surfaces which have been ground clean. Use Standox 1K Füllprimer.

25. Apply anti-corrosion agent to the inside of the wheel housing after it has been painted. Use Terotex HV 400 or Mercasol 1.
