B-pillar, separate spare parts

B-pillar, separate spare parts

To remove

Depending on the damage, the B-pillar can be replaced with two alternative spare part configurations. The method below uses separate spare parts (monoside and B-pillar reinforcement). For replacement of the B-pillar complete side with reinforcement, see.


1. Cut the B-pillar in accordance with the marking. Cut through all panel layers.


2. Cut the rear sill as illustrated. Cut only through the outer panel.

3. Cut the front sill as illustrated. The cut can be made within the marked area. Cut only through the outer panel.

4. Drill out the spot welds on the sill.

5. Cut the B-pillar inner panel from the inside of the car as illustrated.


6. Tap out the outer sill and the B-pillar together with the reinforcements.

7. Protect the roof from welding and grinding splatter.

8. Cut the upper section of the B-pillar's outer panel as illustrated. Measure from the measurement points.


9. Cut the upper section of the B-pillar's outer panel as illustrated.


10. Drill out the spot welds. Tap the section away.

11. Drill out the spot welds at the roof through the roof panel and outer panel.


12. Carefully tap up the edge of the roof and drill out the spot welds on the remaining section of outer panel. Tap the section of outer panel away.

13. Drill out the spot welds for the B-pillar reinforcement. Carefully tap away the reinforcement.


14. Mark out the positions on the inside of the B-pillar's upper and lower sections in order to facilitate fitting.

15. Drill out the spot welds on the inside of the B-pillar's upper section. Tap the section away.


16. Drill out the spot welds on the inside of the B-pillar's lower section. Tap the section away.


17. Drill holes for plug welding in the spare part, the inside of the B-pillar.

18. Grind all surfaces that are to be plug welded.

19. Apply welding primer to all surfaces that are to be plug or spot welded.

20. Align the inside of the B-pillar using the earlier markings.

21. Weld in the inside of the B-pillar at the lower edge. Grind in the welds


22. Weld in the inside of the B-pillar at the upper edge. Grind in the welds.

23. Drill holes for plug welding in the upper section of the B-pillar reinforcement.


24. Align the B-pillar reinforcement using the earlier markings.

25. Spot weld and plug weld the upper section of the B-pillar reinforcement.

26. Spot weld and plug weld the lower section of the B-pillar reinforcement.


27. Grind the welds.

28. Cut the new outer panel so that it corresponds with the earlier cutting work.


29. Drill holes for plug welding on the bottom and side of the outer panel.


30. Grind all surfaces that are to be welded.

31. Apply welding primer to all surfaces that are to be plug or spot welded.

32. Align the outer panel by inserting it under the roof, rear and front sills.

33. Plug weld, all-weld and seam weld the spare part in at the upper edge against the roof. Grind in the welds.

34. Spot-weld the spare part.

35. Tap down the edge of the roof against the outer panel and the B-pillar reinforcement. Plug weld the drilled-out holes.

36. Securely all-weld the front sill reinforcement.


37. All-weld the rear sill.

38. All-weld the upper section of the B-pillar.

39. Grind the welds.

40. Wash away surplus welding primer. Welding primer reduces the adhesion of paint, filler and sealant.

41. Apply primer to all bare metal surfaces.

42. Seal joints and seams with sealant.

43. Apply rust protector after painting. Use Terotex HV 400.
