306 XSI 16v - Rear Suspension problem

Oct 13, 2004 4 Replies

Hi guys,



I need help. My car's rear suspension is very very soft. I have replaced the shocks twice over a 2 month period and still no improvement. What could be the cause? I really feel it is the actual torsion( mind the spelling ) bar.. What do I do? Blow the car up with some C4.



Apart from tyre pressures, or maybe some problem at the front which makes the rear feel soft, I don't seem what else it could be other than the torsion bars. Will watch this thread with interest.

Q. The handling of my Peugeot has become unpredictable and it sometimes feels like the rear end is wandering during cornering. What is wrong?

A. There are two possibilities here, and both need resolving immediately:

  1. Check the rear sub-frame rubber mounts as they often split in half, particularly on older models.
  2. Check for play in the trailing arm bearings. These are the bearings that the trailing arm pins locate in, inside the rear suspension tube. They allow the trailing arms to move up and down smoothly. They regularly wear out, particularly if moisture has got inside the bearing tube. You can test for play with the car raised off the ground at the rear - try and move the wheel in and out of the wheel arch. It should only move up and down, not in and out (small movement of the wheel when grasped either side could be a worn wheel bearing). Replacement of the bearings is a specialist job. Often the bearing surface of the pins will be worn as well, and if so, they must be replaced. It will probably be more cost effective to replace the whole sub-frame with a reconditioned unit. Beware when buying 2nd hand sub-frames, as the bearings are generally in poor condition once past 5-6 years old.

I hope this will help others!

Trailing arms or suspension, here's what it looks like, and these people know all about fixing it:
