Rear Suspension Problem

[newgraden]

Hi I have just bought a C5 2.2 HDI Estate 2001. When we took it for a test run from a private seller it seemed fine and we fell in love with it but soon after getting it home their became a knocking noise from the back (like loud clicking) I took it to the local garage and the put it up on to the ramps (if you bounce hard on the back end you can hear the noise) They had four people under the car and no one could locate exactly where the clicking was coming from? The suspension work properly and it clicks when on bumpy roads or some times turning corners. It was booked in to the local garage twice but came back just the same, so I decided to take it to Citroen they fixed something on the front roll bar and said that would be it fixed and the noise was from the front, but as soon as I left the garage it was still the same, Citroen then said they would have another look. Even They cannot pinpoint the noise (I think it might be something seized as It lay for just over 3 months over the winter before they sold it) so they have suggested the only thing I can do is replace all the back suspension arms wishbones and back axle at a cost of just under £2000. I love the car to bits but cannot afford this as I am on a low income. Has anyone any suggestions on what it could be or anyone else had this problem and found out what it was. Thank you for any help. Angela

It could be the rear arm bearings. C5's - and before them the Xantias and before them the BX's - they all had similar rear suspension and all developed wear in the arm bearings. Put your suspension on high then stand some distance from the rear of the car. If the rear wheels are looking a bit like this:- /-------\ then you can be sure the arm bearings have gone. Grinding noise when the suspension moves is also indicative.

Thank you very much for this. I will have a look tomorrow.
