Annoying Rattle

[Jonno]

My 2.0 HDi has developed an annoying rattle when going over bumps in the road, a smooth road and theres no rattle at all, but it seems to be coming from drivers front side. I thought initially it was a bottom ball joint loose but that checked out fine. Another thought was the anti roll bar joints etc but they too are tight. I know noises are inherently difficult to trace but the best description I can give is it does in fact sound like an anti roll bar joint loose. Checked all suspension attachments and cant find any play anywhere, also checked security of plastic underpan etc and thats fine. The annoying thing is it is just a knock type rattle sound but I cant feel anything through the steering, floor etc that would pinpoint its source. It does it no matter what the vehicle is doing - accelerating, braking, turning and coasting.

Anyone had anything similar and what cause they found?

anti roll bar is hard to check because its always under load so always feels tight only real way to check them is to take the load of the rod and you should feel the excess movement on the ball joints, mine did the same so I replaced both sides and the noise was gone ;)

I will probably replace both sides link rods to be sure (but will get them from somewhere like GSF as Citroens want to charge £39 each!! - reckon I could get two for less than that from GSF)

Our Xsara had a rattle when going over road humps - so my daughter told me. After spending time under the car I couldn't find anything amiss. I cut a piece of foam rubber and wedged it between the fuel pipe and the floor. I don't know whether it has stopped the rattle but I haven't heard any complaints recently.
