Title: Knocking sound when going slow, and going over bumps.
Post by: ryanbrook on 26 September 2012, 14:04

I have a knocking sound when going slow (pulling away slowly), and when going over uneven road surfaces. Any ideas what it could be?

Lower arm bushes maybe? Jack it up and get the wheels off, then use a pry bar to search for excess play.

Mine did that required new rear axle bushes, new struts, new wishbones, and mounts all round basically.

Drive shafts? Mine knocks round corners a little. But I know I need top mounts doing.

mine has done this for a year now. Obviously I dont know if its the same noise as yours, but I cant find anything wrong. Passed its MOT no probs too. It feels low down at the front, I think it might be the calipers moving around.  :undecided:

Surely if the calipars are moving that can't be good?

calipers can move when the brakes arent applied.
