Sorry to bump this thread but it's not that old.
Slight knock from rack when turning the wheel slightly from left to right when stationary(not lock to lock, just a tiny bit) can feel it through the floor, not so much the steering but a little.
I have the same problem as described in some posts above, car changes direction and can go either way when holding the steering wheel straight ahead. Have to hold the wheel quite far to the side on cambered roads, it's very hard to control on a cambered surface snaking all over the place. When coming to a stop the wheel can pull itself very hard(i'm used to a 205 and 106 without power steering!!!!) to either side depending on camber of road!
Had tracking done 4 times in the past few months, keeps knocking itself out. Can't find any play in the system so far, the track rod ends aren't tight but by the same token there's not really play in them but i'm going to replace them. Can't find play in pass side inner track rod joint, will check o/s tomorrow. No visible movement in rack bushes but will probably replace them asap to rule it out.
Car had brand new renault wishbones 5 months ago, they still seem nice and tight and no play in balljoints, no knocking over 99% of bumps.
How can i get to the joints in the column?
