Has anyone come across knocking from the steering rack/column if you shake the wheel left to right ?? Also when im driving on the motorway if i hold the steering wheel so that the wheels are straight you can feel play and if i hit a bit off road with a dip on one of the wheels its as if i have no control over the steering in this play spot, all control arms have been replaced and also track rods i thought before it was the control arms that were causing this but it may have been a mixture of the two but the arms were definatly knackerd as the tyres were well worn on the inner edge as the lower rears were totally shot. Any pointers or experiences will be great before i have to start stripping things down. Also what racks/columns are compatible with the TQS.... 1.8T FWD, S4, RS4 ????? Just incase i cant get a TQS one.
