Recently I've been getting a wobble on my steering at about seventy, so by following all advice given in previous post by others, I've checked all main steering/suspension parts. The wishbones and droplinks have been changed and there wasn't any noticeable play in the wheelbearings, but still it wobbles. After the changes, with the car on its wheels on the ground if you rock the steering back and forth theres a slight knocking from the front passenger side, could this be a wheelbearing, the trackrods seem to be OK.
Also if this is the case that its a wheelbearing, are they the same as the astra in that you have to change the hub.
These wheels have been balanced three times by a trusted and very experienced tyre fitter, two month old tyre and no buckles.
Please help as I've about had enough, sorry about the essay
Meant to say its a zaf gsi
