Just bought a 13 plate freelander 2. When I turn and get anywhere near full lock I get a serious juddering from the rear. This stops as soon as I straighten up. Took if back and it was test driven by a mechanic and was told no fault codes were showing, there were no probs from a visual inspection and that they all do it and it was probably worse because the front tyres are new and the rear ones part worn !!!! Can anyone please advise?
