the problem i have got is this pulling to the left, i have now found that the lower ball joints have about 7mm lift in them each side and the uppers about 2 or 3 i recon that they are contributing to the problem and need replacing. can anyone give me some tips on fitting both the upper and lower ball joints i can't see the point in only doing the lower ones because the mot is next febuary and by then the uppers will fail.
