Hi Ian, Well where do I begin. The car began making a very faint noise a few months ago but drove normal. Just before the new year I put new rear tyres on and this garage I used did the tracking, after that the car was mess. The noise was quite loud, the suspension sensor warning light came on and i got like a crunching sound but quite regular now. If I mounted my drive which is slightly raised it was very loud. The car also started tram lining so took it back, had no joy and decided to get a full geometry check done. The chap who did the check, Drury Lane was excellent but said to me that the back passenger rear has a fair bit of play on the wheel and he it's is the bearing for definite and that is why its making that noise. Also the suspension warning appears instantly on the dash now because the sensor is picking up the play in that wheel, sounds reasonable enough. So essentially had a job done, made car worse but in retrospect made it right, had full geometry done and found this issue but the guy reconks it is quite bad and that I shouldn't drive the car until I have it fixed.
