Was getting a noise from front end,just after dealership replaced all bushings (front/rear) as worn.Car has 40k miles. Jaguar dealership said it was the tires. So I put a brand new set of Kuhmo's on my 97 xk8 covertible. I still get same noise from front end somewhere. I think its the bearings or the suspension? Noise is loudest when driving in straight line, really loud between 10 and 60 m.p.h.. faster than this, noise gets kind of muffled. Also if I turn wheel slightly to right or left noise seems to go away, also if I go over a slight hill in road where front end seems to lift a little, noise goes away.Then as weight of front end comes down, noise re-appears. Hope its nothing to do with my steering column?. Can anyone offer suggestions, as dealership keeps saying tires. Its driving me crazy as it wasnt there, when I bought the vehicle,(with same brand tires Kuhmo) or until I had brakes, bushings and full service done. Thanks for anyones help.
