Tony, I have had my MK1 GS300 for nearly 3 months now, and right from the start there was a noise that came from the front of the car when moving - like a rumble at around 30mph to a whine at around 60mph. Took the car back to the dealer (non-Lexus) as I thought it was a worn wheel bearing.
They had the car for the day and reported all the bearings were fine, but the guy admitted after a test drive that the noise was there and suggested it was the o/s front tyre that was the culprit, stating that the Avon ZZ1's (fitted all 'round and newish) were renound for a lot of road noise.
After a couple of days I fitted the spare (with a different brand tyre on), to the front, and sure enough the noise had virtually gone, so put the Avon back on to keep them all the same (noise back).
Now just recently I've noticed the outside edge of the front o/s is wearing quite rapidly - so is the inside edge of the front n/s.
Would this be anything to do with the wheels needing a full geometry set-up... would this cause the excessive road noise and wear?
Any help much appreciated :winky:
Tony.
