Whining Noise-Diff, Wheel Bearing?
my AU2 (beam axle) has developed a whine noise at 65000k's. Hard to detect from where but driving me nuts even with radio turned up. It mainly occurs at 40-70 k's have put it in third, neutral, still there. Jacked it up from the diff and ran it to 80 k's freewheeling and can't here it maybe it is a wheel bearing or just needs load up on back wheels before it is evident. Someone suggested the 16 inch tyres (Goodyear NCT5) could be the culprit, Maybe I should swap them with a known quiet car to possibly eliminate this scenario - any suggestions or similar experiences would be appreciated.
