Noise from rear. Diff? CV joints?
« on: 06 April 2017, 22:26:49 »
02 2.6 Elite with 83k on the clock.
Set off on a dry, flat road and heard a thump from rear near side wheel, thought that the wheel had maybe slipped on some leaves under the tyre. When I now take my foot off the gas there is a constant noise from the rear (I think). Sounds like a quiet pneumatic drill! Obviously related to road speed as it slows down as the car slows. Apply a small amount of throttle and the noise stops so I suspect drive train. Noise still there when I put it in neutral and blip the throttle.
Have had a quick look underneath, nothing obvious, the near side abs ring looks a little oily but no drips from an obvious oil leak.
Will investigate further tomorrow but if anyone has any bright ideas I would be grateful.

Check the diff oil level. I found topping mine up with almost a litre( :o ) made it much quieter.


It might be a knackered wheel bearing. Jack it up and investigate, but even a bad one won't have much play.

Low oil makes a droning sound, was almost fixed on my 5.5 cdx then it got written off.

That too used to bang if you accelerated then braked straight away
