Morning All, I have been a member here for a while and found lots of good advise, so thanks for that.

This current issue is proving rather difficult to resolve.

For a long time now I have had a noise, which sounds like a worn bearing chnages with speed, no difference on over run, coming from my read diff.

So far I have had it to 3 different garages all of which I trust and everone is saying the noise is coming from the diff, not wheel bearings or prop bearing etc.

I removed the diff and Haldex unit, and sent to a very experiance mechanic( which I trust) who has repaired several diff's in the past but has not been inside one of these. After stripping the diff, the only problem he could find was one bearing was slightly ruff, which was replaced.

I then put the diff and haldex unit back into the car, and it has made no difference whatsoever!

Any know what could be causing this noise?

Thanks in advance for any info.
