i had a whinge coming from what i thought was the rear diff, i changed diffs and the whinge is still there.

What could be causing this noise? it only really starts when i hit about 80kms and stop s when i back off.

could be wheel bearing

[weaves]

what did the rear bearings look like when you removed the axles?

ball bearings often make a whine when they are on there way out.

punch your wife...... that should stop the whingeing

The noise may not be the diff. Have you had the car on a hoist (or stands) to hear the noise from the source. Quite often noises from the transfer/gearbox can sound like they're coming from the back.

When mine did that it turned out to be the hard casing on the pinion shaft.

yeah wheels bearings where my next guess but they didn't look to bad when i pulled axels out,

Mine was vibrating whining like a bitch.

Turned out to be the rear uni on ther tailshaft. She was seized..

[sierra_666]

so best bet would be to take it to a mechanic then i suppose

[tanshi]

if your not able to do bearings your self, yes

the transfer case looks like its been leaking oil might that be part of the problem? should i check fluid?

Um, yes...

That mud hole you ploughed through will eat out seal's in EVERYTHING, checking oil level's should be part of your wash down..

oh you saw that didn't you??? it was quite big wasn't it i thought i was going to need a snatch, i don't have a socket or spanner big enough for the transfer case. otherwise i would of.
