Gday
You may have a loose baffle in the muffler.

Front uni joint on rear shaft would cause the noise.
Did they replace the uni's or just balance the shafts?
Cheers

The next thing I would look at is the rear diff preload. Can be a prob if the vehicle has done some heavy towing. Found this out myself after putting in a new front diff, transfer case. Was the preload in the back diff all along. If I loaded the vehicle up, no noise, accelerate hard, no noise, back off hard, no noise, coast between acc and decellerate noisy as hell. Still wasn't leaking at the seal.
Cheers

G'day madabout80's,
More info on where the noise appears to be coming from might help, if you can pinpoint it. When you say worn bearing do you mean wheel bearing?
Have you checked your CV joints for lubrication. Remove the filler plug from the CV and check as per manual with a screwdriver. Add a small amount of oil and see if the noise goes away.
Cheers,
Bill

it sounds like it coming from the gear box area. I work on house hold pumps for a living and it sounds a bit like pump bearing when its on its way out but a bit more nasty sounding

Yes ,I have had this problem.
This is going to sound REALLY stupid, but disconnect your speedo cable and go for a drive. I know people that have fixed wheel bearings, unijoints and rebuilt the gearbox and transfer case, before finding out it was the speedo cable. Having heard the noise myself on one vehicle I could not believe that this noise could be coming from a cable. A couple of mechanic friends of mine said that they have rebuilt gearboxs on the owners request only to find a hell of a noise coming from the speedo cable when they took it on a test drive.
Good luck, Tony.

could be one of the diffs on its way out. they can send the noise along the drive shafts, or it could be the centre diff.

Mate had a similar issue where one of the spacer blocks supporting the exhaust fell off. He thought it was a uni joint also.
Hope this helps

It's not a vacuum leak is it, this sometimes can make a squealing type noise when vacuum is high like going down a
hill or on flat ground.
Just a thought , I may be on the wrong track.

Mine had an annoying vibration/noise that came in at around 100k's especially when accelerating.
Had it checked out a few times but no one could find the source. Unfortunately it turned out to be the bolt holding the harmonic balancer on had worked loose. It ended up chewing out the key way on the crank and was a costly repair.
Might not be your problem but another thing you could check.

This is a common problem particularly after a timing belt has been replaced.
However we are all just guessing unless you can supply more info as to the location of the noise.
Gearbox rattle is common on many 4by4 due to the size of the gears. My 80 makes a serious rattling noise if you are too low in the RPM for the gear. That is normal and one of the reasons manufacturers have fitted these bloody Mas damper flywheels to modern vehicles. Problem is they cause more problems that the fix.
Cheers
Wayne

I didi have a vibration issue that was the cause of noise at certain speeds. turns out it was the tires caused by the way they were wearing... Good luck
