Rear-end Noise. PLEASE HELP!!!

My 97 Grand Cherokee makes a dull, grinding sound whenever I make slow, tight turns. It makes the same sound whether turning right or left. It sounds like it's coming from the rear, outer wheel bearings.

I had them replaced about a month ago and the noise went away--for a while. Now, I hear the noise only after having driven for an hour or more. It's been significantly diminished but still there.

Also, I hear a somewhat loud whirring sound when the vehicle is moving.

When I reported this to the shop, they told me that, since the outer wheel bearings have been recently replaced, they'd have to look at the 'pumpkin'.

They said that they could diagnose the problem only by tearing it apart. That's 6 hours labor which I'd have to pay for if they don't find anything wrong? My extended warranty will pay if there's a problem with the 'pumpkin'.

Does anyone out there have any direct experience with this problem or can offer suggestions as to what the problem might be?

Any feedback will be APPRECIATED.

Sounds like the main axle bearings....do you know if the rear axle is the Dana 44 aluminium version or the regular Dana 35 ?

If it's the 44 then this whirring sound will most likely be the main bearings...common problem...had mine done @ 45k.

Do you have limited slip diff? If so, have you had your diff oil changed? Perhaos they forgot (or didn't think) to put the limited slip additive in with the oil...

Silly me changed my diff oil last weekend and forgot to put it in and can hear it start...I had an IROC that the grease monkey dudes didn't put the additive in and it felt like the whole rear was gonna fall apart (felt 'lumpy') when I turned corners

Mine was doing the same thing at about 50K, the dealer replaced all the bearings in it. Haven't heard anything in the last 20k. Gotta love that P.O.S. D44a.
