intermittent rear vibration at 60mph

[PK]

The rear wheel bearings are normally called the "rear axle bearings".
They are installed on the outer end of the axle.
To replace, remove wheel, brake caliper, disc etc.
Pull axle out and then you need at least a 5 ton press to press the old bearing off, and the new one on.

But from the description it sounds like greasing the driveshaft will fix the problem. Remember there are 3 nipples, and all need to be greased.
2 x u joints and the splined yoke at the gearbox end of the shaft.

Rear axle bearing noise is very easy to distinguish from other noises.
It makes a "whup-----whup------whup" sound that corresponds to one turn of the wheel.

i dunno i had the work done when i had just bought it and the guy (only mechanic trust) said it needed a new bearing (he pointed to the drivers side rear wheel) and that's why it was loud - i cannot find the receipt but i think it was about $450 parts and labor for the bearing, all the rotors to be turned,all new front pads, and one new front caliper - sorry prob doesnt help much if i see him soon ill ask

Thanks Evil

I like your knowledge. Tonite I checked rear diff fluid, it smells just fine and is up to level, and it has a great oily feel, looks like new actually. So I greased up my drive shaft at all 3 points and will check it out tomoro. Thanks PK and everyone else who took the time to respond.

Follow up report--Greasing the driveshaft has fixed the odd vibration. I cant believe it. However, there is still a high pitched howl from the rear at the speeds stated earlier. Thanks to all who responded and I hope this will help someone else in the future.
