Well my rear axil bearing finally went on my 1999 STS. I want to do the work myself. I serched the forum for a procedure to replace it but no luck. Does anyone have a procedure or point me in the right direction? Thanks for your time...:confused:

Your best bet is to take out a 1 or 3 year subscription for your car from www.alldatadiy.com. The entire procedure is in their GM service manual section.

The bearings are housed in a capsule - you cannot replace an individual bearing - you replace the entire capsule which is bearings, mounting flange, wheel studs, speed sensor - all one piece. To see what you're replacing, take a look at www.rockauto.com, surf to your car, brake/rear wheel hub, rear wheel bearing assembly. Click on the little picture or the (!) icon for a larger view. Replace both right and left rear capsules at the same time. Use ACDelco/DELPHI. Not a cheap job. Parts are $500 alone, not including brake pads and/or rotor if you need those, too. (special procedure for rear brake pads - caliper reset) Make very sure the brake rotor mounting surface is clean and free of rust when you put it all back together.

I just had my 2003 Cadillac CTS rear end carrier replaced at the Cadillac Dealership in my area. Due to a falty leaky seal, the differential began humming. I just purchased the car recently and it is a good thing that the previous owner had an Extended Warranty which covered the repairs. It's like Submariner409 said, you can't just replace the seal, you have the replace the entire carrier. The Genuine GM carrier is listed at $1,762.00 for my CTS. That is just for the carrier. Then there is the labor charges and gear oil charges. I can tell you that this is not an easy replacement. There are very critical adjustments that have to be set for the proper clearances. If you don't get it right, there goes your carrier. You have to be extremely qualified with a very good understanding of how to set the clearances properly. If you don't have the expertice, I wouldn't attempt doing the repairs. Hope this helps! Good luck, Tommy.

One of us is talking about the rear wheel bearing assembly in a FWD car, the other is replacing the rear axle assembly in a RWD car.

The single bad bearing capsule assembly in the OP's STS can be replaced with $175, a jack, stands, and common hand tools.

Your rear end is considerably more complicated and expensive.
