Place the rear axle solidly on jack stands. Loosen the center section cover and drain the oil (if there is any left to drain), then remove the cover. Remove the rear wheels, brake calipers and hanger brackets, and tie them out of the way. (Your 9C1 DOES have rear discs, right?) Remove the differential pinion shaft lock bolt, and allow the shaft to slide downward and out. Push the axles inward far enough to expose the locking clips and remove them. Once the 'C' clips are removed, you can slide the axles out of the axle tubes. Be careful as you near the end so you don't damage the seals with the end of the axle shafts.

Set up a bearing splitter in your press and push the axles out of the outer bearings. Clean the shoulder and seal surface with crocus paper ot a medium stone, and start the new bearing onto the axle. Make sure the shield is on the outboard end of the axle. Press the nearing into place so the inner race contacts the axle shoulder. Repeat the procedure for the other axle, or take the axles to your favorite parts house and have new bearings pressed on. Replace any damaged seals, install the axles, 'C' clips, and differential pinion shaft and lock bolt. Torque the lock bolt to 8-10 ft/lb. Install the cover and new gasket if necessary, and fill the housing with the specified oil and additive (if necessary). Reassemble the brakes and install the wheels. Drive on.

Blue Bowtie,
I can use some guidance???

I tried to replace the axle seals on my 91 Caprice this weekend. It has the smaller limited slip rear end. I removed the wheels, differential cover, pinion shaft lock bolt and tried to slip out the pinion shaft, but it wouldn't come out. I replaced seals years ago and if I remember correctly the pinion shaft slid out with little resistance. I tapped on the shaft and it still wouldn't come out. It had a little movement and slid up and down minimally, but wouldn't come out. I didn't have a puller so I put it all back togehter until I was able to get some advice.

Can I or should I have to use a puller to get the pinion shaft out??? There is only one locking bolt holding it in, right?

Thanks

Blue Bowtie,
i tried to replace my axle seals this weekend, but i wasn't able to get the pinion shaft out. i took out the locking bolt and i could slide the pinion shaft up and down a few millimeteres, but it wouldn't come out. i tapped on it a little and is still wouldn't budge. should i or can i use a puller on the pinion shaft?

Did the lock bolt come out complete? I had one late last year that broke off inside. If that's the case, don't worry - the broken off piece can easily be removed with a screwdriver, awl or other sharp, pointy thing as there is no torque on the bolt shank itself.

Plus, it's always better to start a new thread rather than resurrect one that hasn't been posted in for over a year.

If the bolt is broken try the Differential Extractor Kit. Matco and Fabbri Associates both make one. Worked great on my car.
