Tom's Differentials has rebuild kits. Buy a GM overhaul manual will show you how. Helps to have a pair of axles you can use to rotate spiders back into case after installing new clutch plates. Springs can be a *****. I compressed mine and wired them together, then inseted into the diff, cut the wire and worked it out with pliers.

Really don't want to spend $20 on that overhaul manual, huh? Trust me, it is the BEST repair book you'll ever buy.

Shows how to R&R differentials, install ring and pinions, rebuild PS pumps, AC compressors, transmissions, etc. All of the stuff the crappy aftermarket books don't tell you.

Other than that, just take it apart and put it back together with new parts. That's how I rebuilt mine circa 1990.
