check with local transmission shops about a rebuild. otherwise these guys are reasonable and did a great job on mine. You just send your third member to them and they rebuild and send back..

Most common problem with the 8" & 9" is pinion bearing failure. Much of that is caused by corrosion damage when the cars sit for an extended time due to moisture.

Pretty much every part of an 8" or 9" rear is available in the aftermarket.

Being that you're in SoCal, I can't imagine it being too tough to find a shop that can handle the 8" rebuild. If you'd rather have a plug-n-play solution, there's a guy "TJ" on eBay that sells complete reman 8" rears with new gears and a trac loc. Gear ratios are your choice. Lot of good feedback about him on the VMF.

My wife says the same thing about my rear end, getting loose and making lots of noises.

The hardest part of rebuilding a differential is removing and replacing the bearings, a press is needed. Other than that, they are pretty straightforward, especially 8" and 9". A good dial indicator and a dial or beam type inch-pound torque wrench are also needed. A large foot-pound torque wrench is also needed for the pinion nut. A fixture to hold them while wrenching on them is nice, but not necessary. Pulling the third member will make you wish you had spent more time on the weight bench, that sucker is heavy. Good quality bearings are a must.

+1 on that. It was damn near as bad as doing the transmission on my back.

I was wondering who was going to key in on that.  Haha

I was surprised he didn't beat me to it.
