I have noticed latley that my rear diff will "lock" up when making turns and it sounds and feels like I am draggin the outside rear tire. This mainly happens after a fast start. I just changed the diff fluid 2 weeks ago nad inspected the oild fluid and didnt find any shavings. This is an itermittent problem. Any ideas? It is the G80 rear end too.
 
Thanks, Scott

Short answer abridged from Second Edition Service Manual for '98 Chev/GMC...
It appears that the center support bearing is a press off/press on arrangement. You do not want to use a hammer.
 
Support everything to prevent excessive bending of joints.
Make reference marks to put things back in the same orientation for balance.
Start by removing the rear u-joint from the differential and tape the joint to keep the caps from falling off and loosing the needle bearings.
Next remove the center support bearing bolts and remove the assembly.
Install in reverse order.
KEEP EVERYTHING CLEAN and re-clean before assembly.
A longer answer involves knowing if it is a two piece or three piece assembly, if it is a Dana or American Axle propeller shaft, and how much it will cost to have it towed to a repair shop if you loose something.
 
The last center support bearing I replaced was on a '70 BMW 2002. I've slept a few times since then. No pressing. Just a stubborn circlip and rubber flex joints that required compression to align bolts on re-assembly.
 
Good luck.
