Rear end taking a dump

[Snail Farmer]

I ran to the gas station a little bit ago, and as I was pulling out to come home, the rear end of my Jeep started hopping. Kind of like if the wheels were spinning on a mixed hard/slippery surface. But I didn't see any ice on the road at all. When it happened the first time I immediately took my foot off the gas and disengaged the clutch. As soon as I started to take off again, it happened a second time. After that it drove normally the rest of the way home. I've never had a rear end go out on me before so I really don't know what symptoms to look out for. I'd appreciate if anyone could share their experience.

What diff do you have in it? Is it open or trashlocked?
How long since fluid change ?
Could be a number of things I'd drop the cover and check it out

Chrysler 8.25... 3.73 gears.. open. Last fluid change about 10 months ago with dino oil.. everything looked ok then no metal chunks or anything. Drove to work tonight and it felt fine. I'm stumped but I'll probably pull the cover of when I get a nice day and try to figure out what's going on.

Thanks for the suggestion but I know it's not the clutch slipping. It hasn't happened again since that first time, but something else has happened for the last two days. I stop at the gas station every night before work, and the gas station has a big dip in the entrance. As I'm turning right into the parking lot the Jeep gets off camber, and I hear a loud bang coming from the rear. Not sure if it's related or not though.

I'd open her up and take a good look inside before driving it any more. Your spider gears might be getting ready to let loose. Right now, you might be able to salvage the diff. If something lets loose though, it's likely to take the ring & pinion gears with it. You could also have a broken ring gear tooth, which then means a total rebuild or replacement.

Maybe be something floating around in the rear axle, or could it be the ball joint in the tri-link setup? You said it was a noticeable low spot that you had to pull through. Although it really does sound like the clutches in a trash-lok gone bad.
