You've simply got a bad VC. The VC can fail in two ways, it either fails locked or it fails unlocked. The fluid can permanently lock the plates together or the plates in the VC can 'polish' so that the fluid wont lock them together. Its a good design, but its destined to fail. Just a question of when and how. Most people probably wont realize when they fail 'open.'

The 96+ 249 sends power to the rear until the rear slips (I've read a 10/90 split), then the VC starts locking up to send power to the front wheels. A pre 96 249 sends out a 50/50 split until either the front or rear starts slipping, then the VC starts locking the two together.

I have a 94 zj with a failed 'open' VC. Meaning just the rear or front can spin. I also have a 98 5.9 with a failing 'closed' vc. It doesn't chirp the tires but you can feel it binding at low speeds. Not sure if Im going to spend $800+ to fix the VC's. Most certainly NOT putting in a 242 or 231.

Yea I got it from transpartswarehouse on ebay. I called them up and ordered. Sound like nice guys. Been fine for over two years or 11,000 miles.

I didn't drop the case so I had to make a custom tool because there was no room. Once I got the tail cone off the snap ring pliers are a must. If you drop the case then the pliers will work through the view port to get to the main snap ring. For that snap ring, duck billed snap ring pliers would work best.
Here is my thread on it. http://www.jeepforum.com/forum/f13/r...249-a-1275779/

Well, it ended up that I blew my front differential, lots of broken teeth & sheared bolts. Ordering new Dana 30 parts today.

you know how i know you're gay?


Because you thought of a video game with some guy in a peter pan outfit instead of a kick *** monster movie with Arnold and Jesse Ventura.

I wouldn't bother rebuilding that. D30's are a dime a dozen at the junk yards. It would be cheaper to just go get one, clean it up, and slap it in than to have a shop rebuild the front.
