Well, if the rear fully locked up, then it would stop the rotation of the driveshaft, tranny, and finally the engine. This could stall the engine instantly. Id say pop the rear diff cover and check for broken teeth, backed out bolts or other metal that could be floating around in there.

I take it youve never changed your own gear lube before. No need to remove the PHB or the rear sway bar.
Easiest way is simply a 12 mm combination wrench (i think it was 12mm, maybe not though) You can use a ratchet where it will fit. If you want to get fancy, a ratcheting gear wrench is nice, but my non-angled ones wont fit. Dont forget to drain the fluid into a large enough pail. Youll need 2 quarts of your favorite flavor rear gear lube, and 4 oz of friction modifier (i still use it on my 02). Youll also need a new 10 bolt gasket. Youll need just a little rtv on the gasket. Also a hand operated oil pump will help fill the rear back up, but isnt necessary. With a little work you can wedge the whole quart bottle and squirt it in the fill hole. The fill hole is up at the top on the passengers side of the rear diff housing. a 3/8 ratchet extention fits the 3/8 square recess in the plug.
Look around the drained gear lube and inside the housing for any chunks of metal. Also look for chipped gear teeth, or if you can spot anything wrong with the worm teeth in the torsen differential unit itself. Also look for any place metal could potentially bind like a backed out bolt for instance. Spin the wheels a couple times and have a good look. Youll need a buddy to hold the opposite wheel or theyll just go in opposite directions.

Thanx for the directions guitsboy Though I have a 12 bolt with the aluminum cap so it sticks out little further then the stock one.It looks like I have to remove the phb and the rear sway bar to get the cap off.or at least lossen up the rear sway bar.Thanx for the advice again though will open it up eventually to do a visual.

Oh crap, my mistake. Something about broken rear ends just scream 10 bolt! Well, just incase theres some newb who dosnt know how to change his rear end fluid, now he does! I feel like a real dumbass for assuming you were stock.Sorry again man
One possible idea though, if you put the frame up on jackstands, you can use the jack to raise the axle up and down and this will move the PHB out of the way of some of the bolts. Might save you a couple minutes.... or it might take you longer than just taking the PHB off.... Depends on how fast you wrench.
