ok how can you identify a Limited Slip rear if there is no ID tag on the cover and the cover isnt removed? with the axle jacked up in the air, i can spin the driver wheel and the pass wheel spins the opposite direction, is that not an LS rear? i was told thats its not tonight. reason i ask, is that i can stomp it, and leave pos marks, but if i try to do a burnout im a one wheel wonder, which i thought meant the clutches were going bad. if dude is right then it looks as though i get to spend more money that i had planned. so someone explain this to me please....

thanks
Bart

If it's posi the other tire will spin the same direction when you turn the other. You could just pop the rear cover off too.

yep. also with some limited slip diffs, if only one wheel is in the air (in neutral, brake off), if one spins the airborne tire, it has a decent amount of resistance (posi working as it should).

If it is a 5.0, try a torque brake. If both wheels spin (pending a good limited slip) your good. I believe all 5.0's came standard with LS and the 4 cly did not. I could be wrong though.

It appears to be a B2. Is that the stock rear end? 7.5 or 8.8?

If its a tracloc you will see a big S spring in the middle and you should see the clutch pack. If Its a standard planetary diff you will see nothing but spur gears. Its pretty obvious...you'll know.

Looks like it's an 8.8 with 3.73's and is trac-loc. Could just be the trac-loc needs rebuilt, pretty easy and inexpensive.
