When in a parking lot, turning either way, my rear end acts as if both tires are tracking at the exact same speed, causing one side to jump/chirp the tires. It acts like a detroit locker or something just for the dragstrip.
What would cause this problem. I heard that it could have the wrong lube in it, with no posi additive, causing the clutches in the rear end not to free up when they are supposed to, allowing the outside wheel to rotate faster than the inside wheel. It is an 88IROC with posi rear.
All help is appreciated....
Thanks, Brandon

 

so your saying is that the rear end doesnt give at all!

and you have the original rear end...


posi aditive is used so that the posi and wont and it dont make a sound and i dont think thats the problem..

what kinda fluid do you have in it?

hey at least it doesnt sound like the rear end has become an open diff...
