Aight, went had the tires aligned, rotated, and diffs re lubbed. Now since i got it back it jerks a lil when i turn it hard, Did it when we first bought it. I remember my dad put some additive in it to stop this from happening. And the shop says that everythings fine with it. So im sure it just needs this additive, however hes dead so i cant ask him what he used so, ne ideas anyone?

 

Talking about the rear??? I assume you mean the friction modifier....?? Get a couple of bottles from a dealer...put one in and see how it is.

Did you use synthetic in the rear diff?? If you went with synthetic...you may not need the FM...

 

Remember that after you change the lube and friction modifier in a Limited Slip diff, go to a empty parking lot or something and drive several figure 8's. That will work the lube and modifier into the clutches.
