Rear End Issue?

[realspartan]

Hi guys,

I believe I have a problem with my rear diff. When turning from a stop sign or light I feel some binding/slipping from the rear. Other than that the diff works well and locks up when it has to. I changed my diff fluid about 2 years ago with ACDelco synthetic 75W-90 along with a bottle of limited slip additive. What do you think the problem is? Do I add another bottle of additive or do I switch to regular ACDelco 80W-90 diff oil along with a bottle of additive to solve the issue?

Could the issue be the tranmission and/or the TCC solenoid?

Regards,

Switch to the regular GM differential oil and the additive.
