Have differential checked to make sure that it is not locking up.
Also have brakes examined for sticking calipers.

 

Thanks, I did not even know these cars HAD a differential. Brakes were what I checked first . I have seen several posts on the differential fluid. Seems to contradict each other. I have always used limited slip 90 weight in my mopars. I see some saying Dexron 3 in for this application. My car owners manual says NOTHING.
