I have a 2003 mustang gt i was wondering does these cars have a lock or something in the rear end to make both tires spin cause sometimes both of my tires dont spin just the one on the passenger side i was just wondering because if somethings broke i still have a warranty on the car.
its a factory limited slip diff, so when you're going straight it should lock both wheels together... of course its a factory one, so they arent too great.
