theres a couple ways to tell...do a burnout and see if you have a one wheel or two wheel spin...or jack it up and spin one wheel..if the other spins then yes you have a tlok..I purchased a 2000 V6 vert, that the previous owner had done some work to. So far I have figured out that he did suspension related work, such as Shocks, spring, ect. Now to my question about the diff:
I see a lot of posts talking about the stock diffs on Mustangs saying that only the right rear wheel has power, and that the left wheel will spin freely. When I make sharp right turns, like into a parking space, my left tire skweals. Does that mean that he replaced the diff to, and if so, what kind of differential would cause that to happen?
