Ok Today I was just driving up and down my driveway just for fun i guess, considering i have no plates yet (gettin them tomorrow!!). Ok I backed up to like the end then floored and peeled out a little bit then when I went to look there was only 1 skid mark. Big Thick 9.5 inch mark on one side and nothing on the other side. My driveway it tilted to one side the higher side which was the right tire and thats the tire that made the mark, the lower side was with the tire that didnt make the mark. So could that be a factor in my one wheel peel.

So what do you think, is my diff done?
