the clutches in ur rearend are most likely worn and it is not engaging the other wheel.

and the M means u have 2.73's or 2.79's i forget either way.. its a crappy highway gear ratio.

Yeah, it's a 40 dollar kit. Just have them do it at the same time. Then say goodbye to one wheel wonders...or the one tire fire.
