Pinion Bushing Repair


The past few weeks I had developed a clunk and some odd squeeks coming from the rear end of the car. This was particularly noticeable when letting out the clutch, like leaving a red light, or when easing on and off the throttle. I did some checking at a buddies shop and found the pinion bushing loose, which as odd enough in and of itslef. However, when I tried to torque it to the specified rating of 48 ft/lbs, I found I still had the issue. After some asking around and research on I found the rear pinion bushing was a common cause, and with that information I went to work.
