My rear is making a grinding sound and has a slight pinion seal leak. I am thinking of rebuilding it as I can do this much cheaper than swapping in a 12 bolt or 9 inch. I know everyone will say to do that but really guys, I dont drive the car much and I dont drive it hard, so I will throw a few bucks at this 10 bolt one time. So how can I determine what rear I have and the specs on it so I can order the right parts. There are plenty of budget posis, gears and axles on ebay to make it cost effective. Thanks!
