Sounds like it's worn out. Different people like different types of LSD (limited slip differential, not the drug). When I have to dig into the rear of my truck, I plan on using a TruTrac, but some don't like it.

You can use your same gears, but you need to buy the correct series carrier (posi unit). If you have lower than 323 you have a 2 series, 323 and higher you have a 3 series. If you are going to replace the posi you should upgrade the gears while you are in there, they won't charge you any extra to do it. 373's will give you a real nice gain without sacrificing too much top end. So if you decide to buy 373 gears, you will want to buy a 3 series carrier to fit them.

Nope the stock posi is an Auburn and it's not rebuildable. Yukon offers a really nice posi that is supposed to be identical to an Eaton but cheaper. I would suggest one of those two. Or an Auburn Pro.

Yes I know all about that, but with my auto car and only 328rwhp I hope it will hold. I just wanted a quick and easy fix, later on if this thing blows apart I will get a 12 bolt. I think it is the best way to go on a Bolton car with a worn auburn; its cheap and easy to install. Only paid $100 plus oil and gasket.
