Angry 9 bolt is toast

so after 103,700 miles the 9 bolts decided it has had enough and now locks up while im taking turns. IM guessing i took a tooth off a spider gear. Does anyone know where i might be able to find a set? cause everyone i talk to has no idea what this rear end is.

Re: 9 bolt is toast

the nine bolt uses a cone style limited slip diff. there is a great article on tgo about rebuliding the carrier and machining it so the diff works properly again.

Re: 9 bolt is toast

I just had all of my axle bearings and wheel bearings replaced. They were in pretty bad shape. Sometimes I really hate owning a second hand car because of how previous owners treat them. It wasn't cheap either...
