If I were you I would bite the bullet and by a completely new diff and gears and have a reputable shop take care of it.

I wouldn't be surprised if the diff in there now is so damaged it will ever sound correct or work properly. First week in March I'm gettingnew locker and gears installed by a shop that said they will do it right the first time and if something isn't right, they will fix it until it's correct.

Good Luck
