[QUOTE="specizripn, post: 15275677, member: 130913"] Background: So long story short the other day I got really bad wheel hop and made a nice sized hole in my rear diff cover. It was late at night so I drove the car (without gear oil :bash:) around 7 minutes to a friends house where I left the car overnight. The next day I had the car towed to my house, and after inspection the half shafts and suspension appear to be fine. Anyway my gears were whining before I blew the diff cover, and after driving several miles without gear fluid I'm sure my bearings, differential, and ring and pinion gears aren't too happy with me. So I have decided to overhaul the rear end. I'm going to buy a new Traction LOK because it isn't much more expensive than rebuilding my factory differential, so I may as well start from scratch. I will be getting one of the install kits with all new bearings, shims and seals from Ford Racing. Also I wan't to eventually upgrade to a Kenne Bell so I have decided to switch to 3.27 gears while I'm redoing the rear end. I will also be swapping out my bushings when I get the time, because I can't break anything else with wheel hop. Question: So after searching and scrolling through thread after thread I have found a lot of people on this forum advise against the Ford Racing/Motive ring and pinion gears.
