Thread: Rear Diff

  1. #1

    Default Rear Diff

    So my rear diff took a dump on me sunday night, i was on a steep hill and it was raining. It then broke traction when i was trying to pull into a parking place. Right then a loud thud and lunge forward as i was turning right. Has this happened to anyone else? I had it replaced today and it ran me $1100

    Im asking because I want to know if anyone has upgraded thier rear diff

    Welcome aboard Chris. What exactly broke? Is it a Gov Lock posi or do you have an open diff?

    Short answer: Yes, many people have upgraded their rear diff. When my 10 bolt G80 blew up, I replaced it with an ARB differential.

    You don't say what it is you're driving, so, as Jimmiee asked, what do you have now? What sort of upgrade were you thinking of?
