I was wondering that. Can you make the diff stronger so that doesnt happen again? I didnt think I would have to with the power/tq I make. Its not like im making 600hp/tq. The car only makes 480/380 or something like that. It seems as though G8s are running 1.4s all day long and not breaking. Do they have built diffs?Originally Posted by TooManyHobbies

What broke? The case, ring gear, and pinion are not readily upgraded. The differential portion itself can be upgraded (TrueTrak or WaveTrac).

I would assume the ring and pinion

So I'm assuming that something happened with my ring and pinion because there are no fluids coming out to say that the cover cracked. If this is the case here is what I'm planning on getting:
3.45 or 3.73 ring and pinion
LPW rear cover
Eaton TrueTrac
BMR Differential Bushings Pro Version
Is there anything else that I would need to replace or get while the diff will be out?

Go 3.45's and change the rear upper control arm bushings if you haven't already.

Ya I know the 3.45s are better at the track, I just liked the 3.70s on the street. We will see. On the suspension, I was going to get these bushings
Rear Cradle
Upper control arm inner
Lower control arm outer
Trailing arms
Either Toe Rods or just the Toe rod bushings
I don't want to spend a ton on suspension. Is that a good list or should I take something out or add anything?

I ended up getting a 3.45 diff and put the Jannetty Posi Unit upgrade in.

Good to hear! Should go 1.4x with some hook!

That's what I'm hoping. You convinced me into getting the 3.45s back. Now hopefully it will stick and not explode again
