09 open diff rear destroyed

1loud370z · 07-13-2016, 10:59 AM

As the title says my open diff in my 09 base is shot. I have z1 building me a complete bolt in diff with 4.08 gears and a wavetrac rear and I ordered their z1 intake while I was at it. I should have everything installed Friday. I'll post a review.

Interested in hearing about the wavetrac

What were you doing when it broke and how many miles?

1loud370z · 07-14-2016, 07:51 AM

2009 base non sport with 30k. I'm running 305 bridgestone re11 in the rear so I have lots of grip, which I just don't think my stock rear could handle. I actually launched the car pretty hard against a friends srt8 challenger from a dig. I killed him out of the whole but unfortunately I also killed my rear haha.

Pretty hard to break an open diff.

Well I have successfully broken mine. It was obviously the weakest link in my drivetrain and it decided to let go. My new wavetrac w 4.08 gears are being overnighted today, and I'll install everything tomorrow.

i have a base model as well and swap out my diff for 4.08 w/ quaife LSD and i must say well worth the mod. going on now for almost a yr with no issues. keep your old gears in case u decided to go turbo down the road.

The Definitive Differential Thread there are some user reviews on it on this thread

Got the z1 intake and the new rear in the car this afternoon. Took about 4 hours for everything. What a night and day difference in acceleration and the way the power is put down. I gave z1 a call 9 am wed. and i had my new rear delivered around noon today. Thank god for overnight shipping. Huge shout out and thanks to z1 motorsports for making it happen in such a short notice

I don't think the stock differential can break just by launching ours cars (I have a sport so I don't know if the LSD differential is the same)

My differential was an open diff as I have the base model non sport and no srm. We were able to spin my drive shaft almost over half a turn before anything else would grab. I didn't pull the old cover off yet that'll be this weekend.

It will be interesting to see what failed. Can't see it failing without a clutch upgrade. Anything done to the diff before? How about the diff bushings?

1loud370z · 07-21-2016, 05:56 AM

The center diff bushing in the rear subframe had a little tear but was still filled with fluid. The two on the sides were good. After removal of the diff. cover I noticed I busted teeth off of both pinion side gears and off the gears directly connected to them. Looks like a stock open diff. On the inside.
