Need help figuring out what's wrong.
So recently baught a 2006 350z grand touring with a lsd diff. I replaced the clutch with a stage 2 and the flywheel with a single disk. I had to make a new slave cylinder arm for the clutch because the oem one was to small. Now I ran into a weird problem. I'll turn off VDC and when I'm in a low gear and get the tires spinning the rear end will kind of shake or made a repeating loud slamming noise and this never happens unless the tires spin. I replaced the diff fluids but it still happens. The only other solution I can think of is on the slave cylinder arm that I made I think I made it a little to long and there no play so could it be something with the clutch? If it's not that the my next step is to get new diff gears which is like $1000! Any ideas? |
Does it do it with VDC on? Does the ECM cut fuel when the slamming starts?.. And explain to me(us) this clutch arm you made. BTW, pics and videos go a long way with posts like this.

Yeah it happens with VDC on but it's prob just trying to stop the rear from spinning in the first place. Idk about the ECM I'm still kind of a beginner at this stuff it's my first "project" car. I used a normal bolt and I cut the top and thread off and rounded the ends so it look pretty identical to the oem one just like a half inch longer. I can't get pics because I'm in school right now. |
Right. I'm just trying to isolate things.. Did it do this before you replaced the clutch(or didn't you try to burn out until after you replaced the clutch..heh)? Does it move in and out of the gears smoothly? Like is it driveable? And it just does it when you burn out?... Idk, it almost sounds like one of your suspension and/or drive train components is loose or worn out in the back.

https://cimg2.ibsrv.net/gimg/my350z....4ef3bb154.jpegYou can’t see it that well because I’m having troubles getting the rubber off but that silver rod is what I made because the single disk I put in made me need more length the engage the clutch |
Hard to tell on my phone, but diff bushing looks dry rotted but no goo...
Take off the slave and see if the fork has alot of slop in it, wondering if you need a new pivot ball and fork, hell i would also replace the slave because cheap and easy |

Sounds like Wheel Hop to me, normal in these cars with Soft or shot bushings on the rear. Best way I stopped wheel hop is to learn how to launch my car properly.

Are we talking about normal driving or are you dumpin the clutch like a moron?
