I have a manual 2002 Z24. I installed a Spec II clutch, Fidanza flywheel, and Phantom Grip along with every poly bushing you can put in our cars this past week. Now I'm having problems. My car shudders fairly violently while traveling down the road and turning right. Only bad when turning right. The faster I'm going, the worse it gets. I was thinking it was an axle not engaged into the tranny but I pulled them out of the tranny and put them back in and no change. I'm wondering if this could be attributed to the clutch or phantom grip. I jacked my car up and took the wheels off to visualize what was happening. In this situation, the whole car shakes with wheels pointed directly forward. The driver side axle shakes more violently than the passenger side (or so it appears with the passenger side being longer and more difficult to determine). The transmission shakes horribly during this situation.

This is aggravating because I took my time on the install to be sure I got everything right. All the right torque specs and everything. The only thing I was unsure of was the install of the axles, because they are a pain in the ass and difficult to tell when they're fully in.

Thanks for any help you can give in advance.

Also, If you're going to leave a one sentence whitty remark that has nothing to do with my post, please pass. Nobody cares how much of a dick you can be.

So it shudders when engaged?

If your going down the road and disengage the transmission, does it shudder still?

This is a quick test to eliminate a lot of possible causes

Yes, the car still shudders when I disengage the tranny while rolling. However, the car runs great in neutral at a stand still.

Thanks for your insight guys, but the problem is exactly what my original guess was. One for the records: If your car shakes like a horribly misaligned wheel after tranny work, then it's probably a blown cv joint. It was infact an axle. These axles are supposed to be indestructable. We'll see if I can get them replaced for free with the lifetime warantee I have on them.

Thanks again.
