well to start off, its wierd when i come out of 1st/2nd it makes a snapping noise?
Sounds like it coming from the Axles

So I'm Driving on the Freeway, And it starts to shake alot and i got a bit scared so i started driving liek 40-50mph, and still it starts to shake alot. Like the Motor or Tranny was going to fall out. Or you think its the axles?

Possibly Looking for upgraded axles, whats a good brand?

BTW, my cars set up is a Ls-Turbo On Stock Axles, I need to upgrade anyways

 

you might want to upgrade your mounts and axles...

driveshaft shop has great axles but expensive

 

check your mounts. especially your rear mount. I had the same problem because my rear motor mount was shot. The rubbery black part was still inside of the metal mount but the rubber wasnt intact with the metal anymore so it let my motor slam around.

 

Sounds like mounts to me as well. I would imagine you have an aftermarket clutch, correct? Stock mounts don't stand a chance against a hard grabbing clutch.

 

Ya exactly. My clutch grabs hard and my mount just took abuse. If i was you i would just go pick up a new rear mount and see if it fixes it. If it does then i would spend the money to pick up an aftermarket mount to ensure that it doesnt happen again. And hey whats the worst that could happen is getting some quality mounts
