When i drive the car normal the car doesnt shake at all. But once under full boost the car started to shake really bad. The shaking started right after i was done at the track drag racing. It feels like wheel hop but i'm not even sure.

Could it be the transmission, diff, clutch or just the tires?

any help would be great!

 

is it just when accelerating hard?? because it could be an engine mount or any of the following mounts.. tranny, diff, exhaust.
mine felt like my car shook as if i hit a pot hole even, usually when i changed from drive to reverse or when accelerated hard... just replaced both engine mounts and its now as smooth as ever..

otherwise.. im not sure.

 

idk if this is the same for sc's, but on my Mazda3 i broke both of my CV axles. the car would only shake when the gas was pressed halfway or more. maybe check your CV axles?

 

Good point!!
my cavalier with a 3400v6 broke an axel and it was like driving on a washboard when i gave it any gas..

 

I had the same issued, I messed up in the order of the bolts connecting drive shaft and differential and also driver side wheel bearing was really bad, all fix now no more shaking or fish tailing.

 

when i had the shaking problem it was the mounts. pop the hood and have someone give it gas, if your ish is shaking all around in there it's the mounts most likely.

 

probably engine mounts.

 

I messed up the order of the Drivesahft tot he dif as well shaking started at 28 MPH and then got better, at 80 MPH it was bad and 100 MPH it was bad. I also bought new bolts (6) washers (6) and nuts (6) from Lexus Monday, 52.00 not bad shaking is gone.

 

I didn't understand one word that you said in the last post. How did you fix your shaking issue?
