I need help I just bought a 2005 g35 coupe 6 speed I had it for literally 2 days and when I press the gas the stick shakes and that causes the whole car to shake I've brought it to many mechanics and none of them know for sure one told me to have a few thousand cause they have to see what it is inside the tranny.. I'd rather not do that... Anything helps thanks in advance!!

 

Here is A video

 

drive-shaft center bearing?

The one that holds the drive-shaft to the body of the car maybe?

 

I agree with Joker put your car up on stands and grab the driveshaft see if it flops around or has any play. I just replaced a driveshaft on my Audi A4 because it would flop around like crazy and cause all kinds of problems.

 

I can't see the video on my tablet, but that sounds like what happened to my car. My flywheel was shot after a drift event. The oem dual mass fly wheel had way to much play in it causing it to shake and vibrate.

 

I was told it was the fly wheel but someone told me that these cars are different and that I'm going to pay over 1k just to do the fly wheel ( I have owned many manual cars and I've never paid no where near that much for a full clutch job)

 

Every shop will have a different labor rate, you should call a few shops to get a quote. I paid $775 for my Jwt clutch and flywheel kit, and did the Installation myself. If you're going to have the transmission out to replace the flywheel might as well replace the clutch and throw out bearing.

 

Okay thank you. I guess I have to get a new one I hope It works

 

Here's another video

 

stop driving it and posting videos.
Get under the car and check the driveline bearing. If it falls apart you'll damage your transmission and entire bottom of the car.
