Need help

[nace4g63]

I have a 97 gsx 5speed. With a 6 bolt from a gvr4. When I drive I get a vibration like the tires but if it's cold out it take awhile to start up. I know it's something expanding/relaxing but have no idea what. The front is all new except shocks/springs. I feel it more so under my seat. It drives straight and has fresh alignment. Also has no noise just vibes? Need help

Welcome to the forum!

Vibrations aren't easy to track down. You have to try different circumstances to check to see when they are present, and when they are not. For example: try putting the car in neutral and coasting; try gently applying the brakes; try hard acceleration, etc.

Our vibration in the '99 turned out to be a broken rear motor mount and missing rubber bushings in the front engine support arm, under the radiator.

Report back with some more details on when this is/is not happening, and let us know what you find.

Could be a carrier bearing. I'd start there since it's closer to your seat than anything else.

I was really hoping someone didnt already say that! +1 ^^^

OP: Let us know what you find.

Could be a carrier bearing. Its really easy to check for slop too. Before I replaced mine, they would sometimes let the driveshaft thump around, more so when it was colder outside.

Also when looking at the carrier bearing look at the u-joints, and the rubber bushings that hold the bearings in place. I've had the rot and let the bearing clunk. Good luck!
