Recently i been getting a lot of vibration in my car. I brought my car to 4 different shops including Acura and no one can find what it is. I replaced both front tires. Both axles. Got my wheels balanced and a alignment. I checked all the bushing and stuff and everything is good. i do feel like my tranny mounts is lose but when i check them they seem fine. my car is a 04 6spd.. also when im driving thru the gears it shakes a lot. but when i get to a decent steady speed the shaking is not as bad..any ideas would be great.. thanks

 

Is your car lowered?

I experienced a bad vibration when mine was lowered

 

Yes it's lowered but I had it dropped for over a year and it wasn't shaking like thiss

 

Motor mounts?

 

I have the xlr8 mounts

 

Bent wheels?

You already replaced the axles, but that would've been my guess. Can you feel the shaking in the steering wheel?

 

Thats my next check.. Later today imma put the 2 front stock wheels on and see what happens..

 

If it was a bent wheel, the person doing the mounting/balancing would have or should have said something.

I would just check the normals ie: control arm bushings/motor mounts. My car used to vibrate real bad and it turned out to be a warped rotor. You would notice excessive shaking when braking though.

 

Might want to find one of these:
Hunter GSP9700 Wheel vibration Control System solves wheel vibration and tire pull problems that balancers and aligners can't fix

If they've already used one of these, I dunno.

 

have you tried resetting the computer? pull the negative on the battery for a bit.

how about your transmission fluid?

how about some more details about the vibration? this is a common topic on this forum.

 

Same with me bro. It just randomly started happening. Bought all new mounts and still vibrated. I started raising the car (front only) as the car got closer to stock height vibration was reducing, and is pretty much gone. My control arm is pretty much broken right now so I'm back with a bad vibration. Not sure if that'll cause vibrations though.

 

A bad control arm will cause more vibration and pulling during braking.

 

Car doesn't pull during braking or shake.. Starts to shake at about 40 mph..

 

My car been the same height since I got it and it drove smooth as hell..
