my buddies 96 accord four door vibrates between 2k and 2.5k. and it gets worse during right hand turns and really occurs after the car has been warmed up.
its a non vtec auto. i got under the car and couldnt see or feel anything vibrating but its a pretty loud, high frequency noise.

any help is greatly appreciated.

 

Accelerating? Braking? Coasting? Stopped?

Motor mounts?
Tires?
Alignment?
Axles?

Bunch of possibilities. Right hand turns and after the car has reached temperature seems like an odd combination. And are probably just coincidental.

 

I'm betting on bad mounts.

 

idk if it could be anything like the alignment. i know alignment shakes. this is a body rattle, as its far too high frequency for tire/alignments.

its coming from the rear driverside passenger floor boards. during coasting only.

 

Possible bad wheel bearing.

 

Or bad control arm bushings.
