my car only has 45k on it and everything under it looks good,it was in fla for a while..i guess i will look at motor mounts and torque lug nuts...sometimes it feels like it could be like a aero vibration at speed..

I get a little vib at idle in drive,put it in neutral an it goes away...motor mount?

To check your mounts you need to load the motor mounts (i.e. by holding your foot on the brake and pressing the accelerator, have someone watch the mounts while doing so.)

i just re balanced 3 tires out of 4..they went out for some reason..gonna try highway soon to test.

I finally got rid of htis vibration and what took care of it was I removed each engine cradle bolt and drilled out a 3/4" diameter washer to 1" thein installed i unside the rebber mount on the outside and put a impact wrench on it until it could not tighten anymore (All 6 of them) and the vibration is gone at all speeds.
