it's only the passenger side front tire...and it does this only when I am turning to the left, if I let off the gas the vibrating stops...it vibrates so hard it shakes my steering wheel and feels like the tire is about to fall off. any suggestions...tires are all pretty new

 

my first guess would have been the tires werent balanced but since you say theyre new im pretty sure they would have been, i had a similar problem and it turned out to be a worn out control arm ball joint, not saying that is defiently your problem but it would most likely be some ball joint compnent that is startin to go out. i would also check the wheel bearing since i know when their about to go out they have small amount of play and on a front suspension it can wreck havoc. best thing to suggest is just jack up the car on the side you think the issue is on and shake things, if you can feel play by shaking the wheel at 12 and 6 and again at 9 and 3 chances are its a wheel bearing. otherwise if its a suspension compnent you should see visible play in the worn piece. again these are just suggestions as to what may be wrong.

 

Yea, bad balance, &/or bad suspension arms, usually TRE.
