Hi, I'm the owner of a 2004 G35 Coupe. For the past few months my car has began to have an intermittent vibration when I take a right turn. Typically at speeds above 40mph+ is when it is noticeable, it will vibrate for a second or two then stop then vibrate again.
Now, I had pretty much thought in my mind that it was a bent wheel. Well today after installing my new set of wheels, it's still there!! Now I'm stumped.. has anyone had a similar experience? Or even any suggestions what it may be? Thank you.

 

I ran over a rock (a big rock) with the passenger front tire while passing someone (going about 80) and it damaged my wheel bearing and it produced a vibration and "droning" sound when turn the wheel to the right. The dealer replaced it under warranty. I could tell it was the wheel bearing because on the lift you could hold the wheel and jiggle it. Only that wheel - the others felt rock solid.

I had to insist it be replaced after the dealer tried to tell me it was just uneven wear of the tires.

Immediately upon replacement, I had my solid coupe back!

 

my friend has an 05 and he had vibrations when turning as well
it ended up being a warped rotor.
