You Remember this post you did in 2005? I'm having the same problem with my 2006 G35 Coupe

I had my tires balanced and an alignment DONE....and the "rumbling"/"vibration" is there when i turn the wheel to the right around a curve at 45-50++mph speeds.....I have NO idea what the problem could be....the dealer says my tire may need replacing..i said that's bullsh!t.....taking it in next saturday to get to the bottom of this.....I'll let u know how it turns out....



I have also heard wheel bearing could be a problem....but highly unlikely.....



Like i said alignment didn't fix it, wheel balance didn't fix it....sooooo

do you still have the sub box?
