I have a 2008 GX470 with a vibration in the floor on the drivers side that annoys the h*** out of me. It isn't related to vehicle speed or engine speed although the dealer blames it on the tires which I replaced anyway. I wouldn't even call it a vibration, it is more of a resonance. It feels like a thousand bees in a plastic bag trying to get out. I can feel it through the gas pedal, brake pedal and floor board. It gets better and worse for no apparent reason.
I don't know if that makes sense but I am about ready to sell the thing if I can't figure it out. Has anyone else had a problem like this and if so what was the cause?
