Around 80mph and above my car seems to start vibrating, seems to come from the passenger side front. I am pretty sure its not engine vibration, in neutral it revs up nice and smoothly.

Hard to tell if its transmission/drive shaft related.. to me it seemed to come from the front wheel area but again, I couldn't really tell exactly where it was coming from.

Does not sound like a header banging on the floor board but I plan on checking that, but since it only does it at higher speeds I am doubting that being at fault.

Plan is to swap front wheels and see if it follows to the driver side. And then re balance both fronts.

The other thought was maybe the drive shaft? I know that around that speed is where the stock drive shaft will start to make noise if it became un balanced.

Thoughts?
