Anyone experience this? Acts like a driveshaft issue... not wheels/tires out of balance. Car has 54k miles on it so seems early for u joints or flex disc but could be I guess..

where do you feel the vibration, in steering wheel, in seat, in the mirrors, do you hear the vibration ?

In the seat and floor. Can hear it, kind of a low frequency hum.

I'm doing the dealership dance right now for a similar vibration and sound. They've pointed at a ton of stuff like tires and wheels. But the vibration started when I was on the old tires and remained after the new tires . . . Meaning it ain't the damn tires

We talked about it in this thread.
