A bit of a dilemma. Car has only 85,000 and is clean, new tires, no play in the wheels, vibrates around 52-65k. Checked balance they balanced them but said 2 of the wheels are maybe bent.I doubted their machine so I put another set of wheels from another c I have, same thing. It almost feels like the cabin vibration you would feel when you have a bad transmission mount. But when you put it in gear while parked you barely get any vibration, so I removed the mount and it's in good shape, same for the center support bearing, anything you suggest I check that I have not thought of? It's an RWD, no AWD.

Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. I would check the tie rod ends I have seen them wear and cause a vibration at speed, also this guide can help as well:

Here is how to replace the tie rod ends in case you need it:

Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

You won't be able to hear it on video, it's an inside vibration felt while driving unfortunately. Tie rods and all suspension parts are solid.

I would check the driveshaft to see if the rubber donuts on the drive shaft are okay.
