My 2008 vibe w 211,000 miles has had an issue with vibration as of late. This is not vibration that I am used to. Usually, I get vibration through the steering wheel due to a suspension/brake problem, which I have taken care of this is different. The whole car vibrates Especially when I am accelerating. The engine sounds loud almost like there is an exhaust issue, but an exhaust issue would not cause vibration like this. The rearview mirror is vibrated so much that the cars in the mirror look like a blur. It does it the most when I'm driving on the highway at speeds between 60 and 85 mph. The noise goes away completely if I apply brakes and it seems to go away if I am turning or merging. The car drives perfectly and I cannot note any issues with performance. Any suggestions as to what could be causing this vibration?

I was thinking maybe a motor mount, but since it does it most at a certain speed, then maybe something like a CV joint/wheel bearing/tire imbalance, something that resonates at those frequencies

I had a wheel bearing replaced recently and this started soon after. I may take it back in. Its possible the bearing was defective?

It's possible that it's still the bearing itself BUT sounds more to me that one of your CV joints is on its way out. This happened to me on my 2004 Vibe GT a few years ago and started out of nowhere YET that was definitely the problem. It's also possible that your CV joint, which we'll assume was in it's failing stage, took out your bearing and damaged it. Then with only one of potentially two components being changed, the car "seemed" better when in fact BOTH components were not replaced. Look into both of these again and I think you'll find out your problem.
