2009 Prius shaking while driving grinding noise

maybe a bad cv joint or wheel bearing? how many miles on her?

 

So is the shaking related to when the car moves? Or is the shaking related to when the gas engine is on?

 

Hey man, just chased this same problem for several months in my 2007 Prius. Jack up both of the front wheels, start the car and put it in drive, both wheels should turn. My car felt like the passenger wheel was about to fall off. It turned out to be the drivers side CV axle hat failed and one of the bearings had come completely off (there are 3). This caused it to vibrate at about 50mph when accelerating or decelerating. There was a sweet spot where there was no vibration. I included a couple of pictures the first is missing 2 bearings, the second is the way it is supposed to look. The part of the axle that held the c clip on broke completely off.

 

If you have already gotten your car inspected by the local shop, could you please post what the local shop told you the issue was? Thank you.
