Starts at 40 and buy 50MPH during acceleration it'* really bad and as soon as I let off the gas it stops. Nothing happens when I apply the brakes or coasting. 166K Any ideas?

Have you checked the motor mounts?

Check for play in the CV joints.

2 new cv joints and a wheel bearing. I trust this shop but... They are convinced it went in the ditch hard. If it did it was well over a year ago when my daughter dove it for a few weeks and seems like the underside would be all messed up and tire wear is perfect. This problem just started started a few weeks ago. He said the wheel bearing was broke in half, it was not making any noise or grinding however it is the OEM one. It has always had a little clunk in the steering when moving back and forth sense we bought it with 48K and that is gone. What do you think?

Did they check the front end (tie rod ends, balljoints, control arm bushings) when they replaced the hub bearing?
