Can you jack it up and show us if the wheels have any runout? If not then it's your tires. If the wheels wobble need to determine is the wheel or axle is bent.

 

Everything has gone smoothly, they have not fought me on anything. I get the car back Thursday but from what I understand my pinion bearing went bad which also caused another bearing in the rear differential to go bad. They also found metal shavings in the case. They said they rebuilt the backend (I don't know the details yet) and the noise is gone. I just hope nothing happens with the differential because of this since I only have ~20,000 miles remaining on my power train warranty. As far as I know they did not replace any of the gears and I'm not sure if this issue could have damaged or degraded them.

 

If anything else is wrong, or the tech didn't quite set it back up correctly, you will know in short order.
