Wobble left to right...that is a good explanation of what I am getting. It almost seems like the wheel is vibrating from the shudder in the vehicles, as opposed to the typical steering wheel shake when your tires need alignment.

It also seems to come and go. Not with road conditions...but with time. Gets worse the longer I drive, but doesn't ALWAYS get worse. I drive 95% of my driving on the same roads so I've got a pretty good feel for where the bumpy spots are. The shuddder or virbration issue doesn't seem to correspond to the bad areas in the road...

When the vehicle was in the shop I asked them to look at the brakes. They said I had some rust build up on the rotos and that might be causing the squeek I that I hear. They said that I could try to make a few hard stops and see if that "clears off the rotors" because it didn't seem very deep. Perhaps they did this and let the vehicle sit with hot rotors and they warped?
