I guess I know where the vibrations came from....looks like the bolts on one wheel where not tightend correctly. I drove the car from Princeton to Newark airport and back, 110 miles or so, Stuff really started to shake on the way back, I made it home, but the next day when I backed it out of the garage 12 feet! the front left wheel came off. 2 broken bolts, 2 missing bolts and one stripped bolt.....I was very lucky that this did not happen on the interstate. I ordered a 12x1.5 tap to re thread the holes in the wheel hub, and am picking up 5 new bolts at the local Mercedes dealer tomorrow, I will also try to remove the broken bolts tomorrow, I hope not too much else is damaged.

Stupid,
JK
