Been at this since I bought it a year ago. 94 E320 w/140,000.

I am baffled, I can't seem to pinpoint the issue. When driving a Mercedes, the front end & steering wheel shouldn't shake violently while driving on the freeway.

It's not constant, happens sometimes, front end shakes, steering wheel shakes, doesn't stop if I slow down or accelerate. Doesn't always, sometimes, it's like it doesn't even exist-Intermitent.

Neither myself, or my tech shop can figure it out.

- Brand new tires, put 10K miles on them, no unusal wear.
- Wheels balanced multiple times.
- Recent Alignment - although still not perfect, maybe 7 out of 10
- Wheels don't appear to be bent or have any kinks in them.
- New Steering Dampner
- Motor Mounts seem fine
- Bushings,Idler Arms, Sway Bar, Tie Rods, Ball Joints, struts, springs, all check out, no need to replace.
- Driveshaft checks out, flex discs look great, new center bearing, new trans mount.

The car looks fantastic underneath, despite a few rust spots.

Any suggestions??? Not, driving 100MPH on the freeway so boring...
