Thank you.
Question: Wouldn't I feel the steering wheel shake if the steering shock or dampener was bad? In addition, wouldn't other faulty steering components also cause steering wheel shake? I don't known these cars very well, pattern of failures. What fixes what. I'm on a learning curve here with working on these MBZ. It sure would be nice to have a known good steering shock to try out.
When the shaking occurs the whole front of the cars shakes hard, but the steering wheel only shakes slightly.
My plan for this weekend is(funny how these weekend projects spill over in the following week, what the heck I'm having fun,sort of):
1. Switch tires front to back and see if the problem moves with the tires.
2. Check and inspect wheel bearings/clamp nuts for loosness.
3. Install "zerk" or grease fitting on pitman arm and lubricate. Somebody previously installed the part and did not lubricate it. It is causing a groaning noise when turning steering. I found this while doing visual inspection and checking front end monday night.
When I hit the lotto

I will starting throwing parts at it, metaphorically speaking of course......
Did not find any thing that would explain the shaking, yet.
By the way, thanks guys for the tips and suggestions, wish I was working in a shop again. Sure would be nice to have a hoist and air.
