Shuddering while making u-turns...Need diagnosis

[ps2cho]

A sort of continuation from the tire thread...

Basically my 300TE yesterday made a really horrible shuddering that was felt in the tires. Almost as if it was dragging on the asphalt when I was making a U-Turn...

I got under the car today and found this:
I don't know if my issue has forced the washer out, or if it was incorrectly installed when I got the car aligned a few years ago.



Does this indicate anything?
The tie rods, drag link and LCA's are new Lemfoerder within last 25k...

Any ideas what could be causing this? I feel like after considering the tires, it seems too much of a shudder to be a simple tire issue...
