Xray T2'009: Severe Wheel Chatter or Shaking when Turning

Xray T2'009: Severe Wheel Chatter or Shaking when Turning, sounds very rough.

I haven't even tried the car on the ground yet, just on stand.

I get severe wheel chatter when combining some throttle and turning, it gets worse the further I turn and the more the throttle.

This only happens with front wheels on.

The wheels do not seem to be touching anywhere, even though they will touch with no shim, I'm using a 1mm steel washer, but the nut is tight, so no movement.

I've tried it with the front wheels off and no chatter, no noise just smooth operation.

I've tried shimming the wheels even more than 1mm, tried 2mm, 3mm still the same.
