Shimmy, as observed by the driver, is large, consistent, rotational oscillations of the steering wheel resulting from large, side-to-side (lateral) tire/wheel

Shimmy is usually experienced near 64 km/h (40 mph), and can begin or be amplified when the tire contacts pot holes or irregularities in the road
surface.
Toe
Wheel Alignment Angles
Front caster and camber are adjusted by replacing the upper arm alignment set shims with washers. This allows for adjustment of the arm in the frame
slot.
