Shimmy

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.

Front toe is adjusted by the use of the inner tie rods.


Shimmy

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

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.
