Shimmy
Wheel Alignment Angles
The front caster and camber are adjusted by removing the lower arm front and rear bolts and installing adjuster kits to allow the arm to be adjusted in the frame slots. Front toe is adjusted by the use of the front wheel knuckle tie rods. The rear camber is adjusted by removing the upper arm camber set shim or shim pins to allow the arm to be adjusted in the frame slot. The rear toe is adjusted by the use of the rear toe link cam bolt and nut.
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.
