The vehicle toe setting affects tire wear and directional stability.
Wander
Wander is the tendency of the vehicle to require frequent, random left and right steering wheel corrections to maintain a straight path down a level road.
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.
Nibble
Sometimes confused with shimmy, nibble is a condition resulting from tire interaction with various road surfaces and observed by the driver as small
rotational oscillations of the steering wheel.
Poor Returnability/Sticky Steering
Poor returnability and sticky steering is used to describe poor return of the steering wheel to center after a turn or steering correction.
Drift/Pull
Pull is a tugging sensation, felt by the hands on the steering wheel, that must be overcome to keep the vehicle going straight.
Drift describes what a vehicle with this condition does with hands off the steering wheel.
A vehicle-related drift/pull, on a flat road, will cause a consistent deviation from the straight-ahead path and require constant steering input in the
opposite direction to counteract the effect.
^
Drift/pull may be induced by conditions external to the vehicle (for example, wind, road crown).
^
A drift or pull condition may exist even if the front alignment is within specifications. To aid in correcting this condition, there are 4 additional
upper control arms available with off-set bushings (2 for LH, 2 for RH). These upper control arms will allow the caster to be adjusted ±0.4
degrees. Refer to Caster Adjustment - Front.
