Dogtracking
DOGTRACKING
Dogtracking is the condition in which the rear axle is not square to the chassis. Heavily crowned roads can give the illusion of dogtracking.
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 described the poor return of the steering wheel to center after a turn or the steering correction is
completed.
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.
