Incorrect Thrust Angle (Dogtracking)
Incorrect thrust angle (dogtracking) is the condition in which the rear axle is not square to the chassis. Heavily crowned roads can give the illusion of
dogtracking.
Drift/Pull
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.
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 (i.e., wind, road camber).
Nibble
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.
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 Groove Feel
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.
Poor Groove Feel
Poor groove feel is characterized by little or no buildup of turning effort felt in the steering wheel as the wheel is rocked slowly left and right within very
small turns around center or straight-ahead (under 20 degrees of steering wheel turn). Efforts may be said to be "flat on center".
