Mustang V8-4.6L (2009)
Incorrect thrust angle (also known as 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
Camber and toe are adjustable on the front suspension systems. Front camber is adjusted through the use of a service repair kit (3C396). Caster is preset
at the factory and should only be adjusted, through the use of a service repair kit (3C396), after all other possible sources have been inspected and
corrected as necessary. Front toe is adjusted by the use of the front wheel spindle tie rod.
Drift/Pull
Pull is a tugging sensation, felt in 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.
-
Drift/pull may be induced by conditions external to the vehicle (that is, wind, road camber).
Nibble
Wheel Alignment Angles
Camber and toe are adjustable on the front suspension systems. Front camber is adjusted through the use of a service repair kit (3C396). Caster is preset
at the factory and should only be adjusted, through the use of a service repair kit (3C396), after all other possible sources have been inspected and
corrected as necessary. Front toe is adjusted by the use of the front wheel spindle tie rod.
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
Camber and toe are adjustable on the front suspension systems. Front camber is adjusted through the use of a service repair kit (3C396). Caster is preset
at the factory and should only be adjusted, through the use of a service repair kit (3C396), after all other possible sources have been inspected and
corrected as necessary. Front toe is adjusted by the use of the front wheel spindle tie rod.
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."
-
Under 20 degrees of turn, most of the turning effort that builds up comes from the mesh of gear teeth in the steering gear. In this range, the steering
wheel is not yet turned enough to feel the effort from the self-aligning forces at the road wheel or tire patch.
-
In the diagnosis of a handling problem, it is important to understand the difference between wander and poor groove feel.
