Mountaineer 4WD V8-4.6L (2010)
The vehicle toe setting:
-
affects tire wear and directional stability.
-
must be checked after adding aftermarket equipment, such as a snowplow.
Incorrect Thrust Angle (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. For wheel and tire diagnosis, refer to Wheels and Tires.
Poor Returnability/Sticky Steering
Poor returnability and sticky steering is used to describe 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.
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, such as wind or road camber.
