Ranger 2WD V6-4.0L (2010)
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 (wind, road camber).
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 concern, it is important to understand the difference between wander and poor groove feel.
