Nibble 

Sometimes confused with shimmy, nibble is a condition resulting from tire interaction with various road surfaces and experienced by the driver as
small rotational oscillations of the steering wheel.

Poor Returnability/Sticky Steering 

Poor returnability and sticky steering are used to describe the poor return of the steering wheel to center after a turn or steering correction.

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 the hands off the steering wheel.
^

A vehicle-related drift/pull on a flat road causes a consistent deviation from the straight-ahead path and requires 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 crown).

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). Effort 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 the 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 driveability problem, it is important to understand the difference between wander and poor groove feel.
