Poor Groove Feel




Wheel Alignment Angles

The vehicle caster and camber correction requirements are factory-determined. Adjusters are available to correct a caster/camber measurement that does not meet specification. Before changing the production caster/camber adjuster, thoroughly inspect the suspension system to locate worn or damaged components that may have caused the setting to change.

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 "light or low on center".

- In the diagnosis of a steering problem, it is important to understand the difference between wander and poor groove feel.
