CONDITION:

On a smooth, flat road, the vehicle may exhibit a type of lead or pull condition. This would be directly following the completion of a turning maneuver.

This condition is always noted as being in the same direction as the last turning maneuver.

The upper strut mounting bearing may be sticking or binding which may cause a preload on the strut. This preload may cause the vehicle to move in the last direction turned, thus causing "Memory Steer".
