Memory Steer Description

Memory steer is when the vehicle wants to lead or pull in the direction the driver previously turned the vehicle. Additionally, after turning in the
opposite direction, the vehicle will want to lead or pull in that direction.

Wander Description

Wander is the undesired drifting or deviation of a vehicle to either side from a straight path with hand pressure on the steering wheel. Wander is a
symptom of the vehicle's sensitivity to external disturbances, such as road crown and crosswind, and accentuated by poor on-center steering feel.

Scrub Radius Description

Ideally, the scrub radius is as small as possible. Normally, the SAI angle and the centerline of the tire and the wheel intersect below the road surface,
causing a positive scrub radius. With struts, the SAI angle is much larger than the long arm/short arm type of suspension. This allows the SAI angle to
intersect the camber angle above the road surface, forming a negative scrub radius. The smaller the scrub radius, the better the directional stability.
Installing aftermarket wheels that have additional offset will dramatically increase the scrub radius. The newly installed wheels may cause the
centerline of the tires to move further away from the spindle. This will increase the scrub radius.

A large amount of scrub radius can cause severe shimmy after hitting a bump. Four-wheel drive vehicles with large tires use a steering damper to
compensate for an increased scrub radius. Scrub radius is not directly measurable by the conventional methods. Scrub radius is projected
geometrically by engineers during the design phase of the suspension.
