Quadrasteer

Picture
Quadrasteer operates in three phases.

Negative Phase -- At low speeds, up to 72 kph (45 mph), the rear wheels steer in the opposite direction of the front wheels.

Neutral Phase – At moderate speeds,  about 72 kph (45 mph), the rear wheels remain straight. This is also the failsafe phase in case of system problems.
 
Positive Phase -- At high speeds, above 72 kph (45 mph), the rear wheels turn the same direction as the front wheels. The Quadrasteer control module determines the phasing and amount of rear wheel steering based on the mode switch setting, position of the steering wheel and vehicle speed.

Alignment -- There are provisions for toe adjustment only. Caster and camber are fixed.

Steering Gear Motor – The electric motor is serviceable separate from the steering gear. When the motor is removed, 
the planetary gear reduction set is exposed, so care must be taken to avoid contamination.
