Speed Sensitive Steering
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease. As your vehicle speed increases, the
steering effort is also increased to provide a manual like steering feel for
maximum control and enhanced vehicle stability.
The power rack and pinion steering system has a rotary spool valve which
directs hydraulic fluid coming from the power steering pump to one side
or the other side of the rack piston. The integral rack piston is attached to
the rack. The rack piston converts hydraulic pressure to a linear force
which moves the rack left or right. The force is then transmitted through
the inner and outer tie rods to the steering
knuckles, which turn the
wheels
If hydraulic assist is not available, manual control is maintained. However
under these conditions more steering effort
is
required.
