The steering linkage is made of interconnected parts which move every time the steering wheel is turned. The rotating movement of the steering column activates mechanisms inside the steering box. Tie rod ends, which join the key parts, passon the steering wheel's motion no matter what the angle of the linkage or the vibration from the road. In a pitman arm steering setup, the movement inside the steeringbox causes the Pitman shaft and arm to rotate, applying leverage to therelay rod, which passes the movement to the tie rods. The steering arms pick upthe motion from the tie rods and cause the steering knuckles to turn the wheels.
The steering linkages need regular maintenance for safe operation, such as lubrication and inspection. Faulty steering links can cause tire wear at the least, and complete loss of control of the vehicle at worst. "Popping" noises (when turning the wheels) usually indicate worn out steering linkages.
The integral steering gear uses a recirculating ball gearbox along with a pitman arm to steer the vehicle to the left or right.
Common signs of wear include sloppy steering feel, and reduced steering responsiveness
An integral power steering gear having a primary or input shaft, a secondary shaft, a valve mechanism and a power piston, all mounted on a single housing in axial alignment with one another. The power piston is movable axially relative to the valve mechanism and has a hollow formed therein which receives at least a portion of the valve mechanism depending upon the relative axial position of the power piston and the valve mechanism. The valve mechanism is located in one of the two pressure chambers located on the opposite sides of the power piston.
