The recirculating ball construction results in a friction free contact between thenut and the worm. When the steering wheel turns to the left, the ball bearings roll between the worm and the nut and work their way upward in the worm groove.

When the ball bearings reach the top of the nut, they enter two ball guides and are directed downward into the worm groove at a lower point. When the steering wheel is turned to the right, the ball bearings circulate in the opposite direction.

Recirculating ball and nut steering gears consist of several parts contained in a steering gear housing. The steering gear shaft is connected to the steering wheel either directly or through some type of flexible joint, and there is a worm gear at the end of the degrees to the worm gear, a ball nut riding on the worm gearand a gear on the cross shaft. It is mainly suitable for high and middle gradelight and heavy duty trucks, jeeps and buses; Suitable for use on GM, Chery, FAW, DFM and Volkswagen vehicles

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.
