The lower telescoping shaft is not the same for right hand drive and left hand drive vehicles, so it is important to install the correct shaft to maintain steering angle. The upper end of the shaft is attached to the intermediate shaft, and the lower end is attached to the hydraulic distributor gear on the steering mechanism. There is only one way to arrange these connections, which serves to ensure the correct position of the steering wheel in relation to the steering gear. The shaft consists of two shafts: pin and socket, having a telescopic connection. The pin shaft is capable of axial movement of 77 mm (3.03 inches) inside the socket shaft in the event of a frontal collision to reduce frontal penetration. The sliding fit also allows for dynamic shifting of the chassis relative to the body when driving in severe off-road conditions. A plastic bushing is installed on the pin shaft. It is used only when assembling the car, and after installing the shaft on the car is not used.
The female shaft is a tube with a triangular section and a double D-shaped hole at the upper end for attaching the intermediate shaft. The recess in the wall of the tube ensures the correct relative position of the intermediate shaft and the lower telescopic shaft. A union nut, riveted on one side of the hole at the end of the double-D shaft, serves to fasten the bolt holding the intermediate shaft. A dust seal is installed around the end of the socket shaft to prevent dirt and moisture from entering the sliding joint. A heat shield is also installed, which reflects excess heat from the exhaust manifold.
The pin shaft is a tube with a triangular section, riveted at the lower end in the form of a flange. Attached to its upper end are twisted spring plates that slide inside the socket shaft. There is a pin on the side of the socket shaft that holds the pin shaft in the hole. The lower end of the pin shaft has a flexible joint that absorbs vibration and "returns" from the steering gear. The stabilizing pin goes through the connection and prevents it from bending (acting like a universal joint), while allowing rotation and longitudinal movement. The joint is molded in rubber and has nylon fibers around the mounting holes through which the torque applied to the steering wheel is transmitted. The connection is attached to the drive flange, which is part of the pin shaft, and to the U-yoke, which is connected to the pinion yoke by means of a universal joint.
