The pull rod ball head of a car is usually located on the inner side of the guide wheel. Its main components include tie rods and straight rods, both of which are connected by ball joints. The main function of the tie rod is to adjust the toe in, while the straight rod is used to adjust the operation of the steering wheel.

The state of the pull rod ball head has a direct impact on the steering effect of the vehicle. Under normal circumstances, if the rubber sleeve of the ball head is not damaged, the grease is not dry, the ball head itself is not loose, and the pull rod has not been deformed by collision, then there is no need to replace the pull rod ball head.

Every time you perform car maintenance, you should carefully check the condition of the pull rod ball joint. The pull rod ball head is composed of a pull rod with a ball head shell, which includes a force transmission pull rod that is remotely controlled from below the front wheel of the car and a connected universal ball head.

Inside the ball head housing, there is a ball head with a steering spindle. The ball head is hinged to the edge of the shaft hole of the ball head housing through the ball head seat at its front end. At the same time, the needle roller between the ball head seat and the steering spindle is embedded in the inner hole groove of the ball head seat. This structural design aims to reduce the wear of the ball head and improve the tensile performance of the spindle, thereby ensuring the precision and safety of the vehicle's steering.
