Why don't repair shops replace the triangular arm bushings?

[Gabriela]

Triangular arm bushings are not replaced by repair shops because the replacement process is relatively troublesome, and the cost of replacement is not high, so many repair shops are reluctant to replace them. The introduction of triangular arm bushings is as follows: Introduction to Triangular Arm Bushings: The triangular arm refers to the swing arm, whose function is to provide balance and support. When a car drives on uneven roads, the tires will move up and down, which is accomplished by the swing of the triangular arm. The tires are mounted on the axle hub, which is connected to the triangular arm via a ball joint. Working Principle of Triangular Arm Bushings: The triangular arm is essentially a universal joint, allowing connected movement even when the relative positions of the driving and driven sides change. For example, during steering, the shock absorber is compressed, causing the A-arm to tilt upward. Repair and Maintenance of Triangular Arm Bushings: When the triangular arm becomes deformed, the ball joint is damaged, or the bushing ages, repairs are necessary.
