What are the signs of aging in a car's control arm bushings?

[TaliaAnn]

The manifestations of aging in a car's control arm bushings are as follows: decreased handling and comfort, reduced safety performance, abnormal noises, inaccurate alignment parameters, vehicle deviation, and wear or damage to other components (such as tire wear), affecting steering and even leading to malfunctioning performance. The precautions for using car control arms are as follows: 1. Shock absorption: The function of the control arm is to absorb vibrations during driving, with shock absorbers used in conjunction to provide cushioning. 2. Materials: Control arm materials are quite diverse, including aluminum alloy, cast iron, double-layer stamped parts, and single-layer stamped parts, each with its own advantages and disadvantages. Stamped parts have good toughness but insufficient strength, making them prone to fracture upon impact. 3. Rust prevention: It is generally easy to check for rust on the lower control arm, as it is located at the connection point between the front wheel tire and the car's central body. If rust is detected, it must be addressed promptly at a 4S shop to prevent unexpected breakage.
