Should the Worn-out Rubber Bushings of the Car's Control Arm Be Replaced?
2 Answers
Car control arm rubber bushings need to be replaced when they are worn out. The lower control arm is a crucial component connecting the front axle to the tires. Once severely worn, the tire angle will change, and other connecting parts can easily get damaged. The car may produce abnormal noises while driving, the shock absorption effect will deteriorate, and steering will become heavy. In severe cases, it may lead to control arm breakage, resulting in vehicle loss of control and accidents. Therefore, it is best to replace them promptly. The rubber bushings on the car's suspension control arm generally cannot be replaced separately, and they are not sold individually. Thus, when replacement is needed, the entire suspension control arm must be replaced. The main function of the car's lower control arm is to support the body and the shock absorber, as well as to buffer vibrations during driving. The shock absorber plays a significant auxiliary role for the lower suspension. Only with the cooperation of the shock absorber and the spring can a complete suspension system be formed. The rubber bushings on the lower control arm serve a fixing role and connect to the shock absorber.
As an experienced driver who has driven many cars, I've found that worn-out control arm bushings must be replaced. This small component is crucial in the suspension system. When it deteriorates, the rubber hardens and cracks, causing suspension joints to loosen and resulting in unstable driving. During turns, the car body shakes excessively, increasing the risk of losing control and causing accidents, especially in rainy conditions or at high speeds. Neglecting it can trigger a chain reaction, wearing out shock absorbers and bearings, doubling repair costs. While driving, pay attention: squeaking noises on bumpy roads or steering wheel vibrations are signs of aging—immediately visit a professional shop for replacement without hesitation to save a few bucks. Safety first. It's recommended to inspect them every 30,000–40,000 kilometers and replace them early to prevent issues, ensuring smooth and reliable handling.
