How Often Should the Lower Control Arm Be Replaced?

[VonKai]

Generally, the lower control arm of a car needs to be replaced every 80,000 to 120,000 kilometers. Below is relevant information: 1. Reason: Most car components are connected using rubber to absorb vibrations, which can easily wear out over time. In front-wheel-drive vehicles, the front suspension tends to fail before the rear suspension. 2. Function of the Lower Control Arm: If the rubber bushings of the lower control arm are damaged, it is best to replace the entire set. The lower control arm, one of the suspension arms in a car, primarily supports the vehicle body and shock absorbers while cushioning vibrations during driving. The shock absorber provides excellent auxiliary support to the lower suspension. 3. Effects of Damaged Lower Control Arm Bushings: Steering may become less responsive or produce noise, the vehicle body may become misaligned, and there may be vibrations during high-speed driving. If the rubber bushings are completely broken, replacement is mandatory. The lower control arm is a crucial component connecting the front axle to the tires. Once it fails, the tire alignment changes, and other connected components may also be easily damaged.
