What are the symptoms of a bad car control arm?

Car control arm failure symptoms include: 1. Reduced handling and comfort; 2. Decreased safety performance (such as steering, braking, etc.); 3. Abnormal noises; 4. Inaccurate alignment parameters and deviation; 5. Wear or damage to other components; affected or failed steering. The car lower control arm, also known as the car lower suspension, is an important component in a vehicle. Although small, it plays a crucial role in supporting the car body, working together with the car's shock absorbers and springs to form the suspension system. The car lower control arm is a key component of the chassis suspension system, elastically connecting the car body and the wheels. When the vehicle is in motion, it elastically connects the axle and the frame through the lower control arm, mitigating the impact caused by road conditions, thereby ensuring ride comfort.
While driving, I noticed something was wrong with my car. The most obvious sign was loud banging noises when going over potholes or speed bumps, like metal hitting metal. When turning, the car felt unstable, with the body leaning heavily to one side, and several times I almost thought it would roll over. Even when driving straight, I had to forcefully steer the wheel in the opposite direction just to barely keep it stable. The tires wore out unusually fast, becoming uneven in less than six months. Later, during a check-up, the mechanic identified it as a control arm issue. After replacement, everything returned to normal. This kind of fault seriously affects handling safety, so I recommend paying close attention to unusual noises and changes in driving feel during daily driving. If you notice anything, pull over and get it checked. My advice is not to save small money—get it fixed promptly to avoid major accidents.
