What are the symptoms of a broken car control arm?

Control arms are connected to the vehicle body with rubber bushings, which serve to absorb vibrations and reduce noise. Over time, these rubber bushings are prone to aging and damage. When this happens, the front of the vehicle may produce a clunking noise when driving on bumpy roads or during braking, and the chassis may feel noticeably loose. In such cases, it is necessary to replace either the control arm bushings or the entire control arm. Below is an introduction to control arm usage:1. During normal driving, when passing over speed bumps, potholes, or encountering obstacles, the undercarriage may scrape or the vehicle may drop off the road edge, potentially damaging the control arm. If this occurs, ensure safety first and immediately move the vehicle to a secure location. If the vehicle cannot be driven out, call for roadside assistance to request a tow truck.2. Once the vehicle is in a safe location, park it on level ground and straighten the steering wheel. Visually inspect the four tires for any obvious abnormalities. If abnormalities are found, the control arm may be severely deformed, and it is not advisable to continue driving. The vehicle should be towed to a repair facility for inspection. If no abnormalities are visible, drive the vehicle for a short distance to check for any pulling to one side. If the vehicle pulls to one side, take it to a repair facility for a wheel alignment. If the alignment cannot be adjusted properly, it may be necessary to replace the control arm.
When my car's control arm failed, it gave me a real headache. The chassis made loud clunking noises while driving, with particularly harsh metallic squeaking sounds during turns. On straight roads, the steering wheel kept pulling to one side, requiring constant forceful correction to maintain alignment, and the car shook violently at highway speeds. The tires also showed abnormal wear patterns, with the inner edges wearing down rapidly - new tires would be bald within weeks. The mechanic explained that control arms connect the wheels to the frame, and when damaged, they degrade handling, amplify bump impacts, and increase tail swing during turns. What really scared me was when the car nearly lost control during emergency braking due to excessive wobbling. I'd advise fellow drivers not to ignore these symptoms - get your suspension components checked and addressed promptly for safety.
Last time I drove my mom's car, I noticed the control arm was broken with obvious symptoms. There was constant clicking noise from the wheel area, especially when going over speed bumps or small potholes - the sound was particularly loud and clearly audible inside the car. The steering wheel felt unstable, didn't return to center properly after turns, and the car would gradually drift when driving straight, feeling like skating. Upon checking the tires, I found one side wearing faster than the other with uneven tread. A friend told me this is called poor handling. Only after repairs did I learn it affects suspension stability and may increase tire blowout risks. Now I pay attention to these details when driving, making it a habit to check the undercarriage condition to avoid nighttime accidents. Regular maintenance can extend a vehicle's lifespan.
