What are the symptoms of a broken car control arm?

Symptoms of a broken car control arm: 1. While driving, you may feel looseness in the chassis suspension and sometimes hear abnormal noises; 2. At high speeds, the vehicle's stability is not as good as before, handling becomes worse, and the direction cannot maintain a straight line; 3. If the control arm bushing is broken, it will also cause increased play between the suspension control arms. When driving on bumpy roads, there will be abnormal noises from the chassis, and the play in the chassis will also increase, which will affect the overall driving quality of the vehicle. The main function of the control arm is to support the body and shock absorbers, and to buffer vibrations during driving. The shock absorber plays a good auxiliary role for the lower suspension. The lower control arm, shock absorber, and spring work in harmony to form a complete suspension system, with the lower control arm responsible for supporting weight and steering.
Having driven for over twenty years, I've noticed that when the car's control arm is damaged, the body shakes violently, as if encountering waves on a boat. Especially when driving on uneven roads, the whole body feels jolted up and down, and the steering wheel becomes loose and unresponsive, requiring a firm grip to stabilize during turns. Sometimes, you can hear creaking or knocking sounds, like metal rubbing against metal, which makes you worry the car might fall apart. Tire wear becomes uneven, with a significant difference between the inner and outer edges, and the outer edge may wear down to be very thin. During acceleration or braking, the whole car sinks or sways, resulting in poor handling. Driving at night is even more dangerous, as visibility is already poor, and an unstable body makes it easy to lose control. I recommend going to a repair shop for inspection promptly—don't delay, as small issues can turn into major hazards.
When I was driving on the highway before, my car suddenly started shaking violently, as if it could flip over at any moment. Later, it was found out that the control arm was broken. Symptoms included severe bouncing over small bumps, the car bouncing up and down, making the ride very uncomfortable. The steering feedback became weaker, feeling light and floaty when turning, losing the usual precision. There was obvious abnormal noise, with a clunking sound every time I went over a speed bump, as if parts were loose. The tires wore out quickly and unevenly on both sides, with one side possibly completely worn out. After driving for a long time, fatigue was intense, and the front or rear of the car would sag when accelerating. I immediately stopped to check, avoiding any accidents.
I've seen many faulty vehicles, and a common symptom of a bad control arm is abnormal noises, such as a thud sound when going over bumps. The tires wear out quickly and unevenly. The car feels unstable while driving, wobbling during turns or on uneven roads. The steering feels vague, and the steering wheel vibrates. The car shakes more when braking or accelerating. Timely repairs can ensure safety.
