What are the symptoms of a damaged car swing arm?

Symptoms of a damaged car swing arm: 1. The steering wheel will shake when driving at high speed; 2. There will be noise from the chassis when driving on bumpy roads, and abnormal sounds will come from the steering wheel. The lower swing arm, commonly known as the lower suspension, is mainly used to support the car's shock absorber and buffer vibrations during driving. After the lower swing arm ball joint is damaged, it will directly affect the comfort and safety of the car. You can use a jack to lift the car and then repeatedly check the wheel by turning it left, right, up, and down multiple times to determine whether the steering gear ball joint or the swing arm ball joint is damaged. Hold the tie rod or straight rod with your hands and shake it left and right to see if there is any looseness. If it can be moved by hand, it needs to be replaced promptly.
I feel the steering wheel shakes a bit when driving, especially when going over speed bumps or rough roads—it vibrates so much that it's hard to keep a firm grip. The steering isn't very responsive, and the car tends to pull to one side, requiring constant effort to keep it straight. There's also a strange noise from the chassis, like a metallic clicking or grinding sound, which becomes more noticeable when turning. After driving for a while, the tires wear out unusually fast, with sawtooth-like wear patterns on the tread. If the control arm is damaged and not addressed promptly, the suspension system will deteriorate further, compromising driving safety and increasing the risk of rear-end collisions. I recommend regular inspections of the wheel suspension components to maintain good vehicle condition.
