Why Does the Car Body Sway at Low Speeds?
2 Answers
The reasons for car body swaying at low speeds are: 1. Incorrect dynamic balance data of the vehicle; 2. Wear and looseness of the wheel bearings; 3. Bulges or unevenness on the tire tread. Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling contact with the ground, usually installed on metal rims. They support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Precautions for using car tires include: 1. Ensure the tread is free of cracks and regularly inspect the tire surface for defects like cracks or deformations; 2. Avoid parking the vehicle on roads with large, sharp, or pointed stones; 3. Do not splash water for cooling; 4. Minimize frequent use of brakes and emergency braking; 5. Choose smooth roads for driving.
I've been driving for over twenty years and have encountered body sway at low speeds a few times. Usually, tire imbalance is the prime suspect, such as a deformed wheel rim or missing balancing weights, requiring a dynamic balance check. Suspension system issues are also significant—leaking shock absorbers or aging springs can cause noticeable sway during turns, especially in older cars. It's also essential to check if the tire pressures are uniform, as uneven pressure can amplify the sway. Worn drive shafts might also cause vibrations at low speeds. I recommend a comprehensive inspection at a repair shop—don't skimp and try to fix it yourself. If the issue occurs at high speeds, it could be dangerous. Safety comes first. Bring a tool to check the tire pressure first; it's best to address minor repairs early.
