What Causes Vehicle Body Shaking at Low Speeds?
2 Answers
The reasons for vehicle body shaking at low speeds are: 1. Aging engine mounts, causing vibrations to transmit to the steering wheel and cabin; 2. Increased load from turning on electrical systems, leading to engine idle speed drop; 3. Deformed wheel rims, uneven wheel rim weight distribution, and incorrect wheel alignment angles; 4. Dirty throttle body and excessive carbon buildup in fuel injectors. When driving through waterlogged sections, promptly shift to a lower gear and press the accelerator pedal firmly to maintain high engine RPM and torque while passing through, reducing wheel slip risk, preventing water backflow into the exhaust pipe, and ensuring sufficient power to overcome water resistance and underwater obstacles.
I often experience body shaking when driving at low speeds, especially noticeable when turning or just starting off. This could be caused by unbalanced tires, uneven tire wear, or differing tire pressures, making the wheels unstable during low-speed rotation. Additionally, tire aging or foreign objects stuck in the tires can affect driving stability. It's recommended to first check the tire condition and perform a four-wheel alignment or dynamic balance adjustment, which usually helps alleviate the shaking. If the problem persists, inspect whether the rims are deformed or if the bearings are loose. For safety, visit a professional repair shop as soon as possible to get it checked—don't delay. Also, ensure tire pressure is normal before driving. Moreover, shaking is more easily noticeable at high speeds, but it particularly affects comfort at low speeds. Address the issue promptly to avoid more significant faults.
