What Causes Vehicle Shaking During Low-Speed Turns?
2 Answers
The vehicle's half-shaft, under long-term torsional fatigue and impact forces, is prone to faults such as bending, twisting, fracture, spline tooth wear, or skewing. This can lead to rhythmic shaking of the car's front when accelerating within a certain speed range, with the shaking disappearing or reducing upon releasing the throttle. Engine Operation Aspects: Since the car jerks when accelerating, the issue is likely related to engine operation. For the engine to function properly, it requires sufficient air, adequate fuel, and a well-functioning ignition system. Any problem in these areas can cause the engine to shake. Fuel System Considerations: The vehicle's fuel system is extensive and comprises many components. Any abnormality or malfunction in one of these components can result in engine shaking during acceleration. Examples include excessive carbon buildup in the throttle body, fuel injector failure, fuel pump malfunction, or a clogged fuel filter.
After driving for a long time, I've encountered many cases of low-speed steering wheel vibration. Common causes include insufficient tire pressure or uneven tire wear, which can lead to poor grip and vehicle wobbling. Additionally, aging ball joints or bushings in the suspension system may cause instability during turns, resulting in vibrations. Damaged wheel bearings can also produce noticeable friction noise during cornering. If there's an issue with the power steering system, the steering wheel may vibrate during low-speed turns. It's recommended to first check if tire pressures are equal, or try shaking the wheels to check for looseness. Untreated issues may accelerate wear on other components. Remember to make gentle turns while driving and avoid sudden steering movements.
