What causes the steering wheel to pull to one side?
1 Answers
Steering wheel pulling to one side may be caused by the following situations: 1. Uneven cushioning due to deformation of front shock absorber springs on both sides. The condition of the shock absorber springs can be judged by pressing or comparing after disassembly. 2. Failure of the front shock absorber. After the front shock absorber fails, the vehicle's suspension will be uneven during driving, causing uneven force distribution and resulting in pulling. The absorption of the shock absorber can be tested with a specialized testing device to determine its condition. If no equipment is available, disassembly and stretching can be used for judgment. 3. Unequal tire pressure is a major cause of vehicle pulling. The position of the tires should be rotated every 20,000 kilometers, as the wear on the drive wheels is always greater than on other wheels, and different friction can directly cause pulling. 4. Poor return or incomplete separation of a wheel's brake. This is equivalent to applying partial braking on one side, which will inevitably cause the vehicle to pull. During inspection, the temperature of the wheel hub can be checked. If one wheel is significantly hotter than others, it indicates poor brake return. 5. The condition of the steering system also affects the vehicle's straight-line driving. Excessive wear gaps in connecting parts or looseness caused by wear in bearings, kingpins, or bushings will cause the vehicle to sway during driving and fail to maintain a normal trajectory. If the steering knuckle arm or steering knuckle is bent or deformed, it usually causes the vehicle to pull to one side. The most severe case is severe wear and detachment of the tie rod ball joint, which will lead to steering failure and complete loss of vehicle control.
