What Causes Steering Wheel Vibration While Driving a Sedan?

[MariaDella]

Reasons for steering wheel vibration while driving a sedan: 1. Collision causing deformation of the steering tie rod and steering cross rod, wear and looseness of various ball joints, or irregular tire wear, leading to an increase or decrease in toe-in; 2. Loss or deformation of the original wheel dynamic balance lead blocks, causing the front of the car to wobble and the steering wheel to vibrate at high speeds; 3. Looseness of the transverse thrust rod ball joint or loose bracket; 4. Looseness of the wheel hub bearings and severe wear of the left and right steering knuckle ball joints, resulting in inaccurate front wheel alignment; 5. Damage or oil leakage of the steering shock absorber, or deformation of the front suspension spring. During the repair process, various connection parts of the vehicle's steering system are usually carefully inspected according to different conditions, such as the steering wheel play, toe-in, front wheel alignment, wheel dynamic balance, suspension springs, and steering shock absorber. The issues are identified and adjusted, repaired, or replaced with new parts to restore the vehicle's original stability and ensure driving safety.
