Over bumpy roads, the reasons for steering wheel vibration are: 1. Timing belt failure; 2. High brake pad temperature; 3. Wheel hub deformation; 4. Loose tire nuts; 5. Steering system malfunction; 6. Unbalanced suspension support; 7. Incorrect four-wheel alignment data; 8. Worn or loose tie rod ball joints or detached rubber bushings at the joints. Methods to address steering wheel vibration: 1. Adjust the transmission system; 2. Replace the tires; 3. Replace the tie rod ball joints and joint rubber bushings; 4. Replace the brake pads. The steering wheel is connected to the steering shaft via splines, and its function is to convert the force applied by the driver on the steering wheel rim into torque, which is then transmitted to the steering shaft.
