What Causes Steering Wheel Vibration When Turning in Place?
2 Answers
Reasons for steering wheel vibration when turning in place: Loose steering gear bearings or excessive clearance in the steering gear meshing transmission pair; Wear and looseness of the main and tie rod ball joints, causing looseness; Severe wear of the steering knuckle kingpin and bushing, resulting in excessive clearance; Loose front wheel hub bearings; Bent front wheels or loose rivets; Deformation of the frame and wheel rim; Excessive toe-in. Steering wheel vibration is relatively common: Steering wheel vibration while driving is a relatively common vehicle issue encountered during daily driving. Steering wheel shaking and body resonance can lead to unsafe driving conditions. Solutions include: Cleaning the throttle body; Inspecting or replacing spark plugs; Checking for air leaks; Using a computer to check for fault codes.
This is a problem that every driver has encountered. The steering wheel shaking when turning it while stationary is mainly caused by friction between the tires and the ground. When the car is not moving, turning the steering wheel requires more force, and the power steering system has to work harder. For example, in a hydraulic power steering system, if the oil pump pressure cannot keep up, it will shake; in an electric power steering (EPS) system, insufficient motor output can also cause vibrations. When the tire pressure is too low or the tires are severely worn, the grip increases, making the vibrations more noticeable. If the bearings or linkages in the steering column are worn, the burden of stationary operation is greater, making it easier to feel the shaking. It is recommended to regularly check whether the tire pressure is standard and whether the tires are balanced. If you experience vibrations, don't force it—drive to a repair shop to check the power steering system or replace components. Remember, turning the steering wheel while stationary causes significant damage to the car, so try to steer while the wheels are rolling to protect the components.
