A car steering wheel can shake while driving due to various mechanical issues and imbalances within the vehicle’s components.
Here are some common reasons, according to mechanicbase.
Wheel Alignment Issues: Incorrect wheel alignment can cause the steering wheel to vibrate as it struggles to maintain a straight path.
Tire Imbalance: Uneven tire wear or improper tire balancing can lead to vibrations in the steering wheel, especially at higher speeds.
Worn Suspension Components: Worn-out shocks, struts, or bushings can cause instability, leading to steering wheel shakes.
Brake Problems: Warped brake rotors or uneven brake pad wear can result in vibrations when braking, affecting the steering wheel.
Wheel Bearing Problems: Damaged or worn wheel bearings can create a wobbly feeling in the steering wheel.
Steering System Issues: Faulty components like tie rods, ball joints, or the steering rack can lead to steering wheel vibrations.
Drivetrain Problems: Issues with the driveshaft or CV joints can cause vibrations that transfer to the steering wheel.
Tire Issues: Damaged or out-of-round tires can lead to steering wheel shakes.
Wheel Hub Problems: Bent or damaged wheel hubs can contribute to vibrations in the steering system.
Engine Issues: Engine misfires or problems with motor mounts can cause vibrations that may be felt through the steering wheel.
