What causes steering wheel shaking?

There are various reasons why a steering wheel may shake. Here are some common causes:

Unbalanced Tires: Imbalanced tires can cause vibrations that are transmitted to the steering wheel. This can occur due to uneven tread wear, improper tire installation, or a damaged tire.

Wheel Alignment: Incorrect wheel alignment, such as toe-in or toe-out, can put uneven pressure on the tires, leading to steering wheel shaking.

Bent Rim or Wheel: A bent rim or wheel can cause vibrations that are felt through the steering wheel, especially at higher speeds.

Worn Steering Components: Worn steering components, such as tie rods, ball joints, or control arm bushings, can create excessive play in the steering system and lead to shaking.

Engine Issues: Engine problems, such as a misfire or a faulty spark plug, can cause the engine to vibrate excessively, which can be felt through the steering wheel.

Brake Issues: Warped brake rotors or worn brake pads can cause vibrations that are felt in the steering wheel when braking.

Tire Pressure: Incorrect tire pressure can also contribute to steering wheel shaking. Make sure the tire pressure is set to the recommended level specified by the vehicle manufacturer.

Driveline Problems: Issues with the driveline, such as worn universal joints or a damaged driveshaft, can cause vibrations that are transmitted to the steering wheel.
