* Unbalanced tires. This is the most common cause of a shaking steering wheel at high speeds. When tires are unbalanced, they create a centrifugal force that causes the steering wheel to vibrate.
* Bent wheels. Bent wheels can also cause the steering wheel to shake. This is because the bent wheel will cause the tire to wobble, which in turn will cause the steering wheel to vibrate.
* Worn suspension components. Worn suspension components, such as ball joints, tie rods, and control arms, can also cause the steering wheel to shake. This is because worn suspension components allow the wheels to move out of alignment, which can cause the steering wheel to vibrate.
* Driveline problems. Driveline problems, such as a bent driveshaft or a worn universal joint, can also cause the steering wheel to shake. This is because driveline problems can cause the wheels to rotate at different speeds, which can cause the steering wheel to vibrate.
What to Do
If you experience a shaking steering wheel at high speeds, it is important to have your car inspected by a qualified mechanic as soon as possible. This is because a shaking steering wheel can be a sign of a serious problem, such as unbalanced tires, bent wheels, worn suspension components, or driveline problems. By having your car inspected, you can help to ensure your safety and the safety of your passengers.
