1. Tires - One of the most common causes of steering wheel vibration is worn or unbalanced tires. If your tires are worn, they can create an uneven surface that causes the steering wheel to vibrate. Similarly, if your tires are not balanced properly, the weight distribution can cause shaking. To fix this issue, have your tires inspected and rotated regularly.

2. Wheel Alignment - Another cause of steering wheel vibration is a misaligned wheel. If your wheels are not aligned properly, it can cause uneven wear on your tires, which leads to vibration. To prevent this from happening, have your wheels aligned regularly, especially if you hit a pothole or curb.

3. Suspension Issues - If your suspension system is worn or damaged, it can also cause steering wheel vibration. The suspension system is responsible for absorbing shocks and keeping your car stable. If it's not functioning properly, it can lead to a bumpy ride and vibration. Have your suspension system inspected by a professional mechanic to determine if there are any issues.

4. Brakes - If your brakes are worn or damaged, it can also cause steering wheel vibration. This is because the rotors can become warped, causing the steering wheel to shake when you brake. Have your brakes inspected regularly to ensure they are functioning properly.

5. Power Steering - If your power steering system is malfunctioning, it can also cause steering wheel vibration. This is because the power steering system helps to stabilize the steering wheel. If it's not functioning properly, it can lead to vibration. Have your power steering system inspected by a professional mechanic to determine if there are any issues.
