Why Does My Semi Truck Steering Wheel Shake?

Semi truck steering wheel shake can be caused by a variety of different issues. It is important to identify the cause of the problem in order to determine the best course of action for the repair. Common causes of semi truck steering wheel shake include tire imbalance, worn or loose suspension components, worn wheel bearings, and damaged or underinflated tires.

Tire imbalance is one of the most common causes of steering wheel shake. When a tire is unbalanced, it will cause an uneven distribution of weight on the tire and wheel assembly. This can cause vibrations that are felt through the steering wheel and can be felt at all speeds.

Worn or Loose Suspension Components

Worn or loose suspension components can also cause semi truck steering wheel shake. Worn ball joints, tie rods, and control arm bushings are all common culprits when it comes to loose suspension components that can cause steering wheel shake. If these components are not replaced in a timely manner, they can lead to further damage to other parts of the vehicle’s suspension system.

Worn Wheel Bearings

Worn wheel bearings can also lead to semi truck steering wheel shake. This is because worn bearings create an uneven surface on which the tires rotate on. This uneven surface creates vibrations as the tires spin which are then transferred through the suspension system and into the cab where they are felt through the steering wheel.

Damaged or Underinflated Tires

Finally, damaged or underinflated tires can also cause semi truck steering wheel shakes. If a tire has been damaged due to driving over potholes or curbs then it could create an uneven surface on which it rotates on, leading to vibrations that are transmitted through the cab and felt through the steering wheel.


In conclusion, there are several potential causes for semi truck steering wheel shake including tire imbalance, worn or loose suspension components, worn wheel bearings, and damaged or underinflated tires.

Therefore it is important for drivers to inspect their rigs regularly in order to identify potential problems before they become larger issues.Why Does My Semi Truck Steering Wheel Shake?: Semi truck steering wheels may shake due to many factors such as tire imbalance, worn or loose suspension components, worn wheel bearings, and damaged or underinflated tires.
