* Balance issues: Unbalanced tires or wheels are a very common cause of shaking, especially at higher speeds.
* Drivetrain problems: Issues with the transmission, driveshaft, or differential can cause vibrations.
* Suspension problems: Worn-out shocks, struts, or other suspension components can lead to shaking.
* Brakes: Warped brake rotors can cause noticeable shaking, particularly when braking.
* Engine mounts: Worn engine mounts can allow the engine to vibrate more than it should.
* Other engine issues: Problems beyond a simple tune-up, such as worn spark plugs, ignition coil issues, or a failing catalytic converter, can also cause shaking.
To determine the *cause* of the shaking, it's best to have a mechanic diagnose the problem. They can perform a thorough inspection and identify the specific issue, which may or may not be related to needing a tune-up.
