* Wheels and Tires: Uneven tire wear, imbalanced tires, bent rims, or improperly inflated tires are common causes of shaking. This is often felt most strongly at higher speeds.
* Suspension: Worn-out shocks, struts, ball joints, tie rod ends, or control arm bushings can all lead to shaking and instability. This might be felt at various speeds and during turns.
* Drivetrain: Problems with the driveshaft, U-joints (universal joints), differential, or transmission can cause shaking, often felt at specific speeds or under acceleration/deceleration.
* Brakes: Warped rotors or sticking brake calipers can cause shaking, particularly when braking.
* Engine: While less common, engine problems, such as a misfire or imbalance, can create vibrations that translate into a shaking feeling.
To find the source, you'll need to have a mechanic inspect the truck. They'll likely perform a visual inspection, check tire pressure and wear, and potentially do a road test to identify the problem.
