If your Speed Queen dryer is vibrating or shaking during a cycle, the most likely culprit is a worn drive motor or motor bearings that can no longer rotate the drum smoothly. A bad motor often shows up as a dryer making grinding noise or a dryer squeaking when the drum turns, and the motor shaft may not spin freely by hand. Next likely causes are a worn drum support bearing or damaged felt seals that let the drum wobble, followed by a stuck or worn idler pulley or idler assembly that prevents the belt from tracking smoothly. All of these faults can make the dryer making noise when drum turns or the dryer making loud noise and will produce the vibration you feel. You can inspect the motor, support bearings, felt seals and idler pulley for visible wear, free rotation, or damage, and replace the faulty part to stop the shaking.

A worn drum support bearing will interfere with the smooth rotation of the dryer drum which can cause the appliance to vibrate or shake during operation. A support bearing the shows excessive wear or damage will need to be replaced to fix the problem.
Felt seals can be found on the front or rear bulkhead of the dryer or on the front and back rims of the drum itself. A worn or missing felt seal can interfere with the dryer drum rotating smoothly, resulting in the appliance vibrating or shaking during operation. Inspect the felt seal or seals for wear or damage and replace as necessary.
A worn or stuck idler pulley may be unable to smoothly allow the drive belt to rotate the drum efficiently, resulting in the appliance vibrating or shaking. Inspect the pulley for any wear or damage and confirm it rotates freely. If the pulley shows signs of damage or doesn't turn easily it should be replaced.
A worn or stuck idler assembly may be unable to smoothly allow the drive belt to rotate the drum efficiently, resulting in the appliance vibrating or shaking. Inspect the idler assembly for any wear or damage and confirm the pulley rotates freely. If the assembly shows signs of damage or the pulley doesn't turn easily the idler assembly should be replaced.
