Bosch Dryer vibrating or shaking
If your Bosch dryer is vibrating or shaking while it runs, the most likely culprit is wear in the drive motor or motor bearings that prevents smooth drum rotation. A noisy motor often makes a grinding sound, and if the motor shaft won’t turn freely by hand the motor should be replaced. After the motor, worn drum support bearings commonly cause rough rotation and vibration. Worn or missing felt seals on the drum or bulkhead can let the drum wobble, and a bad idler pulley or idler assembly that sticks or has worn bearings can let the drive belt slip and make the dryer shake. Listen for grinding or squeaking and try turning the drum by hand to narrow the cause; visually inspect seals, bearings and the idler for obvious damage. Once you identify the failed component, enter your model number at RepairClinic.com to find the exact replacement part and step-by-step instructions to get your dryer running smoothly again.
01 - Bosch Dryer Drive Motor
A drive motor that is wearing out will be unable to rotate the dryer drum efficiently, resulting in the dryer vibrating or shaking during operation. As the motor bearings began to wear out, the drive motor will often make a grinding noise. If the motor is noisy or the motor shaft does not turn freely by hand, the component should be replaced.

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.

04 - Bosch Dryer Felt Seal
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.

05 - Bosch Dryer Idler Pulley
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.
Highly Likely
06 - Bosch Dryer Idler Assembly
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.
Highly Likely
