Diagnosing the cause of a squeaky clothes dryer is often more difficult and time-consuming than making the actual repair. Depending on the make and model of your dryer, squeaks may be caused by a worn tub support roller, worn rear drum mount bearings, worn belt idler pulley, worn front glides or felt, worn blower squirrel cage bearings or even worn drive motor bearings.
Most squeaks are drum-related, meaning the problem is with the rear bearing, support rollers, front glides, felt or idler pulley. The good news is that all these parts are relatively inexpensive and easy to replace.
A worn dryer drum bearing can begin to squeak and squeal as the drum spins.
A drum bearing looks like a large bolt through the back wall of your drum. This repair is slightly more complicated as it requires releasing the drum belt, removing the drum from the dryer to access the bearing, and releasing the element housing from the rear wall of the dryer to replace the bearing housing.
The element housing connects to the rear wall with plastic pins you can access from the back of the dryer and four screws you can access from the front.
This allows you to leave the element wiring connected to the dryer while you replace the bearing housing. The dryer bearing connects to the dryer drum with torx-head screws. Have a set handy to help remove and replace the drum bearing.
