Dryer was noisy. Sounded like loud squeaking noise.

Disconnect the dryer from the electrical source. Using a nut driver, first remove the 2 screws of the lower panel and release the panel. Next remove 4 screws of the door panel and then remove the electrical connections to the door (6 wires). Remember to mark the wires prior to removing so you will remember were it plugs back in on reassembly. Remove the door panel. Then remove the 2 screws holding the top of the dryer and tilt the top open about 90 degrees to access the tumbler. Remove the belt by sliding off the tumbler. Remove the tumbler. You will then access the pulley. Using a pair of pliers, remove the retaining ring by pulling upwards. Then remove the washer and the pulley. Replace the parts with the new pulley, washer and retaining ring. This time would be a good time to replace the belt too. Thread the belt through the pulley and over the tumbler. Place the top back and screw in place. Reassemble the door wiring and reattach the door with the 4 screws. Reassemble the lower panel and plug the dryer back into the outlet and test. There should be no more noise if the noise is coming from the pulley and loose belt.
