I've replaced the rear plastic bearing on this dryer twice, so I am familiar with taking the unit apart. After replacing the bearing in December, the machine still made noise (which had been masked by how loud the bearing was). The belt didn't look so great and it's 13 years old, so I ordered one and a new idler pulley assembly.
First, I disconnected the power and pulled it out for access. Using a large blade screwdriver, popped the cover open from the two clips in front. Be sure to support the top cover when you open it on the tabs or they will bend - I propped it against the wall. I disconnected the two wires that go to the door switch, and then removed the two screws that hold the front panel and door in place and lifted/opened that and removed the front panel and set it aside.
Next, I removed the back access grill (2 screws) and popped the belt off the idler by relieving the tension on the belt. Using a 10mm socket, I removed the idler pivot bolt and idler arm assembly. I installed the new idler arm assembly in its place and reattached the spring.
Moving to the front of the dryer, I lifted the drum off the blower housing on which it was resting and took off the belt through the front of the dryer. I then replaced the belt in reverse. Back through the access panel on the rear, I put the new belt on the motor and idler.
Be sure to check that there are no flips in the belt. I rotate the drum by hand a couple of revolutions to be certain.
I then reinstalled the front cover and door, reconnected the door switch, replaced the access panel and put the cover back down, popping the clips into place.
Put the dryer back in place, reconnected the exhaust and plugged it in. Voila - quiet dryer.
As an aside, I also took the time to clean the lint out of the blower and exhaust with a vacuum cleaner hose.
