The drum seems to be slipping and squeaks.It also hug up once like the belt is slipping.I gave it a spin and It works fine for now.
How is the best way to get to the belt,idler pulley,and support wheels to replace them? Do you recommend any other replacements while I have it apart?
Those parts should do it. Be sure and clean out everything, particular the lint chute.
To get it open take out the two screws under the lint screen and use a screw driver to insert in the gap between the top and front near the edges to pry up the top. It will flip back and you can now take off the front, and get to everything. Release the belt, take out the drum and there you go.
