Intermittent Squealing sound ..Getting worse

First of all I looked at the Video, which made it a lot easier. I decided to replace both rollers, the idler pulley, the idler bracket, and the belt so I should be fixed for a while. Installing the parts was not that hard. When installing the drum turn it by hand to make sure their are no binds, this will also insure the belt is not twisted and the felt around the drum is installed correctly. The hardest thing was getting all the panels back together with the right screws. Use a small screwdriver to line up the holes. Parts Select resources on their web site make it easier for the handyman to complete this repair. Parts were in Stock, at a fair price, and received in two days on normal delivery. I will use you again and give you a 10 on your service....
