About a year ago , I took it apart and greased the bearing . You Tube has videos that show how . That fixed it until the squealing came back a couple days ago . This time I decided to change the bearing , the belt looked dry and cracking , so I ordered both . The screeching may have been from the plastic bearing wearing down to the metal bracket . I may have been able to grind down the metal bracket , but the plastic bearing is cheap enough . I changed both and no more screeching , I kept the old belt for a spare . Mine has a small metal ball that I think centers the drum in the middle of the bearing , be careful not to lose that . It's a little tricky to get the 2 metal brackets back together , one from the front and one from the back , but not too bad . I used some grease to hold the metal ball in place until I got a screw started in the rear bracket .
