If your dryer does not tumble, will not start, is noisy, or is leaving marks on your clothing, you may need to replace the drum support bearing. The drum is supported at the rear by a bearing, which attaches onto the inside of the rear panel of the cabinet. You will need to remove the dryer drum before completing this repair. Although replacing the drum support bearing is a fairly easy job, you will need tools to complete it. For this repair, you will need a putty knife, a Phillips screw driver, a 5/16 nut driver and maybe a small flat blade screw driver.
