How to replace Dryer Drum Support Roller. I watched the AppliancePartsPros youtube video on how to replace the drum rollers and decided to buy the parts from AppliancePartsPros.com. I decided that as long as I had the dryer apart, it would be a good idea to replace not only the rollers, but the drum roller axles, front bearings, the drum belt and the hi-limit thermostat so I wouldn't have to go back into the dryer for a long time. The disassembly was very straightforward and was almost identical to the video. Our dryer had two more screws than the video showed, but it was not a problem. When I finished the the disassembly, the roller on the left had rust coming out of the axle area, so I knew I had found the source of the sound - I was happy I ordered the axles to go with the rollers. I spent the bulk of my time cleaning out all of the lint and dust on the inside of the cabinet and there was a lot of lint build up below the lint trap. I did call the AppliancePartsPros hotline because there were no instructions on what lubricant to use for the rollers. I was advised to use a graphite lubricant. Installation of all of the new parts was just the reverse of disassembly. We've now run a load through it and it is as quiet as new! I ended up using a #2 Phillips Screwdriver, 5/16" and 1/4" nut drivers, an 1/8" drill bit and a pop rivet tool to complete this project. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
