Pete R Denver , CO July 24, 2016 Appliance: LG Dryer DLE2514W Lg Dryer Dle2514w: Loud squeaking sound during operation. How to replace Dryer Idler Pulley Assembly. Wasn't sure what was making the sound so I ordered all 4 drum rollers, belt and pulley. When I opened the dryer it was obvious one of the front drum rollers had seized with lint and hair buildup. I still replaced all the parts and it works great again. The videos on Parts Pros were exceptional and essential to this DIY repair! The dryer was fairly dirty and cleaning every part as I went along added extra time to my repair but I figure actual repair time to be about 1 hour. 45 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
