The repair video is very good. The putty knife kinda worked to open the top lid. However, I broke both front brittle plastic clips. The replacement metal ones are much better. The Rear Drum Support Roller Kit bag had a hole in it and was missing one of the triangular plastic retaining clips. My local hardware store had a 1/2" steel E-clip that worked fine. The bushing inside the roller is a centered bearing. This style bearing must be soaked overnight in a light turbine oil. I used a turbine oil with Teflon made for skateboard wheels. Once the bushing material has fully absorbed the oil, it will stop foaming & it's lubricated for life. Now, take rubbing alcohol & a paper towel and remove all traces of the oil on all surfaces. Not doing this oiling procedure is probably why people are reporting multiple bearing failures shortly after installing these rollers. I cleaned & soaked the centered bushing in the belt tension idler pulley too. Then I put on a new belt just because I had the old one out. I also took the rest of dryer apart and vacuumed out the accumulated lint in it and the vent hose system. The dryer now runs smoothly & quietly.
