I watched the repair video twice and ordered the dryer repair kit for my Whirlpool Duet Sport Electric Dryer Model WED8300SW1. My dryer was a bit different than the one in the video, but most of the repair process was similar. Replacing the belt and rollers eliminated the noise.
The repair video was a great reference. I also found a "Tech Sheet", service trouble-shooting guide
stored in the dryer's toe panel that provided disassembly information for my particular model. The electronics console panel on my dryer had different locking tabs than the model in the video
My dryer is at least 6 years old, so it required a good deal of vacuuming as I took it apart. Everything
came apart methodically as described, fairly easily. I was able to work from the front of the dryer in our laudry closet without having to disconnect the vent, or even move the dryer.
The dryer's panels, electronics assemblies, and door come apart fairly easily, but the order is
important. Two hands are needed to retract the belt tension pulley and loosen the belt. The
drum is a bit awkward to remove in a confined space, but it is not very heavy.
I used alcohol to clean off the roller axels, once I had removed the old wheels. The triangle clips were
a bit difficult to remove, particularly the ones further back on the axels. Reviewing the video helped.
I added a small amount of bearing grease on the axels before installing the new rollers.
I used a small amount of stove-top cleaner to remove gunk built up on the front and rear enamel surfaces that the felt drum gaskets rub as they spin. I used comparable electronics-grade cable ties to replace three of the original ties that I cut to move the electronics assemblies or make it easier to disconnect cables.
It may be obvious, but the guy in the video is wearing mechanics gloves to avoid getting his hands cut by the sharp edges on the various sheet metal panels -- a really good idea!
This was a somewhat time-consuming, but straightforward undertaking. The repair video as well as advice from others was very helpful and much appreciated. Hopefully, I gained a couple of more years use from the dry. In any event, it runs very quiet and smoothly, and I'm happy with the results.
Thank You.
