I called in to the Appliance Parts Pros customer service number to ask questions about how many of the slides I would need - I wasn't sure whether it was 2 or 4. The guy I talked to recommended getting the Dryer Bearing Kit, Part No. AP5806906, as it was only a few dollars more than ordering the slides individually - and the kit had all the slides, the belt, duct trap felt and the top bearing. I also ordered the Idler Pulley separately. It was easy to follow the How To Videos on the Appliance Parts Pros website for each part in the kit. I just had my laptop with me as I worked on the dryer on all of the work progressed smoothly - except putting the drum back into the dryer. I didn't pay close attention to the video at this final point of reassembly. You need to watch carefully during the video how the technician is orienting/supporting the drum (i.e. how high he is supporting the drum while guiding it back into the recessed hole for the bushing on the back center of the drum). It was the first time I used this site, and I am incredibly pleased with how well the self-servicing went on my dryer. By doing the work myself I am sure did a few things more thoroughly than a service technician would have done because they are pressured to get to their next job as quickly as possible. I used my Shop Vac to clean out lots of lint, dust and other debris inside my dryer. I also cleaned and lubricated the needed areas for the Idler Pulley and Drum Bushing on the back of the center of the dryer drum. I also did a much better job of installing the Duct Trap Felt than what I found on the parts I removed. Also, I got all the parts in 1 Day, instead to the 2 days they quoted to me.
