How to Troubleshoot & Replace Whirlpool AP6008773 / WP37001042 Dryer Drum Support Roller

Found this site, watch videos on how to disassemble and repair. Then, disassembled to check on what was needed. Belt was frayed because of a seized tension pulley. Then, I reassembled so it could be used until parts arrived. I decided to do an "overhaul" of all the parts that can wear out including belt, tensioner pulley, drum support rollers, drum glides, and glide felt pads. I figured that, as long as I am taking it apart, I might as well do it all. The parts arrive in 3 days. So, I disassembled the dryer again (easy job), replaced all the parts, and reassembled. I wish I had brought the tensioner pulley bare instead of buying the entire tensioner assemble. I thought that would be easier, but the blind nut used to attach the assembly is nearly impossible to get started during the reinstall. Small hands are needed. The dryer works like new now. Spend $65 instead of $750 for a new dryer! The videos and information on this site made all the difference. They tell you exactly how to fix it. Even opening the top of the dryer is a mystery until you see the video. The putty knife trick is a life saver! I'm a VERY satisfied customer. 

Bought new rollers and tensioner roller. Replaced all three and it works well and is quiet. 

Replaced bad belt tension pulley. Replaced belt,drum support rollers, felt and glides as preventive maintenance. 

Replaced the drum rollers and tensioner roller. When I dis-assembled the dryer I discovered the drum sliders were worn out and had to re-order the drum sliders. On receiving the drum sliders, I re-assembled the dryer and tested. I would suggest taking the dryer apart before ordering parts. Parts were delivered overnight, very good service and they were the right parts! Thanks. 

Opened the dryer, found front drum glides gone, looked at the blower fan, the hub had removed itself from the blower wheel. I decided to replace the idler pulley and rear support rollers. I ordered parts on Sat got them on Wed. 2 hours of time removing and replacing parts $60.00 & I have a sounds like new dryer. Thank you APP for the killer videos showing how easy it is to fix it yourself..!!! 

Replaced drum rollers 

Replaced drum rollers, belt and tension pulley 

Installed new tension pulley, and belt. However, the drum rollers were mounted differently than the ones I received because the originals are permanently mounted on the axles.So it is necessary to order both the axles and the rollers. The video was useful. 

Used the videos in appliancepartpros.com for reference and repair went off with a hitch. Saved 50% by purchasing the parts online instead of locally as well. 

My wife called a repair guy out AND paid him $130 IN ADVANCE to repair the dryer. That was 2 months ago and the guy hasn't returned a sigle call. He did call our home once and leave a message saing that the idler pulley was "on back-order". After some research, I ordered the parts from you guys, with my wife asking me the entire time, "You're sure you can fix it, right?". I assured her it was an easy fix and that I wasn't gonna charge her anything to do it. I went ahead and replaced the belt and the rear drum rollers, in advance of any problems with them. It took about an hour to do, minus clean-up, and was pretty straightforward with no surprises. I just wish she had asked me about it BEFORE she called someone.
