How to Troubleshoot & Replace Whirlpool AP6009858 / WP6-3129480 Dryer Drum Roller Axle

Problem turned out to be the Belt Tension Pulley. So, replaced Pulley and Idler Pulley Arm and while at it replaced the Idler Spring, both Drum Support Rollers and Roller Axles and the Dryer Drum Belt. Also did a thorough vacuuming of the lint that had accumulated over the years. The videos on the website of Appliance Parts Pros, are excellent in the detail of the repairs. 

I just followed the video instructions and it really helped . I did fix it and it works very smoothly. Thank you . 

New tension pulley, drum axle and drum support rollers. 

Changed the two wheels and the two front slides and now there is no problem 

After watching the DIY videos, I was able to disassemble the dryer and locate a few problems. My blower wheel was stripped and spinning freely on the motor shaft. In fact, it had made contact with the housing and was starting to melt that plastic from the friction. I also decided to replace the tumbler bearing kit and the dryer drum belt due to wear. I also found the tensioner was stiff from old dry grease. I disassembled it, cleaned it and re-greased it. I replaced the belt since I had ordered a new one and the old one was frayed a bit. The only additional cost to me was buying a pop rivet gun and slip ring pliers since no one nearby had either tool to loan me. Finally, their telephone support was great. They helped me by phone to troubleshoot the tensioner issue. Overall, very satisfied with the experience! 

Replaced both drum roller supports and the belt tension pulley and roller. The video was very, very helpful. However, two steps were missing but I was able to figure out without the video. There were two additional screws at the bottom of the opening that needed to be removed in order to take it off and there was also one additional wire that needed to be disconnected. I did have trouble with the ring clip removal but eventually got them with a screwdriver. The repair would have been extremely quick had I not done a very thorough cleaning inside the dryer. Everything was wiped down very meticulously! I attempted to replace the dryer drum roller axles, but was unable to loosen the bolt and had a hard time accessing the bolts. 

The rollers and the axles were shot after 15 years of trouble-free use. I watched a video on how to disassemble the dryer, and replace the part. Total time (after I got all of the tools needed) took about 20 minutes to do both idler wheels. 

Appliance Parts Pro web site gives suggestions about what the problem might be. My problem at first tub rollers, one stuck other loses. Replacement of rollers fixed some noise then found fan blower loses on the motor shaft, with speedy delivery APPro send the correct part and I was up and running right-a-way! I recommend Appliance Parts Pro for the best price, parts and fast delivery, you can count on them. Sincerely, John (very happy). 

Replaced drum support rollers, drum roller axles, drum belt, and belt tension pulley. Used the AppliancePartsPros.com repair videos that made the job very easy. The videos were exceptional. 

I ordered parts from Appliance Parts Pros... because I was taking the dryer apart, I decided to order several of the wear parts and replace them as well. I disassembled the dryer, starting with the front cover, then the front bulkhead. I was careful to document what screws went where and where wires that I needed to detach were connected removed the drum and cleaned the interior and all parts by vacuuming and wiping. I replaced the tension wheel, the idler shafts, and the wheels. Then I replaced the drum front bearings and inserted the drum with a new drive belt in place. This was the trickiest part because it required the drum to be partially out of place to properly position the belt around the motor drive wheel and the spring-loaded tension wheel. What I missed initially was the importance of doing a final positioning of the belt closer to the correct position on the drum before doing larger spins of the drum. Once I did this correctly, everything worked great!
