How to Troubleshoot & Replace Whirlpool AP4557873 / W10324651 Drum Mounting Hub

We replaced the tub seal. Repair probably took longer than needed as the hub & drive block assembly had adhered to each other due to detergent and mineral accumulation. Nothing a wire brush and some penetrating oil couldn't handle, though. While replacing the seal required a near complete tear-down of the washer, I have to say it was not a difficult repair. Highly recommend spanner wrench sold on this site (TJ90TB123A) for this project. 

Followed directions on you tube video from parts pros com. 

Researched problem and found that transmission bearing was bad and the tub seal was leaking which caused the bearing failure. I ordered the transmission, tub seal, drive block assembly, splutch assembly, drive belt and wash plate bolt. I replaced the other items because of the age of the washer and I already had them off to replace the transmission. Everything went smooth on the replacement after I watched the videos relevant for the repair. The biggest issue was the drive block because it had corroded. I used a dremel tool to cut it into to remove. I did purchase a spanner wrench to remove the basket drive spanner nut, $13.00. Did the recalibration per instructions and washer is now quiet and no leaks. Great videos. 

Replaced gear case and drive block kit. Removed lock nut as explained, Then, had to cut and split both components to get them off the shaft. I used a "Dremel" rotary cutting disc tool to cut into the components to make cracking the parts with a chisel easier, as shown in the video. I followed the Appliance Parts videos for the gear case and the drive block kit. Other company's online videos did not show how to remove the ceased corroded parts. Note: using a scraper under the flange cut the molded plastic anti-slide blocks under the flange. I cut shallow grooves into the basket at each block and put slow curing "JB Weld" epoxy onto each block location before installing the flange. The epoxy filled the block spaces and squeezed out as I screwed the flange in place. 

Replaced suspension kit and drum hub and this fixed it . 

Replaced tub seal. 

I bought two plastic drum mounting Hubs because that is the part I had to replace and they are only lasting a couple of months. Your parts list did not give me a metal option, but I found this one and it fit perfectly on my Maytag Washing Machine. The installation was a little different than the Plastic Hub because I needed to buy a spanner wrench to tighten the new metal hub. It was quite easy and has been going about 2/3 weeks without any problems. Right now I have my fingers crossed but it seems much more stable than the Plastic and is working well. 

Replaced the drum mounting hub. 

Replaced it. 

I took it apart and reassembled it after watching appliance parts pros video, it was very helpful.
