Chris K Flagstaff , AZ November 25, 2021 Appliance: Whirlpool Washer WFW9450WL00 Whirlpool Washer Wfw9450wl00: Bellows was very torn previous owner washed something nasty in it hoses were gross. How to replace Bellow Tub Seal. Basically, disassembled entire unit and cleaned it, plus sanitized the drum. Changed the hoses and bellows. The bellows was a bit of a challenge. The drum clamp was difficult to install. I should have left it for a Saturday project instead of a weeknight. Not a difficult project, just time consuming getting everything stretched into place.
