I'm pretty sure the bearing and seal kit you're after is the same one as a Whirlpool duet, like the wfw9200. Bearings are 6306 and 6307. If you get a knockoff kit, the seal will most likely have the dimensions on its pouch. If you get authorized parts, it won't. Fwiw, it doesn't really matter because if you need bearing replacement you need a seal. If you're repairing dozens at the lowest possible cost, and can source a super cheap seal in bulk, it might make economic sense. I wouldn't bother.
