Luckily happen to be walking by when machine started to make "grinding" noise as washer tub started to hit plastic tub. Assuming by shutting down machine, prevented any more damage. Aside from noise, when we opened door, tub appeared "crooked" tilted back a lot further then normal. When we removed the rubber door seal, could spin drum and hear and see the wobble and grinding. Internet told us the possibilities and so we proceeded to break down the machine. A drill with Philips bit and socket driver adapter makes breaking machine down exponentially faster. (Some good pics as you go and Dixie cups labeled for each all the screws also helps)... Hardest part is getting tub out, it requires two people as one needs to support tube while other undoes support springs. After that unscrewing tub and to get to Spider and shaft was easy. The arm was broken in two places. Also order the six bolts as they also will be destroyed. Part were here in two days (with regular shipping and delivered on a Saturday!!, appliance partpros were amazing). We used water proof grease (found by faucet repair in your box store, get at least 2 containers) to lube new shaft and rubber gasket when putting tub back together, also took opportunity to do complete maintenance, lube shocks, we cleaned out all the drain hoses, sprayed all connections with contact cleaner, etc... (The machine will be stripped down to just the metal frame.) Then two people to put tub back in and then its a one person job after that. Hardest part was actually getting bolt thru shocks lined back up, due to angle inside machine. All in all, about hour and 20 minutes with some time spent figuring out what screws went where.. (you think you will remember, but you won't)... need to label for sure... Machine works like new, no noise, no vibration, perfect...
