O.K. Here we go...
First off, please excuse the quality of the pictures. I pulled these off the online manual for your washer and the pictures were awful as all Maytag did was scan the original manual and not care about quality. They should give you the idea. I scanned data from pulling the tub cover to doing the bearing.
Several things to remember:
First: the new stem and boot you'll get will not be the same as the old one. Like Dan and I said, you can use the extra seal shown above (It used to be the seal that came with the old style stem...) by installing it on the shaft and compressing it down with the new stem. It does help for a classier and longer lasting repair.
Second, use the Maytag tool shown for the tub nut and the stem. Borrow, steal, buy it. If you are serious about keeping this washer and/or working on any other dependable care Maytag, you should have this in your toolbox!
Third. When putting the new stem on the washer, I've learned to hand tighten it and then use the wrench and mallet to 'tap' it a little tighter. The set screw must not end up in a groove just as it will say below. If it does, you'll get a 'knock' as the washer agitates due to the set screw moving side to side in the groove as the tub moves.
Fourth. 'Dry' spin the washer after you're done. Twice through the final spin to help seat the new carbon ring seal on the bellows. Then wet test it.
Fifth (and most important). PATIENCE! Do the job slowly and carefully and you will have a greater chance of it working right the first time. If you think you will have a hard time remembering where things will go during re-assembly, get your digital camera and picture it before you take it apart!
Good luck and congrats on fixing a good washer that should serve you well and long!
