Product review (5 stars): Cheap/easy solution for horrible noise!
Product works great so far (2 weeks since installation), fraction of cost of Maytag part ($90+) or other online appliance parts stores ($50).
My washer started making a horribly loud screeching, grinding noise during the spin and rinse/drain cycles (i.e. whenever the tub is spinning to get rid of water).  From what I researched online, I thought it might be the drain pump.  First, in order to move the washer around in order to access the back panel, I unplugged the washer, and removed the drain hose from the wall (you have to pull the last part of this hose out in a spiral fashion so as not to break the tabs at the end of it).  I didn't have to turn the water off and disconnect those hoses since they're long.  I opened the back panel, took the hoses off the pump (have a medium plastic bowl and rags on floor to catch lots of water), and unscrewed 3 screws.  Then you have to move washer and tip it back in order to get under and take off belt - it helps to have a heavy block or something to hold washer up as you tip it back - be careful it doesn't drop on you.  Then put it down, & go back to the back panel and simply lift drain pump out.  I noticed that the metal sleeve on the bottom pulley had come out in an uneven way.  When this sleeve comes up and out it grinds against the bottom of the pump during spin, and makes that horrible noise.
I put the new pump in the hole (don't screw it in yet), tilted the washer up to put the belt back on, then went to the back panel again to screw in the new pump - this part is tricky because the belt is designed to be really tight, so pushing the new pump into position to lineup the screw-holes will be difficult.  What makes this possible is the fact that the motor actually is designed to move a little from its housing towards the drain pump in order to screw it in - when you're under the washer, you'll notice that the screws under the motor glide along small tracks, back and forth.  So after a little trial and error, you'll screw the new drain pump back in, connect the hoses with the clamps (put the clamps on the pump first, then slide the hoses on) and clean up.  Don't put on the back panel just yet b/c you'll want to safely (i.e. from an appropriate distance) look at the drain pump with a flashlight when the washer is on and in spin/rinse mode to check for leaks.  Of course, before you can do this, you'll need to reconnect the drain hose to the wall, plug in the electricity cord, and turn the water back on if you turned it off.  If this is your first time doing this, it'll take about an hour to be sure you do everything safely and carefully as not to break things.
So, with shipping costs, I spent $24 on this part instead of a $130 service call from Sears Blue Crew or the Maytag Authorized repair crews, who would've also charged about $100 for a new drain pump, plus tax.  Thus, altogether I spent $24 versus around $250!  Gotta love the internet!  Good luck!
P.s. when checking for leaks after installation, I did see some water drops, but turns out they were from the water hose at the top of the washer where it connects to the flume which channels water into the tub.  The clamp there had become rusty and needed to be replaced (I also replaced the flume as well just to be safe - and it was cheap).  But that's a whole other story!
