Product review (5 stars): These fixed my washer!!! Read special instructions inside-it will save you $ and tools!  You do not need to take tub off!
Go to youtube and there is a great repair clinic video: "Drive Tub Wear Pad Replacement (part #285744)".  Take special note, please read this.  YOU DO NOT NEED TO TAKE OUT YOUR TUB!!!  You don't need any special tools other than a flathead and philips screwdriver and a 1"piece of wood.  Once you have the sheet metal off and folded down, just pry the bottom tub frame up with a flathead and put the piece of wood in as a wedge while you snap out the old pad...you might not even need that with two people if you flex the tub away you. You will see exactly what I mean when you get the sheet metal off.  There is absolutely no reason to remove the whole tub assembly to replace these pads.  It is a 10 minute job from start to finish...maybe 20 if you take your time and it's your 1st time around.
