Replaced inner and outer tub bearings, plus the tub seal. It's about as far into disassembly of the entire machine as you can get, but if you're looking at buying bearings you've probably come at least part of the way before already. Nothing about it was especially challenging. Just dedicate the garage for a couple hours. The bearings did not appear to have a front or back to them, they appeared to go either way. The tub seal did have a front and back, so pay attention when removing the old one. In my case the soap scum made it clear which side was the wet/water side. Do not reassemble the bearings and tub (spider arm) shaft with added grease. There is a small weep hole in the tub bearing recess where the bearing goes that allows water that gets past the seal to drain out. If you add grease, water that gets past the seal will become trapped in the void between the inner and outer bearings and corrode the tub/spider arm shaft. OK to add a little grease around the edge (perimeter) of the bearings to facilitate them sliding into place during assembly. Got the machine back together and my wife was eager to run a load of laundry. The machine was so quiet that we'd forgotten it was running (laundry room door was closed out of habit from the previous growling).
