Product review (5 stars): Seal repair
Worked perfectly to stop the leak. Saw some questions so here's my expierence:
You put the seal all the way down on the shaft. Don't forget the grease.  As you tighten the bolts back to the under side of the tub it will fit tightly in the tub opening.

Did have trouble with the agitator bolt.  All videos just said to remove with 7/16 socket looked so easy.  Ha, this bolt was not breaking loose.  Had to use impact wrench!
Tub removal: super stuck. Used wood across top under lip and beat it with a hammer until it broke free.
Spanner nut: did not want to buy spanner wrench for one time use so I used a chisel.  Placed it in one of the notches, side of the chisel blade and tapped with a hammer on opposite side of the chisel blade.  Worked my way around and it came off easily.

Recalibrated after reassembling according to tech book located inside cabinet.
Appliance pros has step by step video available for this repair.

Pretty sure the small leak affected the bearings. In my washer,  amana top load, you have to replace the entire gear case for a cost of roughly $200. Not worth it.

Also replaced shift actuator. Assuming leak caused it to fail.  Very easy repair.  Symptoms of that were not always advancing to spin and lid lock releasing during spin cycle.
