Water seemingly leaked from the top left area of the machine... trickling down and gathering in the middle of the front counterweight... then to the bottom chassis eventually to the floor.
I thought out of an abundance of caution to replace not only the tub seal (most likely culprit) but also the hose and seal from the detergent compartment while everything was open and exposed.
Followed the replacement steps (used a few different videos to get other opinions and tips before I started). Went quite easily actually... was a bit enjoyable actually. One thing most videos don't mention is the tube at the top of the bellows/tub seal (maybe an airline to prevent vacuum? not sure what it's for)... you have to pull the black hose off the white connector, pull off the white plastic washer then the part that is exposed to the inside of the wash area can be removed.
No leaks... tub can still shake like a son of a gun depending upon the load but I know I can replace the shocks... adding that to this order would have made the repair price 1/2 the price of a new washer... couldn't bring myself to do it at this stage.
