How to dismantel a A7309 maytag to replace agitator seal

Maytag A7300 washer. Probably a good ten yrs old. Was bought used.

Water is leaking out the bottom around the center tub drive.

(The water comes out while filling just above the transmission.)

My assumption is that it seems to be the tub spin seal that is wore out.

How do I dismantel the machine to replace the seal?

Or is it the tub seal that is leaking?

What ever the problem, how do I take it a part to fix the problem.

Thanks.
