As pointed out in some linked AW threads while some oil (grease) leaking is normal to an extent, at some point machine needs taking apart, new seals, gear case cleaned of old grease, and packed with new, put back together....
Eventually water will start getting down into gear case displacing grease. That is the "leaking" of oil so famous. Also over time the grease simply begins breaking down and liquefies.
Maytag wringer washers were often overhauled after "X" numbers of years use. How often depended on many factors including how much/hard machine was used. Those in a commercial or other heavy use conditions would need attention more than one that was lightly used at home.
If you could post some pictures of your machine, and or at least give model and serial number it will help others lend assistance.
