Kubota BX, Replace Front Axle Seal trouble spots.

After 3235 hours, I finally ordered and installed new front axle seals on my 2010 BX25.(JUNE 13 /2024) The oil has never been changed since new, and the oil level was below the axle tube, just in the hubs.
So far, I added a US quart of 80-90 W in each hub vent, which added about 1/2" of oil in the bottom of the axle tube. I added another US quart to the axle tube, and today I will run it.
