Canadian Tire sells 75W-90 and 80W-90 full synthetic EP oil. Which ever is on sale and available is fine.

My front axle was weeping when the hydraulic oil was in it.
I drained the oil from 3 locations, and refilled it with 140W,,
a week later, it was weeping,, again.
I believe, even though I had properly drained the axle, enough hydraulic fluid was left to dilute the 140W.
I changed it again,, and added the 140W again..
THAT was the last of the weeping, it has been perfect since 2016,,

Hydraulic oil. It shares it with the HST and hydraulics.

If your tractor is like mine, your owner's manual says you can use gear oil or hydro oil. Any GL4 or GL5 mineral gear oil around the 90W should work just fine.
