It's most likely the lower seal is going bad.
There can be a couple causes for that.
One, and the cheapest one is that some grass and weeds got in above the stump jumper and wrapped around the shaft.
Two and the harder one is the lower gearbox bearing is getting loose.
If you get under the deck and can rock the cutter hear and hear a clunk and moves back and forth or up and down,
the bearing is getting bad.
One band aid fix that can get you several hours is to mix in half a tube or so of good grease in the gearbox the next time it is low,
then run it to blend the gear lube and grease.
It won't fix it forever but if the gear box level is monitored and refilled as necesary it can get through for a while till you tackle pulling the cutter head off and the gearbox off to replace the bearing and seal.
