Back after a while.

I own a Kubota B7800 that keeps my property running About 700hrs now with a full service when I bought it with 420hrs on it. I heard some noise from the front end, found some swirlies in the oil (UDT2 with 200hrs on it) and came looking for common issues with the 4wd front end, I pulled the left final and disassembled it - and all is well. It's looking like I'm pulling the right final tomorrow and the tube/front diff if there are no issues with the finals.
Anyone with experience with a similar, please let me know your findings.

Welcome to the site. It’s fairly common for the front axle lube to look pretty trashed with normal use. I can’t remember what the change interval is on mine but I changed it early. I’m glad I did because it looked bad but it’s apparently normal.

For front axle noise, look at the shrouds around the drive shaft first - mine was loose and making noise. Lift up the wheels with loader and turn then - should be able to tell if noise is coming from the wheels or further inside.
