The front axle seals on the final drive for my 2016 John Deere 1025R were leaking pretty bad. I decided to completely disassemble one of the final drives to really clean it and learn how it works.

My seal part # is TR109398

If you have a very very early 2016 or earlier tractor your part # is probably LVU802855. If you have a newer model, I don't know what your part is.
