2013 John Deere 3320 hydraulic oil front axle change #John Deere #hydraulic oil

This is a hands-on, first-time DIY walkthrough of changing front axle hydraulic oil on a 2013 John Deere 3320, including set screw locations and sizes, how to relieve cap pressure, the struggle of actually pouring oil into the housing, and settling/recheck timing. It also covers a lesser-known detail: these units lack an air vent, which can cause pressure buildup and seal damage under heavy use. Best for owners doing this specific job themselves.

Appears to be an owner-operator documenting a maintenance task on his own tractor for the first time, not a professional mechanic or dealer.
