yea warn lubricates the internal compenonts and suppossedly thats good enough for the lifetime of the part, unless you pull it out and clean them really good, but they sell rebuild kits for them with grease... however the outside of the assy i dont see why you couldnt grease it up a little.. definitely cant hurt for corrossions sake..
