Forgot to post an update on the seal leak.. When I finally got around to the seal leaking I drain the oil and the diff was half full of water.. I knew better than to not not drain that first thing so completely my fault. Since it sat with water in there for 5 months the growling noise has returned when turning sharply.. I'm at the point of IDGAF cuz it's winter I'm only using to plow my driveway now so if it tears itself apart so be it. When spring gets here I'll pull the diff put new bearings in it and maybe put in a torq locker.. But hey good news the new seal isn't leaking 😂
