It's a bent housing I've had it before!! Pull the knuckle look at were the axle sits in the seal and see how strait it is in the seal more than likely your gonna see a gap were of course oil just gonna run out when you lean the vehicle. Fix is get a chain and a bottle jack and see which way she needs to go back and work it slow then of course in the end put some new marlin seals in it cause the stock ones are trash!! Oh and then gusset the housing from doin it again!! If this is your problem there's the info
