You have a worn knuckle seal at least. you can keep pumping grease in the top and wiping it off the back and give yourself a little more time, but meh, just get in there and fix it. My $.02.
Good idea to open it up and check things out regardless if you havent been in there in a while.
It looks fine, just zip tie the grease reservoir (square plug atop the knuckle) every so often to see how much is in there. Then you'll have greasy zip ties in case you ever need them.
