Like I said, purge the old grease, meaning you see it (the fresh grease) coming out from around the seals. This is the only way to know that all 4 journals are getting new grease, and that the old "dirty" grease is out.
If it's not coming from around all 4 seals one or more grease passages are blocked. For as cheap as the u-joints are, if that's the case, I would just replace it.
I'm attaching the relevant section from the Spicer manual on greasing them. (I've seen a lot of misinformation about it on various forums)
You'll notice that it says every 5-8,000 miles, but I tell people "every oil change" so it just becomes habit, rather than having to remember, or take notes, when you did it last. Obviously, if you're off-roading a lot in water or muck, you want to do it more often.
One last thing, you
must lube them. If you don't do it properly, you're better off with sealed u-joints.
