Try putting an all-16ths wrench on the piece under the zerk and snugging that back up. I think the socket in the spider is threaded, making it kind of a 2-piece fitting...I think. I've only had to do two ujoints on mine. The last one I bought was set up, and it's been too long since the first for me to remember.

I had issues in that spot on my front driveshaft. When it was built, somehow that block got knocked loose and had to be tacked in. Ran that way for years, though, before it sheared out completely in a pit somewhere the summer before last.
