For reference I'm getting the clunk when I let out of the clutch in first or reverse unless I let it out very slowly. I'm trying to figure out if it's a u-joint issue or the slip-yoke needing greased or something. I'd rather try the u-joints first if there's a decent likelihood that it's the issue.
There should be no play
