Apparently that is the driveshaft where the two pieces come together (slip yoke) binding, not being able to freely move. When the grease is added, it can move freely as it was designed to do. All i can say is mine is still smooth and today i towed our bass boat with no issues as well.
That makes a lot more sense. I was thinking that the clunk was from looseness or play in the drive line and that adding grease would keep that from happening (which didn't sound plausible). But your explanation of the clunk being caused by a lack of lubrication and thus the binding makes sense. So in essence, the problem is caused by things being too tight rather than too loose. Thank you.
