Well you must have some other issue or bad part, IMO. When I did mine on 12/2016, I used the Blue Ford stuff and I now have 89K on the truck and its still clunk free.

Sounds like you have a bigger issue, I say that because most folks who did the lube initially, at least got some temp relief with the repair not lasting long.

Good luck!

I appreciate all the replies. I feel absolutely 100% confident that the clunk I am hearing is the slip yoke and I don't know of any part that could be bad or be causing it other than the slip yoke itself. I think the mileage on my truck and possibly the lack of attention to detail/proper procedure when I had it lubed are why I didn't really see any improvement. I truly can't say that I didn't have any improvement whatsoever when it was lubed. It's difficult to measure if one clunk is better or worse than another. But I do know it did not go away altogether for any amount of time. As mentioned previously, I felt it leaving the dealership.

I don't think Ford's PTFE is necessarily snake oil. There are enough posts and threads out there to show that it seems to be the longest lasting fix the majority of the time. But I do not think it's a permanent fix.

I've read so many posts about different "fixes" that it's ridiculous. I even read on one forum that someone's dealer replaced their one-piece driveshaft with an "updated two-piece driveshaft and slip yoke" and that this cured the problem.

I've ordered the Neolube so I'm thinking I'm going to try it and see where it gets me. If it doesn't solve the issue, I may try a new slip yoke. Maybe a new slip yoke AND Neolube, lol.

When I did mine, I cleaned both parts well from all of the old residual coating. I then lubed the internal trans side,from the edge to the top and all around. I then took some additional Ford product and placed a thick layer all around the end of the inside of the female side. I did this because I had read how once you start to slide the spline in, it forces the lubricant to the top and cleans the splines of lubricant. This would ensure,hopefully, a full coat.

I then lubed the male spline part and slowly inserted. Felt like a new truck and knock on wood,still does.!

Good luck!
