I've got the "clunk"
Kinda sounds like an STD... 
I bought the PTFE grease from Ford but have since found a few guys that installed grease fittings.
Thoughts? Has anyone here tried this?

I didn't find any long lasting success with anything but the Ford grease, and it doesn't come in a grease tube. I never really had the clunk until I got to around 190K miles and that was with several passes down the 1/4 mile. I tried the "red" grease a few times over the next 25K but it would last a very short time and start clunking again. I just did the PTFE grease last weekend and it hasn't clunked a bit since.

Hey Tim, it just started about a week or so ago and I have 109k on it. It has had a gravy life, no pulling just driving and grinning.

I read another thread where an f150 owner did the same thing. I'm not sold on it mainly because I'm not sure how it would affect the balancing of the shaft. I have to say it would be nice to hit it with the grease gun tho.

We did a lot of them in the fleet but found out the regular tube grease would not last very long. As for location we just measured a older shaft on a F250 that came with a zert installed and put them in the same place. Never noticed any balance issues.
Not very scientific but it worked.
By the way some of the aftermarket replacement yokes come tapped for a zert.

What we did was remove the yoke from off the shaft and drilled and tapped. We did however locate the hole in a grove. Do not know if it really made any difference or not.
Just thought it would give us better grease flow/spread. Also a little less drilling.

Well I went ahead and pulled the shaft out of the slip joint. I'm not sure what they used from factory but it sure wasn't the PTFE grease I put in it. Perhaps the PO had it greased. It looked like plain bearing grease to me.
Anywho it's done. I should know this week if that was the fix. I will report back...
Thanks guys!

Subscribing, I have a little clunking action going on too , I thought it might be in the slip joint but never really tried it, I'm going to now
That clunking makes me feel like I'm in a Dodge

I've got the "clunk"
So far so good this morning, but it may be a couple of days before I know for sure. It doesn't clunk all the time.
Here is a picture of the Motorcraft grease, and the cutters I used the crimp the boot clamps.
It was a very easy process. Expand the boot clamps with a screw driver, remove the 4 bolts at the rear diff, and slide the shaft out. Clean, grease and reinstall.
