That's it. I've been in mine so many times that I just use zip ties to hold the boot on until next time.

Do you just wipe grease on the spline or does the spline have to be separated?

Mine has been clunking for awhile

I would think to pull it and wipe grease on the inside and splines. Shouldn't need to do this every year I wouldn't think, but I don't live in the salt belt.

I undo the u-joint straps on the carrier bearing side and pull the upper section off so I can grease the splines (and the cup side). I use my fingers to slather some on there. It doesn't take much because any extra will be pushed into the cup or out when you slide it together.


If you use this method you need to mark the shaft so that you put it back together exactly as you took it apart. If not, your driveline my no longer be balanced. I use tire chalk to mark a line across the joints so I get it all lined up. Yes, the shaft only goes together one way but once you disconnect the u-joint you can freely spin the shaft and the rear wheels (if it's not on the ground). If it's on the ground (CHOCK THE TIRES) it will not rotate on you (I know...duh) but an ounce of prevention is worth a pound of cure. It only takes a few moments and gives me peace of mind in case there's an issue.

PERFECT u da mannnnn....

do you need to remove the drive shaft from rear end as well. how about on the center bearing side. does that shaft slide out of bearing.. I thought it had to be pressed out.. maybe it would be a good time to take that , what the whole front drive shaft, to machine shop to have new bearing replaced.. what is best bearing for that a NTN or something else.

Actually when new there was a teflon coating on the splines which made for a smooth drive train. When it starts to wear off the clunk/bump starts. The teflon grease was Ford's solution in a TSB they released. I am guessing that was the fix for warranty claims but when out of warranty they probably recommend a new yoke.

No you don't. You only need to remove one end and the shaft pulls apart. You don't need to deal with the carrier bearing (yes, it is a press on/off deal) as that shaft section does not have a slip joint on it, only the rear section.


If you do replace it I'm not sure of the part number but I only use Dana Spicer or Ford parts on the drivetrain.

I still have all my teflon coating but seem to have been on the wrong end of the tolerance specifications during the manufacturing process. Hopefully the Ford grease will last longer than the others I have tried.

So I filled up a new mini grease gun with Ford teflon grease today and slid under there and pumped in about 10 shots. Went for a drive and smooth as can be, took all of two minutes. It's been almost 3 years since I installed the zerk and today is the first time I've used it. When I installed it I took a worn, rounded grinder wheel and cut a groove all the way around the splines so the grease could reach them all.

thats cool.. does the grove you made match with the zerk fitting by chance?

how hard is that metal. did you wrap tape around the shaft to get a straight line and grind it that way. was it on the truck or on the bench..

why does ford not do this from the factory.. make better sense to me.

I did it freehand on the truck. It is in line with the zerk when the truck is unloaded.


Some of the old Fords did have a zerk there. Ours are new and improved.
