F150 Driveshaft Spline Lube

In this video I remove my driveshaft to lubricate the slip yoke. My truck has been making a typical F150 clunk when I let off the gas and apply again at approximately 50mph, I hear a clunk on the drivetrain. Once I re-lubed the driveshaft splines the clunk went away.

Would like to support the channel?

Thank you! My son and I just did this today and now my F-150 no longer has the clunk. We needed to put a little penetrating oil to free the drive shaft from the differential but it was a great learning experience for my son.

Thanks for the video. Just greased my driveshaft. No more clunk. Spline was dry. Probably never has been done. Truck has 240, 000 kms.

Thank you! That's bump has been bugging me for YEARS! Will be doing this soon.

Worked perfectly, thanks. My mark to know which hole lined up where got washed off with the wd40 to unseize it but it went back fine regardless. Seems to have completely fixed the minor "clunk" issue.

Did the same thing on my 2019 f150 with same lubricant and it worked.
No more clunk. Thanks!
I also subscribed.

76 lbs is the tour we spec for those 4 bolts

That clunk for me was a the loosening of the preload on the differential bearing and the backlash feeling/sound that was associated in the driveline.

Great video keep in mind 2024 Ford no longer uses blue grease it’s white now 👍🏻

This is a great tutorial video... Thanks for the info.

I did this on an older truck without ever jacking it up.

I wonder if just regular grease will do the same job?Thanks for the video I've got the same issue & will be doing mine soon.

That's not the transmission is the transfer case where the slip yoke goes in to.
Thx for the video

Fantastic video thanks for all your help

keeping it aligned in the correct orientation is critical. as you know, these shafts are balanced. make a line with a paint marker. both ends. and dont use brake kleen. theres a coating on the splines. wipe it out. 👍🏻

You might want to spray the underside with a lanolin rust inhibitor like Surface Shield or Wool Wax etc to stop the rust and save the frame.

I replaced my driveshaft and marked it but the mark worned off by the time i got a new drivershaft 😱. How will i know where it should be without further damaging anything?

I have an 05 supercrew 4x4. This started happening..and before I knew it, my driveshaft broke in half while I was sitting at a busy redlight! Fix these.

How long did this grease last before the clunk returned? Or is it still good?

[robertclymer]

Yep, my 2015 F-150 has had that bump thing going on for a while now. I was thinking a bad U-joint. QUESTION? Is there any grease fitting on the U-joints or is that F-250 and up? Thanks for you video! Will be doing this SAP. Cheers from Michigan.
