I got a real good example of this concern in today and I show you guys. In this video I show what is causing it and just how to fix it. While this concern is well documented on the two piece drives hafts not much is out there specifically on the one piece drive shafts.

 

Coo-ul! Good job. Thanks.

 

Cool...nice video!

 

Nice vid sir, thanks for all your help.

 

def. going to try this ,thanks a lot

 

For all the money in warranty work for this alone, you would think Ford would simply drill/tap the spline section and add a grease zerk. Problem solved, serviceable by the customer, done and done. Thanks for another well done video

 

curious if not doing anything about the slip bump hurts anything.

all of our 2010's at work have this slip bump, most either don't notice or don't care so nothing is getting done about it (including mine).

any harm done if the slip bump never gets addressed?

 

most of the truck owners these days would forget to grease the driveshaft or complain that a modern truck still had a grease zerk on it.

 

Mine makes more of a "click" than a bump that you can feel. I figure it's probably the same thing. Any thoughts on the correct grease to use if you don't buy the kit from FoMoCo?

 

Hi All,
Mine has done it for the past 2 years its a 2012 does it on Stop and Go the dealer says the service bulletin is for the 2 piece shaft,I mentioned to them about the nickle plating on drive shaft side of spline and having to use the teflon based grease on it,the service writter said that if i know the problem that i should fix it, needless to say we had some choice words and i never will deal with there Stealership again i have bought 6 vehicles from them through the years,time to take it to a dealership that gives A

 

What's the current mileage on your truck, ecoboost12? If you'd like, I'd be happy to get you a list of other dealerships in your area. Just send me a PM with your ZIP code and I'll do the rest.

Was looking for info on my 13 SCrew, but found this for my 07 R/C ! Here I just figured that the spare was low and moving back and forth, but this sounds exactly like what I'm feeling! Great post, teflon grease, here we come!

 

Hey fellas,
Purchased my truck new 12-28-2013. On 7-28-2014 I took my 2013 F-150 Screw to the dealer for transmission clunking. In stop and go rush hour traffic, it clunks between 10 & 30 mph. The dealer applied a transmission Technical service bulletin to the PCM/TCM (Powertrain control module and Transmission control module). I was told its a 'learning' transmission and the clunk would get better... NOT!

Sounds like the 'slip bump' issue would fix my truck as well. Great video and information.

Adios.

 

I'd imagine it would wear to a point it will have enough play in it so it doesn't bind, or to the point it would break something possibly? Keep us posted Mike

 

My 2011 has this. I greased it about 2 months ago but I didn't use the teflon grease and its back. I just ordered some teflon grease and will do it again.
