After three years and alot of visits to Ford they finally repaired and greased my slip yoke,this time I brought some proof from this web site.It turned out I bought some marine grease with teflon 2-4-c which I also found here and went down to Ford and told him what I found here (10-22-6 & 09-25-5 tsb's)he said no problem do you want us to do it now and I said yea sure.Turned out he was dead serious,I may have caught him on a good day.I said I bought the grease because I was going to try it myself,he then said do you want to watch him do the job.
It took him under 5 minutes,he said he tells customers to do it every 30,000 miles.I asked how much if I had to pay for it,he said $60.00.
I'm not saying all dealerships will do this,but it's worth a shot if you have the TSB'S on the problem.
------------------------
The TSB related to the driveline clunk is 10-22-6 it replaces TSB 09-25-5. The TSB is strictly for 09-10 F-150's built before 12/01/2009.

 

Awesome! I bet it's a lot more peaceful now.

 

That's one of the first things our shop does when a customer comes in complaining of a clunk on start up and stopping with a slip yolk drive shaft.....

 

--------------------------------------------------------
I think I'll keep the truck until a new body style comes out,unbelieveable took less than 5 minutes and $10.00 for the grease.

 

So far everything is holding up.But I still think and wait for it to come back at every stop sign or red light,The doctor at the ford showroom said I may have post tramatic yoke sydrome.
It's a condition alot of ford truck owners are getting,he said the only way to get better is to trade it in.

 

Was the grease inside the splined portion of the slip yolk, or was it outside on the shiney smooth part?

did they do anything to clean rust off the splined portion?

 

just had mine done as well I think they put some kind a washer in to, the part was back ordered a month and a half but all is good now

 

I had mine done a couple weeks ago. Took it in told the service advisor of the clunk. He asked a few questions, which most I don't do so couldn't answer. They greased it and all is good.

 

Ford isn't the only one with this problem. Chevy is having it on several body-styles and power-trains in the silverado, tahoe, and suburban. First we use the grease, if it comes back we have to replace the slip yoke with a new one that has a special nickel plating and yet more grease. After the replacement they don't complain anymore.
