I brought this to my local dealer and they wanted to charge me $100 plus parts which total up to around $30. Does this sounds correct? He said these parts are not covered under my power terrain warranty. My truck is a 2011 with 40k miles.

Just brought my truck in for 45k service. I reported same klunking noise and dealer told me there had been similar reported problems due to the spline on the 2 piece shafts. Without even a debate, they said its covered under the power train warranty (engine to rearend differential) and not to worry they'll take care of it at no cost. Entire new shaft on order, I'll be taking my truck in within a couple weeks. I guess it really depends on the dealer you have, luckily mine has always been cooperative and upfront

Thanks for the info. I'm going to try and push it a little harder next time. Why do you think they are replacing the entire shaft rather than just performing the TSB?

Not sure why they would replace the entire shaft vs. replacing parts per TSB. I figured if I can get the whole assembly for free I didnt want to ask. This dealer has been very cooperative. IMO It almost seems as though they get reimbursed through Ford for the warranty work, so they probably take it to the extreme to "overbill" on labor and material.

Any suggestions for fixing this for a truck that is out of warranty. Truck did it sparingly first 50,000 miles, but now has become more pronounced. almost every full stop has a clunk now. truck is 61,000. Go figure. Thanks!

also, any risk of damage to the truck if left unresolved, or is this more of a nuisance?

after feeling this in my 2002 scab, i am as confused by all the answers as i was by the initial problem. I had seen a few photos of grease fittings and thought, great my monkey handed self can do that much... but being in the city, i am not able to take apart things and do this after finding it was a mod and the parts needed to be taken apart

my question is, and has not been answered EVEN by the tsbs is the CAUSE... granted im an almost idiot when it comes to mechanics but this is what i think is happening... the spinning of the drive axle with the ujoints causes a torsion flex upwards or sudeways which is pulling on the spline? this is the slip and the flex is the thud? meaning its not actually hurting anything its just sliding a small amount and then going back. i imagine the lube is acting more as a cushion than a lube, hence the breakdown. i have seen and cant remember where that a shim was put on and it stopped it. for my part, tge concern was something broken, which if after 12 years is something that is still happening is not as worrisome as just annoying. having a few moving parts going from a dead stop or vice versa without any noise or vibration, would be awesome and would probably mean we were in ferraris not a truck. but then again my truck isnt worth 30 grand+

Hey Spark Monkey, Are you still having the clunking issues with your 2014?

Bumping this thread.

I have a 2007 long bed 2WD with a 2 piece drive-shaft. I have the clunk, gonna try the zerk fitting method.

I looked up the price of a complete new drive-shaft, which is $511.00 from rock auto.


Is the actual re-greasing of the drive-shaft work, or do I need to drop $500 on a new drive-shaft?

This was a problem on the Ranger trucks as well. After years and years of this, why is Ford still having this problem?

My '13 F-150 Supercrew clunks just like my '03 Ranger did when stopping and taking off. Yes, greasing the slip yoke stops it for about 10,000 miles and then it comes back. I guess Ford's tolerances on the splines suck because Jeep and other companies have been using slip yokes for years without this issue.

Ford isn't the only one with this issue. GM has the same problems as well. I had a chevy 1500 that did the same damned thing. Length of shaft also accounts for some of it. Jeeps have very short shafts compared to pickups. They also tend to have more travel than pickups. The simplest fix is to tap in a Zerk fitting and apply a shot of grease every so often. The downside is, if grease gets into the transmission, it can cause seal failures.
