A Ford tech's take on "THE CLUNK" (THE ONE and ONLY CLUNK THREAD)

[dataustin]

Five, a ways back I did the same thing to my 2011 Screw. I hope it works better for you because my 'clunk' came back after only 300 miles. For everything I love about this truck, the blend door actuator 'chirp' and the drivetrain 'cluck' are real downers. As to the blend door actuator, I am waiting for it to totally fail before I replace it due to the high cost. Of course, that will only be an issue of cab comfort until I get it replaced. Obviously, that is not the case if and when the drive train fails. Sometimes the 'clunk' is so bad I have to look to see if there are parts on the ground.

Who thought anything could be worse than the short length of the AUX wires? lol

For flip sakes...it better last more than 300 miles, lol.

I wish someone would video tape the slip yoke so we could see what is happening when the noise occurs. I really think it would answer the question of what the heck is going on. My original theory of it being caused by axle wrap is seeming less plausable. When the get re-lubed and the noise is gone shoots lots of holes in my theory. Something that may be happening is that daily driving the slip yoke will only move a small amount. Over time the grease will wear away in that small area. The grease would be pushed forward and essentially start to build up. If the truck then experiences suspension travel beyond it's daily norm it would have to push through the grease build up. Not having my Raptor yet I am obviously shooting from the hip.

This really makes sense... I've had my (new to me) raptor for 2 months now. It has 47,000 miles. When I got it it had no clunk noise at all. The past week I've been on a travel trailer vacation and I have been using a weight distribution hitch. A lot of you probably know that to install the bars, you lock the hitch on the ball and then raise the truck up as far as you can to make putting the bars in their slots easier. After I did this a couple of times (and the rear suspension of the truck was really stretching) I am now getting a clunking noise taking off at red lights. Almost feels like weight is shifting or something which is weird... Might just be my imagination.

Just thought it was interested to read this theory (my truck has been someone else's street queen daily driver until I got it and I JUST used the hitch to stretch out the rear suspension... Instantly getting the clunk.)

I guess I will try to get ford to lube the shaft when I get home (still on my vaca) does ford charge for this? I only have the powertrain warranty left...

May have figured it out.

I had my local dealer, replace the boot and grease the yoke-- no more clunk. It is more than likely a service issue.

Now, I am on to fixing my broken fuel door filler thing. I can not believe for a 50-60 grand truck Ford puts on a flimsy gas door with no cap? wtf FORD , what were your Indian born engineers thinking when they designed that chit?

The notices being mailed by FORD ref 11B25 do not specify which build dates are affected. I received mine today (GA). Presumption is based on the VIN #, FORD is mailing the notices to Raptor owners that may need a replacement drive shaft.

For those curious as to what the notice contains, if the administrators are OK with it, I will convert it to PDF and post it on Monday.

In talking to the FORD service technicians today, they told me they will replace drive shafts with part numbers: BL-3V4602-AB or BL-3V4602-BB. They made me bring the truck in to inspect it. If the drive shaft part number ends in AC or BC, you already have the good one and no replacement is required.

My drive shaft is now on order.

Ok guys... Clunk just started on my 2011 truck with 48,000 miles. I have the drive shaft part number: BL3V4602AB. I called my local ford and the service guy blew me off... Said that 11b25 is just a tsb and that there's very little chance they will replace my drive shaft. He said they would lube the yoke ON MY DIME... But that there has been no recall on my driveshaft. Carfax says my build date on my truck was 2/18/11 which is in the range people are getting their shafts replaced. What's the trick to get them to do it? Some on here say that 11b25 became a true recall but my ford dealer says that's not the case?! Let me know what's right and what's wrong!

If they won't swap out the driveshaft shouldn't the lube job be covered under my powertrain warranty?!

Took the truck in Tuesday and they are going to replace the drive shaft in the next week as well as a damaged tire with a sidewall cut. They say there are 350 drive shafts available. Wow! I don't know if that is locally, statewide or what.

What did you have to do to get them to replace the shaft? My local dealer said 11B25 is not a recall but only a tsb and there is little chance I can get my shaft replaced... He said best he could do is have the yolk lubed in my dime....

I have an existing powertrain warranty so I figured I wouldn't be running into these issues...

Against what many wanted everyone to believe, not every truck had this. I've got around 27k on mine, drive the **** out of it off road and have not a peep out of my driveshaft. If you don't have it, don't sweat it and if it ever appears, you know there's a fix for it.

Any ideas what I can do to push ford to replace mine? Seems like I qualify under ever detail listed on here... Year, build date, shaft part number...

Is 11b25 a real recall? My local ford service says no

Yep, got mine yesterday in the mail. Already had the fix done. I will give my service writer a buzz and let him know. He may need to see it again for a quik look to get his check from ford.

BDRAG

Any ideas on what I should do?

Thanks after some digging found the pics.

Strange thing for me I have the orignal drive shaft and build date of 3-11 but my VIN does not show needing this recall . Going round with service writer on it now . Will keep you guys posted.

My truck does not clunk bad now , but feels a little loose especialy over bumps. My thinking is to get this updated taken care of now and not wait . Will keep you guys posted . Any thoughts on this ? Would you go after it ?

Did you ever get yours fixed? I'm in the same boat...

I had no problem with the dealer on this problem. They took it for a drive and after checking the tsb they replaced it no questions asked. Sorry your having problems with them. Good luck.

grantoser: your dealer is giving you BS. Reading from the Ford notice I received JUN 2011, it says: "Ford Motor Company is providing a no-charge customer satisfaction program (program number 11B25) for your vehicle, with VIN shown above.." And, the notice had my VIN. It goes on to say Ford has authorized your dealer to inspect the driveshaft and if necessary, replace it free of charge (parts and labor) under the terms of this program.

Technically it may not have been called a "recall", but it clearly provides the dealer the OK to replace the driveshaft it it is exhibiting the clunk. My recommendation is elevate it someone at that dealership that has common sense and customer service skills. If that can't be found, find another dealer. Might help to contact the original owner (if possible) to see if he received that notice from Ford.
