I have a 2010 King Ranch 4x4 with less than 3K on it and I'm having the same issue. I will be taking it in to the dealer soon. More to follow on what they have to say. Also, having issues with the 6 spd tranny. Seems to be confused when to shift and when engine is cold, it shifts into 3rd gear very hard. I'm was told to drive it for another 2-3k and the tranny is apparently supposed to adjust itself to my driving habits. I'm not buying it....I have three different driving habits...in town, highway and pulling a trailer. I'm also getting a slight griding noise for just a few seconds between 25-30 mph. The dealer sent sound recordings and diagnostics to Ford HQs and I was told that there was no fix for this and it would not have any adverse affect on durability, life or performance of trany. My past trucks have been an 03 FX4, 06 Lariat 4x4, 08 FX4, all S-Crews and all have had minor issues, but known like this. After reading some other posts, it appears that many others are having these issues. Just wondering why Ford hasn't done more to correct the problems. I'm a die hard Ford guy, but these Trucks cost to much to be having all these problems right off the assembly line! Thanks for listening and letting me vent!
2. There is a TSB out for BOTH your issues
3. Many people have done the fix and have no more issues.
4. Read the TSB and make sure they do it accordingly
5. ALL cars especialy first run new cars/trucks have issues.
6. 20 people on a forum out of 50k trucks does not mean its wide spread.
7. If you get crap from your Dealer then take it to another one.
8. If you dont get satisfaction call ford.
9. If that dont work well I am out of options
seriously, I have had the issues you described my dealer took the truck and fixed it been running good for 5k no more issues and I am OCD but I understand things make noise. Oh and your tranny is supose to learn your driving but it should still shift properly that is Bull ****.

I had originally posted that I have had my 2010 Ford F150 in 3 times already to lube the yoke to take away the clunk. I am at 5300 miles and it is doing it again. I am thinking the mentioning of another dealer may be the answer. I can tell you that I am the guy who will not accept it. The dealer told me and noted on my work order that this was a "characteristic " of the truck. I say nonsense as it didn't do it when I took it for a test drive nor did it for the first 1500 miles. I have talked to Ford several times and will talk to them again. I won't let Ford get away with telling me it is a characteristic. I wrote a letter to the dealer on Friday letting them know I had no plans on bringing it in to have it lubed for the extent of my 75000 mile warranty. It seems like the constant fixing and removing of parts is more costly than replacing the entire driveline. This is not a common problem so don't let them tell you all Fords are doing it. I have called around and this isn't characteristic. You are right, I didn't pay $40,000 to get a truck that clunks. I will keep you updated and would appreciate it if you would to.

My 09 screw has the same problem. I brought it to the dealer and they lubed up the slip yoke. The problem disappeared. About 2k later its back. The dealer told me that ford is aware of the problem but has yet to come up with a permanent fix.I did notice that if you put it in 4 wheel drive the clunk goes away. I told the dealer this and they said its because the drive line was now loaded. They also said if I put a 4 wheeler in the back that this also loads up the drive line and the problem will disappear. I suggested that ford should just put a grease fitting on the drive line so you don't have to take everything apart to lube it up. If ford doesn't come up with a permanent fix I might just put a grease fitting on myself. Any others have an opinion on this?

Grease fitting only aids in applying more grease and doesn't address the root problem. Also, there may be metal shavings generated that need to be removed. Splines on mine were damaged beyond regreasing - to what extent I don't know. To me, wearing this prematurely suggests a basic design flaw or use of inferior materials.
Adding weight in the bed probably changes the driveshaft angle enough allowing a bit further engagement of the splines (better in general) and probably such that the "bad" areas are not mated directly in the same spot - Just my theory.

How's your truck running? I'm taking mine back tomorrow for the second time. First time they greased the yoke and said that should take care of the problem. It didnt! Curious what year/model is your truck. I have a 2010 4X4 F-150 with a single drive shaft. Can you tell me exactly what the mechanic put on your work order? Thanks for your feedback.

Just picked up my truck from the dealership for what I believe is the same issue you all are having. Mine doesn't do it very often and I can't duplicate it when I want. The techs at the dealership kept it all day and were unable to duplicate either.
Here is what they put on the invoice:
Unable to duplicate customer concern. Check for codes, none. Check OASIS, none. Contacted hot-line. Stated reset KAM in transmission control module as per hot-line. Advised customer some harsh shifting somewhat normal for 6R80 transmission as per hot-line.
The problem is that I am certain it is not the transmission. I have already had TSB 09-11-5 and 10-12-4 done back on October 29th. The shifting is fine. The clunk only occurs when letting off the gas at just the right time or getting back on the gas after coasting.
It doesn't really bother me that much. As long as it isn't going to lead to a larger issue later on (warranty is up in 5,000 miles) then I won't concern myself with trying to correct it.

My 99 Ford Ranger has a noisy slip yoke and has for 120,000 miles. When it starts to bug me I pull the shaft and lube the yoke. Most of the time I just let it go. I never attempted to find a permanent fix because it didn't really bother me that much. When I took it to the dealer, many miles ago, all they did was lube the yoke and charge me.

See mine is the same way. It does the "bump" confused shift thing at a low speed stop or start, but i can in no way force it to duplicate the problem so i have yet to take it in. I know my dealer and service department are top notch, but unless i can figure out a way to duplicate the dang thing i'm gonna wind up with the same results that you got, and have no truck for the day and no solution.
