There are some good ideas here, moreworktodo, from your fellow forum members. Thanks to all! It is also a good idea to bring your truck in to the dealer for a diagnosis and some suggested next steps. I can escalate this to the regional customer service manager for further assistance. Please send me a private message with your full name, current mileage, servicing dealership, VIN, and best daytime contact number, so I can get started right away.

I had the dealer do mine. Hasn't come back yet (30,000 more miles). Might be your problem.

Just had my TSB re-flashed and it did nothing. When I dropped it off, I even mentioned maybe the yoke needed to be greased, which IMO is not a fix since it did nothing when performed on previous 09 FX4. Was told will check it out. Service department could not replicate which always seem to be their go to answer or more likely, Ford's standard excuse. So, in the end they just re-flashed it.


By the way Ford moderator, I called you guys a while back regarding a different problem I was having and was simply told to take my truck to a different dealership. Like most hard working people who are buying these trucks, we have better things to do then go around to different dealerships. Very disappointing to say the least.

i would have to drive it to see exactly what it is. My suggestion is bring it in, and you drive with the tech to see what he says.

I'm glad to hear that the dealership was able to resolve the concern, murf. If you have any feedback you'd like documented, send (PM) your full name, servicing dealership, and best daytime contact number my way. I'll absolutely get this recorded.

What's the model year and mileage on your truck, Chaseit23? Please send this information privately, as well as your full name, VIN, and phone number; it sounds like you've given our Customer Relationship Center a call. I'll check our records and investigate this further.

I know it has been a while but wanted to close this topic. I now know what "slip bump" is. And, I can confirm that is what I feel. Many of you were correct. It is definitely the splined slip joint between the two lengths of driveshaft that I feel. Might have to explore a lubing the driveshaft. At first I thought "what a joke, driveshaft lube?" But, I know see the light.

And, for documentation it seems to get better in cold weather. It was very noticeable in ~70F weather. Now that it is close to 0F it is gone, even when I try to aggravate it.

Thank you all for your insight. It is great to have the ability to "check the pulse" of other F150 owners and get feedback. Thanks!
