"Little significance" not having my truck for several weeks at a time, which I drive 25k+ a year? And the hassle of back and forth to the dealership, and having Ford say it's an isolated incident?

Interesting.

Went back to my purchasing dealer, now driving a 2014 FX4. Figured I always buy first model year (6.0 diesel Super Duty anyone?) was time to try the last model year. As much as the wife unit wanted something different, too much of a Ford man.

 

So it says this thread is for 55mph shudder ONLY...is there a thread for a 2010 screw fx that shudders in traffic speaks of 1-3mph?

 

Have you had your local dealer check out your truck, ATX-FX4? They'll best be able to diagnose, especially if you try going on a drive with one of the techs. Feel free to use this to get started, and fill me in with your current mileage as well.

Please keep me in the loop!

Had this happen for the first time today, but I've been expecting it. I bought it used with 44,000 miles on it about a month ago. I already new spark plugs and coils on the way, from what I've read on here they only make it to about 50k.

Have you had your dealer take a look at this, RealQuiet? They'll best be able to diagnose what you're experiencing. Feel free to use this to get started, and please keep me posted!

64K Kms, less than 5000KM on second drive shaft. Original had center bearing failure.

After lifting with 4" blocks in the rear (BDS) it has gotten worse. I've tried changing my center bearing angle using shims. Tried every thing from 1/4" to 1 1/2" and no change. Didn't notice it with 2 1/4 blocks in the rear.
Happens on flat roads between 50 and 60 mph. Random sometimes it does it sometimes it doesn't.

I am going to replace the trans mount with a raptor mount from the 6.2L and see if that helps.

 

3rd time this truck has not let me accelerate and when I push on the gas the entire truck vibrates like crazy. This time I had my wife and daughter in the truck going 75mph on the highway with a huge f350 tow truck on my tail. There was also a blinking transmission or service light. Once the truck stopped coasting, the truck was fine. If I pushed it again later on, it would do the same thing. I took it into the dealer and they had it for 3 days and they couldn't find a thing! $250 in a rental car later...I get my truck back with nothing done and no answers. Wife wants another truck and this time it scared me...what's next?????

 

Is yours and Ecoboost? If so you likely have a intercooler issue. Have you ever had the TSB done for the intercooler issues? It causes misfires as it sucks water through the intake etc.

 

Yes, it is an EcoBoost. I don't think so. They've changed the cat converter and reset everything on the previous trip to the dealer.
