Dodge as been having some of the same issues. Try going to some of the other truck forums and reaading a bit. I think pretty much every manufacturer has had an issue at some point.

 

This is a weird one I have read about for sometime. I too own a 2013 157" wheel base crew cab..... and I have no vibration. Loaded to the point of being overloaded to empty the truck just rides like any other truck I have owned. It's funny as my mother has a 157" screw in the 2014 variety and it too does not vibrate.


Shudder on the other hand on take off is a totally different ballgame. Mine axle wraps so damn bad I broke my drivers side axle shaft in the rear end. I bought Cal-Tracs to fix my issues and just haven't installed them as I taking this truck for it's last kick at the can for warranty on the a/c...... another known problem Ford hasn't dealt with. After that it's time for my heads, cams, headers, rear diff rebuild and cal tracs to go on so Ford will be off the radar for me. That said a person shouldn't have to live with any vibration. I know indexing a 2 piece is important as is pinion and carrier bearing angle. You would have to go beyond any Ford dealer to find some resolution on whether or not anything there could be done as Ford won't have the tools or knowledge in their service departments to figure out if that's an issue or not. I mean yeah they could..... but they aren't a driveline shop setup to check balance.


One thing I think compounding a lot of the shudder is shock placement...... it wouldn't hurt to have the shocks offset like every other truck I have had. My 05 Sierra is crew cab 6.5' box truck with a 2 piece shaft and it will axle wrap a bit if I make it do it but not like this Ford. It also has way heavier leaf springs and offset shocks which help dramatically. The leaf springs in these F150's are very flimsy.....I also own a 2013 supercab ( both my trucks are 7700 GVW 6.2 powered trucks) and it axle wraps pretty bad too..... just less noticeable as it has over 1000 lbs loaded in the bed at all times.

 

I have the same problem with my 2014 Screw 6.5 4x4 Eco. Been fighting Ford for two months now and had them finally tell me this past Tuesday that its an acceptable characteristic of the vehicle. I am so disappointed, I had this same issue with my 02 F350 and I was just about ready to go back to a Ram as my previous ones did not have this problem. Test drove the Ecoboost and it changed my mind. If I only knew then what I know now I would have never made the purchase. It blows mind mind that Ford has been making trucks with drivetrain issues for 15yrs now and refuses to do anything about it.

 

Is this issue just for the eco or is the 5.0 have the same problems?

 

The issue seems to be with 2009 to 2015 F150 usually long wheel base crew cab 6.5 ' bed. The suspension is to light and poorly engineered. After months of getting no where with Ford (new drive shafts, upgraded trans mount, changing tires and wheels and changing pinion angle at both rear end and carrier bearing) I ended up resolving the issue with air bags. Run 5 lbs with no tow and dial the pressure in for your particular towing need. Ford could not make up there mind if it was a 'known issue' or there was 'no issue'. Either way they would not or could not fix it. I have bought dozens of Ford Truck but since they would not make good on this one it will be my last.

 

Man thats really horrible on ford. Sounds like their egos are getting in the way of their customer service.

 

I have air bags and it did NOTHING for my shudder upon take off. Very annoying but I live with it. Disappointing. I got the same answer from my dealer as many of you had. "We can't do anything about it." My service rep said he was told that by a Ford engineer.

 

Makes me skeptical about dropping 50 grand on a truck that is going to have problems from the get go.

 

So this is an old thread. I have a 2013, Lariat with the same issue concerning the shudder. I presume no actual fix was ever found. I bought this truck to tow a camper with and unfortunately when I tow, the entire truck vibrates and like the rest of you, I don't particularly care for it. I'm looking at possibly trading it in unless some has better ideas to help point me in a better direction.

 

you can have someone check the midship bearing. they go bad, but it still may not completely cure the problem. My Bridgestone (vibrate for a while, after setting all night,also check the aluminum rims for bends.

 

I just have that shudder at low speed. Its annoying.

 

 

I'll have to check that option out.

EDIT:
That solved the "slipping" or "shudder" feeling?
