I may be headed down the same path as some of you (it seems that way). Ford road force balanced my Tires and said that 3 of the 4 Toyo MT tires were out of spec or over the 40 lb limit for an e rated tire. This would be 2nd and a half set that would give the same ride yet balanced on a regular (non road force) machine. Toyo customer service is taking back the tires and my tire store is putting on cooper at3s. I'm not happy about this at all and have had a fantastic ride from the Toyos in the past, including the set that was on the truck previously.

Btw, is Crystal still around? If the next set of tires does not fix the problem, I don't know what to do.

I have been wrestling with this one also without a solution. However, I have been having trouble recently with the front brakes on my 2011 250 FX4. I had a seizure on the LF caliper so the local mechanic replaced both front calipers. I noticed a a significant (qualitative) difference in the hop afterwards, it was of lower amplitude and arrived at a slightly higher speed.

This is making me wonder if the front disks are contributing. I'm wondering if their natural warpage, small though it may be, is moving the caliper back and forth just enough that when it hits its first resonance frequency it contributes to the hop. I don't think the calipers move freely enough on the sliders. Has anyone tried anti-seize on the sliders and noted a difference?

Well my truck is back with Ford as I have replaced the Toyo MTs with Cooper At3s. The vibration has lessened but is still there. They are trying to road force index ( I believe that's what they are calling it ). To those of you who had the dealer swap in a set of tires off the lot, did you have to suggest them try that? I do find it funny, that they are determined that the problem lies in the 14 different tires that have been on the truck, and not something else on the truck itself. To my non expert self, it seems as though the tires are amplifying the problem that lies in the truck. I've gone down from a 80 lb mud tire to a 60 something pound AT.

Anyone ever try these?

Sulastic. Leaf Spring Shackle

Rbalan1,

Man, I feel for you... Like you, I have spent a great deal of time and put forth an ungodly amount of effort to find and fix this problem but had no such luck. Well, I take that back. I did get rid of my problem but the expensive way (bought a new truck). Even though I love love love my new truck it still blows my mind that so many of these trucks have this problem and Ford doesn't know why or how to fix it. Fingers crossed the new frame design in 2017 will "fix" the dreaded super duty hop.

I do like the idea of trying the Sulastic Shackles posted by chipster314. Curious for someone to try them and post results.

It's not the wheels or tires. Went to dealer today and put on brand new wheels and tires from a 17,same crap . They had a new 16 still and I took it for a ride and it road like crap as well. Ford are *******s if you ask me, and I work at Ford.

Has anytime tried new shocks?

 

[Rbalan1]

There's a much longer thread on another message board (can't remember which one) that members kept throwing money in their trucks: replacing tires/wheels, alignments, shocks, steering stabilizers, ford's dampener, traction bars, etc. pretty much same results every time....a lighter wallet and time they could not get back. One poster fabbed up some bracing on his frame and said it had pretty good results and there is a video of the frame vibrating to show its the culprit. Bottom line is to fix the problem = sell the truck or just live with it.

 

[chipster314]

Can't live with it and I shouldn't have to eat the cost to get rid of it. Sucks big time

 

[Rbalan1]

Sure does, I've almost got mine paid off?. If I can avoid going 47-50 mph, it's manageable around town, which is a bulk of my driving. I try to stay under 65 on the highway, which is a pain for long trips. If you want to minimize vibration, go with the smallest diameter tire with the least amount of weight. 35" Toyo mts were flat out awful, 295 Toyo mts were bad, 295 Cooper at3s are about the best I can deal with. Small gravel gets caught in the tread and thrown out at higher speeds and thankfully it was a dry fall for hunting.

I'm no longer a Ford purist after this, never bought a non Ford in my life, but after my 6.0 and this issue it's time that Ford starts working for me instead of blind loyalty. It's not to say I'll never buy another Ford or that other brands don't have their issues, but next vehicle just about all brands will be on the table.

Btw, this is why the 2017 super duty frame is changed. It unfortunately took over 15 years for them to figure this out?.

My 2004 6.0 was great. Loved driving it down the hwy empty. I'd take it back in a heart beat.

Just got a 2013 F250 4x4, noticed a vibration, like a tire was out of balance. It occurred around 46-50 mph, then smoothes out, starts again at 68-80 mph. The dealership has replaced all wheels and tires twice......still not fixed.

Any solution?

I also have a 2013 250 king ranch and it has a rear vibration, I have had it at Ford, local axle shop I have had new drive shaft installed. I was told it could be a bad tire had them replaced with 4 different brands and vibration is still there. I even put aftermarket wheels on and still have the same vibration.

Try this get 4-5 100# sandbags. Cover back seat with cover, put bags on back seat. Do test drive, see what happens.

Once I had passengers in back and noticed no vibration in 45 mph nominal range.

And report result!

After fighting this for 3 years, I know Fords response is "this is normal characteristic” of the super duty. So I guess your two buddies better go see their dealership and get their normal rear end bounce installed.... :jester:
Seriously though, I hope the road force balance helps you but I know it wont.

Ford has never been able to tell me why only some trucks do it if it "normal".

Load 4-5 sand bags on back seat. Do test drive, see what happens.
I once had passengers in back seat, mysteriously, no vibes at 45 nominal mph.

And report results.
