Picked up my truck yesterday and guess what...

NO VIBRATIONS!!!!!!!!!!!!!!

I've put 55 miles on it so far and no vib. They replaced the driveshaft and the body mounts. Lets just hope this is a FIX and not a band-aid

 

DS, untill this post of yours I had no idea the dealer threw in the towel on your truck. If they won't do any more then you have no other choice.

 

My 2004 Ford F-150 has a serious vibration problem.. I have the smoking gun stating that there is no fix. I won my lemon law case and Ford reaccuired vehicles stuck me with a $7,000 mileage fee.

 

I can help It seems that this is their plan for ignoring a severe problem. I won my lemon law case and seems like we both travelled the same course of action

 

...Welcome OKCLEMON, to Ford Truck Enthusiasts!
Stick around someone will be by shortly to answer your question.
We are happy you have chosen the best source for Fords!

…..See you on the boards.

 

Dont let them get away with this..... There is an engineering problem and ford knows it. I can help in going for a lemon law win. Also ask for a replacement vehicle in a lemon law case. watch Ford do a dance trying to prevent a win.

 

I have been following these threads about vibration with a lot of interest.
FWIW, I have a theory: SYMPATHETIC VIBRATION of the frame.
What is the most unique feature of the 2004 - 2006 F-150's? It's ... the super-rigid box frame! Looking at mine, I see an incredibly massive box frame that goes back as far as the front mount of the rear leaf spring. From there back, the frame is much thinner by comparison. Most of the strength is under the cab, not under the bed! WT...?
My theory is that the frame is oscillating like a banjo string with all of the bending taking place right where the frame pinches down at the forward leaf spring mount for the rear axle. Depending on the length of the frame, there would be a certain frequency that it would vibratate. The source of the vibration could be almost anything:
Flat-spotted tires.
Tires out of round.
Wheels out of round.
Tires out of balance.
Driveshaft out-of-balance.
Brake rotors warped.
Engine vibration.
Washboard road.
Pot-holed road.
You name it. If there is a small source of vibration at a frequency that the frame likes, the frame will magnify it. That's the definition of "sympathetic vibration".
My truck is a 2006 F-150, 145" wheelbase, Regular cab with 8' bed. I have no vibrations, except when I hit a speed bump or a pothole. The vibration instantly damps-off the way it should. That is what I would consider "normal". I really feel for the guys that have the major vibration problems. If my theory is right, then it's characteristic of certain cab/bed length combinations. I do sincerely hope that Ford comes up with a real fix, but I suspect that the frame itself is the problem.

 

That's an interesting hypothesis, Enthused.

We could test it by doing a poll of people who have had the vibration problem.

There is indeed the possibility of the different wheelbases of the truck (and therefore frame lengths) having different harmonic resonances of vibrations in the frame.

So we have:
Regular cabs: 125 and 145 " wheelbases
SuperCabs: 133, 145 and 163" wheelbases
SuperCrew: 138.5 " wheelbases
new 6.5' Supercrews: 150" wheelbases

Could we set up a poll also containing the 4x2 and the 4x4 options for each category? It would be quite interesting.

 

Regular cab; 8' bed, 145" wheelbase, 4x4, no vibration issues.

 

04 Lariat Supercrew 4X4, major vibrations, lemon law traded for:
05 King-Ranch Supercrew 4X4...started having vibrations after 5K miles. Traded it for something other than a ford.

 

Great poll idea,my truck(formally know as the "vibrator") 2005 f150 supercab flareside 145 wheelbase 4x4 5.4 with 3:73 limited slip

 

I'm looking aruond for a poll tool on this forum, but I can't find one. I thought most internet forums had button to set up a poll with.

It's ok. We'll do it the hard way then.

 

I am sure they knew you were coming. I recently won my DSB case and you need to start writing a complaint letter to Ford. (certified). I have valuable info on the DSB/Lemon law process. I have a horror story that is bad for you and a money maker for Ford. I wholeheartedly agree that a class action law suit is needed to stop the greed.

 

I have a 05 screw 4X4. I noticed when I pulled a buddy's trailer that the truck vibrated badly at the rear end. The box shook bad!. When I'm not pulling anything I've noticed a slight vibration at certain speeds. Have'nt taken it back yet. I've parked it for the winter.

 

If someone starts a class action against Ford sign me up. I think this is the best way to get Ford to do a recall. Instead of going for the lemon law as individuals.
