My new 2010 F-150 (now with 1400 miles driven) has had from day 1 a very noticable vibration and audible rumble (especially when the truck is cold) at engine speeds between 1220-1400 rpm. Though evident in all gears, this is most obvious in 1st and 2nd. The dealer's service department recognized the problem, but after their failure to find a cause, they declared it "normal." I asked that Ford's area tech rep take a look at it. He, too, acknowledged that "something is going on" but after failing to figure out just what, he, too, declared it"within acceptable limits." So what now? I have a truck I resent driving. Does this touch a responsive chord?

Well I have searched for clues as to what could be causing the rough idle, from vaccum leaks, to dirty injectors, nothing solved the issue. Short of replacing the entire ignition part by part, I feel as though I am resigned to living with it or sell the car.
 
I know Ford sells hundred's of thousands of vehicles with these engines, maybe we are just the unlucky few, or the only people who notice it and expect more from Ford, hence why Frod does nothing about it.

I have a 2005 Ford Expedition 5.4 3V with the same horrible vibration. I have a normal idle of around 500-600 and the truck vibrates badly at a stop while in drive. It is amazing that no one knows an answer to this problem. I took it into Ford and they wanted over 900.00 for new Motor Mounts....I naturally declined and inspected them when I got home, they looked brand new(no cracks, stretch marks or other odd wear). This truck has 82K on it, it has never towed anything and has had all maintenance done at Ford, including all oil changes with the Ford MC Oil Filter and Ford MC 5W-20 Semi Synthetic Oil. I am also beginning to experience Diesel Sound Tick(included is a weird clanking noise at about 900 RPM [this is only at 850-950 not before or after]). This really blows Ford could give a rats ass about customer care...this is probably the 7th Ford Vehicle I owned Myself and Wife Combined...I wrote a letter and they said Thanks and they cannot help? I wasn't asking for anything free, but if they issue a TSB regarding early make 05 5.4 need the upgraded lash adjusters, then you might think they would do something since the truck falls into that .....I am stuck , but also fed up with the Vibration and don't want to pass this problem onto an innocent person either, I'm just like anyone else, 2 kids with one on the way with zero budget, trying to get around in a truck that's built ford tough, which I cannot afford to fix. Does anyone know the reasoning behind this???? Please message, PM or email y9our issues because I am going to write Ford again including letters from here.

Try the cam-phase adjusters.
There is a TSB on this to replace with new ones TSB 06 19 08".
Search truck sounds like a diesel. Dose the truck sound like diesel after it warms up?

It is beginning to sound a bit like a diesel, but that is not really my concern it is a very strange rattle like sound at 550-650 RPM. Ford said its low oil pressure and the motor needs to be replaced....?? They also said prior that the motor mounts were shot, so don't really know what to say to that.
 
The car has 82K and the plugs have never been changed, but everyone says not necessary.
here are links to 2 videos I have of the car 1 is at normal idle and the other is when you stay at 550 RPM(the rattling/knocking noise)
At Idle
Knocking Noise 550RPM

#150 of 182 Ford F150, 2004 - Vibration Problems (steering wheel, etc.) by bartb65

Stock tires finally wore out but ride had been smooth as silk. Bought 4 new Michelins and sometime afterward, noticed moderate to severe vibration starting about 65mph which mostly (not entirely) goes away at 80mph or so. My mechanic for 20-years has tried everything and is as stymied and frustrated as me. He has rotated, balanced, shaved (rounded), aligned, etc., to no avail. He's also checked everything else he thinks it could be. He and I finally decided to replace these tires with 4 brand new ones (also Michelin). It is less now but the vibration is still there at the same speeds. It comes and goes. It seems worse on curves. I guess I could try a Ford dealer but know that they'll recommend a ton of very expensive things and likely won't fix the problem. Anyone else have or had this problem and fixed it? I am at wits end. Thank you in advance.

Mine has this problem also, It has always had a loud vibration in certain rpm ranges on acceleration That has seemed to get worse Easing up on throttle makes it go away, very annoying, but on this last trip it has developed this bad shaking vibration when a load is put on the motor starting uphill. I was not towing anything but had around 700 pounds of gear in the bed I thought it was rumble strips when it first started happening. scared the crap out of me. My truck is a 2005 supercrew 4x4 with only 37000 miles. The F*^%$#ing truck has been babied. I have never even had it in four wheel drive other than to make sure it worked. How many of us are there with this problem ?

#152 of 182 Vibration at the 1200 - 1800 RMP Range. by noro1

May 11, 2010 (11:32 pm)

I have been reading about people having problems with vibration around the 1200 - 1800 RPM range & the feeling is like driving on the rumble strips on the side of the road. I have this problem too. I have a custom modified 1975 Chrysler / mitubishi LA Lancer that i have rebuild with all ford running gear. 302 Windsor 347 stroker, C4 - C10 stage 2 trans Ford 9" diff with Detroit Trutrac Centre.
At first i thought that maybe the exhaust was touching the undercarriage somewhere. but it's not.
 
The vibration is only there while driving, so i tested it out by putting the trans in neutral when the vibration starts at the 1200 RPM range & the vibration stopped.
Now this is making me think it is the drive shaft that is out of balance.
 
So I am going to get the drive shaft balanced & I will post the results here.
 
I am pretty sure that this is the problem. because if it wasn't a problem with balance, the vibration would be there all the time. the vibration is only there between 1200 - 1800 RPM & then its fine one I get through that rev range. so I tend to go through that rev range as fasts as I can because I cant stand the vibration & the fact that everyone takes notice of my car, it a bit embarrassing. thats my excuse for putting my foot down in second gear anyway : )

hey I have a 99 f150 with a 5.4 . when I bought the truck it had that same knocking noise. and it turned out to be the passenger side exhaust manifold had rotted out. I have herd that ford has a problem with them for quite some time. it sure didnt sound like an exhaust manifold to me but it was. I was just glad it wasnt the engine. hope you figure it out.
unfortunatly, I also have idle problems with my truck and cannot figure it out. I see alot of people have this problem.
