Ford F-150 (2004-2008) :: Vibration Starts Above 45 MPH - Truck Shake Only When Pulling A Trailer?
Dec 11, 2005
I took it to the dealer and they blamed the trailer. I told them that I have pulled two different trailers and it did it with both. Then he said that the trailer was not heavy enough to weigh down the springs. So now I not suppose to tow an empty trailer? Also my father in law has pulled the trailer with his Z71 with no shake and the other belongs to a neighbor with a 98 F150 with no shake. The vibration only starts above 45mph. Any clue as to what could be causing this?

Over the past year, I have had an issue with the front end shaking on my F150.
I have a 5 x 10 trailer. Weight capacity is roughly 2200 pounds. I hook up my trailer empty and head down the road. When I hit about 55 mph and above, the front end starts bouncing/shaking/vibrating.
Now I put a load on the trailer. Get going down the road. Hit those same speeds - no shaking/bouncing/vibrating. I have had a mechanic ride with me to check it out. First place to start, he told me, jack it up and see if anything is loose. I have not done that yet.
He has the same opinion as I do. This makes no sense. No load, shakes. Load, no shakes. You would think it would be opposite.

I have a 07 with the 5.4 engine and it has started to jerk or miss sometimes when I'm pulling my trailer. I'm thinking about changing the plugs, but the dealership is telling me they will break off in the head.

I recently purchased a 2006, 4x4, low mileage and when towing a trailer the truck develops vibration right at 52 mph. Dealer has not found the problem.

My truck makes a horrific screeching sound when it's loaded or pulling a small trailer (2000lbs) up hill. I discovered last night while I had it in drive, if I hold the brake and give it a little gas (like if you were trying to do a burnout) it will make the screeching noise as well. It won't break the rear wheels loose either, which makes me think it's down on power or the transmission is slipping.
My first thought is the transmission, but some searches on this forum describe U-joints or the carrier bearing as possibilities. The previous owner told me he replaced a U-joint just before I bought it, so I'm not ruling that out at all....
My truck specs: 1995 351 E40D 4x4 (manual transfer case & hubs), extended cab eddie bauer. 158k.

I have an 07 F150 xl 2wd 5speed. It has a vibration/shake at about 30-45 mph no matter if its in gear or neutral, or if its under throttle or not. It also gets a little worse when breaking coming down from about 45-30mph.
I was thinking at first it was the wheels out of balance since it was only at a certain mph range but the braking thing has me thinking rotors. The truck has about 51000 miles on it.

After returning from about a 5 hr roadtrip, I backed my snowmobile trailer up my steep driveway in 4wd and the truck did not want to move after that. The truck is an '05 SCREW 4X4 5.4L with about 110,000 miles on it. Trailer is probably around 1,000 lbs with the snowmobile on it.
The driveway is steep and short. That combined with the 90 degree turn to get in and some uneven terrain and part the path onto slippery frozen grass makes for a bit of a rodeo trip backwards up the driveway with a trailer.
Anyway, after getting the trailer up into it's place, I unhooked it, switched back to 2wd, disengaged the parking brake, and put it into drive. The truck didn't roll which was weird as it's now in drive pointed down hill. With about 1/4 - 1/3 throttle, it crept forward. Again, this is down hill. I got out walked around the truck (make sure I didn't forget to unhook anything etc) and tried again. Same thing.
Once I made it to the fairly level street, the truck would still only move, barely, with about 1/4 - 1/3 throttle. Now it was like some of the wheels were free but at least one had to break traction with the pavement to allow the truck to move forward. So with constant pressure on the accelerator it would chirp one or more of the wheels a bit at a time as it crept forward. Acted like it was in some sort of imaginary tug of war. After about 40' of driving it worked itself out. I've driven about 10 miles since and seems just fine.
I'm concerned because I plan to do this frequently with this trailer and in the summer frequently with a boat weighing about 3,500 lbs although shouldn't need 4wd in the summer.

My truck trailer connection has no power to the + pin, called the Trailer Tow Battery Charge. I traced back to the fuses and relays and discovered the relay missing. Unbelievably Ford is having a hard time with this relay. They don't seem to be sure which one it is. My owner's manual says it is a Full ISO relay. But Ford doesn't like that description.
What can I use there? Is there any after market relay available that would fit. Napa said they don't have anything listed, and O'Reilly and Autozone look at me with a stupid expression. I also need one for the starter relay. Mine was replaced with a anti theft device that has a remote control. I want that removed so I need the realy.
All the relays appear to be the same. I plugged in the blower motor relay in the trailer tow charge position and got power to the + pin. But I need the blower motor. The Ford guy said that it might be the right one, but he couldn't be certain and if I plug it in and it doesn't work it's my loss.
This is for the 2006 F-150, 4.6l truck.

.Here is a run down of my truck 05 5.4L Screw has 130K on it. Sometime when going up a slight incline the truck at partial throttle will shake very very little. if I put my foot into it the shake goes away and the truck response just fine. It only does this when going uphill on the freeway and on the streets here in Dallas that have slight inclines.
The truck is not throwing any codes nor does it stall at lights. Starts right up in the morning and runs good. Nothing done to the truck except I have an Edge programmer and Magnaflow exhaust. I have pulled the programmer off and returned the truck to stock and it still does the same thing.
I bought the truck used in 07 had 40K miles on it. I'm thinking spark plugs or maybe a coil is going bad. But this doesn't happen all the time just here and there.

Shortly after having my tires rotation/oil change service, I noticed a strong vibration around 45 mph, enough to visibly shake the passenger seat. Other indications:
- It is most noticable when accelerating (e.g. entrance ramp), much less when coasting at 45. I can coast at 45 and when I accelerate feel the vibration increase.
- I did not notice the vibration prior to the tire rotation, so I think it is unrelated to my accident in November.
- The vibration is not apparent at all below 40.
- I had all 4 tires rebalanced (thinking one of them may have thrown a weight) and I still have the vibration.
- I do have a little irregular wear on the tires (inside shoulder).
Before I take it in and have it looked at, I was thinking of taking off one wheel at a time and testing the car w/ the spare on to see if it is one of the tires.
Any other ideas about potential problems that could cause this vibration?

When I put truck in 4wd rear end starts locking up. Take out of 4wd its fine. Just put 2 quarts of fluid. They didn't have the 75-140 so I put in 85-140 was that bad. Had rear rebuilt a year ago. Mechanic said he had to put a different gear assembly because ford didn't make the original any more. Ever since this was done rear just never seemed right. Now in 4wd if I go straight it's fine but as soon as I make a turn rear locks up almost coming to a grinding stop.

Read a few references but nothing seems the same as what I have... 2001 Ford F150 Larite 5.4L 4 x 4
When slowing down, at speeds of 3 to 4 miles per hours truck starts to shutter. It is not an engine issue, nor a brake as it will occur with brakes on or not applied. Engine is running smooth, seems more mechanical that fuel or brake related. Shutter is not slight either.
Both CV axles, hubs, rotors and upper and lower A Frames have been replaced. Shutter was happening prior to the replacement, they were replaced as preventive maintenance. Shutter is profound enough to shake the mirrors. What it can be.

I just bought a 2006 F150 with the 5.4 triton motor. Under acceleration at around 40-45, the vehicle starts to skip and shudder.
Based on what I read online and the fact that I pulled a code for a #1 cyl misfire, I assumed that i just need to change the plugs, and I am trying to scheduule that now.
I just read another post about the TC not locking up due to needing the filter and fluid changed and a way to fix that would be to take OD off and see if it still does it.
When I drive with the od off, it does not do it but i am now confused since i got the one code for a misfire.

I'm having an issue with my 2005 f150 xlt. Its been happening for almost near a month and still cant locate the issue .
It has a vibration at 75km throughout the whole truck. Ive tried multiple things done to it by a mechanic, such as having the tires balanced and the ujoints replaced. The problem still persisted and after attempting to test out to see if press/releasing the parking break (my mechani suggested trying that out), my driveshaft fell off.
Apparently the center bearing snapped and cant simply be replaced on the 05's. So i had to get a new driveshaft installed (used, both the 3 mechanics I've gone to say its in good condition).
Even after replacing the driveshaft the issue persists - however it seems a bit softer than it was (I am guessing the old driveshaft was worn from the vibration causing it to be worse). After that I took it to another shop to see if they could locate the issue. They did a driveline inspection and engine inspection too see if a misfire could be the cause.
Again, nothing was found. The only thing they were able to find was that the issue only happens under load and slightly occurs at 40 and 100km as well (although alot softer then the one at 75) and they say they cant find anything physically and it was a mystery to them.

I have a new to me 2005 F150 with 86,000 miles. When I am driving through town at a low acceleration or a constant speed at between 40 - 50 mph the truck starts to sputter and kick a bit. When I give it some gas the problem goes away. This gets worse when I pull my bass boat, and starts at around 30 mph. When I hook it up to a reader I get a P0316 code. Only code I get.
Also when I am driving through my neighborhood between 20 - 30 mph I get a noise that sounds like there is a plastic bag stuck under the truck. I have checked under the truck to see if the firewall is loose anywhere, but could not find anything. Other than those two issues the truck runs great. What these problems could be?

This is concerning my little brothers truck. It is a 2008 4.2 liter with around 55,000 miles on it.
He drove it to work today, and called me this afternoon saying that the truck starts then dies a few seconds later, and the battery light illuminates. He and a coworker checked the battery and connections....cleaned off corrosion on terminals, battery reads 12.xx volts without a load on it, it is the original though.
As of right now he is changing the fuel filter which hasn't been done yet. I also know of issues with the fuel pump driver module. I remember checking the one on my 2005 back when I owned it. As I recall it causes a no start condition, but would it cause a start then stop condition like this? He will check this when he is done with the filter.
Anything else that we can check in a parking lot to try and at least get it home?

I recently purchased a used 2006 Ford F-150 (5.4l RWD). I was fully aware of a problem with the brake rotors when I bought the truck from a dealership. They supposedly changed the rotors and the rotors appear to be new...But every time I brake the truck almost flutters in the front end. I haven't noticed vibration while on the highway, only when braking. I am worried because I can fix it I just cant seem to figure out what the problem is.

My 08, when I connect my 7-pin trailer up, bouncing down the road that message and tone CONSTANTLY going off....drives me nuts! I have went thru the wire harness 2x now, cleaned all the contacts, etc. Any other thing short of a 12 gauge? When it does pop on, the controller starts flashing...I've reached down a few times and manually hit the brakes and it still hits em so whatever it is, I feel its very minor or whatever....just don't know where to go now! All contacts have been cleaned good as well.

My F-150 has developed a rattle and vibration at idle that only occurs with the truck in gear and stopped (with the brake depressed.) The noise appears to be coming from the front of the truck, perhaps from the driver's side (though it's difficult to tell while sitting in the cab).
Before I go crawling around underneath with my son holding the brake while the truck is in drive--I would sure like to know where it might be best to point the flashlight.

I have a 2012 Ford 4x4 crew cab 150 xlt. 15,000 miles. When pulling my dump trailer I was stopping to turn and the transmission disengaged. Once I turned the corner coasting the transmission kicked back in again. During this happening pushing the gas did nothing but rev up engine. My dealer said if this happened that a warning light would of came on or a wrench would appear on dash but it didn't. He said then it didn't happen. This happened 3 times in 10 miles of driving. I had it in tow mode.
