Ford F-150 (2004-2008) :: V8 Has Intermittent Freeway Vibration?
Sep 14, 2014
I have a 2004 Ford F-150 4x4 5.4 V8 SuperCab. Back in February I lifted my truck with 2.5in coil spacer adapters, out back add a leafs 2-3in. Now I can't say for sure it stated then, but for a while now I have an intermittent freeway vibration. Typically around 70-75mph it is at it peak when it does it. Other times it can be very smooth. The vibration is like an oscillation that you can feel in the body. Not much felt in the steering wheel. The vibration can start and stop any time and last for any amount of time, there is no common point for when it starts and stops. Right or left turns does not cause it to start or stop, sometimes it feels like big bumps will start or stop it but not all the time.
I have a rearview aftermarket camera, I took it off and mounted it several locations to view tires. The fronts are steady while at freeway speed and with the vibration.
After tie rods were changed and no play in any suspension/steering parts, the truck has been aligned several times. Tires are new and have been balanced twice. The driveshaft is new (new U-Joints, shaft and slip yoke) and is balanced, which it did improve the vibration but not perfect. The rear brakes have been inspected, no sign of overheating on the drum or the shoes. The lever is all the way back. So I don't believe it is it, although I did not fully disconnect the cabling. If it was the brakes why would it be intermittent? I had a shop replace all bearings in the rear axle, due to the pinon bearing noise. I saw the TSB's already on vibrations and none conform to my situation. The hubs have been checked, with the engine on they are unlocked.
So as I stated I can't say for sure it started after the lift but maybe due to the lift the differential pinion angle to driveshaft and to the transfer case is too high. Maybe I need some pinion shims. But I haven't heard of anything else needed to do this after a 2-3in lift. I'm getting tired of chasing this vibration.

I have a 2004 chevy malibu LT V6. Got it in 2009 from a dealership near where I live. During the road test I did not notice the vibration, may be because I did not drive it on a freeway. Point to be noted that it came with 2 brand new front tires. I called the dealership and they did balanced the wheels for free of charge. But the problem did not go away. This time I took my car to pepboys for wheel balancing. It is better now but I still feel the vibration on the wheel @ the speed of 60 or over. I have done wheel balancing and replaced back tires. Problem still remains. I own some other cars and they don't have this issue.

This has happened maybe 3 times in the last month. Once merging on to the freeway. Another while cruising 70 in the carpool lane. And the last one I was leaving the job site and it did it.
What I'm talking about is a quick like cut out or stall. Maybe a second of time then back to normal. It also makes a clunk sound. You know these things are hard to describe.
Just don't want to freeze up on the freeway and cause a wreak. Also can I tell from my vin.# if I have limited slip or posi.

It started completely unexpectedly about a month ago when I was driving around 70kmh while cruising. I would get a few "jerks" of a sputter, then was able to drive a km or 2 before it did it again. I drove to a friends and he got in, and the sputtering episode was over.
Since then, I cannot simulate the way I was driving to make it sputter for any mechanic, but I have been getting sputter on and off the last month.
The one time I got in the truck and started it, put the truck in drive, and it sputtered for a few seconds. I wasnt driving at all this time. This was the only time It sputtered in a stading position.
Here are a few points to maybe, narrow down what happens.
-I am usually driving around 70-90kmh
-I am usually under no loads (not towing, hauling etc).
-My mileage seems to be getting worse.
-this was normally happening not only when the engine was warm, but when it was warm outside and I was driving it for a longer period.
-When I started driving my truck I calculated around 16mpg city. I am currently getting around 13-14. I was on the hiway for around 250 km and got 14mpg. Seems I get better mileage when puttering through the city than when I am on the highway.
I had the truck in to a dealer 2 weeks ago. They did an injector flush, new sparkies, number 5 coil, and took me for $780, saying the problem is fixed.
A few days ago, I was driving on the onramp to the highway accelerating around 90kmh and for around 4-5 seconds I was sputtering and jerking so bad I thought I was done for. The truck finally recovered and again, haven't had any episodes since.
The dealership says their electrician doesn't know what to do, and would need my truck for 4-5 days to try to see the problem for himself. I can only think, as a non-mechanic, that it is something to do with some sensor, possibly a fuel, and/or oxygen sensor.

Intermittent starting issue in these things? Seems to be getting more common for me this winter. Turn the key, it turns over, and then I let go of the key and she doesn't light. Then when I try again, it's like the engine is flooded. I have to give it gas to start, which I know is a no-no in fuel injected vehicles. Other than that, it's fine. No sputters, no hiccups, runs strong, good mpg, etc. But I'm getting annoyed....

For the last little while I have been having an issue with the 4wd in my 2006 F-150 with about 93k on the clock. Sometimes it would engage when I switched to 4H/4L and other times it wouldn't. A friend of mine works at a Ford dealership and said it could be the vacuum solenoid on the firewall going bad. So I bought a new one and as I removed the old one, noticed debris in one of the inlets. So I cleaned that out and neither old or new solved the problem. Then I went through ALL of the vacuum lines and found some debris in parts of them....
Cleaned them all out and still nothing. Then I got to thinking it may be the ESOF motor on the transfer case. Checked to make sure there was power to the plug, which there was. Removed the motor and turned switch, and the motor seemed to be working. Reattached the motor and the 4wd would engage/disengage without problem. Pretty much everywhere I went I would check it and it worked fine . Then all of a sudden it didn't . So I took the motor off, turned selector and it worked fine. No issues yesterday at all.
So, I am not sure if it is the motor going bad or not. Could there be a contact problem? I talked to a mechanic this morning and he told me to drive around with it in 4H for a while because more times than not it doesn't get used enough. I'm just not sure what could be going on...am I missing something?

Over the past few months I've noticed that my truck has a very intermittent shudder under mild acceleration. If I accelerated more during the shudder it seemed to disappear until I let off the peddle a little. When it happens the truck doesn't seem to be lacking power and the engine throws no codes. It happened again today right as I had stopped at a red light. I noticed that it was shuddering at idle too. I shut the truck off at the intersection and the shudder was gone once restarted. What it may be?

I just got the spark plugs changed in my Ford F-150 the other day for a misfire problem. Misfire is gone now. But, as I was testing the truck to see how it performed after the spark plug change, I noticed that as it was raising speed with my foot to the mat, the engine felt as if I was slightly letting off the accelerator and then slowly pushing the pedal back to the floor. It loses power as if you're getting ready to slow down for something and then slowly the power comes back and it does it off and on throughout a WOT run from lets say 40-75 MPH.

I have been trying to chase down a whirling noise that follows vehicle speed since I bought the truck in my sig in Oct. The noise happens whether or not the hubs are free or locked so I don't think it is the front needle bearings. I just changed the transfer case fluid over to Mobile 1 Syn. and there was no change in the noise. I also changed the front pads, rotors, slide pins and calipers a few weeks ago and that didn't have an effect on the noise either. Today I took the truck for a ride and I'm not sure but it seems almost like the noise is a bit louder! And I noticed that if I hit the brakes firmly, harder than a normal stop the noise gets significantly quieter and if I release them again the noise goes right back to normal. This has got me stumped...
Along with this noise, I have a vibration on the freeway that gets worse around 55 and lets off around 61. Its worse at some speeds and better at others. Thinking the two were related I pulled the rear drive shaft and checked the u-joints and the carrier bearing for play. The carrier bearing doesn't have any real play but there is quite a bit of slop, ability to turn back and forth, where the driveshaft comes out of the transfer case. All but one of the u-joint cups were fine. The bad one isn't even too bad just the rubber seal around it is a little off, there is still grease in it and the needle bearings seem fine.

I just purchased my first F150, 4.6L V8, 55,600 Miles. It intermittently has a rough idle and only seems to be when the engine is hot. I've had engine and tranny mechanics look it. The spark plugs have been inspected and are within an acceptable range. The throttle body has been cleaned. There are no trouble codes of any kind. What I can check next?

I have a 05 fx4 5.4L with 85k on it. It has started idling rough when i come to a stop light or slow down to 10 mph or less. It only does it once in a while. There doesn't seem to be any real pattern. The motor shakes until you rev it up and then it goes away.
I have cleaned the maf, put in new air filter and fuel filter. And put in a new battery. Would a coil act like that? Maybe plugs? Or a vacuum leak?

2006 F150 4.2 fuel issue? I get an intermitent no start condition and no obd codes. Then I discover that it really isn't intermittent, it only occurs after I have been running the engine. It will not start for at least 5-10 minutes after I have driven a few miles and shut the engine off. So if I wait 5-10 minutes then she starts and runs just fine. I played with this in the driveway to recreate this condition so I could determine if I had a spark or fuel issue (I have spark during no start). I found that 50% of the time I could start it right back up immediately after I shut the engine off. But if I shut it off right away again, then I got the no start condition again and have to wait another 5-10 minutes.
Now with cold engine I can start the motor over and over. To fix this I read forum after forum, which led me to decide that I had a fuel pump driver problem (module) located on back axle under spare tire. I replaced this and restarted the engine many times. The problem seemed to be gone but this only lasted about 30 minutes. Then it would not start at all and still no codes. I plugged my old module back in and the truck fired right up. So I decided I needed to (flash) pcm for new part but that changes nothing. Still no start with new module and runs with old module. I also replaced relay in fuse panel.

In my 2006 Prius, I just started noticing this recently, but whenever I turn my steering wheel, it makes a weird noise and I can feel something going on through the steering wheel. It doesn't impede my steering, the car steers just fine... It's just an add sound, I don't want to say a cracking sound... but it kind of is? I don't know. I'll have to put a video of it up. & it doesn't matter which way I turn it, it still makes the weird sound and the intermittent vibration... I know it has E-steering and occasionally you can here the motor whirring when you turn it but this is different, it's a loud... popping noise is the word for it! Popping, and I can feel it when it pops through the steering wheel. Again, it doesn't impede the steering ability at all, but something isn't right I'm sure... Or maybe it's normal.

I have a 2006 F150 STX auto trans with the 4.2L V6 that has been having intermittent starting problems. It has 98,000 miles on it. It will start fine 99% of the time but sometimes when I turn the key the starter will grind once or twice then it can go a few weeks with out doing it at all. Then also sometimes it will crank turning over for several seconds but wont start. Then it starts fine the rest of the time. This has happened several times but only happens once every few weeks or so. Just trying to see if it needs a new starter or if its something else. It has a new battery.

Still showing the same codes (per repairman) and still having the intermittent rough idle at low speeds when the engine is warm. It has been so intermittent that I could almost live with it.
So repair guys first replaces the VCT's and runs fine until warmed up and the problem reoccurs with the same codes. He replaces both cam phasers and tensioners today and still same problem and same codes which point to the VCT and cam phasers.
Truck has 80k, city driven, oil changed every 3k or so. Burns ethanol and still runs great at speeds over 10 mph even when this problem appears.

I am working on a customers 08 F-350 5.4l has 135k on it. came in with a severe rattle/knock, running poorly, and dying at stops. ECM gave up 8 codes relating to the timing... Found the phaser replacement steps here on FTE and followed them and replaced the VCT solenoids since i was in there. Customer reported that he replaced the cam sensors already. Ran great for a day, and the next day when I pulled into the shop it gave me a rattle. Not as violent as before but noticeable. I special ordered the wedge and followed the replacement to a 'T'. I have no performance issues and no codes.

I got a 08 F150 with a V6. It's making a very loud and annoying noise that sounds a lot like a bad steering pump, but it's coming from the water pump. I'll be cruising at about 2000 rpm and the noise will start all of a sudden. I step on the clutch and let the rpm drop to idle, and the noise tapers off as the rpm drops and then stops completely. I bring the rpm back up, and there's no noise. There is absolutely no play in the water pump bearing, no leakage from the weep hole, no overheating.

I have had this vibration on the freeway and at different RPMs in different gears and i can figure out the vibrations... its mainly coming from my gas pedal... clutch and brake pedal are usually fine and the steering wheel is alright i guess.
I replaced my dog-bone mount because it was F'd up and got my wheels balanced so those two are eliminated. i know my tires have some camber wear but i feel like it wouldn't be intermittent if that were the case. I am stumped and I hate playing the game where i just replace everything hoping to fix the problem...

I recently had u joints and left front wheel hub assembly replaced at a local mechanic. Ever since I have a vibration between 40-45 and 52-62, the vibration can be felt in the steering wheel, the seat and the floor. The mechanic claims I need a new driveshaft as some of the counter weights were starting to rust. I indexed and removed the drive shaft and had it rebalanced at a local machine shop. This did not solve the vibration problem. There is also a transmission leak starting from the extension housing. How I can start to trouble shoot the problem. 04 F150..
