Ford F-150 (2004-2008) :: 5.4 Shudders / Loose Power At About 60 MPH
Apr 12, 2013
I just bought this truck a few weeks ago and rarely hit the freeway. But 2x now when getting on the freeway it will shudder/lose power at about 60MPH. It quickly recovers and then seems perfectly fine. Both times it has happened while going to lunch and when the vehicle is not warmed up. It has not happened on the return trip. I did some searching but nothing seems to be very intermittent like my problem is. Hard acceleration is fine and I have no issues there. Its an 05 Supercrew FX4 with 39K on on it and was babied.

07 f150 4x4 shudders when starting from a stop going around corners. I was thinking of changing the diff. fluid. Is this a good start?

2004 F150 XLT 4X4, 5.4, 142,000 miles... Plugs had been changed at around 75,000 miles... Shell gas used 99% of the time.
Shudders and jerks going up inclines (big or small). Bad gas is being reported at all the local stations...Started using Sea foam and Lucas fuel line cleaner/ethanol treatment. After three tanks of that, I ran tank down till low fuel came on, kept driving, and no more shudders/jerks and ran great while low fuel light was on.
OK...decided to fill tank with Non ethanol gas this time (not Shell gas), added Sea foam and Lucas fuel line cleaner, and shakes, shudders and jerks all the time now.
Before no check engine lights came on but for once when I romped on the pedal once to blow it out, but it went off once I let off. Today going to work, entering traffic, engine light came on, blinked and stayed on. Truck now shudders and jerks all the time when I give it gas, and can only drive like Paw Paw to keep if from doing that.
Local shop ran test and #7 cylinder is not firing and two lean fuel notices. It will be Tuesday before they can check and if needed, replace coil on #7 cylinder.
I'm thinking of installing a new Fuel Pump Control Modulator as per a thread I read here, but only after they check/replace the coil. AND ALSO...turning the OD off did stop the shutters/jerks.

06 with 5.4 and AT. It shudders in overdrive during light to no acceleration. I was told it was the converter. I was also told by a technician in a trans shop that the Trans-X additive for hypoid oil in a posi-trac was ok to use even though the back of the tube says "Not safe for automatic transmissions". Do this is accurate or if the guy was just blowing smoke?

I have a 2004 F250 with a 6.0l Diesel and a 5 speed automatic. The truck is 4 wheel drive. As far as I know it is completely stock and has 236,500 miles on it. I thought that I was having stiction issues because when the truck is cold and when driving ~55 mph (1500 rpm) in 6th, the truck shudders until ECT gets to about 150F. This is at a constant speed, when accelerating or decelerating it doesn't shudder. Today I held 40 mph (1500 rpm) in 5th and there was no shudder. I don't know the TFT the shudder goes away at because the epiphany about the transmission was today. Once warmed up there is no to very slight shudder and only around 55 mph (1500 rpm). Above or below that the shudder goes away.

I was driving my truck and I heard a noise around the front drivers side wheel area, like a loose center cap. I got home and jacked up the wheel and grabbed it, it wiggled side to side and u and down. Would that be wheel bearing or tie rod end or something else

How to tighten the drivers side mirror? It's rattling around and driving me nuts. It's loose at the pivot point not the door mount. It's the power/folding version. I looked at it but can't figure out how to tighten it. There is a little plastic access panel on the bottom below the pivot but there doesn't appear to be a nut or anything to tighten in there? Maybe I missed it?

My driver door is just loose enough to rattle on bumps and it's quite annoying. I've loosened the striker and tapped it in as far as it'll go with the hammer and it is still not tight enough. I need about 1/4 inch more and that's about how worn my striker is. Obviously I need to buy new a new striker based on the wear, but am I the only one with strikers wearing too much to be adjusted and causing rattles ?

My 2007 F150. That jack wobbles in the hole and, when I plug in a cave, it does not make solid contact. What I am wondering is, does that little panel on top of the dash pop out of that hole to give access to the jack? I am wondering if I can tighten it and re-tension the contacts if I can just get behind that panel.

I have with my F150 5.4 liter truck. I had the spark plugs replaced about 1 year ago. since then I have had 2 plugs back out and come loose. I would smell a faint gas smell first that would tell me know that it was happening. the first plug was if memory is correct either number 8 0r 7 on bank 2. this time its number 2 on bank 1.
I hope that my mechanic just did not torque the plugs correctly and all I have to do is tighten them. If that's not it. Could the spark plug holes be stripped and have to be re-threaded? And if so how us that done?

I purchased a 2006 Lariat crew cab 4x4 back in early feb... since then, I've been on the Interstates a little more than usual ( traveling back home.. dad had a surgery 3 hours away) . . . anyway, the truck gets kinda loose feeling when coming onto bridges and off of them, almost like the back end is swaying and the tires are leaving the ground in the front.. my steering wheel gets loose for a split sec. When I bought the truck I wrote this off as bad tires.. it had some over inflated BFG stock looking tires and where too small.
now, I have new wheels and new tires one size up on the tire. While the ride is great off any bumps.. the second I hit a bump it gets squirmy... I had a guy look at the shocks, he said the seemed ok.. could it be possible to have the wrong shocks on ?
My 2004 crew 4x4 did not do this.. so I know its not a characteristic of the truck. Tired of feeling like I am driving on ice... which is how I lost my 04. My first guess was the Shocks... I bought a level kit for my 04 and never got to put it on... so, it may work out to replace them while I am at it.

Whenever I am driving 60 km/h or more a loud noise seems to come into play. The noise sounds like a really loose ball bearing spinning. Then sounds like a turbine slowing down when going 30 or under. The only issue is the noise does not go away until the truck shifts down into 1st gear. And when doing so the truck jerks enough for everyone in the vechile to feel it. This problem only seems to come when it's rainy or slushy outside and even then does not happen very often. I have had the truck to ford and another mech. Nobody can seem to pinpoint the problem. 2006 f150 5.4l ....

I have a 2008 Saturn Outlook, 88k miles that shudders at 35mph when accelerating. Does not matter if the car is hot or cold. This problem (there are others) started after I had my tires aligned. It does not pull to the left or right it just shakes and shudders at 35 mph and goes away. I thought maybe it was the spark plugs, but darn if this stupid car company did not build this so you (the regular folkd) can change their spark plugs. Have to remove the exhaust manifold etc. or pay a mechanic to replace them. After this started I had to have my water pump replaced, while it was in the shop I had them run a diagnostic and nothing shows up except the water pump issue and that my timing cover needs to be resealed.

I had suddenly developed a case of P/S high frequency SHUDDER, on my 99 Ranger, when the steering wheel was moved to either side of center. The fluid level & condition were A ok!!!!, I have kept it changed, so it's never gotten dirty. I removed about 4 oz of fluid from the P/S pump reservoir & added a like ammount of SeaFoam Trans Tune, to bring the level back up to full. In about 10 min 90% of the shudder was gone, After a 40 mile fishing trip to the lake, 99% was gone. The next day, after another 40 mile drive to the lake, fishing, it's ALL gone. So if your experiencing P/S shudder, try a SeaFoam Tans Tune treatment & a fishing trip or two, maybe it'll tune both of you up, did ME!!!! LOL BTW this is the second time the Trans Tune has worked on a P/S sticking/shudder problem, worked on my 94 Taurus two years ago, when I was experiencing a "sticking" problem with the steering wheel turned WELL off center & it's still ok. So if your having that kind of P/S problem, don't be afraid to try the Trans Tune, & a fluid flush & change, if it's dirty, like the Taurus fluid was, it just might WAKE things up.

My 2008 XLS has 172,000kms on it and has been having a vibration problem. Specifically, the gas pedal vibrates and the whole car shudders when it is between 55-80 km/h and in 6th gear. The shudder/vibration occurs when the car has to drop a gear to accelerate. After it downshifts, the vibration is gone. It has been happening for the past few months. The vibration did go away for a while after I changed the brakes. So, not sure what could be going on there!

I have had this truck for a few weeks. I do not have a good history on this truck. the guy I got it from did not seem to know much about it. He got it from a local retired painter. It has 230K on it. It seems to run and start OK. So I got up and decided to take the truck because I'm trying to determine if it reliable or not. Its about 45F. It starts fine and idles fine I'm cleaning the windows.
About the time I'm done the idle speed slows sightly it shudders a bit and stops! I try to restart is a bit. No sign of life I take a car to work. After work it's about 68F, I open the fuel filter to check for fuel. That makes a mess! I clean it up the mess and she fires right up. I take her for a little spin everything seems fine. The CEL never came on. What do you think? I figured fuel from the way it died, but after work she fires right up. I do not want to get stuck on the way to work!

My 04 F350 has a bad shudder when slowing down between 30 and 10 MPH. Not so noticeable at other speeds and almost nothing while speeding up. How to fix?

2012 6.7l CC SB SRW 4x4.
Truck has 9700 miles on it, bought it in December of 2012. Twice in the last week, when at about 60 mph on a flat road, maintaining speed with virtually no wind, there is a slow, gradual shudder from the rear wheels. Both times the truck has been on cruise control and if I add power, the truck does not accelerate and the shudder continues to increase. If pull power either by brake or canceling cruise, it stops and the truck performs as expected.
I have yet to have the time to reproduce this. My only hope is if the dealer is already aware. I plan on trying to reproduce it at some point with hopes of having something tangible for the dealer.
