Ford Super Duty (1999-2016) :: 2003 F250 - Vibration At All Speeds And In Rear End When Braking
My 2003 Ford F250 V10 seems to have a vibration, sometimes at all speeds and sometimes at freeway speeds. I replaced front hub assemblies and ball joints and rear calipers last year. When braking i have a vibration in rear as well, which I think is from uneven rotor but can it be causing my vibration? Also sometimes I can smell hot brakes from the rear.

The other day I pulled into the parking lot put it in park and let it idle for a couple minutes, it stumbled and when I started driving off it was missing. I pulled the valve covers off and check the connection.. I drove it home and it had a bad misfire at 1500 RPMs. The truck shook violently at that RPM but when I got it up over 2000 smooths out..

I have a 2011 f250 6.2 cclb and it shakes around 70 to 75 mph. Not terribly but enough to annoy the crap out of me. Now I have put new tires on it recently, new Rancho 9900 adjustable shocks, I have it aligned regularly and tires rotated and balanced every 5000 miles or so. I have had two dealerships look at and my local shop and they can't see anything visibly wrong with it.

2014 F250 SuperDuty 6.2L gasser, x-cab long bed work truck. 105k miles, original owner, 1 driver, mostly highway miles, well maintained and super clean truck.
First issue occurred at 83k miles, Aug 2016. Warm summer day climbing I-70 in CO, slightly loaded, and just entered the Eisenhower tunnel (11,150' altitude). Lost power, no RPMs - not running, I put it in N and rolled as far as I could. Hazards on and no-where to pull over, hugging the wall and blocking one lane. Power OK - will crank, no fire. 1/3 tank on the fuel gauge and >100 miles distance to empty on the trip computer. Tunnel rescue shut down traffic and pushed me out into the daylight.
After waiting an hour to fill our paper work for disabling the interstate tunnel I returned to the truck which quickly started. No symptoms, no lights, no codes. Topped off the fuel tank after a easy 15 mile drive downhill. Drove another 800 miles symptom free to my destination and checked it in at the dealer. At this time a check engine light had finally illuminated - PO420. I shared the story of stalling out at highway speeds with the Service Writer. Dealer replaced the cats, confirmed fuel pressure OK, computer condition OK, serviced the trans (at my request).
No symptoms reoccurred during the next 20k miles until last weekend. 105k on the OD now. Heading to Flagstaff, AZ on I-40 in similar conditions. Hot, AC running, climbing in elevation, slightly loaded, running on the bottom 1/3 of the fuel tank... Died while cruising at 79 mph. Well, at least this time I wasn't in a tunnel and had a shoulder to pull off on. Deja-Vu - full power, radio on, no engine lights, gauges normal, fuel reads over 1/4 tank, >100 miles till empty on the trip computer - won't start. Cranks, but no fire. Some sputtering during start attempts must have triggered the next trouble code.
Opened the hood, removed the gas cap, let it vent and cool for about 30-40 mins while I took a walk. Returned to the truck which easily started and let me drive to the next fuel station, 30 miles away. This time the check engine light stayed illuminated. It took 24 gals of fuel. Drove 3 more hours and almost 200 miles without symptoms - check engine light still illuminated keeping me curious and fully alert along the way.
Got the codes pulled at a parts store that was open on Sunday. PO300 & PO301. Random misfires and cylinder 1 misfires. Sounds consistent with poor fuel supply? Spent the rest of the day searching forums for any clue to this highway stalling. All I came up with was to clear the computer - disconnect battery, turn lights on, wait 15 mins, reconnect battery, start engine, apply brake, drive, etc. This and another full tank of gas gave me enough courage to set out on my trip home.
Next occurrence was just outside of Santa Fe, NM. Similar conditions again: Hot day, AC kicking, Interstate travelling about 80mph, slightly loaded, climbing in elevation, fuel tank just below half - stalled out. Repeat previous learned routine. Open hood, vent gas cap, walk it off for 30 mins, return to truck, start it up. Drive to next town and top off with fuel about 30 miles away - only took 16 gals! Made it home 4 hours later without stopping. No repeat symptoms, no check engine lights.
The next day a code - PO420. Catalytic efficiency below threshold.
Quick recap:
6.2L gas engine stalling at hwy speeds.
Cruising between 65-80mph
-Interstate travel - no stops between last fillup and stall.
-Warm weather, AC on
-Running on bottom ~1/2 tank
-climbing in elevation, slightly loaded
To clarify: slightly loaded - no trailer, maybe 1,500 lbs bed cargo, mostly wind drag. The most I have pumped into the fuel tank is 29-30 gals or so. I assume I have the 34 or 35 gal tank. Never seen the calculated "distance to empty" below 40 miles.
Ford Super Duty (1999-2016) :: F250 - Door Corner Rattle At Highway Speeds
My factory-ordered 2016 F250 CC SB 6.2L 4X4 3.73 is about 6 weeks old. Driver and passenger side door rattle noise (in upper back corner) at highway speeds (65-75 mph) has gotten progressively worse over those 6 weeks. See attached video.
Trying to determine if this is caused by:
Door seals: the temperature here in Iowa has dropped from a few weeks in the 90's to the now in the mid-60's.
Could the temperature change have caused the seals to change shape/structure and result in the rattle/noise?
The exterior seal between the front and back doors (attached to front of the back door): mine seems a little loose on top, but nothing that would cause this kind of noise.
Ford Super Duty (1999-2016) :: 2003 F250 - Moaning Noise From Front End At Highway Speeds
I noticed a moaning from the front end a few weeks back and it seems to be slowly getting a little worse. It is only noticeable when I'm accelerating or maintain speed, but as soon as I let off the accelerator and start to decelerate, it goes away. Sometimes, when the truck hasn't been driven for at least a couple hours, I pull away and there is a really noticeable sort of "clunk clunk clunk" but then it goes away and it just moans. I can also hear some noise from the front end at highway speeds, but of course it is hard to hear much else other than engine and road noise from the cab. It's a 2003 F250 with a 7.3 and four wheel drive.

It's a 1999 f250sd 5.4l auto. Has code p1747. Truck shudders and almost dies when you drop it in gear, put it back in park idles fine. I have read all the post on here about this and checked wires from trans up to pcm look and test well. Tested plug c1048 wires with the digital meter to body ground with battery unhooked and got 6.66k ohms on pin 11 circuit 925, 421 ohms pins 1 and 12. Plugged c1048 back to trans checked 925 w/y wire at plug c103 got 9.1 ohms back to trans. Is the EPC solenoid bad or is it pcm? I think its epc but want to verify before i take trans apart.

250 2006 Superduty v10. Codes p2106 and p2135 ... Only occasionally when coming to a stop it shudders like it would stall. It happens for just a few seconds then ok again but wrench light comes on. After the next shut off and start the light goes out. I had the throttle control position sensor checked and they said it was ok. Got a software update at Ford. I hate to just start replacing expensive parts. I have about 60000 miles and it is a great truck otherwise.

My 2010 F350 shudders when turning right. From what I read it could be the auto locking hubs not dis-engaging or sticking in the locked position. Tutorials show it's pretty easy to pull the auto locking Hub out taking out the three screws holding it in place. My questions is what type of grease do I need to apply to the auto locking hub once I have them out and determine that is what the issue is?
View 13 RepliesFord Super Duty (1999-2016) :: Clunk While Accelerating And Braking
So my '99 F350 4x4 is making a clunking sound and there is a distinct jolt in the truck while this is occurring.
Symptoms: From a stop while accelerating, there is a distinct jolt and clunk. The best way I can describe the feeling is like something isn't tightened down all the way so there is a split second while inertia is generated and the "looseness" catches up to the acceleration.
When stopping, the clunk and jolt is generated when the truck comes to a complete stop. When the truck rebounds backwards a bit because of the suspension pulls it backwards after stopping, you will hear the clunk again.
I replaced the ball joints a week ago an a wheel hub bearing on the right side. I don't recall this before these repairs, but it may have been making this noise. I was more focused on the grinding from the wheel bearing so I may not have noticed the clunk and jolt then.
Where I should start looking for the problem?
Ford Super Duty (1999-2016) :: Rumble With Vibration While Braking
2004 6.0L Excursion Limited 4x4.
I recently developed a "rumble" with vibration while braking. I describe it as a rumble because I associate it to a similar sound, cadence, and feeling as if you were slowing down on the rumble strips you find on the side of the highway.
It is mostly only noticeable at lower speeds. I know the sound and feeling of warped rotors, but this seems different. If it makes any difference, one issue I've been dealing with is that the front transfer case does not release when 4x4 is off and hubs are in AUTO.
Ford Super Duty (1999-2016) :: Shaking When Accelerating Or Braking From About 40 - 60 MPH
Truck is a stock 2001 f250 7.3 with 205,000 miles. When accelerating or braking from about 40-60mph it starts to shake a little bit. When braking it shakes a lot more from 60 down to 40. But the faster you speed up the less it shakes when taking off. Looked at everything underneath is tight, and it has stock a stock steering stabilizer. Would a new stabilizer fix this you think?
View 7 RepliesFord Super Duty (1999-2016) :: Odd Braking / From 5 To 0 MPH It Almost Feels Like Slide On Ice For A Second
First off I want to say my truck isnt throwing any codes, nor am I loosing any pressure on the brake peddle. What is going on is my brakes are working just fine I can stop from any speed and my brakes are performing just fine until I slow to about 5mph.
From 5mph to 0mph it almost feels like I slide on ice for a second, and you hear a sound almost like what you hear when your ABS kicks in. I will feel a slight fluctuation in the brake peddle and then my truck comes to a stop. It is the darnest thing. One mechanic I spoke to said he thought is was the vacuum system, another thought it may be the brake sensors....
