I have an 04 6.0 F250. I am having a shaking between 1500 and 2500 RPM around 45 - 55 MPH. I have no guesses what is calling this, but the truck runs fine otherwise.

I was running my 99 F250 SD with the V10 around the DFW area pulling a car hauler with a Jeep on it. The last 50 or so miles on the way home she started shuddering at a constant speed unless I turned off the overdrive or I was accelerating or slowing down.
She's never given me any issues but this is bothering me. 4x4...
Ford Super Duty (1999-2016) :: F250 - Vibration Above 70 MPH - Speed Related
I have a 1999 F250 super duty with a mean vibration at 70+ mph. It is a 5.4L manual trans manual 4x4 extended cab short box with around 250k miles on the body and 50k on the motor. It is a one piece drive shaft with the double knuckle at the t- case. it has had a vibration in the drive line since i bought i about a year ago. there is almost zero vibration at 60 mph but at around 70 the vibration starts to get really bad. The vibration is speed related because when i push in the clutch or pull it out of gear the vibration is still there. i seems to vibrate more when winding out in 3rd and 4th gear but that may just be because off the exhaust resonating or something. I have already done u-joints, balanced the drive shaft, put brand new tires on mounted and balanced, replace transfer case output bearing and both front hub assemblies. the vibration feels like it is coming from the trans or transfer case. every thing i tried made very little impact on the vibration. I'm a loss and i don't know what else to try. i know the throw out bearing an pilot bushing are bad and the clutch is well worn so ill be replacing that soon but i don't believe that is causing the vibration.

I have a 1999 f250 SuperDuty with a nasty vibration That begins at about 70mph. The truck is an extended cab 5.4l Manual trans 4X4 with a one piece driveshaft (No mid bearing). The Vibration appears to me to be a driveline vibration that is speed dependent. It is the same in gear, out of gear clutch in or out. I have replaced the wheel bearings/hub assemblies on all four corners, completely rebuilt and balanced the driveshaft the driveshaft, removed the front driveshaft, put brand new tires mounted and balanced on all four corners, new clutch, had the flywheel turned and balanced, and replaced the transfer case output bearings. Pinion bearing feels tight and does not leak.
Also the Input in the trans felt tight when i had the trans out. The truck had the vibration when i bought the truck and still vibrates after i have done all of this work. i did not change the motor mounts because they looked fine. when i bought the truck the tabs on the extension housing holding the trans-mount to the trans were broken so i make a huge "exhaust clamp" to straddle the trans and bolt to the trans mount.
After driving the truck up north last weekend the truck seems to shake going taking of at lower rpm as if the motor mounts and trans mounts are bad. I guess my questions is can a bad trans mount, motor mounts cause this Vibration at highway speed. if so is there a way to fasten the trans-mount to the extension housing without replacing the extension housing. If not what else can cause this issue?
Ford Super Duty (1999-2016) :: 2007 F250 - Misfire At Highway Speed
Have a 2007 F250 6.0 diesel with the standard issues including misfire at highway speed. Assume the bulletproof kit also cures the stiction problem? in reviewing the threads and looking at the vendors, references are made to fixing the oil cooler issue, egr issue, etc., but no one addresses stiction issue directly.

I have a '16 F250 4wd with the 6.7 and approx 3k miles. There has been a strange sound coming from the front end when turning left from a stoplight. It sounds like something slides or shifts and it only happens once in a while. The noise isn't loud but you can feel it.

Truck is an 02 F250 Automatic 4X4, 7.3 PSD.
Cruise control will turn on, will sometimes set speed and sometimes will not. If it does set and work it may kick off at any second or it may run fine. I have noticed it seems to kick off mainly after going over a slight bump in the highway or it may just kick off for the hell of it. Truck has 50,000 miles on it, I bought it new. Also having trouble with the throttle position sensor, it seems to have a "dead spot" at about 58 mph that shows up when I romp down on the pedal to pass on 2 lane roads. Can these two symptoms be related? Both are very aggravating. FWIW it does have the power adjust pedals. Truck is 100% stock, no power chips or other upgrades.
Ford Super Duty (1999-2016) :: 2007 F250 - 2nd Speed For Blower Motor Don't Work
I have and 07 F250 and the #2 speed for the blower motor don't work (hasn't since I bought it) I read that the most common cause of this is the resistor under the hood on the firewall so I replaced that and still no 2nd speed??? Where I look next? Motor itself maybe?

Now that I use my truck as a daily driver I am noticing a vibration under acceleration at 30-35 and constant vibration at 45-50 accelerating or maintaining speed. I have replaced all three u-joints as well as new ribbed highway tires all around and still have the vibration. It seems worse in OD. I have done a little research and am either going to shim center support/machine a new one or have a one piece shaft made and need info on how to successfully gotten rid of this vibe on their truck mainly the amount of shimming required and the final driveline angle. It seems that most posts regarding this issue lean towards the fact that the 45-50mph vibe is normal for my year super duty and that's probably right but I want to remedy problem not "live with it!" (10 mile 45mph stretch to work @ 4AM, vibe bugs the heck out of me!)
Truck is 2000 f250 SC 2wd 4r100 3.73 gear currently 51000 miles.
Ford Super Duty (1999-2016) :: 2006 F250 - Growling Noise That Is Speed Sensitive
I have an 06 f250 that is making a growling noise that is speed sensitive and sounds like it might be coming from the front. I thought it was tire noise from my old worn out tires but with new tires it still maks noise, but tires have pretty rough tread. How can I tell if it could be a wheel bearing? It seems like the noise quiets down a little on right turns. It is kind of a growling humming noise that changes with speed.

2004 F350 single rear wheel with 8" suspension (springs) lift and 37" tires all put on in 2005. Having low speed vibration 15-20 mph on accel and decel. Recently put on thick aluminum rear dif cover and vibration seems to have come since that install. Used Mobile synthetic fluid and 4 oz of Motorcraft antifriction additive and 4 oz of off brand. The Mobile fluid and antifriction have been in my barn for over 5 years in the winter and summer. I just changed the carrier bearing and all U-joints look good. Any chance the fluid and antifriction additive could be causing this? Truck has 66k miles.

I have a 04 f250 with aprox 95k on it 5.4L I knew I was over mileage for a due oil change I haven't been driving it much it crossed my mind, as I am usually very adamant about changing fluids. I went to check my oil and only a smudge of oil on the dip stick. I know this is not good but the truck runs fine, no noises, no knocking, not a chatter from the valve train. Oil pressure was good everything seemed fine did I get lucky? I know it wasn't good I am not going to let that happen again everyone think I dodged the bullet?
