Ford Super Duty (1999-2016) :: Vibration Mostly Noticeable While Under A Load Like Climbing A Hill
Jun 17, 2016
My current 08 duty was bought with what I believe to be a procomp 6" lift modified to an 8" lift. The 100 mile drive home after buying the truck showed a tiny "hop" in the rear. I ditched the 37s for some new 35s. Still a tiny hop, mostly noticeable while under a load like climbing a hill. I pulled the rear driveshaft and had it fully rebuilt with a new carrier bearing as well. Still gots the hop? The truck has a carrier bearing drop bracket but I think it may be insufficient for the lift.
The rear driveshaft still has a slight bend in the middle of where the two driveshaft pieces connect. Are the 2 piece driveshafts on your 8" lifted trucks sitting straight with each other or do they have this bend as well?? I am thinking if I get a bigger drop bracket it may cure this slight hop I have? Lots of lifted trucks where I live but they are dam near all shortbox with 1 piece rear shafts so I haven't been able to find one to compare. By the way, my truck also has pro comp rear traction bars..

I have begun to notice a vibration when I am in first gear starting out with a bit of a load. The vibration goes away as I gain speed and the load reduces. None at any of the higher gears. If I take off real easy and allow the truck to gain speed without pushing it, the vibration does not exist. The truck is the one outlined in my signature. It is equipped with a 3 speed auto with overdrive. I am thinking this could be a U-Joint that might be starting to go out.

2006 fx4 f150 5.4 flex 52,000 miles ... Just got home from a 800 mile round trip vacation, seems I've developed a miss or a tranny problem. The truck runs/idles fine, shifts fine, everything is as normal. Except maybe 12 times while under a load, like climbing a hill, the truck would "bump" that's the only way I can describe it. I only noticed it in Drive/Overdrive. I hoped I had water in the gas so I added gas treatment at 2 fill ups, still seems to do it occasionally. Where to start? I'm going to get a fuel filter today, the one that's on it only has about 12k on it....

My 2015 F-350 Super Duty has a noticeable vibration between 5 and 15 mph when accelerating with my 5th wheel. The 5th wheel is heavy--around 14000 pounds. The pin weight is heavy--around 3000 pounds. The Owner's Manual says on page 191 "When driving with a trailer or payload, a slight vibration or shudder may be present due to the increased payload weight..." (This was brought to my attention by my dealer.)
Seeing the thousands of F-250 and F-350 Fords pulling 5th wheels out there on the road, I wonder how many have this "slight vibration or shudder" and what they have done about it.

My F250 6.4, 3.73 Crew Cab Short bed vibrates when accelerating from a stop with my 5th wheel on. The 5th wheel weighs 12K. It is a medium to high frequency vibration that is felt throughout the entire truck. It continues through the shift into 2nd (TorqueShift Tranny). The harder you accelerate the more you feel it.
It does not occur if truck is unloaded and you accelerate at full throttle. Is this normal or should I get it looked at?

I have a 2000 f250 crew cab short bed 7.3 on a 6inch bds lift and 37 inch tires. When I accelerate pretty much any load above 1200 rpms I can feel a vibration, kinda feels like it may be coming from the front left but I'm not sure. I have heard that a wheel bearing going out can cause this, would this maybe be what's causing it?
I thought wheel bearing because it kind of sounds like there's a howl when decelerating, probably when accelerating as well but the trucks too loud and I can't hear it. or also have heard motor mount gone bad, I've also heard ujoints but the ujoints were done this summer. the front ujoint is bad but the front driveshaft shouldn't be turning when out of 4x4 and hubs unlocked.

Ok...not sure were to go with this or how to explain it, while climbing a steep paved hill at 5-10 mph I get a rumbling vibration and noise. If I were to guess almost like axle wrap is causing the U Joints to bind or something. Runs and drives fine other then that. If I put it in 4x4 it does not happen, only seems to happen when wheels cant slip while climbing hills at LOW speed.
Don't notice it if climbing a dirt hill. There is a hill at the kids baseball fields that is steep and paved that its really bad on, way to busy right now to play on it to see what's happening. Tranny was looked at and oil changed.
New BDS 4" lift - had same issue prior to lift, though stock springs were worn.
Searched the form but really didn't come up with anything at this low of speed. While in Wisconsin the resort we were at the paved hills were so steep it felt like something was going to break. Put it in 4x4 and it was fine. This was with stock leafs.

02 f250 SD 5.4 zf6 manual xcase ext cab long bed...
When I'm cruising down the highway it's most noticeable. 5th gear anywhere from 65mph+ I'll let off the gas and it'll make a "errrRRRt" until I press the gas again. I've recently installed new :
- Front u joints, ball joints, hub assemblies, rotors, calipers, pads
- Rear drive shaft u joints
- Front diff fluid
- Trans fluid
- Tcase fluid
- 4" zone lift kit
All of these things did nothing to effect the noise. it seems to be coming from between the clutch and rear shaft (either clutch, trans, tcase). I don't think it is a motor noise or suspension noise.

When running up through the gears under normal acceleration I can feel almost a double shift in 5th gear. It doesn't occur using tow/haul so I assume it is the TC locking up. Everything else seems fine. Truck has 9k miles, mostly towing. 2016 6.2 ....

Drivetrain noise I cannot diagnose. I have a 2002 F350 diesel and have noticed over the past couple thousand miles a noise from the drivetrain that is hardtop identify. It is not brake related ( new and unaffected by brake application) and not rpm related. Most noticeable at around 50mph. Not tires and they are new and noise persists.
Front end has been apart for new hubs, brakes, rotors, wheel bearings. Noise continues. It has an oscillating quality and is somewhat like a lower pitch whine which gets more prominent as speed increases. Wondering about bearings associated with drive shafts? Are there some things I can check underneath to diagnose the issue?

Decided to try a new wheel to see if I can stop the surge during hill climbing with our 5er. Old wheel looked great with no dusting or nicks. New wheel sure has a whirl when it spools up, but sounds cool. Haven't pulled trailer since swap yet. Truck still only has 85k on the clock.

I have a 99 explorer that stops blowing air when I get on the gas or climbing a hill. The motor is still blowing but it stops air coming out the vents. What could be causing this? It works fine other than that.

My F250 is displaying error messages for the hill descent/advance trac yet again. My truck was in the shop over 7 times about 6 months ago when my instrument cluster would go crazy. Every warning possible on the display, and once you killed the engine it wouldn't start until the dealer cleared the codes...once they flew in an engineer he fixed it within a couple hour timeframe, and I thought that nightmare was over.

I have a 2001 F350 with a 7.3 diesel and automatic trans. I purchased it about 100,000 miles ago. It is all stock as far as I know. The mileage on it was about 14-15 on the road and I decided to put a chip in it. I was somewhat leary of putting too much power to this old of a rig. I put a TS Performance chip in it. It seems to have more power. I am towing a 30 ft. Gulfstream Seahawk I think around 10,000 lbs. When I started up a hill it made a different noise like a screeching noise when I pushed it. When I back off a bit the noise goes away. When I put it back to stock setting the noise is not there just the normal downshift and increased RPM. Not sure how to describe the noise but sounds like a metal bearing type noise. I get the same rush of air or what ever that sound is when it changes back to a higher gear. Is this sound normal or what might it be. It sounds normal when not pressing it.

2003 7.3 Sd Has a flat spot from 2700 - 3000rpm especially when it changes down, say going up a hill , if I decelerate and let it change back up it will pull again but if I leave it changed down it will not rev anymore. No CEL , put it on the scanner , only code that came up is " intake temp Low " which would not effect it. Have just installed new up pipes , new HPOP hoses , in the past it has had a new IPR and HPOP . It had this flat spot before and it would bring up low boost pres hence the up pipes . Have checked all flanges and intercooler boots etc.

I have a 2006 f-250 super duty with a 6.0 and auto trans. I was pulling a trailer with about 5k of vehicle on the trailer.
Problem : after a long trip on good roads, I had to pull a steep hill. climbing the hill i did not shift into tow mode and all of a sudden my engine raced up to about 3k rpms and seemed to either shift to low or ( maybe ?) the Governor may engaged ?
Anyway I made it to the top of the grade and it seemed to be fine from there.
Question Is the trans broken, or did the computer maybe try to protect the trans ? It seems to work fine still?

I own a 2012 F350 dually King Ranch with 6,600 miles on it as of today. I noticed that on slight inclines, I can see and feel the hill start assist feature activating and working as before. I was not towing anything today. Starting today though, I hear this loud creaking noise both in forward and reverse directions with quite a bit of shutter from front of the truck lasting one to two seconds as I transition from the brake to accelerator. I checked the front hubs to make sure that they are not in locked position. I tried activating 4WD auto mode, then deactivate it to 2WD mode as I watched the diagram/figure on the dashboard. Nothing would make the loud creaking noise and shutter go away. Is there anything else I can try, or should I take it back to my Ford dealer again (now for another different reason. I had problem with injector #8 failure with CEL come on earlier this week which appears to be fixed for now)???

I have a 2000 F350 7.3 4x4. It began giving intermittent tow/haul flashing light, when going up or down hill but would clear and drive next time truck was cycled off/on. No ABS lights and code reader generated P0720 for the output speed sensor, now I can get it to generate just driving slowly fwd and rev a few times. All of this has been in the last few days.
Truck will stall if I take it up a slight incline with the fault. I replaced the sensor on the top front of the 4r100 transmission and also replaced the sensor on the rear differential after giving up on looking for an output sensor on the transmission. I know the 2WD transmissions have an output sensor but is there one on the 4WD version? I have read several past threads discussing the P0720. I am hoping to confirm what sensor I need to be looking at and where it is located in this application.

I have been reading several past post regarding the misfire while in OD and going up a small hill with light acceleration around 45 to 55 mph. Everything points to the COP so I replaced it today. Still getting the code after 20 minutes of driving around. My truck shudders and looses power. I can either let up on the throttle or hammer down on it to eventually smooth it out and everything goes back to normal.
Check engine light flashed but didn't stay on. My scanner does report misfire on cylinder 7 (P0307). Haven't owned this truck very long so I don't know much of it's history except OASIS report shows nothing alarming. Guess next step is a new set of plugs.
Another first today, is the tachometer is stuck at 4500 rpm. Shut the truck off and let it sit for an hour, then went back to start and tach. acts like 4500 is the new zero and running engine at 1000 rpm now indicates 5500. 2007 F250 SD 5.4 ....

I was running tire chains on my front end and broke the wires going to the wheel (I know ,not smart) . Immediately Service AdvanceTrac, Hill Descent fault, ABS light came on. I took it in to a shop and they repaired the wires but lights are still on and won't clear. Buttons on the dash wont work either. Messed up the sensors maybe?

My current truck is an early 99 F250, 7.3L diesel, CC 4x4(manual shift transaxle) auto transmission. It is basically stock, with the exception of a hutch/harpoon and a new fuel pump over the winter, an AIS intake. I have a magnaflow exhaust kit in the garage along with bellowed up pipes but have not installed them yet.
Here is my issue. Several times over the last 2 years, the truck will pull a load, or long trip, and with complete randomness, the engine will feel like it has shut off, there is usually a jerk or two, and the truck "restarts" itself and continues on like nothing happened. Last year we drove 1.5 hrs from home with the boat in tow, driving up Snoqualmie pass, and it died completely, no restart. We had to be towed home. It started right up at the shop, so no real clue of what happened.
When this happened, I had the fuel system checked for pressure and replaced the engine fuel filter, and all was good. I also had the Cam position sensor replaced/updated to the new grey sensor. Shortly after, I had the minor jerk/stall occur again, so I replaced the fuel pump and did the hutch/harpoon mod to ensure there wasn't an intermittent fuel pressure loss and that the in tank filters were not clogged.
Last weekend, i pulled my boat to Oregon, and the same "hiccup" happened as I was about 1.5 hrs into my trip. it was fine after that the rest of the 4 hr trip. We also drove back the same route and had no problems.
