I have this bucking a jerking when pulling my Sundowner LQ horse trailer, primarily in the 40-50 mph range. I can let off throttle and it stops but resumes unless I feather the throttle.... 2008 f 350, 4WD, 6.4, 48k miles....
View 1 RepliesI just bought my 2015 F350 long bed Platinum a month ago, and the first trip with my 12,000 lb. 5th wheel had a vibration when starting out, but only from a stoplight with some acceleration or an incline, not at level slow startup.
View 6 RepliesMy 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 2011 F350 is shaking like a wet dog, all the time, loaded with a trailer and empty. It's the whole truck, not just the front end or rear end. It'll shake a Dr Pepper flat in 10 mins. No one can figure out why. Maybe y'all can think of something.
Here's what we've done
New tires, balanced
Alignment
Replaced ball joints and sway bar
Replaced carrier bearing
Replaced passenger front hub that got mysteriously locked and henceforth destroyed.
Replaced all 4 shocks
Where to look next?? Guess I should mention is 4x4 dually with 177,803 miles.
I recently purchased this truck and have towed a couple of times with it. It has 98,000 miles and I do not know if the automatic transmission fluid has been changed. Should I have it flushed or drop the pan and change it? I have a lift so doing the change is no problem, although it might be worth it to pay a transmission shop to do it.
Also, I hear what appears to be like a heat shield rattle or something that sounds kinda like an exhaust leak during loaded acceleration. What to look for to locate the noise? One last question, the air bag light is on sometimes then off sometimes. Any known air bag light issues? I love the truck, hate the gas mileage!
I've got a 08 f250 ext cab long box with the 5.4 gas. I know I know 3/4 ton gas. Trucks got NO power at all loaded and unloaded and really bad fuel mileage. Driving like a grandpa in town I'm getting 7mpg on the hwy unloaded I get 9 or 10mpg loaded on the hwy the trucks working way harder than it should and getting 6mpg.... I'm wanting to swap the 5 4 for a 6.0. Reason I saw 6.0 is my buddy's done egr delete. Bulletproof oil cooler head studs and a edge with attitude chip and has great power and reasonable fuel mileage. How hard is it going to be swapping the motors.
View 10 RepliesMy truck seems to shudder between 40 and 60 mph when it's in OD. If I turn off OD it seems to go away with the increased rpm's. Although I can't be sure if it genuinely disappears or if I just don't notice since I'm at 2100 rpms instead of 1500. Trans fluid is clean. Is this a common problem in these trucks? Just filled up from flat E the same day air temps about 4 deg. Truck was fully warmed up. Does this sound ignition related, tranny or fuel related?
View 14 RepliesDriving into work this morning, I came up to the first stop sign before I get on the "freeway" and noticed a weird vibration. As I slowed to stop I could have sworn it felt like the engine was being lugged, the same feeling you get in a manual when you try to come to a stop without using the clutch. I thought for sure the engine was going to die. The engine RPMs dropped to about 800-900 RPM and once I got to a complete stop the RPMs went back to normal.
It seemed to do this every time I came to a stop. Could my torque converter be locking up and not releasing as it supposed to causing the lugging sensation I'm getting? The truck accelerates fine and idles fine once stopped, but when slowing I get that weird vibration and maybe the lugging sensation is just in my imagination and has nothing to do with the engine.
I do have a vibration from a missing wheel weight, but that's usually felt at about 34-35 mph. In addition, I also have a bit of a brake vibration when slowing down quickly, such as when slowing quickly from 65 to turn off the highway onto my local road, but this is a completely different vibration.
So I'm getting a mild to severe shudder depending on load and acceleration rate from stop to 10-15mph... It's worse if I'm on an incline...This has started since having a lift installed...I'm guessing it has everything to do with pinion angle...right?
1999' F350 7.3L 4x4
Crew Cab Long Bed
Truck is 2011, F350, 4x4 CC Long box with a 6.2, 124,000 km on it. Was driving home last night towing my jet boat when I heard a sudden noise from the front end, kind of shudder, first reaction was a flat so headed to the curd. No flat, nothing running hot, no play in wheels, all looked good underneath the front end. Pulled out and drove away, got about 15 km and it happened again, looked all around nothing obvious so pulled out and drove home (25 km) no issue.
This morning wanted to investigate further. Drove truck down the block and heard a definite rotating type sound. Not a grinding more like a scrape sound. After a minute it went away. Went into a parking lot and drove in tight circles but no strange noise. Found that the auto locking hubs were not working but hub would lock in manual. No strange noises with hubs locked in either.
Jacked up truck rotate front wheels, no sound and no play or wiggle on either side. Pulled the hubs and the passenger side had water in it. Hub was not rusty but it didn't look as good as the other side. Not sure how water got there as I have never driven in water, although I am not original owner but have had it two years and put 25,000 km on it. Could the water have gone in deeper and caused a bearing to fail?
2007 F-350 4X4 King Ranch... I have the 6.0 diesel. I am on the road to Houston, Tilden and San Antonio TX, and I am noticing a whistle on acceleration. I can change the tone by how hard I push down on the accelerator. I thought it was a radio issue and turned the radio off and got no change. Turned the a/c off, no change. Down hill or coasting, nothing.
View 3 RepliesI just purchased a new 2015 F250 SC 8ft bed 4X4 2 weeks ago. I am experiencing a vibration on soft acceleration (I feel it through the floor), by that I mean when there is power going through the driveway, not coasting. I plan on making an appointment with the dealer. New F250 SC LB 4x4 truck.
View 8 RepliesTruck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.
Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.
If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal
If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.
So I've got a 2000 F350 7.3. Just replaced all the ball joints, sway bar end links, carrier bearing, balanced the tires... a bunch of stuff to try and eradicate this weird wobble I have and I just can't seem to figure out what it is.
The wobble happens at and around 35mph, and then once I break 70mpis on the speedo (I have a 4" lift and am running 35's so it's not actually 70). I've experienced death wobble before in a jeep I had, and it is nothing like that, and I can't see it being driveline related but I could be wrong.
2015 F-350 diesel purchased in Sept 2014. When moving slowly such as turning a corner and I have to let up on the accelerator momentarily, when I press down again there is nothing for an unsettling period of time, maybe 2 seconds, as though the engine died, but it didn't and it always comes back. Is there a firmware programming update for this?
View 3 RepliesMy 2006 F350 is giving me grey hairs. I'm trying to figure out what's going on with it. I have been getting an occasional (more often than not) grinding noise from what seems to be the front of my truck. It will do it from a stop, under light, moderate, or heavy acceleration. Doesn't matter. If I let off the throttle momentarily it will stop until it shifts and will grind again through all shift points it seems.
Logic says it's got to be the wheel bearings or locking hubs. I recently did both on both sides to no relief. Because this is an 06 it had a different hub set up then the previous years which I've read a lot of info about (needle bearings). It doesn't make a lick of difference if hubs are locked or on auto. If in 4x4 (ESOF) or 2wd.
As mentioned I replaced both wheel bearings with FORD parts and both locking hubs From FORD as well. (Small fortune). Axle u joints seemed tight. Greased me up but no play.
I have a 2000 F350 7.3 2wd Dually - that only only produces cold air conditioing on hard acceleration only stays on for a few minutes then falls away.
The temperature is cold when its going. I've checked the levels and its gased OK. There is no voltage to the clutch on the compressor when it is not working. So I take it, that it isn't the clutch shim/spacing.
If I accelerate hard it comes back immediately. Whether I am going slow at 1500rpm or doing 70mph at 2500rpm - Uphill or downhill. Its seems to need a substantial amount of Turbo boost for just a few seconds to turn on.
I actually bled the system a little and its made it worse. Stays on for a shorter time and isn't as cold. However the low pressure side is still on the high side at 50psi when running.
Its done this for approx 2 years and its getting worse.. And now its really hot outside.
2003 F350 5.4, 4R100 trans.... I've had this truck parked for a few years but want to get it into service for farm use.
In park or neutral, it revs great, idles a bit rough but not terrible. But in drive under load it I can't get it above 1500rpm most times unless going downhill, and then it shifts very late, and I have to get it up to 3500rpm and then let the throttle off to get it to shift. It does better in 4Lo with shifting, but it's still very sluggish.
Now it says to check fluid level in Park at idle. When I do this, I just get fluid on one side of the dipstick, not a full dip as you'd see on an oil dipstick. And the wet on the fluid goes up past the hash marks quite a bit. I'm use to seeing the dipstick get oil all the way across, and then a bit higher just up the edges, but have always read it at the full cover point.
I suspect low fluid, but I'm not really sure with the way the stick reads. I was thinking of draining it all and then filling to spec as per: [URL] .... but have a long drive to go get MerconV.
2008 F250 Crew Cab 5.4, 79K miles, had new brake pads installed at 40K miles. Recently, I noticed front end shudder and some pedal pulsation while braking. It started kind of sudden. My first thought was a warped rotor.
When I took things apart, I found passenger side front rotor was cracked and the caliper pistons were rusted and falling apart, the old pads were only worn about half way. My thoughts on a bad rotor were confirmed, and then some.
I replaced the broken caliper, both front rotors, installed new pads on all four wheels, and bled the brakes. To my surprise, the brake shuddering did not go away. I'm stumped.
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.
View 6 RepliesI drove my pickup on mostly dry pavement the other day with it in 4WD and the hubs locked. I got a bit of shimmy/vibration which quit after about a mile. When I got back on ice, the 4WD wasn't working. I assumed the transfer case or locking hubs had failed. Today I got it up on jack stands, put it in 4WD, and locked the hubs. Everything seems fine. What might have happened when I couldn't get 4WD to function.
