Ford Super Duty (1999-2016) :: Shaking When Accelerating Or Braking From About 40 - 60 MPH
May 29, 2016
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?

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?

I got a 2000 f250, 5.4l, I got a check engine light bout 2 weeks ago and didn't experience any driving issues. The code was p0171, just recently I've been experience troubles idling, if I let my truck idle for about 3 minutes it will want to shut off, also on acceleration the hole truck bumps, feels like I'm in an earthquake. Where I should start with this problem?

I have a 1999 f250 v10 auto. It has 3 miss fires thats im stumped with .. Ive replaced all spark plugs, all coils , I've had injectors out and were cleaned and it still miss fires. I can disconnect the coil and injector on the cylinders and the motor runs the same. Ive swapped the coils and injectors around to make sure it wasn't them. What else could it be? Frustrated I've had the truck for 2 years and haven't figured them out. Ive had them go away for at most a day. Also the truck has a shake at 80 kmh not sure if its from the miss...

My 2004 F350 6.0L v8 has a weird shake when I get between 45 and 55 mph. Doesn't feel like its the tires, feel like the engine. I think I might have the #5 glo plug out. Is that it or could something else be wrong? If it is this how bad is it to drive on.

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.

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....

My 02 f250 started shaking violently until when I accelerated and the mechanic said it was the wiring harness in the computer. He said it was caused because of over revving I think it was just because the harness was old. Is it because of over revving? Will it happen again?

So I have a 2016 6.7L love it but it has this vibration at 65 mph that is worse when accelerating up a hill. It feels like an out of balance wheel but I have had them balanced 3 times. road forced 2 times. My dealer replaced the driveline also. I did a test with 400 lbs of concrete bags in the bed and it was vibration free. It almost is like the pinion angle is off.

2008 f250 standard cab long bed 2wd base model 5.4. This thing has been great for the last few years i i owned it but it developed a shake since i got new tires. My mechanic mounted 4 new Hercules Terra trac at 2's on my 18 inch wheels (275 70 18) and when i got the truck back it was shaking violently at anything over 45. Mechanic says the new tires are heavy and its affecting other things...sounds plausible. So here i am a month later with a New steering stabilizer, all new ball joints, new shocks, new u joints, and 1 new tire (he said 1 of the brand new Hercules had a broken chord). The shake is 80% gone but this truck is still not the same. Anything after 65mph and it has a feint wobbly bouncy shake. I don't think its the dreaded hop that everyone gets on these. I have 2 theories:
1. These cheap tires just suck and will never be right
2. The cheap junk Monroe shocks he put on are way too soft to do anything
so what do i do? Should i get some crazy shocks or will that make this truck even bouncier? Im worried about making it even stiffer than it already is.

2016 Powerstroke ... Bought the truck new and now with 17000km. 1st oil leaking from water separator. 2nd oil leak from what looks like the engine pan,and they have some O rings ordered for it. I have had either huge flares in all gears or slipping whatever you want to call it ? ford dealer finally acknowledged one year after me first telling them of this issue. Especially when the truck first driven in the morning never really fully engaged in gears,it has no torque and all revs. So just got it back from the dealer and its something of a firmer shift but still flares.
But also now shakes violently in reverse since i got the truck back from them. Don't really want to put a tuner on it to get shift firm enough to be practical but voiding warranty. i like the low down torque this motor produces,and in manual mode works well but still flares some. Horrible in auto no torque like driving an old beater with a worn out clutch. They replaced shift D and E solenoid but I don't think this it the issue with my transmission. im thinking of taking the truck to a tranny shop for diagnosis. Could it be line pressure ?

2015 6.7L Super Duty ... I bought this truck 74,000 miles and almost two years ago. About 6 months ago it developed a vibration and a very hard shaking of the steering wheel when (so far) turning to the left. First began when, from a dead stop at a red light, I turned left onto an uphill I-41 on-ramp. Scared the crap out of me and I had to pull over to a dead stop to get it to stop. Happened several times but only on this ramp. Local Ford dealer checked it out 2 oil changes ago and couldn't find anything wrong. Now, 2 weeks ago it did it on the highway at 65 mph on a slow, 80-ish degree and downhill turn on a 4 lane highway in Milwaukee. Again had to almost stop for the wildly shaking steering wheel to return to 'normal.' Am taking truck back to same dealer this Wednesday for it's next oil change and they will check it out again. I pull a 37 foot, 15K pound 5th wheeler and don't need to lose control at 70 mph!!!!!

I have a 2002 F250 with the 5.4 triton engine. Automatic transmission. When I reach 35 mph (sometimes sooner) the truck will shake horribly when I reach lower rpms. It will do this up to 65 mph and then it mostly stops. Completely taking my foot off the gas will stop the shaking, as well as shifting into neutral.
I know for sure that the truck has a cylinder 3 misfire as well as a minor exhaust leak, could either of these be causing it? Don't have the money to fix either of the problems for another couple weeks, is it safe to drive until then or should I play it safe?

While engine braking I started hearing a squeal under the hood , when I started accelerating it became a little louder, I pulled over and when I rev it up it gets louder and has a little rattle sound, sounds like it coming from the turbo....

.I just changed out all the steering linkages due to a lot of slop and worn out tie rod ends. This problem existed before I changed them but I thought for sure changing the linkages would fix it. When I brake hard my front tires wobble very bad. I haven't ever experienced the death wobble that is common in these trucks, but the symptoms seem the same, its just only when I brake hard. I can look at my front left tire while braking hard and see it wobbling. The wheel bearings and ball joints only have about 15k miles on them. I can't tell if the front wheels are moving independent of each other back and forth, or if they are both shaking back and forth together. What might cause this? it's a super uneasy feeling when it happens, especially because whenever you are braking hard there is usually a reason.

I've noticed that my 06 f350 will pump the ABS when pulling in muddy spots, mostly in 4x4? It will even start to cook the pads after a bit of spinning. I'm not doing any serious off-road stuff, just trying to pull random farm equipment/trailers. Do these trucks have some sort of traction control that I don't know about or dose my ABS think I have my foot on the brake all the time?

I have an issue with my 6.0 that no one can figure out. It has been happening for about 3 years. After accelerating hard, motor will rev out like it just popped out of gear. It is still in drive and the edge cts says 4th gear usually. I have to let off the pedal and coast a bit and everything "sync's" up again and works fine. It can happen from a hard launch from a light or get on the freeway. I recently put an ATS transmission in because I figured solenoids were beginning to fail. Still does it. I am running innovative tunes with sct tuner. It had a Suncoast billet flex plate and ATS 5 star converter. I run Amsoil fluid, it is clean, red, and at the proper level. Truck has almost 80k miles. Also 37" tires and 4.88 gears. It has not done it while towing our 35' toyhauler, but I am easy on the pedal when I tow. I recently checked the transfer case and changed fluid to Amsoil. The old fluid looked good.

So lately I have noticed that my 99 F-250 has a bit of a "bump" while accelerating. Think of it as accelerating with a trailer and something is loose on the hitch, making a sort of bump or thump. I talked to the guy at the parts store and he said to put it in neutral and wiggle the driveshaft up and down, side to side.
When I did that it moved up and down, but not side to side, but I'm not sure if that's because it's just positioned that way or what. The wobble was coming from the slip yoke back by the rear diff. Is this something I should be concerned about? Also, I have an ext. cab and short box, 1 piece driveshaft.
Here's a video (a very crappy video at that), not sure if it gets enough info through or not but hopefully you kinda get how much play is in there.

The truck is a 2012 f250 6.2 flex fuel from alberta canada. This isn't the first tranny form out there that I've heard do this. Tranny seems fine shifts all right just a whine while accelerating.

F250 5.4L have had a new fuel pump installed and new spark plugs (one blew out). When accelerating, or at a stop i get a kinda hesitation. It did it when I first bought the truck but put correct size tires on it and it went away. What it may be? I don't have a check engine light or anything and at cruise speed no problem--it's just when a slight load is put on the engine?

I have a 1999 F 250. When I accelerate my AC from the vents changes to the defrost. Other than that it works great and is ice cold. Why it's doing this.
