Ford Super Duty (1999-2016) :: 2006 F250 - Hard Shuddering When Braking
Oct 5, 2016
When braking the truck shakes terribly, enough to toss a drink out of the cup holder almost. Sometimes there is a slight feeling in the peddle but not always. The shudder feels like it is timed with each revolution of the wheels.
It developed from a perfectly stopping truck over the course of maybe a month. I don't drive the truck that much either.
Things I have checked:
1, all u-joints, they all look and feel good, no play or slop in them
2, air pressure in all tires, even rotated them, no effect
3, brakes-front and back all looked good but I went ahead and replaced front pads and rotors, cleaned caliper pins, zero effect.
4, shudder exists whether in gear and slowing or in neutral, 2wd and 4wd
What the heck else is there to check? My first thought was, front brakes/warped rotors, but after pulling them apart there was so much life left on the rotors and pads and replacing all that with new did nothing! Could bad back brakes cause this much of a shudder? They look fine as well.

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...

My manual hubs on my 2006 f250 have become very hard to rotate so I would like to replace them. I saw that bronco graveyard has Warn hubs for a Dana 60 front axle. Is this what I need? My door sticker with the axle code is illegible, and I want to make sure I get the right hubs.

06 250 5.4 40k on it, usually when cold and accelerating engine will misfire and stutter and then continue accelerating. The wrench light will flash sometimes but it wont store a code. This used to be vague in occurrence but has now started to be more a common occurrence even when up to normal operating temps.It seems only to misfire /stutter on hard acceleration or towing/hauling heavy loads. The only answer I got from a mech would be to do a computer reflash, not sure why /how this would fix whats going on.

During the winter, the truck would always start very hard. When it was trying to start it would pump out some white smoke. Now during the summer the truck will still start hard. At one point during the winter we were getting glow plug codes, now these have gone away that its warm. We did replace the glow plug control module, but that did not solve the hard start during the winter. We figured that there was a bad glow plug which is sorting out the rest. So we then figured the hard start issue would go away with the warmer weather but it has not.

While in Tow/Haul with my 5th wheel when slowing down probably at 5 or 10 mph the last downshift is very hard and the brake pedal gets real soft until full stop. Afterwards the brake pedal is firm. Tow/Haul without the trailer is fine. It's an '06 F250 Supercrew 4x4.

.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.

So yesterday I drove across town and back to pick up a piece of lawn equipment. About a 30 min hwy drive each way. On the way there I was in stop and go traffic for about 15mins and noticed toward the end the truck would pull hard to the right when stopping hard and sudden. I figure it was my steering. Been having issues with horrible steering since my last alignment and adjusting the caster. Truck wanders, steering feels loose, will not fully recenter, and feels like it binds then releases toward center position. That's a different issue, I assume. I stop on the way to get some cash and everything is normal. Pick up the equipment and drive back. When coming to a stop the truck will pull towards the right and when I suddenly stop it now pulls to the left.
I get home and get out and smell something burning and hot. Grabbed my IR thermometer and hit both front wheels. Passenger is 150f brake rotor is 175f, drive is 280f brake rotor is 580f. So im assuming my caliper seized up or started to stick. I plan to jack up the front and look at the hubs and calipers. Any other test I can do to narrow down the culprit. I am thinking the hoses may be collapsing especially since I had to disconnect and flip them during the lift. Just weird that the hard pull would switch sides if only the drivers was sticking. Could my bad steering and brake issue be related? I have also noticed my braking power has dropped recently. Brake fluid looks good but power steering smells like brake fluid and is orange.
Pulled the tire when I got home today. A little resistance when spinning by hand, more than there should be. Pulled the caliper and greased the slides. Found out my hub is bad so those are on the short list now. Reassembled and had my wife hit the brakes while I spun the tire. Progressively got harder and harder to spin. Was looking at the brake hoses, how much should they move and ''shrink'' when the brakes are applied? Also if I hit the brakes repeatedly while rolling down my drive way the pedal gets harder and the truck doesn't want to stop and the pedal will slowly push all the way to the floor. Now I am just lost at what is causing my braking issue.

I have an 05 F250 Super Duty 6.0 V8 Turbo Diesel. This is my first diesel so don't know my way around it too much yet. I just don't know what could cause this problem. It sounds like a faulty sensor to me. But no engine light has come on. My oil pressure drops down to in the red zone when I brake while driving, then once I return to driving again it returns to the normal pressure. It's almost as if it has something to do with the tilt of the vehicle.

2014 F450. Front end and steering wheel shake violently when braking while towing a 20,000 pound trailer down a long and steep highway grade. It does not happen when towing my 12,000 pound trailer down the same highway. Could I be setting off the ABS braking system?

I have an 03 F350 4x4 dually. Was pulling hard left at low speed when braking (front). Replaced pads, calipers, rotors, hoses and tires. Still the same problem. You can feel the abs activate right before it almost locks up the left front brake (basically will pull the steering wheel out of my hand). BTW the abs light does not come on.

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.

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.

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?

My '01 f250 7.3 has gotten hard to start. It seems to maybe be due to cooler weather, but not always. I have been told that there is some sort of valve in the fuel tank that could possibly cause this when the fuel gets around a 1/4 tank or so. But, it's doing it at any fuel level. But it doesn't do it all the time. I do notice it more in cooler weather. Anyway, when I try to crank it, I'll let the "wait to start" light go off and then wait a bit more. I'll turn it over and it almost as if the batteries are weak.
I'll stop and give it a few seconds and turn it again and it will normally start. But sometimes I'll do this 5 or 6 times and it will finally fire. But the more I have to try, it's like fuel builds in the cylinders and it smoke like a coal train for a minute or so. Almost like gas motor that has been flooded. But the smoke burns off and it runs like a top. I was thinking the batteries may be weak , but sometimes the starter will spin the motor with no trouble at all. I'm at a loss. Is it possible for fuel to drain from the system causing it to have to reprime itself? Here lately the smoking has me concerned even though it clears up.

I own a 2011 f-250 superduty, and have been having a problem with the steering, it goes from normal to lost of assist. Real hard to steer and dangerous. Then it will go away for a month, then start again. Some one on this site told me to flush the system which I did and it was fine for a month. A friend at a local ford dealer told me they had contamination in the system and I had to replace pump, reservoir, and flush system again....

I have a 1997 f-250 heavy duty with the 7.3 I have been having problems with very aggressive and hard shifting. While it is acting up the overdrive light on the shifter blinks. This problem goes away and it might be good for a month or so, But it always comes back. I have had it to a professional trans tech, He replaced a part on the side of the tranny. I thought it was fixed, But now it is acting up again.

I have a 1999 f250 sd with the 7.3. I'm not sure what is going on with my pickup. When I turn to the right i can turn with one finger, but when I turn left i have to put some muscle into it. Power steering fluid is full. I raised the front end and it turns both ways easy. My ball joints feel fine, there is no tire shake when i have it off the ground. My tie rods feel fine also, nice and tight. I was thinking about replacing the steering sector to see if thats the issue but wanted to get a second opinion first.

I have a 2002 ford f250 with the 7.3l diesel. I recently installed a ts performance chip. On my pcm. And after i first tried all the different stages I didn't like how my transmission was shifting hard. So I contacted the manufacturer and he told me they could reprogram the chip for smoother shifting. So I removed the pcm and removed the chip. But when I went to reinstall the pcm I bent one of the pins on the pcm some how.
So I took it back out and straightened the pin with pliers . i reinstalled it back in the truck. Only to find when I reattached the battery cable I have no power to anything ignition ,horn, lights,Cigarette lighter etc. So my question is if the pcm is bad, or not contacting properly due to the pin being messed up. would that have anything to do with the lights and horn and all that? I suspect its the gem bsm or Vsm. Whichever one my truck has. But really not sure because everything worked fine just 20 min b4.

On my 2008 f250 I can not turn the hubs without a set of pliers...does that mean I need new hubs....
What auto tranny do I have with the 5.4.. is it a six speed...

I recently purchased a 00 F250 psd 4x4. Other than doing all of the fixes it needs to make it ride better I have been questioning the trucks "get up and go" and the EXTREMELY sensitive skinny pedal. Truck seems to pull very hard and puts out some black smoke under hard throttle but nothing like the really tuned trucks I have seen. But the skinny is so sensitive its hard to drive under 40mph in 3rd and once it gets up to 55 or so its real sharp getting on and off the throttle. Trans shifts great, TC locks and unlocks, truck runs awesome IMO but just a bit harsh. Is there a way to find out if it was tuned prior to me buying it other than inspecting for a chip, or is this the way they are and I just have to get used to it more...?
