Ford Super Duty (1999-2016) :: 2003 F350 - Vibration / Shaking When Brakes Applied
Aug 27, 2013
I have a '03 F350 that I can't seem to solve the brakes vibrating when applied. Replaced front rotors a couple weeks ago. I still have a vibration when I apply the brakes. What am I missing? I didn't replace the back rotors, but maybe I should have. On the passenger front, the inside pad was almost gone and the outside pad was in good shape. I greased the pins before I replaced the pads the last time, but the inside still wore much faster. I also blew out the rear brake line last week and spent Saturday bending a new line and replacing that so the brakes were bled when I had to replace that. I don't feel the pulsing in the pedal, but the truck shakes pretty good when I hit the brakes. What else should I be checking if the rotors are new and the pads are new and the pins have been lubed and the brakes have been bled?

I need fixing my 2003 f350 6.0 diesel, I have been working on this truck for a while and still am having problems, here was the original symptoms:
-Hard start or no start on a sunny day
-Rough idle for 10-15 minutes
-Rough shaking in the low RPMs (35 mph)[/COLOR]
-Slow response from the gas pedal
-boost would only get to 14
My dad and I then did many things to the truck in the shop, those things are:
-Air test and replacement of coupling going into oil branches (next to HPOP)
-Replaced EGR valve (no good)
-Replaced ICP sensor (leaking oil)
-Replaced ICP sensor and IPR valve piggtails (due to frayed wires)
-Cleaned Turbo
-Cut MAP sensor hose and reattached it (spliced on the end)
-New battery
-Performed a bubble test and found two bad injectors on passenger side (injectors #5 and #7)
-Cleaned and lubed tops of injectors
-Replaced O rings and copper crush washers on all injectors
-Replaced nipple cup O rings (tight)
-Blew out injector cups
-Bubble tested after injectors put back in (no more bubbles)
-New FICM, EGR cooler and oil cooler were already installed
-Ohm'd main engine wiring harness (good to go)
-Taped up frayed wires on fan clutch connection
-Increased wire gauge on the positive jumper between both batteries
-Sanded each ground on the batteries and engine, cleaned battery clamps, lithium greased connection points.
-Checked fuel for air (no air)
-Checked fuel psi (85 psi, plenty)
-Oil changed
After doing all of this (diagnosing as we fixed each thing) we now fixed many things including the hard/no start problem. Now, for the first three to five minutes:
-It starts right up
-Runs perfectly, no shake and instant response from the gas pedal and turbo
-Boost goes to 28
-ICP is 800-950 on idle
-IPR is 25-26.9% closed
After five minutes however:
-Starts to shake
-IPR % starts to raise
-Received no response from gas pedal (absolutely no power)
This truck has been torn apart like 8 times and I have to do it on my spare time.

Buddy has a problem on his '03 F-450 cab and chassis. When he turns on a turn signal, everything is OK...but it goes out when he applies the brakes. Also, the brake failure light is lit up on the dash, despite the brakes being fine. These problems happened at the same time. I'm think a ground, but not sure where to look.

I have a pedal pulsation, steering wheel shimmy, and pull to the right when the brakes are applied in my truck. It is a 2009 F250 4x4 gas V8. I just replaced the pads, rotors, and calipers on the front and that's when the problem started. It definitely gets worse with speed too. I replaced the calipers because the right one had seized up and the left one looked to be on the way. There are no odd noises and the wheel bearing doesn't feel like there is any play in it. What this could be?

I recently took delivery of a new 2012 F250. It was a cab chassis, we had a utility bed and lift gate installed from the upfitter along with heavy rear springs. From day one the truck would pull left when the brakes were applied. The brake pedal also feels mushy, not firm. It will firm up when I pump it. I could also smell burning around the left front of the truck when I would get out of the cab. Hot brake smell. Took it to the dealer with only 400 miles on it and they replaced the front pads and turned the rotors, and gave it back. In relatively few miles the problem was right back again.
Took it back to the same dealer last week with 1200 miles on it now. This time they say they replaced the rotors. I went and picked it up it this morning. Within 5 miles drive of the dealership I can tell the brakes are still bad. Now, it will kind of do a "head fake" when the brakes are applied, pulling slightly left or right, before deciding which way it wants to pull. It will pull right or left now during firm braking. And the brakes were stinking by the time I had it back to them. I turned around and took it right back to them again. Brand new F250?

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.

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!!!!!

Having a somewhat scary problem.....my truck is already a rough ride due to the fabtech lift and the 37's and you get a lot of feedback through the steering wheel. Its a rough ride down the highway but where it gets scary is at lower than highway speeds like 35-45 range. I can hit a bump and it will send the trucl into this insane cavitation that will literally shale the fillings out of your teeth. I cannot tell if it is in the drive wheels or the front wheels. The best way I can describe it is that its like trying to push a buggy in wal mart with a bad caster wheel on it. It feels like you are about to have a wheel fall off or that its broken off a tie rod or something. Then you simply slow down to a stop and you can drive right on like nothing was wrong. The vibration or shaking does not slow down with the speed. I cannot find anything obvious broken or damaged but this thing is getting dangerous to drive.
05 F350 DRW Fabtech 6 inch lift and 37's. 114k miles.

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.

Got a problem with my F350 diesel truck's braking system. I pull a 5th wheel and last trip almost burned my breaks up coming down long hill due to having no breaks on the 5th wheel. Had a problem early on with the lack of trailer brakes and module was replaced under warranty. Bought a new module this time and it did not fix the problem. Have braking power when I use the module brakes (Hand) but not when I hit the foot brakes. Have checked the system with a meter and have good voltage with hand break but not with foot brakes. Have a good meter (voltage) read with hand breaks and faint read with foot brakes applied. Also have a faint pulsing read on test light with no brakes at all just key on.

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.

Problem started with the front end shaking a little bit when braking like the rotors needed turning. Then the brakes began to intermittently hum when stopping. Then my ABS light came on. Put the truck up on the stands and disassembled the brakes on both sides. The ABS sensor was chewed up on the driver side. The less than year old hub felt sloppy so I changed it. Put everything back together.
New hub came with new ABS sensor. Went for a test drive ABS light is gone and I no longer shake or experience the hum when applying the brakes. However now when I go to stop right before I come to a complete stop the driver side (new hub/spindle side) I hear what sounds like the grade school class clown making a fart sound with his mouth, and the truck pulls to the driver side. Is the ABS system malfunctioning or is this a caliper issue? Calipers look like they are OEM.

On my 2007 f350 when I hit my brakes it pulsates... So I put new rotors and brakes up front.. The pins are good and the calibers are good... put it all back together and still the same thing... the slower you go the slower the pulsating gets... And I can actually feel the pedal move in and out when it does it... I'm lost....

I 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.

I'm having trouble finding the source of a vibration in the front end if my 1999 f350 super duty 4x4. The vibration is felt all the time but worse when under 40mph, while braking, and especially when turning.
I have replaced the rotors and brakes, tie rods and Drag links since the issue started but no change. In the vibration. What should I check next?

My '05 F350 PSD has developed a pretty bad vibration most noticeable above 40mph but only under acceleration. As soon as i hit speed and let off the gas its gone but if i accelerate again to pick up the speed i lost its back. Haven't looked into it too much yet as i was busy all weekend and drove the Expy but I did get down there and don't have an obviously bad u-joint or carrier bearing. I'm also gonna see if i popped off a driveline weight or something.

I feel a vibration and hear a rattle/grinding noise intermittently in the front driver or passenger floorboard only when the truck is cornering AND starting uphill or downhill. The vibration lasts a second or two and seems to be directly related to throttle/rpm acceleration while cornering and not something just loose and clunking around.
Dealer could not reproduce but it just happened again yesterday a couple of times in city traffic after dealer inspected and greased front end zirks.
What should I be looking for and how would you go about getting this resolved? It started happening in the last couple of months and never made a sound prior. Truck is in year 4 of 6 year warranty so I want to tackle now, but I need better understanding of problem.

I have a 2007 F350 XLT, Super Cab, chassis cab, V-10, 4x4. I ordered it new, it now has 97,000 miles. It is equipped with a 9' aluminum flatbed. I tow it behind my motorhome and also carry a truck camper (not when towing it!).
I don't think the front brakes are working 100%. I have 2 sets of wheels and tires (19.5s for hauling the camper). Every time I change over, I check the brake pads for wear. Over the first 80,000 miles there was very little wear on the rear pads. In 2014 I had almost a complete brake failure while traveling. I took it to a Ford dealer, and they determined the brake booster was bad. They replaced the booster and flushed the brake system. I didn't think the brakes felt right afterward, but I carried on. By 95,000 miles, the rear brakes were worn out. I feel like the rear brakes are doing most of the stopping now, thus wearing out much faster than they were.
I just ordered a set of service manuals for the truck (9.5 years late on that!) hoping to figure out something. I like the truck, it meets my needs, and I hope to keep it quite a while longer. I took it in to the local dealer to replace a leaking rear pinion seal. They found and replaced the worn pads. I trust them to the extent that the pads were worn, as I had already noticed an acceleration in wear. Local dealer that replaced the pads has no idea what could be up. They did clean and lube the front calipers at the same time, but I noticed no difference in brake feel. Stopping power is definitely worse than before the brake failure/ booster replacement.
What might cause this? The only things that come to my mind is a problem with the proportioning valve or maybe the master cylinder. I don't know much about the details of the ABS system. Is there anyway that might be causing the issue? I would rather not just start throwing parts at the problem...

2000 F350. 4x4, V10. 153,xxx miles. Here's the story. Whenever I hit a little bump in the road, I get a vibration directly under my feet and in the gas pedal, NOT in the steering. It will go away pretty quick or when I hit another bump. It only happens when the front driveshaft is not spinning. Hubs locked in in 2WD, it doesn't vibrate. Hubs unlocked and in 4x4 High it doesn't vibrate.

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.
