I've replaced the brakes that weren't in that bad of shape anyways and even replaced one of the rotors as it was under federal regulations. I've even put the brake squeak goop on the back of the pads and it keeps squeaking and squeaking and it's driving me insane. Am i missing something here? I don't here any other super duty's squeaking on the road.
View 1 RepliesSo a few week back I noticed my brakes were getting soft. Soft meaning that when braking for any distance, I would hear a kind of "pressure release, squeaking" sound coming from the pedal, and the pedal would sometimes go to the floor and the ABS would kick in. Let me tell ya, its a pretty crappy feeling when your brakes aren't doing what their supposed to! So, I replaced the pads all the way around, replaced the master cylinder (bench primed). I took it out for a drive, and it did the same thing. So thinking maybe the fluid is bad, I flushed new fluid through the lines. Took it for a drive, and it felt good right away, the pedal firmed up a bit, and then it did did it again.
Just so I give as much info as possible, the rotors are looking pretty rough and going to be replaced soon.
So, my question[s] are; What is the next step in identifying the problem? Is there a chance the new master cylinder is bad? Could worn rotors cause the caliper to max out and not apply enough pressure? Even though the calipers seemed fine while replacing the pads, could one or more be bad? If so, how do I know?
Can get up to speed about 55-60 in my 2003 f250 6.0 4x4 truck and hit the brakes hard and the pedal gets hard almost like you cut the truck off and the truck doesn't stop well I can let off the pedal and hit it again hard and it works like it should. Also when it does this the power steering doesn't work. I was on an exit ramp and almost wrecked when I exited off the interstate I hit the brake pretty hard and couldn't steer I let off the brakes then hit them again and it worked fine and so did my steering. It would seem that the two are connected somehow. What's wrong?
View 2 RepliesI have a 2000 f250 superduty gas v10 6.8L . I bought this truck about 4 months ago. Now when I take off from a complete stop the truck shakes up until second gear, shifts fine all the way up until the last gear it looses power "loosing power" i mean i can put my foot into the pedal and it takes forever to climb speed meanwhile the RPM'S never skyrocket like it the transmission was slipping if anything a couple times the RPM's dropped are stayed the same then as i take my foot off of the pedal once i have my desired speed sometimes not always the truck will give me a little jerk Also Just the other day I was driving on the highway and decide to put her on cruise control at about 70mph, I set the cruise control and the RPM gauge was just over 2,000 and the tach was fluctuating up and down about 1/16 of an inch. I been reading alot of forums and what I got out of them is it maybe pointing me to a misfire maybe the coil packs? Plugs?It's not something major like a transmission rebuilt.
View 6 RepliesNeed to know if the 5.4 and 6.8 use the same bell housing pattern?
View 5 RepliesSo, don't know if this is normal or not, but after lifting the rig, I'm experiencing a whole lot of these types of sounds from the leafs or the springs or whatever, whenever I start, stop, or turn. Is there an easy way to silence the noise? I've tried all sorts of lubricants on the leafs and springs, but I only get (at best) a week of muted noises. While it's only an inconvenience, it sure would be nice to have the rig be quiet again.
View 6 RepliesI posted a reply her a couple of weeks ago on how I fixed my '03 SD's squeaky doors. I went to AutoZone and bought 32 feet of 5/8 inch self-adhesive rubber (not foam) weatherstripping and mounted it around the outside edges of both doors, starting at the top. Presto - squeaks are gone, there are no more drafts and road noise is reduced a little. (I may remove the stripping I put on the side edges of the doors because I think the culprit is actually the rigid polyethylene bumper strip they've mounted on the upper door jam).
View 2 Replies03 F250. 5.4 2v ... I purchased it a month ago.
Squeak under the hood. It appeared to squeak in relation to the movement of the tensioner......simple right? Replaced Tensioner and Belt..... Still squeaking.
AC not working at all. Compressor never kicking on.....replaced compressor, accumulator, and orifice tube. AC works now!.....squeak still there....
Notice fan wobbling.....shut truck off.....fan clutch shot... replaced....STILL SQUEAKING!!
Obvious answer....sound still on that side of the engine....Idler pulley....I just replaced it and the dang truck is still squeaking!!!!!!!!!
All that's left is the harmonic balancer, alternator, and power steering pump.......What could it be?
I use a bottle hanging like an I.V. drip to flush the Brake Fluid in all my cars. I can pump all the old fluid out, as well as the air. My Superduty 7.3 has a good solid brake pedal after the flush. It seems to me the rear brakes handle 60% of the stopping load. Its been like this for so long I'm not sure if it's ever been different. i then go to a gravel or wet road and test the rear abs, and it seems o work, but definitely has a squirrely feel. I did some strong pavement stops with speed, and it stops, no skidding. Is that the way it should be?

View 7 RepliesSo to start at the beginning.... Traveled across Canada East to West towing 11000lb travel trailer, no problem. Have used 4x4 in a few campsites to pull out of a pitch without spinning the wheels and causing damage to the site when it has been really wet. All good.
Got to Banff in December and the town was an Ice rink, engaged 4x4 and all good. Crossed the Rockies and the 4x4 starts making grinding noises. Up and down some mountains and squeaking, grinding noise then clunking.
I have manual hubs, disengage and the noise all goes away. Engage 1 hub and no noise. Engage both hubs, noise back.
I bought some needle bearings and went to swap them. Got hubs apart and they look good. No scoring on the drive shafts. They are not dry, but as I have them open, repack them with grease anyway.
Do more research... Remove ABS sensor and repack main bearings with grease. (broke one sensor pulling it out, too cold plastic brittle oops). Still clunking noises.
The universal joints look good, doesn't appear to be any play in them. However, the axle seal (knuckle seal) (F81Z-3254-CB) does move around a lot in it's metal casing. It is tight on the shaft, but with the hub off, I can move it in and out, and move it side to side. If I had ESOF hubs I guess they would not be locking as I'm sure there would be no vacuum in there!
Question is then, would this seal be allowing the universal joint to wobble under load in 4x4 mode? Would this wobble be the cause of the rumble? As it is labelled as a seal and not a bearing, I wouldn't of thought this would have been a loaded point, and the weight would have been taken by the associated bearings and it could be run without this seal? But if it is not this, then I'm still looking for a clue as to what is making the rumble....
I have a 1999 f250 super duty, that was wrecked a few months ago. I have put the truck back together with the mechanic. The front drivers side was wrecked. The power steering fluid tank was cracked and had to be replaced. Also had problems with a box behind the drivers headlight? I did hard wire it together and it fixed the problems I was having the the speedometer and the transmission not shifting correctly. Everything is put back together now but I drove it today and the brakes locked down after driving it a few miles?
Had to push the truck hard to get it back to my house, a mile or so. If I let off the gas it would come to a quick stop. It is ALL four brakes locking up. If it sits for awhile they unlock but will lock up again after driving. The truck is lifted and the ABS light has come on. It was not on before but i am pretty sure the ABS is disabled on the truck. The wires are hanging down by each tire. This is how they truck was when i bought it. Not sure what is causing the brakes to lock up.
was going to do a brake job on my f250 light duty and the rotors won't come off. At first I thought they were rusted on but after looking at them it looks like the studs are attached to the rotor. Need to confirm this because the new rotors I got don't have the hub attached. Don't know if it's the wrong part or what?
View 9 RepliesI believe my brakes have a problem.
Lately, I can stomp on my brakes @ 50 mph and they won't trigger the abs or come close to skidding the tires. The peddle goes to the floor if I push hard enough and the truck doesn't seem to stop fast like it used to.
I'm wondering if there is an issue I should be focusing on, like swelling brake lines or some issue you may know of. I'll try bleeding the brakes this coming weekend, but i think its going to be a bad brake line or something.
i just bought a 99 F250 4WD with the 5.4 in it i put a brand new starter in it. When i turn the key to try to start it, it just cranks the motor once and stops. The starter isn't grinding or clicking, the motor clicks once and move the belt and pulley a little but that's it. What would cause this?
View 13 RepliesI have a 1992 F250 7.3 diesel 4x4 My brakes wont hold pressure I replaced master cylinder and calipers had the system pressure bled. I don't have any fluid lose and vacuum is good. Can the proportioning valve let fluid bypass, or the rear anti-lock braking system valve let fluid to bypass.
View 14 Replies2003 F250 V10 4x4. I have a rear brake sticking so I assume I have to replace the calipers. Which brand should I go with?
View 2 RepliesI 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?
View 1 RepliesThe front brakes on my '02 Super Duty squeal a little from time to time, but today have been squealing mildly while driving and get louder the further down I press the brake pedal until coming to a stop. All new brakes were installed less than one year ago.
View 11 RepliesHave an 06 F250. When I slow down to make a turn then accelerate it's like the drive shaft spins half a turn before it catches. Been doing it for awhile now. Now I'm get a clunk when I come to a complete stop. When you stop then truck settles there is a little clunk. Does this sound like the slip yoke problem?
View 1 RepliesI have a 2001 F250 V10. It idles around 1k and when stopped at stop lights or when put in reverse it stalls. I have replaced IAC, fuel filter, tranny filter, oil filter, plugs, coil boots, tranny fluid, oil, air filter, and PVC along with the PVC hose. I'm totally stumped. It doesn't stall if I do a rolling stop.
