I 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 RepliesI don't know what's going on maybe some body can shed a little light on this. If you hold the brake pedal down for a long period of time you can feel the pedal slowly go to the floor. So no problem I'll change the master cylinder bleed everything brand new fluid. Don't drive it much we let the sister in law drive it we'll I jump back into it the other day to go to Home Depot and once again I notice it still does it. Could the hydra brake booster be bleeding by or what's else could be causing this it's driving me insane. I really can't imagine the hydra booster causing a problem but it's new to me. I was thinking about bleeding the brakes again thinking there maybe there's air but I have run 2 bottles of brake fluid through how much more??
View 8 RepliesI have a 1992 Ford F-250 custom 2WD. My stepfather in law gave me rims from a 02 Ford F-250 for my truck. But I know the lug pattern is different so I will be wanting to put some adapter/spacers for those rims. But I need to know the offset of the rims I have now to make sure I'll still have a turning clearance if I was to get the adapters/spacers.
View 4 RepliesMy 92 f250 5.8l 5 speed, out of no where when I try to start it I get absolutely nothing, when I put the key in the on position and short the solenoid it starts up that's how I've been starting it? When I try to start it regularly it's almost as if trying to start it without pressing the clutch it literally does nothing.
View 1 RepliesI have a 2001 Ford F250 V10 with about 70,000 miles on it and now the gauge indicates low pressure when my warmed up truck idles around 1000 RPM.
I went off road the other day into some mud and since then I have had my oil pressure gauge reporting low at idle and normal when moving.
I was a quart and 1/2 low on oil which I filled and the next day I changed the oil. I then had taken it Ford shop who replaced the oil sensor and said all fixed. It wasn't and I took it back in ... now the mechanic indicated it is probably the crankshaft bearing based on his experience and I should replace the engine.
This seems drastic? Wouldnt' the next step to go check/replace the oil pump?
I have a few F-250's that have been having steering problems. and they all have the same symptoms.
When taking a long slow curve, the steering wheel will jump back like 6 inches, as if the pressure is going out. like say you had the vehicle turned to about 10 oclock, the wheel would go back and forth between 10 and 11. However, you do not loose much of your turning. It just has more pressure against your hand as if the power steering goes out.
You can also do it a standing stop. Only when you turn your wheel like say to 9, you can just use a finger to hold it there and it will bounce up and down? I have asked the local Dealership, and their answer was "there is something wrong with the power steering." couldn't get much more vague than that I guess.
I have looked for leaks, none. Checked struts, not bent. Checked tires, all brand new and balanced. Checked steering wheel mounts, all good to go... ???? Just lost...
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.
What is the proper tire pressure for these trucks (F250)?
Sidewall says max is 80 PSI.
Door jam says 71 PSI.
This is coming from a guy who has traditionally driven passenger cars and trucks. I've never even gotten CLOSE to advertised max PSI ratings. 71 seems awful close to max PSI.
Started truck it ran about 10 sec. then quit, low oil pressure came up on the dash will not start now.
View 2 RepliesI 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.
View 8 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?
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 have a 2001 F-250 XLT 4x4 with V10. Truck will not start. No fuel pressure. My Haynes manual does not show ignition or fuel delivery wiring. I have found the relay box behind the radio/dash. I need a wiring diagram and info on which relay is the fuel pump relay. Want to know so I can jump relay to see if fuel pump is okay.
Truck had sat for a few weeks being ran very little, so had to jump start yesterday. Ran for about 15 min, the shut off, re-started and ran for 30 min. Truck sat for about 1.5 hours then would not start. Charged battery overnight and it is 100%.
My uncles 1999 v10 started to leak from the high-pressure hose on the gearbox. Replaced the hose which lasted for a short time but is now leaking at the same spot. The hose swivels, is this normal, seems like a dumb design for a pressure hose. Also is there a certain trick to doing this hose? He also insists on using PS fluid instead of the ATF it calls for. Could this cause a problem with the seal?
Edit: Also the truck has been lifted on 35s since 16k miles and its now roughly at 170k. He tows with it as it is his work truck. But the truck is well taken care of.
2000 f250 V10 ...
Problem: More often than not when the key is turned to run (?), prior to engaging the starter, the fuel pump does not turn on for its 5 seconds. I have installed a fuel pressure tester gauge to watch the fuel line pressure. It was a little shaky to diagnose because if the line had pressure/fuel from the previous run it will start and run a short time and then die from lack of fuel. Unless the fuel pump activates when the key is turned to run, prior to full start, then there will be no fuel coming from the pump. No start. If you work the key to run a few times until the pump engages its good to go. The truck has never died while driving, once it gets that initial pump activation it runs good until the next start up cycle. When the pump does work it builds up to good "book" pressure and holds it at 39 when the engine is shut off.
We have put off changing the fuel pump for obvious reasons but can not see how it could be the problem since it has never quit once after we get it started. Are we wrong? We know the fuel shut off is on as it will run. We have changed the key lock tumblers, the ignition switch and the fuel pump relay. (behind the radio). Next up is to re-seat all the fuses and relays in the main fuse panel box under the hood. I just read that today on FTE. Is there a test we can do or some engine codes we need to look for? This problem is getting old fast.
2003 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 RepliesWhile driving today, 2006 Ford F-250 5.4 L V8 138,000 miles , I experienced a problem. Started with the truck acting as if it was running rough, possibly missing. This was approx. 10 Minutes after starting. Checked the dash, no warning indicators and all gauges were normal. Approx. 4 more miles, the oil pressure alarm signals and I see the oil gauge has dropped to zero. I pull over, turn off and check the oil. Oil is clean and at a normal level. I restart the truck and the oil pressure goes back to normal.
Rev the truck up while sitting there and after a few seconds i hear a knocking noise in the engine and oil pressure drops again. Call the tow truck, driver used to be a mechanic . He asks me to start it again and the same thing happens. If you start it and let it idle oil pressure seems to go up to normal with no engine noise. Finally get to the mechanic and he calls me later saying the oil pump and screen may need to be replaced or the engine may need to be replaced.
2010 F-250. the tire pressure warning light is on and the cruise is not working. Verified all TPMS sensors are working and sending signal with the reprogramming tool. using my scan tool, I got several U codes saying there is no communication with the instrument panel control module. I have cleared the codes, they did not return immediately and the problem persists.
View 2 RepliesI have a 2010 f250 6.4 About two months ago the truck just quite on me. I am a farmer in south jersey and have a decent background in diesel motors. First thing that came to mind was fuel. I assumed I was having a fuel issue (clogged filters, failed pump, etc.) truck only had 45,000 miles on it so I took it to my local dealership for what I assumed would be a warranty job. I dealer service all my trucks while under warranty. Long story short I was told it was a fuel contamination issue which scared the walls of the hpfp throwing metal pieces into the injectors, fouling them.
I would need all new injectors, fuel rails etc. as well as new filter housings, fuel tank cleaning, etc. I had receipts for every drop of fuel put in the vehicle and fought all the way to through the dealership to Ford who sent out a rep and who denied the warranty work. Fortunately my insurance company covered the ordeal and all repairs were completed. I got the truck back and 2 weeks later the truck died on me again. I called the dealership back who supposedly warranted the repairs but there first words were there is no way it is their problem, they would look at it but I have to consent that if they find it is contamination again I am responsible for the repairs which we all know just to diagnose they have to remove the cab etc.
I of course lost my mind and told them this is there issue and there is no way in hell I am that unlucky that I received 2 bad tanks of fuel from 2 different high volume highway side fuel stations in the same 2 months. it is obvious they missed something or there is another issue that was not addressed. They claim there is no way they missed something. I am at a standstill.
