I have a 1999 f350 7.3 diesel. If I apply the brakes when I am not moving it is almost impossible to move the steering wheel. I have flushed power steering system. This problem has gotten worse over the corse of owning the truck for the last 10 years. Ball joints and u joints are good. Had to change power steering cooler a few years back, rusted out line, really got gradually from there.
View 9 RepliesAlright, I have a 2002 f350 7.3 4x4 ext cab xlt with 300k miles. Bought in may 2016 with 260k miles and towards November started running rough and felt like a loss of power. Had a no start but a new gray cps fixed that issue. Running fine. About a week later started it up and it had a rough idle, felt like not all cylinders/injectors were working. Was "knocking" and a loss of power. I was in the army at the time and stationed in Georgia, took it to a local diesel shop in Georgia and they confirmed my icp sensor was bad and injector #1 , #5 #7 were bad. Work was busy and money was scarce so I left it as it is and was saving up to buy the new parts. Then one day approx a week after the visit to the shop, I started the truck up and it ran fine. No misfire no knock no rough idle, drove fine for about a month.
In December, I was on vacation in florida to see my parents, drove the truck down, ran fine. While on vacation one day in a Walmart parking lot the truck didn't start up. Couldn't fix any issues then so towed the truck to my parents house. Did more troubleshoot, replaced fuel filter, cps, ipr valve, icp sensor, glow plugs, glow plug relay, ebpv pedestal was replaced with a ebpv delete pedestal. All parts bought oem and/or from riffraff diesel. Still would not start up. So then I bought a refurbished IDM from eBay, oem and then the truck finally started up one day but running rough again like it used to, then it wouldn't start again. So then, I replaced the PCM with a reflashed/refurbished one off eBay and boom truck started up, still running rough but now it starts up every time.
Now, took all eight injectors out and replaced all the o rings. Cleaned them up and put them back in, truck still running rough. Injectors didn't appear damaged nor the wiring harness so now I bought three reman injectors from riffraff. And replaced those three bad injectors. One of them is not spitting oil out the oil spout on the injector.
My dad has worked on freightliner semi trucks for years and is fairly knowledgeable when it comes to diesels. However he did something very amateurish the other day. So two injectors were installed while we were still waiting on the third in the mail. He wanted to see how the engine reacts when that one bad injector was not in play, but instead of unplugging the injector under the valve cover, he cut the wire outside the valve cover to the injector. He stated it's not a big deal and he can solder the wires back together. But once he cut the wire, the truck sounded a lot stronger, still rough idle but definitely stronger. Before, you would be pedal to the floor and the truck barely moves forward but now the truck will lunge forward. A big difference in power.
Now today, third injector came, swapped them out and fired up truck. We didn't solder the wire yet just quick connect, same you would use to connect wires for a car stereo. The new injector was not spitting oil out the oil spout. Even at high rev and truck warmed up. Truck still runs better with that one injector unplugged.
Tomorrow we will troubleshoot if somehow there's wires that grounding out or burnt out somewhere but as of right now everything seems to be in order, the uvch are tight, and no signs of anything burnt.
Triple checked everything, still getting fuel pressure, still getting oil pressure what gives? I also replaced the MAP sensor. Fuel pump is fine, fuel gets to fuel bowl. The next thing I'm thinking is maybe the hpop but we have oil pressure so idk..
2003 F350 6.0L ... 171,000 miles ... 5,100 since oil change 15W-30 at the shop ...
I was driving on the interstate (50 miles of driving) struggling to maintain 70-75 mph at 2,200RPMs. I would accelerate and RPMs would go up to 3,000 but no speed. Before I could pull off speed slowed to 50 before dying. Sat on the side of the road 30 minutes before I could get it started. Had to give it gas. No misfires just quietly started. Couldn't go over 30 mph. Towed it to my destination 135 miles.
Volts on 7Pin FICM read fine.
Checked the fuel fulters. Air Filter. Tank for debris. Nothing.
My coolant reservoir was lose and I noticed a lot of coolant in the driverside front wheel well and down the left side of the undertruck. Reattached after checking FICM. Hope that was all it was cause I couldn't find any leaks.
I had Planned to have the oil changed before the return trip before this all happened. New to Diesel engines but I like a challenge. Where do I go next?
Truck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.
Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.
If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal
If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.
Last night, I left it running while unloading a trailer and come back to notice it was idling abnormal. I jumped in it and tried to move it and there was a noticeable loss of power. I unhooked the trailer and tried to get it home. I only made it 1/2 mile down the road when it started spitting and sputtering (surging ever now and then) to a level that it died completely. I was able to start it back and get it out of the road but had to be pulled into a drive. It got to a point it wouldn't start back at all.
Today it started up however still had a rough idle and really has no power to speak of. The more I messed with it the less power it seem to have.
I have searched the forums and tried these things:
1) Checked the oil and noticed it was on the low end of the operating range. I put some in it to put it back to normal.
2) Disconnected the ICP
3) Changed the crankshaft position sensor
4) I dumped the fuel bowl after it completely died (in case it had any water in the fuel bowl).
The fuel filter was just changed 2 weeks ago. The fuel pump seems to be operating correctly (or it at least refilled the bowl) and started again with a very rough idle.
It doesn't have a engine light on nor do I have anything to read any codes it may be showing.
2005 250 5-speed total oil pressure loss ... At 110k mechanic diagnosed failing phasers from noise, rough idle, loss of power under 1k rpm. (Crew cab long box xl bought new for $25k)(first 100k were from carpenters (hard miles) so this truck is barebones and usefulness is much higher than cash value). Truck has 146k
All symptoms typically disappear over 1k rpm so I have limited idle time and manipulated engine speed to try and maintain 1000-1200 and all has been well for past 36k miles. Today noise (valve clatter?) persisted at all rpm and during a scramble to get off the highway all oil pressure was lost (I'm aware that pressure gauge on dash is not 100% reliable). After total pressure loss I cut engine and called tow truck. Out of curiosity, I actuated ignition and motor cranked maybe two rotations, and then appeared seized. After about 45 min waiting for tow I went back to disengage 4wd and take my rifles and skis out of truck. At this time I actuated ignition again and engine fired and ran as it had for past 36k miles. I drove about one mile constantly watching oil pressure gauge, then noise returned followed by instant drop from normal to 0 pressure (dash gauge) I immediately shut of engine.
I am a mechanical engineer, but not a mechanic. I am familiar with the cam phaser system and I understand that their operation is directly related to oil pressure. Today's temp was under 0'F. I have a very skilled mechanic who works for around 30-40% of cost of licensed shop and I know his skills to be on par.
Here is this wonderful 5.4 's issue now, sometimes it will idle rough, sometimes it wont. sometimes it feels like it wants to stall, other times not. if im driving about 30mph up a hill around 1700 rpm, the engine feels like a bucking horse, it will kinda want to produce the power, but cant seem to find it till the trans drops to a lower gear. With this engine power loss is unacceptable because it came out of the factory with no power, i cant afford to loose more.
there is no check engine light. its been doing this on and off for a week. i dont drive it much, may 15 miles a day. i thought maybe it was bad gas , i had it sitting for a month, but since then ran almost 2 tanks of gas through it. Seems to act the worst when driving it, then letting it idle for 5 mins, then drive it again, that's when its very noticeable. no smoke from exhaust, no mixing of oil and anti freeze, plugs are a year old, filter is new.
I blew a power steering cooler line yesterday and lost a bit of fluid. Removed and replaced the line, consequently losing most of the fluid in the system (during line replacement). Re-filled the system and now i have great power steering when driving but none at idle. If I bring my RPMs up about 150-200. I get it back in full force. Could my PS pump be on the way out or might this just be air in the system?
View 3 RepliesMy 02 F350 steering lost all resistance. I can almost spin the steering wheel to each stop. What would cause that? Recent front brake rotor/caliper/pad replacement is the only thing the truck has had done since I've owned it. (2 months now). It's way too loose to be safe.
View 11 RepliesI've done all the fluid but the power steering and the coolant. I'd like to change out the power steering fluid in my 08' F350. What fluid do I need ?
View 2 RepliesSo I have a 1999 F350 diesel and the fuse panel under the steering wheel is acting up. I was driving my truck home the other night and I lost power and my truck shut off. I have had a problem in the past with the #30- 30 amp fuse ( controls the PCM and glow plugs from my understanding) that is under the steering wheel, I replaced the fuse and everything started working normally again.
Until the other night when my truck shut off, so I replaced the fuse the truck drove again for 20 feet died again, I was able to hold the #30 fuse and allow my truck to start up again but would eventually killed the PCM and shut off again and would not start up due to what I believe the fuse location shorting it out and killing the power to the PCM preventing me from starting it up again. I had my truck towed home and charged the battery and it started up fine the next morning. If I push on the #30 fuse my truck the shorts out and kills the power, I do not know if this is normal?
The fuse is sitting loose in the fuse holder is there anyway making it fit tighter to prevent it from being so loose? I have read every other post online about the problems and tried everything they have recommended but still can not figure out what was wrong with my truck. I disconnected the fuel filter heater, and also the wastegate solenoid to see if that would prevent the truck from shorting out if I pushed the fuse it did not work.
What the problem could be causing the #30 - 30 amp fuse to be shorting out preventing everything from working? Or how to test the fuse panel and all the relays?
Bought a 08 F350 with the 6.4 Liter, with 80k mikes on it. Was traveling up an incline. Both Turbo's were engaged, when suddenly I lost boost, and PSI dropped all the way down. They barely create any pressure now. Checked intake, also checked boots too inter cooler. All seem fine. After driving it for about five minutes at low PSI, a check engine light came on. It was a sudden loss of power.

View 7 RepliesYesterday while traveling about 30mph and starting into a slight left turn the steering wheel locked, when the brake pedal was applied it was rock hard and would not engage braking resulting in a single vehicle crash, no injuries. 8300 miles...
How would I make Ford aware of this incident and get them involved? Is it likely that such events may have been logged somehow in the computer? The truck is at our collision repair shop waiting for an insurance adjuster to inspect.
I recently graduated from a 2010 f150 XLT with F250 tow pkg to a 2015 F350 and am not liking the steering. I have owned the F350 for about 2 months and I have about 2500 miles on it. The more I drive it the more I hate the steering. The steering just seems loose and "squirrely" to me. I even took it to the dealership at a 1000 miles saying something is wrong and they said everything checks out. They, of course told me, it's because I'm used to the steering in my F150. I even told them to check the alignment because it didn't seem right.
I don't know if it's in my mind, but I keep feeling/hearing like something is loose on the front end, especially when I brake on road bumps. I thought maybe it was the ABS kicking in, but I don't think that it. I cannot pinpoint the noise and it's hard to replicate it, so it'll be difficult to get that across to the dealer. Any problems with the steering?
New too my Ford, but anyway it's -10 Celsius. My trucks been idling for a few hours and probably will all day because of my job. Usually idles about 600rpm normally. So today the oil temp was about 80degrees Celsius. Then the truck idled up too about 1000rpm for a while. If I touch the gas it goes back to normal idle speed but then starts idling up again after 30 sec. What temp does the truck want too keep it at?
View 3 RepliesI recently purchased this 2003 F350 DRW with the 7.3L, automatic trans. Truck has 140k on it. Three times now while the truck has been idling, the engine just died. The first time was a couple of weeks ago when I was pulling out of the driveway. Then again yesterday twice, once while just sitting at a stop sign. Each time it has started right up and ran fine.What is going on here?
View 1 RepliesI have a 2002 F350 with a V10, this just started happening where at times the truck will turn over but won't run... after a few times of trying to start it I pull the key out let it sit for 5 seconds then put the key back in and runs perfect..... now at the gas station the other day it started but ran like it was on 4 cylinders... I turned it off and restarted it and runs perfect. Heading to Kansas next week to pick up my boat and don't need problems....
View 4 RepliesSo, I'm tired of this crap power steering. Since I just blew up my lpop on my 6 blow, apparently a thing with manual trans, replaced and she runs fine, I decided it is time to fix the screwed up worthless sloppy steering, and almost lack of any power steering at stop or slow drive. Picked up a rebuilt pump., and took out my old box with 220k.
I almost bought a cardone box, but frankly my input shaft had less play than 2 I ordered in. The only problem with my box is it has a tiny amount of play on the sectorshaft which translates to a lot of slop.
I've been looking into hydraulic ram assist steering, as I run 6" lift with 37s on a crew cab long bed. The thing has sucked at life since I bought it with wider 35s a few years back.
Is hydraulic assist worth it and if I go drop 500 on a redhead box, between this and the ram, am i going to be looking at decent steering on road in the future? I have no plans to offroad this boat anchor of a truck. I have a nice fun light 2 door turbo montero for that.
Do I do it, or just stick with a rebuilt box and pump?
