Ford Super Duty (1999-2016) :: F350 Keeps Killing PCMs / Engine Hydro Locked
Sep 13, 2017
So I have a 99 F-350 XL, 6.8 2WD, got 268K on it and it's been a great truck, hasn't ever given problem until last June it killed out a PCM, hydrolocked the engine and sent a connecting rod out the oil pan, so I swapped the engine and replaced the PCM and everything has been great, everything that it's equipped with works great, it's a base model truck, used to be a uHaul box truck, and we got it with 239K on the clock.
Well fast forward from last June to this month and it killed out another PCM, so I got one out the JY with the same numbers and all on it, and it ran twice and killed that one too, and it's got me at wits end, since there's literally nothing that blows fuses or DOESN'T work, everything is perfect but it won't stop it's PCM habit. It's only killing them when it's switched on, to narrow things down.

The steering wheel is locked on my 99 F-350. I messed around with the stupid thing for quite a while this evening and it won't budge! I need it to haul hay tomorrow....

Well long story short, I had the the factory hubs in my 04 f-350 and I was driving down the road and it started making this horrible popping noise. So I pulled over and couldn't find anything and just curiosity locked in the hubs and all was fine. Made me think my hubs were bad, so I went and bought the warren premium hubs, installed them. Went for a drive and still the same noise is there when they are in free spin. But once they are locked in its fine. What this could be? Wheel bearings?

Yesterday 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.

My brother is having a issue with his 99 F350 diesel 7.3 automatic tranny pu. When in manual 1rst gear the engine stumbles and runs like crap. In drive or 2nd gear it runs fine. He's getting a code for a bad cam sensor. A new OEM and aftermarket sensor has been tried with no solution to the engine problem. What might be going on? Maybe a bad ECM.

2008 F350 hubs wont stay locked in when in auto position. everything stays locked while in manual and 4x4 works fine, but in auto the hubs wont stay locked while spinning. I was trying to find the problem when i noticed that one hub stays locked all the time and the other locks and unlocks as it should but it wont stay locked while spinning. My question is do I have two bad hubs or is their a leak that wont let the hub stay locked? Also on the hub that wont unlock is this a leak problem as well or a internal problem?

Ok so I got a good deal on a used F350. When I got it home I found the heater was stuck on defrost. I posted on here a few weeks ago with questions on what could be wrong. From that post I learned that my front passenger side hub is stuck locked in. I pulled the vacuum lines at every connection from the pump on and had good vacuum all of the way to the passenger side hub. I turned the axle shafts and found the drivers side is free the passenger side is locked.
I flipped the dash switch and heard the drivers side hub lock. Then I turned the axles again and found they were in fact both locked in. I flipped the switch back to 2H and the drivers side freed and the passenger side was still stuck locked in. So I pulled the passenger side hub off of the truck and found it was seized up. I put it back together and locked both hubs in manually until payday when I can pick up a new hub.
Yesterday we had a lot of ice! Where I park the pickup the front wheels drop into a low spot. I could not get backed out of my driveway with the front wheels in the hole and the rear wheels on ice, so I flipped the switch to 4x4 and tried again. It still could not pull out, the front wheels didn't seem to engage. Now I am thinking I have more troubles than just the one hub stuck locked in.
So, my questions now are, 1 if the passenger side hub is bad but both are locked in it should still go into 4x4 correct? 2, the 4x4 light on the dash lights up when I flip the switch. If I had a bad switch or fuse would I still get the same result (light on and drivers side hub clicking in)? Does this pickup have to move a few feet before it engages the 4x4 or should it click right in? And finally what is a short explination of how the 4x4 system works. The dash switch engages the solenoid on the firewall to switch vacuum down to the hubs but what else does it do? I assume it has some kind of switch or motor in the transfer case that engages the 4 wheel drive?

So recently i blew a seal in my steering gear box. I replaced the unit with a reman and per napa put in power steering fluid. I am pretty sure i was supposed to use atf (my dumb fault for not researching that) so now my question is whats the correct way to flush the system? Also what fluid should go back in the system? This is a non hydro boost setup. Setup is a 2002 f350 v10.

My 01 450 V-10 dump truck had intermittent clutch petal problem. Petal would not return all the way. Had to pull it up then it worked ok for a while. Now it only works occasionally. Could it be the disk is collapsing or the master or slave? Any good how to video for replacement?

2011 F-250 King Ranch, bought new, 59,995 miles. Dealer Serviced, always. ESP to 100K.
Took it in for an oil change, running perfect. Jan 4.
Service writer comes and gets me after 2 hours. "Engine locked up after they went to start it after oil change."
They are getting a remanufactured long block from Ford.
I am still in shock.....

I am looking at a 1997 F350 XLT 4x4 and it has a 5.8L engine. I have an 84 F250 with a 5.0L and it just doesn't have enough power when pulling a trailer. I am wondering if the 5.8L is enough for an F350 of if I should look for a 7.5L?

I have a 2000 F350 cab and chassis 4X4 with V10 and a 5 speed manual (actually it's a 4 speed with overdrive). My problem is the engine seems to have a miss in it. When I first start it in the morning it usually runs good for 5+ miles till it warms up then if I am not pulling a load I can hear what sounds like a miss but the truck accelerates fine. If I am pulling a load I can also feel a slight steady consistent shudder and I can tell the truck doesn't have the power it should and the gas mileage SUCKS worse than it use to.
I ran a bottle of Lucas deep clean through a tank of fuel and that seemed to work a little but I will still encounter the problem sometime during the day. When the miss seems to be gone I can hear a very slight pinging noise when I accelerate or pull a hill with and/or with out a load. The pinging noise I hear sounds like an engine with a distributor that is getting to much spark advance if you have ever experienced that before.
I purchased this truck used several years ago and I don't know what the PO did but the check engine light is not coming on and it doesn't throw a code. I put 10 new ford coil packs on it about a year ago so I really don't think it's a coil pack, but I could be wrong. To me it sounds like maybe it an injector problem????? I know there are several sensors on this engine and I am thinking maybe a crank position sensor is not working right but I honestly don't know???? Is there a way to test this sensor?

I have a 2013 f-350 with 58,000 miles. I'm a general contractor and drove my truck to a very nice home with decorative concrete. After I left the customers house they called my office to say I left oil stains on their driveway. I looked under the hood and noticed motor oil leaking on the front left side of the engine. I told the customer we will take care of the stain. I've never had a diesel motor leak this soon on me.
My mechanic told me to go to a Ford dealer so I did. The dealer told me that this is not covered under the warranty as it is a oil pump/brake vacuum. THE MOTOR IS LEAKING OIL. I told the dealer that the motor is leaking oil and I have a warranty that I signed up for. He told me that Ford considers this issue the same thing as an alternator.

I was recently involved in a fender bender. As I backed out of a parking space, I struck another vehicle. When I immediately attempted to pull back into the parking space to check things out, the engine in the F350 bus surged to the point that it crashed into one of the safety poles in the parking lot despite the fact that I had both feet on the brake pedal. The vehicle is 8 years old and has 25K miles (not used frequently) but never had this issue before. Could the crash have something to do with the vehicle's computer and the subsequent surge?

I 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?

My daughter came home a bit ago and told me the backup lights on my '02 F350 were on. Pretty odd because the keys were in my pocket at the time.
When I opened the door to the truck, I noticed a faint electrical smell and noticed the fan for the environmental controls was running as well.
I'm guessing the light issue is probably a sensor or something at the transmission but why would the blower be running as well?
Early last week I finally decided to try and figure out why my cruise control hadn't been working and discovered fuse F2.34 was blown. Replaced it and went through the test procedure described here: [URL] ....
No issues and the cruise is working again. I had to take it on a road trip for work the following day and didn't have any issues for almost 1,000 miles.
I drove it last night and didn't have the issue. I drove it again this morning to several places and everything was fine.
I've got a tuner with a code reader. Would something like the above problem register a code?
I've not stuck my head under the truck yet (it's cold and dark out.) What sensors I might need to check out? Is there a testing procedure available to ID the faulty component?
The battery is disconnected for the night, but I'd sure like to get this thing sorted before I hit the road for work again this week.

I literally just purchased a "new" 06 F350 and have had it just over a month. I bought it from a used car place in Salt Lake City and have put roughly 250 miles on it, it has 105k on it. While having 1 sled in the bed and towing a 1-place snowmobile trailer up a 8% grade my check engine light lit up. Little back story, there was a slight hiccup that I started to realize it had about a few days after purchasing it, would kind of buck a few times under normal acceleration around to 40-60 mph not every time just occasionally. Been meaning to take it to a friend to have it looked at, just been fairly busy.
Now when I was driving it back home (~8-10 miles, almost exclusively downhill) at stop light and accelerating from 0mph it would not prime the boost, I was getting almost no power until I hit 2000 rpm then all of a sudden things were fine turbo would engage I was able to drive normally. It hasn't moved in 2 days as I will not drive it until I know what is wrong with it. In doing a little research I read about turbo veins being stuck open, ignition problems, and a few other things that might pertain to what is going on with my truck. I have a buddy coming in the morning tomorrow to pull some codes with a scanner so I will have more information here shortly but I just wanted to get the conversation started on this.

My grandfathers 99 F350, started suddenly, do not know if it was while sitting or while driving. Its more of a stream than anything else. Coming from the rear, cannot see where, appears to be toward the vee of the engine, not inside the bellhousing. The firewall insulation is damp from coolant. Doesnt start until engine starts warming up.
Is there something commonly replaced back there? Didnt want to yank the intake in 20* weather for exploratory surgery. Is not the heater hoses. Idk if the EGRs are cooled on these, thats about my only idea other than freeze plug, coolant tests good down to -20ish, hasnt been below zero in weeks (prior to leak). Not familiar with any of the modular engines.
