Ford 7.3L Power Stroke (1999-2003) :: Rumbling When Hit A Bump?
Aug 21, 2015
Today I was driving about 35 mph when I drove over a small patch of rough pavement and I started feeling and hearing a rumbling sound from the right side of my truck.
It felt like I was driving on a dirt road so thinking it may be my flex plate I put the truck in neutral and the rpms went to idle and the rumbling stayed consistent with the tire rotation. When I get to about 5mph it just clears up and drives fine until I hit another bump.
Is this my wheel bearing?

I have a 2000 F250 superduty crew cab short box. It has any occasional issue of either just shutting down (engine dies) which seems to happen if i hit an occasional bump. The other issue has happened a couple of times which is it will lose power and just go to a rough idle. I shut it off and restart it and it will run fine. I'm wondering if it is the throttle position sensor.

I have a 2000 F250 super cab and the doors rattle going over bumps. I've seen the weather stripping mod and intend to do this but my drivers side doors are touching at the top. Would this indicate that the busings are shot? With the doors open, when I lift on the outer edge there is no movement in the hinge area. The drives door and drivers side back door actually touch and rub at the top. Any pointers?

What would cause me to lose accelerator pedal function after hitting a bump? The engine remains on, the CEL comes on and after a few seconds or shifting into neutral and back into drive I regain the accelerator again and the CEL goes out
The truck shows no codes. It is if some connection makes/breaks intermittently when I hit a rough pavement. Also, she sometimes won't shift in reverse. Could it be related?

About 4-5 weeks ago my 2002 F-250 7.3 just died with no warning after coming off the highway and since then it hesitates/dies when hitting a bump or while applying pedal with the A/C on. The code that keeps popping up is the P0344 "CPS" and the code for back pressure sensor... I have replaced the CPS twice "making sure the 1st one was not bad", the back pressure sensor and the tube the goes the manifold, and fuel filter and still having problems... I didn't know if there could be a fuel pump issue or something else?

For probably years, I have had a bump, thump type noise when I start from a dead stop... say at a red light. I had it in my head, maybe there was that much slop in the drive train... as old truck is over 400,000 miles.
Yesterday, I rebuilt the driver's side axle, bearing,seals, new hub...the works.. I heard that noise again later... and my thoughts were, I did all that work and I'm going to find a lower/upper ball joint is bad, although I did look at them and thought they were fine during the rebuild.
Had my wife get in truck.... and swing wheel back & forth... so maybe I could see what was loose.. or making noise.
I was shocked... just something I never thought of looking at. The u-bolts holding the leaf springs were loose... the whole axle was shifting back and forth on the axle. I've never touched those bolts....

2003 f-350 6.0 4wd dual rear wheels
4 inch superlift suspension lift, dual shock steering Stabilizer
33 inch wheels.
4 inch turbo back exhaust
Other than that it's really bone stock
Here's what's going on. In 2wd, between 55mph and 62ish mph, once I hit a constant speed, a rumble beneath my feet emerges. If I either speed up or slow down, it immediately goes away.
Does the same thing in 4wd high.
I can eliminate front drive shaft and u joints seeing as they shouldn't be turning while in 2wd. I did notice that when I push up or side to side motion in the front drive shaft, there is a click and a bit of motion. Is that normal? Just a side thought.
When i take off there's a bit of vibration from the rear half of the truck, but I've isolated that to the center support bearing. With all this being said, none of these symptoms were around before I lifted it.

Truck ran good, but for the past month every once in awhile it would just stall quick, no rumbling, no smoke, like someone just turned off the ignition, if you turn the key it would immediately fire right back up. Well today it would not start back up. Pulled the IPR plug, no good. FICM replaced abt. a month ago. Checked with Scan Gauge, oil pressure abt. 925 while cranking dropped to abt. 780 after extended crank. And no codes. I do notice when turning key on I hear less clicking/noises going on. All dash lights come on and turn off as usual. Tach doesn't move.

Last November I forgot to plug my truck in and it got down to 0, my girlfriend tried unsuccessfully to jump start it. When I got home I jumped it and got it running. I took it down to a heated shop to troubleshoot the glow plug circuit. I discovered it was not getting 12v to the glow plug relay. Also I started it and tried to back it up in the shop, when put in reverse it killed the engine, not lugged it down it was like you shut the switch off.
Also I discovered if you turn the lights on it kills the engine immediately. It will not crank with the lights on either. So far I have replaced the computer,ignition switch,batteries, and cam positioning sensor. Now comes the weird part!! I decided to get it running and pull the bulbs out of the back up lights I pulled the drivers bulb first then the passengers side bulb. When I pulled the passengers side bulb it killed the engine.
It is not my daily driver so it still sits in my shop. I have a hunch it's a ground issue but I've checked and cleaned up all the grounds I can find and it still has the problem.

Brakes seem fine even when the light comes on so I'm guessing its more a sensor issue but which sensor? From researching others posts about ABS lights, seems the sensor on top of the rear differential is a common culprit, but I'm not having an speedometer issues, which also seems to be related to that sensor. It used to be if the bump was big enough to kick the cruise control off, the ABS light popped on as well, but now it's only a moderate bump and it will come on. Shut the rig off, re-start and the ABS light clears, until the next bump that is.

My 6.0 powerstroke keeps shutting off when I hit a bump. It's like everything died and reset and I loose all memory to stereo and everything. When I got to work and popped the hood I tapped on the battery cover by the pcm and it shut off again.

I have searched and have found a few threads on various transmission shifting issues. However nothing really pertaining to 13+ trucks that is only happening under certain conditions. It seems earlier trucks with problems were experiencing it all the time, not intermittent.
Here's what I got.... This only happens when:
- temp is 20 degrees or colder
- Truck has been sitting and is cold
- Trans temp under 70-80 degrees
- Only happens on the 3 to 2 DOWNshift when cold
The first few downshifts from 3 to 2 have a slight clunk/bump to them...just enough to feel it. After the first few initial downshifts from 3 to 2, it will not do it then, shifts fine and smooth. After a minutes of driving it, it will not do it until the next time it meets the list of items above. If I skip this gear manually until it has warmed up, it will not do it when returning to it.
-All other gears both up and down shifting feel good just the 3 to 2 when it does happen.
Once the transmission is warm or the temp is warmer outside the problem is non-existent and transmission shifts great in all gears and is smooth as butter!

The first time it happened, I wasn't monitoring any PIDs as I didn't have my phone with me. Not really sure if I hit a bump or anything, it just stalled. I pulled it off to the side and put it in park and started cranking. Turned over rapidly but wouldn't start. I started freaking out thinking what am I going to do? Shut the truck completely off and waited a couple minutes and then turned the key and it started right up. Drove to my destination and didn't have another issue.
I'm only driving my truck on weekends as I have a company van and I can't park my truck at the condo I'm living at right now. So sometimes it's a few weeks between drives. This has been the story of my truck use since I nought it 3 years ago. In fact I know my turbo is sticking as the most boost it builds is 20-22 psi. I probably have a sticking injector too, as it smokes unburnt fuel until warm.
So the last few weeks when driving, I've noticed that if I hit a big bump, occasionally it dies again. What I've discovered is that it won't start unless I shut the key off entirely. Meaning, if it stalls I put it in neutral as I coast, shut the key off as far as it will go and it will start up. If I just throw it in neutral and try to start, it won't.
Watching my Torque Pro display, I've noticed that it locks up (like normal when I shut the truck off w/o shutting the Torque app off). The display then has read lower voltages than normal for FMP, FLP, FVP (main, logic and vehicle? can't remember ). FMP is normally at 48.5v and the other 2 hover around 13.9v. The last time it stalled, I noticed 9.3v for FLP and FMP was 23.4. I'm not sure if this is what it shut off at or if I panicked and tried starting it w/o shutting the key off entirely. So please don't take those readings as gospel.
I scanned it for codes, but nothing popped up.

My 2006 f-250 just started blowing the #22 fuse when i go over a bump! Where the wire harness is for this. I've checked all the harnesses I could locate that looked like they could be rubbing on something.

So with the hurricane coming to my house I did the balljoints on my drivers side yesterday to prepare to evacuate today. Everything went smooth with no problems. Now fast forward to the drive to Orlando, I hit a bump going 65 and my front right side (ball joint replacement side) starts humming. I pull over and it stops, get out see nothing obviously wrong and start back on my way with no noise to speak of. It happened again and again I just slowed to almost a stop and it went away. Yesterday after the repair I took it on a trip through some crappy roads, the freeway, and all that to ensure she was safe with no problems. Maybe it is the bearing failing all of a sudden (it looked fine when I took it off). I have had a vibration at 55 consistently i think is the tires now that I replaced the ball joints (was waiting to have the tire shop check balance until after the repair) maybe that could be it?

I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?

I have a 2002 7.3L Screw 4x4. Will a 03/04 6.0L instrument cluster work in this truck? The 2 clusters appear identical. I put the 6.0 cluster in and the trans temp, and coolant temp gauge will not work. All the gauges sweep when it is powered on, but the coolant and trans temp lay flat, and the check gauge light is on. All other gauges and functions work. When I put my other cluster in, all gauges work fine. Is there a difference in the VSM, PCM, or the SCP communication?

I have a 03 F-350, 7.3L. There is a slow oil leak that only leaks after I've run the truck. In other words, it doesn't just sit and leak overnight. I'll park it after running, and the next morning I'll notice a small pool of oil, approximately 2" in diameter. The leak appears to be coming from the oil pan area. I degreased the entire oil pan area to get a better visual of where the leak is coming from. I can see oil trailing down the front of the oil pan and the rear of the oil pan. Does this sound like the gasket? Or, what else could it be? I'm praying its not as bad as I think and need to replace the gasket.

I have a 2003 F250 7.3L. I put new injectors in my truck four months ago and all of a sudden, I have 2 cylinders not working correctly, making the truck to run really badly. I sent the 2 injectors from the bad cylinders back for warranty and they replaced both of the injectors but nothing was wrong. I put them in and the truck still runs badly. I have a new fuel filter, new ICP, new CPS and glow plug relay. I cannot drive the truck, it smokes white at idle. I can unplug each injector at a time and cyclinder 5 does not change how the truck runs

I have a 2001 ford 7.3l powerstroke diesel. When I first noticed the problem I was towing a trailer going up a grade and got into the throttle almost to the floor and noticed a loss of power and the service engine soon light flashing extremely rapidly a few times and never came back on. I made it home, still lacking power but not running rough. I drove the truck to work the next day and the truck was running rougher and loosing power. It ran great through lower RPM's but seemed to trip as soon as you gave it over half throttle. eventually the truck wouldn't run right at all and lacked complete power. It idled rough as well. My mechanic threw the computer on it and it said injector pressure reading too high or too low.
I was told to replace the IPR on the HPOP and I did. (I also replaced the fuel filter and changed the oil). After replacing the IPR it ran great, had full power! then it began to slowly die like it did before until it sounded like it was running off 4 cylinders again. I pulled the ipr out, cleaned it and changed the oil again. It seemed to clear it up for an hour and ran great but then began ran rough again. I also replaced the CPS sensor. I feel like its not getting enough fuel or something, im just wondering if it could be the ICP or the lift pump. There is no check engine light at all. Its just got me stumped because cleaning the IPR clears everything up.... temporarily.
