Ford 7.3L Power Stroke (1999-2003) :: Rumbling When Hit A Bump?
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?
Ford 7.3L Power Stroke (1999-2003) :: Shutting Down When Hit Any Occasional Bump
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.

About two weeks ago my front tires started rubbing. I've been running the same size tires as long as I've owned this truck, and the PO ran the same size too. The rub is more noticeable when turning up an incline, but I've heard/felt the run on flat ground too. What would cause this "out of the blue"? Are my springs wearing out? FYI...I replaced the shocks less than a year ago, and bought the tires in March.

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?

So changing the oil in my truck the other day, I noticed the exhaust clamp at the union between my down pipe and first section of my exhaust has been rubbing the trans cooler line and there's a Nick in the granny pan. Lookin at the rubber grommet on the hanger, its stretched tight and looks like the exhaust has shifted over. What could have done this or possible fixes?right by now it's got a gob of high temp silicone acting as a stand off. Don't wanna put the new line in until I have the situation remedied.

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....
Ford 7.3L Power Stroke (1999-2003) :: Light Metal Rubbing Noise Coming From Front Left Wheel
I have developed a sounds that sounds like metal on metal. Not a grinding but more of a "swish swish swish" light metal rubbing when the truck has been running a mile or two. I can barely hear it over the radio but its very noticeable when the window is down. It is not affected by the pressing the brakes and it gets louder and faster in direct portion to speed. It will occasionally leave and start right back up. I touched the front rim around the hub and it was hotter than I wanted to hold onto. It didn't burn but it was hot. It was 105 degrees that day. Here is what I have done.
I replaced that front hub in 2010 and probably have 50K miles on it. I did the 3-9 test and there was no noticeable play. I spun the hub and while it seems to spin ok it does seem a little dry.... I will pull it tomorrow and see what it looks like.
I pulled the calipers off and the brakes pads are at half way and there is no burnt smell. I spun the rotor and it seemed flat and straight. I do have a small tiny lip all the way around them on both sides but I figured that's normal with 265K. I pulled the pins and they were dry but they didn't seem to be sticking. I cleaned them up with the boots and am going to replace them when I get some brake grease tomorrow. I have not looked real hard at the caliper but I plan on pressing that with a C-Clamp tomorrow to check it. Since the rotors and pads looked OK, I assumed there was not a stuck caliper although haven't ruled it out. The axle behind the hub seem to spin freely before I removed all this stuff and the hubs are not locked.
I think I covered it all .. I also thought it could be a rock or stick but nothing came out of my caliper or rotor when I took them off ..
Ford 7.3L Power Stroke (1999-2003) :: Back Doors Won't Open From Either Side
I have always been afraid this day would come - that the engine would outlast the door and window systems.
I have never previously in life wanted a vehicle with electric assisted windows and doors for this reason - remember when those were expensive foo-foo options on a vehicle?
Anyway the back passenger door window has not worked for a couple years now. Not too big a deal.
A month ago the back passenger door could no longer be opened from either side. Not too good and I couldn't see much of a way to ever fix it.
This morning the back driver side door won't open from either side. The lock only half-heartedly wants to unlock via the powered system though it can be fully pulled up manually (not as possible on the passenger side rear).
Next up will be the front doors...

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.
Ford 7.3L Power Stroke (1999-2003) :: Cannot Remotely Lock The Doors After Driving For Thirty Minutes
I replaced my gpr on Friday night and my remote to lock the doors worked just fine. Saturday morning they unlocked just fine as well drove it thirty minutes and went to lock my doors with the remote and it didn't work. So could this just be crazy timing for it to stop working or could it be related?
I have a 2000 f250 4x4 I've tested with all three remotes I have for it and none of them work where would I start to test and see if it is just bad connections or dirty ones?
Ford 7.3L Power Stroke (1999-2003) :: Rattling / Clunking Sound From Front Left Wheel
I've had a rattling/clunking sound from my front left wheel recently so I jacked up that corner. As soon as the tire elevated off the ground the bottom fell inward. I could easily push the top of the tire inward and pull the bottom of the tire outward. Does this lead to a bad hub or bad ball joint(s)?
View 10 RepliesFord 7.3L Power Stroke (1999-2003) :: Front Driveline Has Tiny Bit Of Slop Where Splines Go Into The Yoke / Rattling
While chasing rattles I found my front driveline has a tiny bit of slop where the splines go into the yoke. (There is a bellows seal there just like the rear driveline so I am assuming it is a splined shaft into a yoke). Pounding on it with my fist there is a definite rattle and grabbing both halves you can feel a slight bit of play while twisting it back and forth. The rattle sounds a lot like the one I am hearing when I hit small bumps. Is this normal or should there be zero slop in that joint? By the way the u joints feel and look solid.

00' 7.3 is acting a little strange lately. i was towing a 15 foot trailer the other day for about 250 miles that wasn't all that heavy and my foot felt like it was very close to the floor. I had it to the floor and the truck would only go 60. now even without that trailer its better but still i feel as if i have to really put my foot down into it to speed up. if i go all the way to the floor in o/d it'll downshift and start speeding up but very very slowly then i run out of pedal and am at the floor, a lot slower than before. Before i wouldn't get to the floor and id already be moving pretty good. but now i gotta keep it pretty much 3/4 way down and keep it there to get up to speed and stay there. truck has 253k no tuner or programmer just 6637 intake and an exhaust, ww2. leveled on 35's. the tranny isn't slipping or at least doesn't seem to be. She doesn't shift perfect but its not anything crazy bad for stock with 253k on it. maybe something wrong with the actual pedal? or hopefully not but maybe the trans or motor , or maybe a sensor or something?
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: 2000 - Smooth Idle But No Power
I purchased a 2000 excursion with the 7.3 a couple of weeks ago. The guy said originally in the add that it need #2 and #8 injectors replaced. When I went and looked at it he had already replaced them and said the it still has no power and needed the remaining 6 replaced. I purchased it as it was a good deal thinking I should be able to get it fixed for worst case a set of injectors. BTW the engine has little to no blowby and starts easy and idles great.
The problem it it will not build any boost (has external boost gauge). Actually the gauge only shows vacuum. With the truck in park or neutral you can slowly rev the motor to 2500rpm and all seems fine but as soon as you break past 2500rpm it sound like it is missing and starts blowing white smoke. The smoke smells like when a diesel heater runs out of diesel. If you try and drive it it has NO power and will not move out of its own way and will eventually start like it is missing and blowing white smoke.
The previous owner replaced the following:
#2 injector
#8 injector
UVC gaskets
MAP Sensor
Wastegate solenoid sensor
The first thing I did was start looking at the no boost issue and pulled the turbo. I deleted the EBPV while i was there. Also the turbine wheel was in very bad shape so i replaced the turbine wheel, shaft, seals, bushings and installed a new compressor wheel 5+5 wheel off ebay. Reinstalled turbo and the symptoms are the same. I also replaced the clamps on the spider with Tbolt clamps instead of the worm gear styles and it psi tested all piping and intercooler to 30psi with no leaks. Also the up pipes have already been replaced with the bellowed style so there are no leaks and it has a 4" straight exhaust.
I have since ordered oring kits for the injectors and also ordered the fittings for the fuel bowl so i can check fuel pressure. it has a new air filter, oil filter, oil and fuel filter installed.
The ICP sensor has oil in the plug but if i unplug it the symptoms are still there.
I have also used a scanner and the ICP pressure is approx 500psi at idle and the duty cycle is about 11% at idle. Also the HPOP looks to be new as it is very clean compared to the surrounding parts and i have checked the HPOP reservoir and it is full to withing 1/2" from the threads.
2000 Excursion
7.3
205000 miles
I am assuming that the injectors are original other than #2 and #8.

Iam looking at a 2000 7.3 Powerstroke that has some problems first it is hard to start cranks like it has a dead cyl. Second after starting it has no power not even enough to move. At first it would only run if held wide open but once it warmed up it would idle and rev and move but barely still had a miss. The weird thing is it did not smoke blue-black or white also no strong smell of diesel and no smell of oil at all. The truck has 230ish miles and there are no maintenance records.air filter was new.
