Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Leaking Rear Differential
I'm trying to figure out what axle I have on a 2002 f350 single wheel 4x4 so I can order a replacement seal. So this morning I got to work and noticed that am oily guild was dripping from the front of my rear differential where the drive shaft hooks into it. I figure it the seal, so when I went to look up the repair kit they list several different axle options because of gearing, what axle I have as there wasn't a in owners manual with the truck. Who can I find out what axle I have so I can buy the repair kit for it...

My truck (02 7.3L cc) started making a grilled ding type of vibration when I would let if the throttle. I felt the axle going into the rear differential was a bit loose, so I took the cover plate off. The pictures below show where the pinion I think is hitting, sort of like the bearing is allowing front to Rear differential scaring from movement. Rear movement.
How difficult is a rebuild, and is there anything I should be careful of?
Ford 7.3L Power Stroke (1999-2003) :: Rebuilding Rear Differential?
The rear differential on my truck has been whining for the 2 years I've owned. The fluid has been changed but of course that didn't really solve anything. I'm trying to decide if I want to rebuild it. Was looking at buying the USA Standard brand rebuild kit, ring and pinion, and axle bearings and seals. How hard would/will this be to do myself?

My hood insulation is ripped up and as one of those projects I never got around to. It has shredded and pieces are down in the valley and in the engine compartment. Some of it smells now because it has gotten hot. I would like to clean it out and replace the pad. What is the best way for me to clean it. Do I take it to a truck detailing place or just spray it with gunk and take it to a car wash. Also if the latter is the answer then does it matter if the truck is hot. Currently the truck is 30 miles from any car wash so I'm worried about washing it hot. I just realized though I have my pressure washer with me so I could use that. Recommendations?

I'm fresh out of the perverbial womb to this place and only about a toddler when it comes to my truck. However I do want to learn! I just recently invested in an 02 XLT F350 7.3L. I'm in love with the truck except the leaning forward aspect. I am debating on leveling it via lowering the rear. Any thoughts? Things I need consider that will happen if I do? How would you do it? Would you do this over raising the front? I've heard raising the front can mess with the suspension geometry and that's not a good thing to do!

I am on the fence with getting rid of my 7.3. Here's why. Whenever I crawl underneath the truck or look under the hood I see all these different oil/fluid leaks. She has less than 200k miles and I use her to tow my boat to go fishing.
Right now I am trying to weigh if the truck is worth keeping or selling and then getting a new/newer truck.
Here are some leaks. One is obviously oil and coming from what I guess is the front main seal. I really don't know. The other leaks going onto the U-joint look like oil leaking down the axle from the front differential.
I'm growing a business and not sure if I have time to play mechanic. However, everyone I talk to always exclaims, "You got a 7.3?! You luck SOB!" and I am kinda getting the feeling letting her go would be a mistake. FWIW, she is paid off.
Other than a slight wobble in the steering wheel at speed, she runs like a hoss.
Ford 7.3L Power Stroke (1999-2003) :: Leak On Front Differential Passenger Side
My 7.3 has a leak on the front diff passenger side. It went into a shop for repair and they did both seal but the passenger side came out with a worse leak than it went in with. So just looked this morning and small pool of oil under the ujoint area on the concrete. Its booked in again to be fixed under warranty repair (place that fixed it, repair came with 2yr warranty) on Wednesday next week - was the earliest I could get.
Question - can i keep driving the truck? I'm making a wild assumption that I can unless I use 4 wheel drive. My intention was to just keep topping up the diff to ensure there is fluid in it. It's the work truck so wouldn't be good to be without....
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Adding Hide Away Strobes - Enter Wires From Rear?
I'm currently adding some hideaway strobes into my 02 POV and was wondering if any good place to enter wires from the rear of the vehicle? I'm not wanting to drill any holes and worst case I'll go through the firewall with my other runs and run down my door jam. All my connections are behind my rear seat.

I currently have the rear axle shafts off the truck. I took off, cleaned then put on the rear diff cover.
I live in an area that does nothing but form rust anywhere and everywhere in very little time.
I don't want rust forming in the rear diff gears - can I fill the rear diff up ? Or will it leak out of the rear shaft holes ? Can I fill it up halfway then ?
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - Rear View Camera In Head Unit Comes On When Step On The Brake
2002 F250 diesel ... I found these two plastic pieces yesterday on the floor near the 4X4 shifter. I noticed the other day when i step on the brake the rear view camera in the head unit comes on, so i am thinking they are either a part of the brake switch on the pedal assembly, or something to do with the shift tube.

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?
View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F250 - No Power To PCM Fuse
I just finished a cab swap and I'm having a little trouble. Here's a link to what I've done : [URL] ....
KOEO the WTS light, battery light, SES light all stay on and no power to fuel pump. No communication with PCM (using AE). All fuses are good, but no power to PCM fuse (#22). When I apply 12v to #22, the truck will start and idle - but poorly because I still don't think fuel pump comes on. The idiot lights all stay the same.
I did get to pull codes while it was running and got stuff like IAT circuit high (its not plugged in), fuel pump relay short to batttery, and a few other short to battery things (park assist stuff IIRC). I thought that might have something to do with the redneck idea to boost the fuse with an external power source?
Just thinking while typing, I don't have 3rd brake light hooked up yet (just thought of that, I'll hook it up first) and bed/bumper are not installed, so no tail lights or park assist stuff is hooked up. I'm also not using overhead computer, so it's not plugged in.
My next step is to go back through all of the connectors and make sure something isn't 1/2 way plugged in or possibly plugged into the wrong place(s).
Looking thru the wiring diagrams is not a strong subject for me, but I was trying to figure out how power gets to the fuse and how PCM relay works (does it complete circuit to ground to energize the coil?).
Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Lack Of Power
My issue I'm having - 2002 F350 7.3L has an 8 inch bds lift with 37/13.50 tires. I realize these tires are big but... while driving 100kms/hr or 60 miles per hour and I hit the gas the truck barely wants to move (without pulling a load). Thought maybe a turbo but I have no mechanical skills so here I am!
2nd issue, there's a bullydog chip in that truck when I bought it. he said he always ran it on extreme. I found it puffs way to much black when on extreme and on performance it seems a lot better so that's where I have it?.
3rd issue, the transmission gauge on the dash goes into red when climbing up hills ( I live in the rocky mountains so a lot!) but the bullydog chip says the tranny is only at its hottest 140C? I don't believe that's to hot but I do believe my truck is derating a little while the tranny gauge on the dash is in the red? is there any quick fixes out there for these issues.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Loss Of Power?
I have a 02 f350 7.3 with 296,000k its been running ruff lately with a serious loss in power. The truck sounds good at idle starts up fine but when im on the throttle under load it almost crackles and sometimes bucks. I thought its was injectors replaced them all with stock ford remains but didn't fix the problem. I have AE and it passes a buzz test but i did a KOER test today and it started what seemed like a misfire during the test my ICP went to 2400-2500 and my IPR was at 38%. I have already put a new hpop in a couple month back along with new hpop lines do to a burst, ICP sensor, and i rebuilt the IPR valve. Not sure if this is a problem with fuel or the hpop I have also cleaned the screens in the tank and replaced the fuel pump which were pretty bad....

I have a 2002 F-250 7.3, 159k on it. I bought it in March, ran AWESOME up till now. I was driving to work last week, check engine light came on, truck lost power and started idling rough. I have a buddy who works for a Ford dealer as a diesel mechanic, he came over with his scanner and laptop. #2,#4,#8 cylinders kept coming up saying possible problems are injectors, harness, rings.. He also did an electrical check, that all checked out. He told me to get injectors, so I got 4 injectors (yes I got the correct #8 injector), valve cover gasket, injector harness and 4 glow plugs.
The parts came last Friday, we did the job and it ran great. Drove it Friday night, Saturday, Sunday morning, no issues. Sunday afternoon we were on our way to a birthday party, truck started doing the exact same thing... Check engine light, rough idle, loss of power. After I got home from the party, my buddy came back over, put it on the scanner again, getting the same codes again. Deleted the codes, ran the tests again, same codes, deleted the codes, rant the tests again, same codes.
He said he is going to come by tomorrow with the box to check each individual cylinder.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Power Windows And Radio Go Out Occasionally?
I now have a 2002, 7.3, 250, 4x4 and love it. Everything but the milege. All in all it's a great ride. I have one little problem that's driven me nuts.
The power windows and the radio go out occasionally. Both at the same time. They come back on...... sometimes. Sometimes it takes a day or two. I've checked the fuses and then saw that there is a breaker in the 601 location in the fuse box that's probably causing the problem.
But I thought that it was supposed to shut off to protect that circuit when there is a short somewhere. I don't know where to go or how to locate the short if in fact this is my problem.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Loud Bang And Lost Power In The Transmission
Last year I did some major work on my 02. Painted it, new injectors, 38R, and once it was back together, the transmission went south in a month. Got a Ford reman HD4R100. Shortly after the install, when in reverse, the torque convertor would lock up when you stepped on the throttle. As soon as you let off the throttle, it would disengage. Thinking it was a tranny issue, got another one from Ford. This one has been in the truck for about 9 months. And it seemed fine until about a month ago. It started doing the torque convertor lockup thing in reverse like the last one, but not as often.
Then last weekend it did it every time I put it in reverse. Then yesterday, while pulling away from a traffic light, there was a loud bang, and lost power in the transmission. Once stopped, I found out it has manual 1st and 2nd, but nothing else. No drive, overdrive, or reverse. I personally believe something electrical led to these issues, and ultimately, the transmission failure. I know the truck is not stock, but I do not run it hard very much. When it went bang yesterday, I was not being hard on it. Where to look at what is causing this?
