Ford Super Duty (1999-2016) :: 2001 F250 - Power Feed To Transfer Case Relays
Sep 24, 2015
2001 F250, 7.3L ... After much diagnosis, I've found that the 4 positive feeds to the transfer case relay base have no power to them. The fuse that feeds them (#17 CJB) is fine and when I jump from the fuse hot side directly to the transfer case motor contacts on the relay base, it shifts fine. As far as I can tell, there is only one wire leading from that fuse so there must be a junction block somewhere that splits it into the 4 wires that feed the relay block. I've looked underneath and found nothing. How the 1 wire gets split into 4? On diagrams this junction point is labeled, but I don't know where to find that.

We have a 2000 F250 7.3L Diesel. A few years ago we switched out the auto hubs for manual Warn hubs. We've had no problems with 4x4 since that time, until now!! The 4x4 Hi light is on and the transfer case is engaged. Since the hubs are manual we have them unlocked, however we can't get the 4x4 to disengage. At one point, tried changing to low and it hesitated but finally went in to 4 Lo, then we had a hard time getting it out of 4Lo and back to 4 Hi. Here's what we've tried--checked fuses, checked and replaced relays, checked wiring connection at the transfer case. Husband used volt meter to test power at transfer case wiring connector--showed 0.5 volt of power with the key on. No change in reading. Checked power at relay--about 14.5 volts there. Took truck to repair shop but their computer could not communicate with the GEM.

Made a short run to get lumber yesterday and when I got home the truck smelled hot I checked it out and found a transmission oil leak at the rear of the transmission in front of the transfer case. can not really see what is leaking only has 22,000 miles. What may have happen. 2011 F250 4x4 6.7....

I have a 5.4L 2001 F250. I recently replaced the starter and this morning when I turned the key it just started clicking. I had this issue a couple weeks ago and swapped the battery from another truck and it started fine for a while. But after this morning the relays are still chattering even when the key isn't in. I believe it's still the battery ....

For about a week or now i have been trying to track down a sound from my truck, i had another post up and was finally with jhl3 able to determine that the sound is coming from my transfer case. The other thread with video of sound is located here : [URL] .... I've got a little bit of time to mess with i now
Quick rundown, began hearing odd sounds about a week ago, determined that it is transfer case. Front hubs are unlocked, esof switch is set to 2wd. Can not turn front drive shaft. I just put some zip ties on front drive shaft and went for a short spin, determined front drive shaft IS turning. Hubs are not locked and 4x4 is not engaged, did the sharp slow turn test, no feel of pull from front end.
Im not quite sure where to go from here, going to check connections at tcase motor and some relays.

Originally it would light up on the dash, the hubs would lock, but the transfer case would not shift in to 4 wheel. Followed the troubleshooting I've found, was receiving power at the connection on the shift motor but it was not turning.
So I went and bought a new motor, installed it, still wouldn't turn. (with the motor off the transfer case but electrically connected). So I found a few more replies about the relays, swapped them, nothing.
Removed the covers and manually flipped the connection, nothing. Now my hubs are locked, transfer case is not, and I get nothing when I change the switch on the dash. (no lights, no hub click shift, no 4 low, nada). All the fuses are good, just doesn't work.

New floor mats. My truck is going to be 10yr old and has the original King Ranch floor mats. I want some heavy duty rubber ones that will fit around my manual transfer case lever. I ordered the Weathertech digital fit liners and I am not happy with them so they are headed back tomorrow. They have a heavy duty all weather mat but not sure how it will work with my shift lever on the floor. Husky liners/mats look nice and heavy duty but won't accommodate the floor lever.

The transfer case on my 2004 F350 6.0L 4WD DRW, 230K miles, just blew to pieces Sunday night. See images below. What could cause this?
I just had the front drive shaft rebuilt with new universals and ball. It was making a metallic squealing noise after this.
I noticed that the front drive shaft did not spin freely when parked in nuetral and set for 2WD. I thought the front drive shaft would only engage when in 4WD.

Trying to stay up on my maintenance on my '11 f-350 diesel. It just turned 59k. I can only find Ford's recommended service interval for changing the fluid in the transfer case listed in the "Special Operating Conditions" section of my Scheduled Maintenance Guide for towing, delivery, off-road and dusty conditions at 60,000 miles. I tow some, but maybe 20% of the time, I end up driving a lot of stop and go though.
So I found this nice how to online "Guzzle's Transfer Case Fluid Change" - it's for a 02 heavy duty, is it about the same on the newer diesel trucks?

I just changed transfer case fluid on my father's F-350 for the first time in 13 years. (over 230k). Removed fill plug first and fluid gushed out of the fill hole unexpectedly. Did not have catch pan ready, so made a mess. I thought it was just over filled form the factory, but too much was coming out to be simple overfill. Almost 2 qt came out of the fill plug.
Did some google search and found many Ford trucks have failed transmission output shaft seal and transmission fluid leaks out to transfer case, causing transfer case to overfill. I am yet to check transmission fluid level, but considering how much came out of it that probably is the case.
Now, how bad of the problem this really is? Will overfilled transfer case cause some serious problem? 4x4 is rarely used (once or twice a year in winter) on this truck and from what I understand transfer case doesn't really do anything in 2WD other than just passing output from transmission through.
There are no fluid leaking outside and repairing the seal would be a too much of work for me.
Also changed rear differential fluid for the first time and I was surprised how clean the fluid was. There were thin layer of black sticky residue (sludge?) covering everything, but the fluid itself looked clean and no visible metal shavings. I guess that is why Ford said it does not require change under normal condition.

Truck is an 03 F350 with the 6.0. It sometimes sounds like the shift motor on the transfer case is trying to engage. It has the vacuum system which is blocked off. Warn aftermarket hubs. Switch on the dash with 2wd, 4wd and 4 low.
It's kind of an off and on thing. Try to engage for a few or more seconds then nothing for awhile then repeat. It sounds like it's at the transfer case. It could very well be coming from firewall/engine bay area as well. Is there anything between the dash switch and the motor?

I'm in the process of changing my shift motor on my 04 f350. I can't get it off because of a broken bolt. The previous owner must have done this before, and snapped the head and some of the shaft off, so it's basically an alignment pin that's recessed into the hole on the motor. For some reason it's holding the motor on, even though I don't think the hole is threaded. Any way to get it off. I'm thinking that taking a MAP gas torch to the casting on the motor may be my best bet.

I have read everything there is on this stupid esof 4x4. But I'm not getting power to the relays. I have checked every fuse listed and have no corrosion or anything. Is it possible that having a ,door ajar light on, constantly cause this I'm stumped.

I have a 1999 f350 with the 5.4l engine. I have no power to the fuel pump or fuel pump relay. I have battery voltage to the pcm relay. I don't know what else to test because I don't have a proper wiring diagram.

Cruise won't power up. Tried entering diagnostics but did not get any flashes. By-passed switch on master cylinder, did not make any difference. Horn honks. Brake lights work correctly.

I have a 03 f 350 6.0. My 4x4 wont engage. I checked my fuses all are good except 31 no power. Is this the culprit?. I get power at the 6pin pig tail on shift motor, but the 2pin pig tail doesn't get any power at all. I pulled shift motor off manually put power on it and it works. I also replaced both 30amp relays under hood...

Changing from manual windows to power? I don't want to swap doors because of the repaint issue but wondered what is involved, if it's even possible. I just read how to convert the rear windows on a Super Cab to power and it got me wondering about the front.

I have a 2001 f250 super duty extended cab with the v10. Over the past week it has been running fine and it will all of a sudden lose power and dies. I've been able to start it back up once right away and a few times it started up after a few hours of messing with it.
So, after the truck dies it will crank and crank but will not start. We have checked fuel pressure and nothing. Then we applied direct current to the fuel pump and it turns on. Then we applied direct current to the fuel pump slot in the fuse box and got a fuel pressure reading of 40 psi. But when we crank we have no pressure.
When we apply direct current to the fuel pump slot in the fuse box the truck will only crank and not start.

The truck runs but After staring and during idle there is a heavy relay click and the speedo jumps to 20 or 30 mph. Afterwards on a 30 to 45 sec cycle there is a relay clicking in the area of the PCM relay.
Speedo jumps to 10mph and radio resets. 15 to 20 seconds later there is a light click behind the dash ( no speedo jump or radio reset). Rinse and repeat...
I have tried to locate which relay is setting it is either the PCm or possibly the pcm and the icm. Can't tell. Popped and swapped for s&@$s and giggles but no change.
1999 7.3, 308,000 miles. No mods. Original injectors and no other major repairs.

OK so my 2001 F250 was leaking power steering fluid from the lower portion of the gearbox (where the pitman arm attaches).
I found a thread on this forum where it showed how you could change the seals out WITHOUT taking the gearbox out.
So I got the pitman arm off with a heavy duty puller. Then I scraped out the 1st rubber seal hoping to reveal a snap ring behind it. Well, the seal is 99% scraped off, but there is not evidence of a snap ring. It does seem like there is some metallic ring holding another rubber seal in behind it. But again, I can't find the little open spots that you put your snap ring pliers in to get snap rings out.
How do I get this metallic thingy out???? I already broke a small drill bit trying to drill it out. It just doesn't seem like the best way to go about it.

I have this 99f250 and it has a 273f, the transmission side of the case has threads stripped so I am about to remove and retap them. While its out should I consider rebuilding this thing? 197k miles, operates decently although the rear bearing on output side is my first thought to replace from mileage only.
