Ford Super Duty (1999-2016) :: Transfer Case Is Engaged / Won't Disengage
Sep 6, 2015
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.

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.

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.

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.

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.

97 F150 4x4 5.4L ... Just put this truck back on the road after being parked since 2008. While driving at 45 mph, transfer case engaged and is locked in 4wd lo. I did notice a pop about a minute after I started the truck. Drove approx. 5 miles. Transfer case engaged and chirped the back tires, slowed speed to about 5mph. Having it towed home. I'm thinking shift motor???

I've read many posts about ESOF and fault vacuum lines and how that will prevent 4x4 from engaging. I experienced a different problem this past weekend. Here's the situation...
Was about 1.5hr drive up to the mountains. Outside temp when we left the house: 10F. Outside temp when we arrived at destination: 9F. Quite a bit of road grime on the way up from sand, slush, and that magnesium chloride (or whatever they hell they put on the roads in an attempt to keep it from freezing). 4x4 worked fine on the way up. 4x4 light on dash was on, and I KNOW I could not have climbed the snow-covered forest roads without being in 4x4. Also, I could hear and feel the front hubs turning.
On the way home, once I got to where the roads were sufficiently ice free, I turned the dial on the dash back to 2WD. 4x4 light goes out. But I can hear and feel the front hubs are still turning. Toggled the switch back and forth a few times. 4x4 light would come and go with the toggled switch. But the hubs didn't disengage.
When I got back into town (outside temp now about 5), we stopped at a red light and I toggled the switch again. This time, the hubs disengaged. Is this a sign of bad vacuum? Or more an indication of faulty hubs??

I have verified that my AC clutch does disengage (and re-engage), but it seems like the AC is on all the time. Normally you don't notice this in the Northwest because I always overpower it with the heater, but now that it's above 70 on occasion, in vent and full cold, it still blows 20 degrees colder or more than outside air temp.
Is it possible that the clutch disengages but that the bearings are bad and its somehow still turning the compressor? Would a mechanic be able to diagnose this or would I just have to throw money at buying a new compressor? My first indication should have been that I get about 15-16mpg when I used to get 18+ occasionally.

2003 F250 SC Lariat. 4x4, 6spd manual transmission, Manual hubs and manual 4wd shift. The truck shifts into 4wd perfectly. When I shift back into 2wd the transfer case stays in 4wd. If I back up it will go into 2wd.

I have a 2001 F550 flatbed tow truck with a 7.3 and the ZF 6 trans. i put a Luk clutch flywheel pressure plate new throw out bearing new clutch fork New clutch slave cylinder and master set up. When i push the clutch in it is VERY EASY compared to the way it was before. Ane when you push the clutch in and put it in gear you can hear the clutch disc rubbing on the flywheel and if you lift your foot the thickness of a hair the truck takes off. Also i can't engage my PTO because the clutch is not disengaging all the way. there is No adjustments on this set up. What Now.

2002 F350 Super Duty 7.3 Diesel.Transmission trouble. Came off interstate - took foot off throttle at yield and hit gas as turn was clear. Did it fast and felt like hit wall. Immediately lost transmission engagement. Trans did not reengage until below 20 MPH. Tried to speed up and disengaged at 20 to 25MPH - just free wheel - engine wine. Went to 1st gear and would come up normally. Shift to 2nd and could get up to 30MPH and probably higher - didn't push. Shift to drive and trans disengage. No trans fluid leakage and level looks good and clean. What to look for? 126K miles.

I recently purchased 1999 7.3 PSD The owners manual says that the crank case holds 14 qts. I have read on other sites 15 quarts. In my engine 14 is barely at the add mark. The cross hatch area is 2 quarts to the high mark. My question is should I put is 15 quarts to get the level up onto the cross-hatched area or leave it down at the add mark ?? I'm using Motorcraft 15 W 40 Dino oil. and I replaced the filter with the correct Fram filter.

I was thinking my AC clutch has too much gap and was gonna do the "fix it" listed in another thread. However, my clutch wouldn't engage like it states needs to be done. The only time my AC blows cold is when it's cold/cooler outside OR I rev up the RPM's but it hardly stays engaged. I had a friend do a few diagnostics on it, with a paper clip (assuming he did it right) he feels my clutch is bad. But I've read the clutch is either good or bad, works or doesn't work, no in between.
Next, it doesn't seem to blow as hard as it used to. I replaced the blower motor last summer, but even before that, it seemed to not blow very hard. If I have it on low, it's very hard to feel it. With a crew cab and 2 little boys seated in the back, they often end up sweaty and miserable, no matter how far we go. I've read the orifice tube might need to be replaced, or something needs to be cleaned cuz it's dirty or clogged like the orifice tube. But I can't remember what.

I've got a 2000 F250, 5.4L 4x4 with the ZF5 5-speed transmission. Three years ago I replaced the complete clutch assembly, pressure plate, throw-out bearing, etc, and had the flywheel re-machined. Put it back in and all has been well. Only has about 15k miles on it. Earlier this week I went to drive it and all of the sudden it started getting harder to shift and by the end of the trip the clutch will not disengage at all when I push the pedal in.
Furthermore the pedal is much harder to push than it always has been. Checked the reservoir and it's fine. After some searching it seems to most likely be an issue with the master and/or slave cylinder either needing to be bled or replaced. Further reading revealed that bleeding and recommends just replacing the whole system, so I've priced that out. Was it a master/slave issue? Anything else I should check in case it isn't?
