Ford Super Duty (1999-2016) :: 2011- While Not Moving Forward - 4WD Won't Engage?
Mar 20, 2013
2011 F250 6.7L Powerstroke, automatic tranny, Electric Locking Diff
When I engage the On the Fly 4WD switch the indicator panel says "shift to 4x4H in Progress" and everything seems fine but if I am not moving forward when I shift the 4WD doesn't engage. The engine revs up but nothing happens. When I release the accelerator the transfer case bangs like it is going to rip out of the truck. In reverse it is even worse. I am lucky that I didn't gun it or I could have done allot of potential damage. All my other Ford 4WD vehicles engage immediately from a full stopped position. This is quite of troublesome because if you have to shift when your stuck in the mud, your still stuck. If I shift while moving forward it works just fine.
My question is: Does this particular model (2011 F250 6.7L Powerstroke with an automatic tranny) have to be moving forward in order for the 4WD to engage?

My 2001 F250 5.4 has started to make a screeching sound. It only happens when it is in gear (auto) moving forwards or in reverse, and increases in pitch relative to engine speed rather than road speed, and is much more noticeable under mild to moderate acceleration. Maybe I actually mean transmission input speed?
When simply maintaining road speed, it is almost silent. Anyway, if I drop it into neutral while driving, the sound stops, and starts again when I put it back into gear.
From the drivers seat and with the windows closed, it sounds as though it is coming from the engine bay at steering column height, although this is really tough to gauge while actually looking where I am going. With windows open, it comes from both sides of the vehicle.
1st thought is tranny......
2nd thought is a water pump bearing, although there are no apparent cooling problems or leaks.
3rd thought is the alternator bearing, although there are no charging problems.
I say alternator because I recently changed the serpentine belt and noticed that the alternator made a very faint screech-like sound when spun without the belt on it. The main screech was there before I changed the belt. Maybe it gets really loud under load?
So I'm kinda scratching my bean and wondering what expensive piece of mechanics I'm going to shell out for next. If it's #2 or #3, I can do those myself, but if it's #1.... it likely means more money than I have to spare.
I did wonder about removing the serpentine belt and driving a very short distance (end of the driveway and back) to see if I can remove the pulleys, tensioner or other belt driven parts from the equation. Maybe this is not such a smart idea. I'm somewhat at a loss right now.

First off I want to say I love my 11 f350 6.3 srw she's a awesome truck. I pull a small 7x14 trailer for my biz..
(3600-400) is the usually weight, I always use my tow feature. One day last week I start out hit my button in go, but I notice the engine braking/down shifting wasn't working. The trans still shifts smooth n normal the light is on the dash but no tow engage.
I check the transmission wire plug to make sure it'd getting a good connection, it does. I take the rubber boot off next to the shifter look at those wires they look ok not pinch or nothing, so I'm stumped.

2011 F-350 XL, I can hear a squeal coming from the front brakes when rolling forward slowly, believe the pads are dragging on the rotors. If I touch the brake pedal the squeal stops as it does when I turn the wheel. Took the calipers off and greased the slide pins and put it all back together, still got the squeal. What don't I know???

I have a 99 v8 with a 8" lift. I just added a front leveling (mini spring pack) to replace the lifting block (death trap). Anyways after I installed the 2" spring pack and removed the 1.5" block the truck will not go into 4wd. Did I do something wrong? I did not unhook anything. I just unbolted the spring and shocks, lowered the axle down, then installed the new springs. By the way it has the warren aftermarket manual hubs (lock or free). I can hear the t-case engaging and the light says its in 4wd.

I was driving home the other day when all of a sudden all of my electronics in my truck turned off. Turned out when I got home my battery terminal was loose so it ended up shorting out. (fixed that) but when that happened my fuel was just under half way. The next day I filled up and was pulling a 3,000 pound trailer. My gas gauge didn't move at all, all weekend it was stuck at full until I actually went over a bump and it started moving down to a quarter. I knew here was no way I could go all weekend pulling a trailer and only lose a quarter of gas so I filled up again and was only be able to fill up 14 gallons.

On my 99 lariat the 4x4 does not engage. It's got a electric switch on the dash. The 4x4 light comes on when I turn the key on for 3 seconds. But when I turn the switch I got nothing and can't hear anything trying to engage. Where to start or how to test the switch?

I have a 1999 F-250 4X4 7.3 lit Diesel engine. My problem is my transmission will go into reverse great no problem but it won't go forward. I have no problem rebuilding the transmission if that's what it needs, I just want to make sure there isn't a electrical issue from the PCM first?

What are some simple checks, my 4x4 low range does not engage, just stays in 4 hi. 2003 f350 screw v10.

So sometimes the 4x4 takes awhile to engage. Both hubs are free turning (manual to auto). Drivers side only holds a few psi of vacuum. Passengers side 20ish. All seals have been replaced. Was tested right at the nipple on drivers side front. Switching hubs from side to side didn't change anything. 2 mechanics are unsure what to do aside from take a chance at replacing the wheel bearing. It does eventually go into 4x4 but takes awhile for 4x4 to engage and light on dash to come on.

Have 2001 F-250 7.3 PSD, automatic, ESOF (had to replace the original hubs with Warns)have kept up the maintenance,oil, grease, ATF fluid & filter, truck has been virtually trouble free. About 2 weeks ago I decided to go across an area of the lawn, as I was going (in 2 wheel drive)I felt the tires spin a little so I stopped got out and locked the hubs, got back in truck turned t-case to 4 high. had to rock the truck out of a damp area but nothing really.
So I got back to where I came in at (in reverse about 100') stopped put it back in 2 wheel drive, tried to go forward, very difficult, sluggish, got back in driveway had to back the truck in, will not go forward at all now. Checked all fuses, rapped the the t-case motor, no codes. So I thought I'd move the ruck, have a winch that will pull it out by the barn, I could not even move the truck forward by pulling it with a winch. As I said have never had any problems with truck. Transmission fluid is good, clean no burnt smell.

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.

It seems its the 4R100 tranny non pto of course and 2wd version. I drove down the rd. after bleeding the brakes, new caliper front right, came home let it idle for about 10 min, shut her down. Went to move it about an hour later, it went into reverse no problem, then when put it in Drive it revved like it was in neutral. There was no banging, no clunking, nothing to make it seem like something catastrophic happened.
I then did a line pressure test and Reverse was fine 200 psi for sure, in drive mode however it was low like around 50 but had to rev real high to get it to 150 like 3/4 pedal and it would want to seem to go forward at a crawl but nothing more. Next I did the obvious and cheked the fluid, it was about 1/4 quart low so added a bit. The fluid did not stink and was beautiful red like new.
I then tried again... no dice same scenario. Then took off the pan, no metal chunks and virtually no dust on the magnet??? Ok so I figure maybe something with the shift valves? Took them all off and the accumulators as well, all check ***** were in place and all valves moved freely.
Now onto the the solenoid pack, checked all per manual for ohms and all were perfect reads at about 27 Ohms, except the EPC solenoid that is the big one on the pack, it should read about 3-5 ohms but this guy is about 12.5 ohms.
I spoke to a tranny shop in town and they said it would not be the EPC and that I could "unplug" the solenoid pack and It would still move forward without it but not to drive like this as line pressure would skyrocket?
Why this thing would have 200 lbs pressure for reverse and so little for forward I mean? that should mean that the pump is working great, if there was a broken something metal I figured I would hear something rubbing or banging or see some shavings? Can this be a "worn out" valve? or gasket issue?

I have a 1999 F250 Superduty with power tow mirrors. Both mirrors are having this issue. It seems both motors moving the mirrors are trying to run at the same time. I tried replacing the control switch since both mirrors are having the issue, but got the same results. Holding the switch to move the mirrors out causes it to move down and out. Moving it in and it goes up and in. I know from experience with electric on a vehicle that when funny things happen, its usually because it lost the ground.

My truck: 2001 F250 V8 Triton Automatic 4x4
Problem: 4x4 won't engage
Symptoms: No dash lights....nothing happens when I turn the 4x4 switch. When I start the truck I hear what sounds like a motor (transfer case motor maybe?) trying to switch (even though my dash switch is on 2WD)... It tries three times and stops.
What I've done: Checked fuses ...they appear ok to me
I don't have a maintenance manual yet ...
The 4x4 used to work up until about 2 weeks ago. Started having a hard time getting it to go into (and out of) 4x4 and then it just stopped all together.

2005 F-250 King Ranch Diesel ... My truck when I got it the 4x4 wouldn't engage. I replace the front inner seals, and the lock outs. Still wouldn't work. Took the shift motor off and freed it up and it worked fin till today. Changed the shift motor and still nothing. This truck has been nothing but problems since I have had it and now this ... Truck is going on the market soon and would sell better if the 4x4 worked ...

How to diagnose a vacuum leak without a vacuum leak diagnostic tool.
My ESOF won't engage, AC/heat blowers default to defrost - classic symptoms. And while we can leave without AC/heat, we really need the ability to engage 4x4 low, especially as we get higher into the Andes and the roads unsmooth.

F-250 2005 XLT 5.4L 4X4. Had ford for a few years now (Escape as a personal vehicle and econoline as business vehicle). Now I'm having a little problem with 4x4. It wont engage. Worked fine last week and now nothing! I did check all the fuses and when i switch to either 4Lo or 4Hi I can hear a clicking sound behind the switch but feel like it's getting blocked or something. Tries a few time then stop...

I have a 04 ford f250 superduty... I tried to use my 4x4 today and the front wheels would not engage using the ESOF. The light comes on in the dash saying its in 4x4. i do not believe i have a vacuum leak because it doesn't switch over to the automatic setting for defrost. what else could it possibly be I'm stumped at this point.

4x4 will not engage. 4x4 light on dash does not come on. Can not hear motor switching into 4x4. Check fuses under dash all looked good.
Truck is a 2004 F250SD V10 ....
