Ford 7.3L Power Stroke (1999-2003) :: Switch From Manual To Auto Locking Hubs?

I know this is going to sounds lame, my wife can't turn them, they have cover over it that has to be unscrewed to get at 'em. It would be nice to shift in and out "on the fly" as weather condition change.

Is it a difficult change?

Ford Excursion :: 2003 - Manual Locking Hubs Won't Turn / Stuck?

On my new to me '03 Excursion (I've owned it for 1.5 weeks now), I'm starting to get through the 1st level of issues (Wandering - fixed, Speedo/ABS issue - still working on that, changing the rear diff fluid this week, hopefully).

Now, I want to look into why the manually locking hubs won't turn. When I brought it up to the Previous Owner, who was about as mechanically inclined as my Golden Retreiver, he said "these are auto locking hubs. I never turned those things before".

They are frozen in the non-locked position, so I have to pray that I never need to actually manually lock them.

Any lucky experience at un-freezing stuck hubs? I've started the liberal application of PB Blaster process.

Ford Super Duty (1999-2016) :: Manual Locking Hubs Code

I just ordered '00 F250 SC 4x4 SWB XLT with the factory standard manual hubs. The hubs show up on the vehicle order confirmation as code "21M MAN LOCKING HUB". I can't find this code in the ordering guides anywhere but kbb.com shows this code as "Manual hubs delete. Required with 213 shift-on-the-fly". I want the manual hubs. I think ##### is incorrect. For my piece of mind, could someone who has also ordered the factory standard manual hubs verify that the code is indeed 21M. And for those who ordered shift-on-the-fly, could you verify that 21M does NOT show up on your order confirmation...

Ford Super Duty (1999-2016) :: Front Axles Are Rotating All The Time / Manual Locking Hubs?

I've noticed my front axles are rotating all the time even when the hubs are in auto and supposed to be unlocked when in 2wd. Is there a rebuild kit for these so they will unlock the axles or do I need to buy new locking hubs?

Ford 6.0L Power Stroke Diesel :: Water In Auto-locking Hubs?

I got new auto-locking hubs. The updated ones. As I proceeded to replace them, I pulled out old ones and when driver side came out, there was like 1/2 ounce of water that flowed out from where the auto-locking hub would sit. Strange. I had changed out lines, vacuum pump, vacuum solenoid and reservoir. All new and dry. I blasted both sides down with brake cleaner to clean off old grease, let dry and installed new auto hubs. So far so good. Will test the ESOF feature another time. I was wondering where this water would come from? Other side of wheel hubs are dry.

F Series :: 1995 F150 Manual Locking Hubs Won't Engage

Have a 1995 F150 with 83k with manual locking hubs. Haven't used them in almost a year. Today turned them to LOCK, normally very stiff, but this time easily turned with two fingers. Front wheels would not engage. Local mechanic put it on a lift, manually switched each hub from LOCK to FREE several times and they work fine now.

Ford 6.7L Power Stroke Diesel :: Locking Hubs To Auto Damage Drive Line System Components?

Just notice this in the manual page 302 The vehicle should not be driven in 4x4 high or low with the lock hubs set to auto as this condition may damage driveline system components.

Page 303 It then goes on to say !!

Automatic operation of the hub locks is recommended and will increase fuel economy.

when using 4x4 once in awhile LOCK or AUTO

Ford 7.3L Power Stroke (1999-2003) :: Grinding When Hubs Are Locked

Warn Premiums, installed them and now the 4x4 is engaging, but still have a grinding issue. When the hubs are locked and the switch is in 2 wheel drive, the frond end is grinding, if I switch it to 4 hi, the grinding goes away.

Ford 7.3L Power Stroke (1999-2003) :: ESOF Won't Engaging Hubs?

I have my vacuum system back up and working and using my vacuum pump I determined my lines are all good. They hold a vacuum fine, but my ESOF isn't engaging my hubs. I guess that leaves either the selector on the dash or the seal at the hubs.

If it is the selector, I should just be able to just disconnect the vacuum line at the selector and use my pump to engage my hubs. How much it is supposed to take to activate the hubs?

Ford 7.3L Power Stroke (1999-2003) :: Replacement Hubs - How Are They Holding Up

To those of you that have replaced your unit bearing hubs on your 4 x 4's; are they giving comparable service to the OEM units? I'm replacing ball-joints right now and it would sure be easy to slap on some new hubs. The only issue is I have 130k on the originals and have been lubing them through the ABS port for the last 20k miles - the hubs seem to be in good condition. I've noticed some posters stating that since lubing an already good hub, that they are now getting a lot more than the standard 150k out of them. I also worry about replacing perfectly good US bearing hubs with most likely a Chinese bearing hub (Timken or not!).

Ford 7.3L Power Stroke (1999-2003) :: Vacuum Shutoff For ESOF Hubs?

I am thinking on installing a shutoff in the vacuum line that supplies the hubs so I can use 4LO for backing uphill with a trailer without having the hubs engage. Its either that or a switch to disable the PVH solenoid.

Ford Super Duty (1999-2016) :: 2003 - Locking Hubs When Trying To Engage To Shift Into 4 Wheel Drive

I recently purchased a 2003 F350 FX4 Dually with the 7.3L Diesel. It has locking hubs and electric shift in the cab.

I have had locking hubs before that you had to engage to shift into 4 wheel drive and I have had trucks without locking hubs.

My truck didn't come with a manual, so I am looking for instructions for the proper use of this system.

Ford 7.3L Power Stroke (1999-2003) :: Replacing Front Wheel Bearing Hubs?

I was getting a growl/grinding noise from my front hubs (driver's side I think) when I do a slight right turn like going around a curve, not turning around a corner. Just started happening the last week after returning from a 4th of July roadtrip. First thought was wheel bearings going out and started reading up on the forum here to see what was needed. Last night, I started getting a continuous growl when I was 5 miles from the house so just pulled up and parked it. I'm assuming (without pulling anything apart), it's the bearing assembly and I can get the Timken version at Autozone locally.

The problem is I generally do my heavy maintenance at our family shop in San Antonio but I live in Austin so will need to do this in my driveway. I have all the basic tools, just need to know how involved it is to do in a driveway instead of a shop. Thoughts?

Ford 7.3L Power Stroke (1999-2003) :: 4wd - Tires Not Pulling When Manually Lock Hubs

My transfer case engages the front drive shaft spins but even when I manually lock my hubs neither of my tires will pull! I was thinking either the hubs are shot but I was told it could be the 4wd locking solenoid??

Ford 7.3L Power Stroke (1999-2003) :: Trans Not Locking In 1st Correctly

I bought this truck with 200000 miles and its been flawless, its now 900 short of 600000.. I use it to haul everyday.. nothing heavy mostly a car or truck and every once in a while a skid steer. I got 560000 out of my trans, i take it easy. lol

at 350k I installed a Jw valve body drilled pump, tripple disc converter and solenoid pack.. at 560k it went, i pulled it and brought to a guy i trust as much as you guys trust BDS.. Ive had what Ive called a vibration since day one, could be a shudder, could be a shimmy.. what ever.. I brought it back and he says nothing would do that from a trans, so I went through drive shaft, new t case ripped apart rear end and its still there and I have just been dealing with it.. about 2 months ago it started acting up in first. when I pull down to drive I get the normal bump and start to go, it feel like the truck slows, then another bump and it climbs normally with the shudder.

took it back and he said maybe a stuck valve in small VB, so I pulled it and went down there and it was fine, I reinstalled and still does same thing. I then put a pressure gauge on it and it swings as it should sits around 70 psi and will climb, only in first it will climb and fall back to 70 like a switch was flipped, and the rest of the gears bleed off slowly or normally.. He then said it could be the big valve body, so I swapped that one out with another and no real change, maybe its a bit more noticeable.

I am at a loss. Could this be loose feed bolts? Could the shudder that I can feel at most speeds be the 1 gear slipping a tiny bit all the time? I am told that first gear is always on.. this truck has been a dream until this trans issue..
