I just replaced the ball joints on my 02 excursion and I can't get the locking hubs to seat far enough in so that the retaining ring keeps them in place. The ring seats but then works out as I'm driving. There is something keeping the hub from sliding in far enough so that the ring/clip can set deep enough in its groove. What's causing that? Its happening on both sides.
View 10 RepliesMy hubs will not lock when put into 4x4. I disconnected all lines from the solenoid to both hubs and tested them for leaks... All good there. I put a gauge on the lines at both hubs one at a time while the other is still connected and get no reading when switched into 4x4. I checked for vacuum right out of the solenoid, and I get 2inHg when switched into 4x.
The vacuum pump kicks on every time I start the truck, even if I just shut it off and re-start right away. There is no delay when switching my ac/heater controls to different settings or vent locations. So I know there is vacuum. How much vacuum I should be getting out of the solenoid to the hubs?
2004 F350 6.0L....
I'm trying to figure out why my auto locking hubs do not engage. To isolate the problem shouldn't the hub engage if a vacuum is applied to that hub only? A solid 18 inHg is maintained at that hub for over 10 minutes but the selector will not rotate, which suggests to me the seals are OK. What then might be the problem?
View 13 RepliesIn my attempt to remove the auto locking hub on my 2000 F-350 4x4, I found that it would not slide out. I removed the retaing clip and the hub should of be able to come out with a couple wiggles, it seems to have seized inside the hub. I tapped it with a rubber mallet on all sides. Any thoughts as to other alternative methods of removing the hub locker ?
View 14 RepliesI took apart, cleaned and lubed my hubs. My question is: how does the vacuum make the gears work?
Does the vacuum force (suck) the nylon assembly to push the outer gear towards the center of the truck, sliding on the inner gear thus engaging the teeth so that the axle shaft turns the hub?
When the vacuum is gone, does spring pressure pushes the outer gear away from the center of the truck thus disengaging the teeth from the inner gear and allowing the hub to free wheel?
Is this vacuum source constant during 4wd and not present during 2wd or do I not understand how the system works? I have read about a “vacuum pulse” that locks the hubs and another pulse that unlocks the hubs and this confuses me.
BTW, I like the way the Auto lock works. I had a set of Warn Auto Lock hubs on my 78 CJ. They worked on the principle of a set of roller bearings that would lock (pinch) when there was torque coming from the drive shaft. There was no vacuum involved at all. The down side was that when you coasted, the front hubs would be in two wheel drive and so you would not get the engine braking on all 4 wheels. These ESOF seem to have solved this problem.
Oh, I should probably tell you that I just purchased my 04 F250 SuperDuty 4x4 with the 6.0 diesel, just had it a week. It has been 18 years since I owned a 4x4. Before this I owned an 87 F250 2wd with the 6.9 diesel.
My F350 4x4 won't go into 4 wheel drive unless I get out and take them out of auto and put them in locked position and when I have it in lock mode it seams to work like it's in auto mode, when I put the switch on the dash in 2wd, it seams like it's only driving the back wheels....
View 14 RepliesMy 2010 F350 shudders when turning right. From what I read it could be the auto locking hubs not dis-engaging or sticking in the locked position. Tutorials show it's pretty easy to pull the auto locking Hub out taking out the three screws holding it in place. My questions is what type of grease do I need to apply to the auto locking hub once I have them out and determine that is what the issue is?
View 13 RepliesI have a 2013 F250 which has both the Manual and auto locking hub feature. I tried to plow my driveway this morning and after making one pass I put the truck in reverse and could not back up my steep driveway. The truck is showing locked in 4x4 on the dash, the 4x4 control is in high lock but the front wheels will not turn. It has been very cold here lately (-30) and I'm wondering if the vacuum lines for the auto locking hubs have frozen. I have switched the control out of 4x4 and back in several times, and it does lock in again, but as soon as I put the truck into reverse, they unlock again. The hubs are covered with ice and snow right now so I have not yet tried to manually lock them.
View 14 RepliesSo I went to install a front end leveling kit in my 2003 2WD F250, looked like a simple task, except the bolt that holds the lower coil spring mount won't budge! I tried heating the nut, I soaked it with WD-40, tried a 200lb impact and a 30" breaker bar with all my weight. Is there something I am missing?
View 5 RepliesBought a new touchscreen head unit to put in my 06 lariat f250. I have all the controls on my steering wheel for heat and radio and I don't want to lose them with a new radio. This head unit does not have the 3.5mm jack for the axxes unit but has 3 wires labeled swc1 swc2 and swc ground. It supposedly has the converter built in. any views on using a headunit with these wires?
View 3 Replies5.4L... So like many this winter, I had an intermittent crank no start issue. Thought it to be fuel related, based on low fuel pressure readings.
Now all new - battery, iac, cam sensor, fuel pump, fuel filter, fuel pressure regulator, air filter. Cleaned maf, temp sensor and throttle body. Engine starts, but I don't know if the problem is solved.
Fuel pressure is 40 with key on, falls to 35 on start-up, (which seems ok) but then after a few seconds, the pressure drops to 26 where it seems to want to stay. Hitting throttle hard makes it fall to about 20. I can't find any leaks in the fuel lines. Truck seems to run fine while driving.
To me, this doesn't seem good. Engine is not throwing any codes, but the ST fuel trim is running 0 to +3, and as high as +9 on occasion.
Does the consistent drop to 26 sound normal? Should I dig more into it, or just forget about it since truck seems to be running fine?
How to disconnect the door chime? I like to keep my drivers door open while I listen to the radio and it would be nice to not have the annoying chime ring.
View 11 RepliesI broke 2 snap ring plier on this thing, what is the make and model of snap ring pliers used to remove the snap ring off axle in hub ? I have some others but too beefy won't move in there. They need to be long but strong. I've heard Snap On Item: SRPC9000A works but I don't know of any Snap On guys around here and I need to get this thing done.
View 10 RepliesI have a 2008 6.4 Diesel 4x4, and the TC is not locking. The ABS sensors were changed prior to me purchasing the truck as well as the dash and reflashed. I have recently changed the following within the last two weeks:
Internal harness
External harness
TCC solenoid
Tranny filter
I get no codes, but the ABS light is on, and the speedo doesn't work. I know on OBS trucks, the clock spring could affect it, but I am not sure about this newer ones.
Driving home from work yesterday, dry roads, truck unloaded, running around 50mph, had a dog almost run out in front of me. I hit the brakes hard and came to a stop. But, I noticed that my brakes did not lock up the tires. This was a bit of a surprise. My former 2003 Cummins would easily lock them up. Is my truck an anomaly? Can lock up your tires during a hard/panic stop?
View 14 RepliesI have a piece of a warn locking hub that is stuck in the wheel hub. It is stuck in a Ford F-350 super duty SRW 6.8 V10 with a Dana 50 8 lug front axle. Everything seems stock, but we bought this beast late in its life. I have removed the locking hub cap, the inner locking gear, and the metal retaining ring that holds the outer gear in place. The other side just falls apart as it should at this point.
I have tried building a custom puller utilizing the 6 hex cap screws (that attach the locking hub cap) to pull in on two 1/8" thick c channels held off with a 1/2" bolt pushing in the middle of the c channels on the axle. In one case, I sheared off the bolt, and bent the c channels. I tried it again and that time broke several of the hex cap screws off.
I have ran through penetrating oil, wd-40, propane (for a torch) and carb and brake cleaner as I tried heating up the hub while applying penetrating oil and letting things sit, then spraying out rust and such with carb or brake cleaner to loosen things up, then repeating the process over and over again. I have done this process several times. It worked on the center where the axle goes through the inner gear, so now the inner gear is now loose from the axle. But the outside is still suck like no other.
Lightly hitting on it with a 3lb sledge to crack something lose has done nothing, and left me struggling not to beat it much harder with a bigger hammer with a longer handle.
As a note, it took weeks to get the center locking gear to fall out after doing the oil, heat, and spray cleaner process, then driving with it locked in, and it took two attempts and hours to get the cap off from stuck hex cap screws, several which I had to drill out in the end after even an impact screw driver would not work. The U-Joint is bad, and I can't lock in the 4WD which is problematic at the dump and on job sites when it is muddy especially when we are towing a maxed out 5k single axle trailer that wants to dig in to the mud too.
I went to replace my driver's hub bearing last night. Found pieces missing from the locking hub (manual). I ordered them last night it's the snap ring and washers but will not be here till next Monday. Can I run the new bearing with out hurting it. It has already ruined the seals on that side I just don't have the time to take it all the way down. So if I install the bearing and don't put all the guts in the locking hub (I know the locking hub won't work) Dont need 4x4 right now but need to be able to drive it some. Just don't want to mess up the 250 dollar bearing I just got.
View 2 RepliesBack in March while still plowing, my auto locking hubs wouldn't stay engaged. After talking to the local Ford service shop they told me that it was moisture in the vaccum lines and that it had frozen. They told me to manually lock the hubs and bring it in to be repaired when I had time. I made a appointment in the middle of May and finally got it in last week. Now the hubs are seized in the locked position and they will not warranty the work or parts because they say it was caused by the salt from our roads. Does this sound right?
View 5 RepliesI have a 1999 f250 super duty, that was wrecked a few months ago. I have put the truck back together with the mechanic. The front drivers side was wrecked. The power steering fluid tank was cracked and had to be replaced. Also had problems with a box behind the drivers headlight? I did hard wire it together and it fixed the problems I was having the the speedometer and the transmission not shifting correctly. Everything is put back together now but I drove it today and the brakes locked down after driving it a few miles?
Had to push the truck hard to get it back to my house, a mile or so. If I let off the gas it would come to a quick stop. It is ALL four brakes locking up. If it sits for awhile they unlock but will lock up again after driving. The truck is lifted and the ABS light has come on. It was not on before but i am pretty sure the ABS is disabled on the truck. The wires are hanging down by each tire. This is how they truck was when i bought it. Not sure what is causing the brakes to lock up.
OK I am pretty sure my warn locking hub is shot. I put it in the lock position and I can still turn my u joint by hand. I got the cap off and the otter metal ring out. There was No inner snap ring to take out. So now it should Just come out right?
View 5 RepliesI did my ball joints, and the drivers side oem manual locking hub was a bear to wiggle out but eventually came. When I put it back in after I finished, the wire retaining ring clicked into place but wasn't seated as far in as the passenger side (I could still see the wire). Didn't think much of it. Drove off. 30 miles later I heard a pop and saw the hub rolling down the road behind me.
Stopped and picked it up, went home managed to find a pair of locking rings i kept off my Dana 50, and I just cannot get it to go far enough in for the snap ring to fully seat in the groove. I tried tapping the axle further in, I tried tapping on the steel part of the hub with a deadblow, but it feels like it's in as far as it will go. Not sure what to do, driving without a locking hub right now.
