Ford Super Duty (1999-2016) :: 2000 F550 - Squealing Then Grinding Noise Instantly When Hubs Locked In
Having an issue w/ my 00 550. When I lock in the hubs there is instantly a noise, More of a squealing then a grinding. The truck goes in and out of 4x4 no problem and the noise is there locked in 4x4 and not locked in, as long as the hubs are locked in. I can't tell if the noise is coming from the 4x4 driveshaft but there is no noticeable play in the u-joints or the u-joints in the front axle. I did notice when I spin the 4x4 shaft by hand the passenger side joint spins slower then the driver, not sure if that's normal or could be the problem.

About a month ago I bought a 2004 F-250 160xxx from a reputable Ford dealer here in town. The dealer performed a safety and emissions inspection, and spent about a grand on other repairs, as a condition of my purchase. Today I had it in the shop for an instrument cluster issue (at a different Ford dealer, closer to my house), and was told the vacuum lines were all messed up. Their write up is below:
"Check 4x4 operation. Transfer case shifts to 4x4 and 4x4 low. Front hubs do not engage automatically. Check vacuum at the hubs. No vacuum. Check the vacuum at the solenoid. No vacuum. Perform visual of the engine vacuum lines. There is no vacuum to the reservoir. Vacuum line is routed wrong from the fuel pressure regulator to the vapor management valve. There is other vacuum concerns. All of the vacuum line routing needs to be inspected and corrected."
The service rep told me it is questionable whether the 4x4 ever worked, although during the few weeks I've owned it, I could hear gears or other mechanical parts making noise which seemed to me to be in response to me turning the 4x4 electronic switch. She also said there was a vacuum line dangling loose with a screw in the end of it.
Before I contact the dealer where I bought the truck, I am planning my going-in position. But I wanted to get a sense of a) how serious of a problem this might be? and b) how reasonable it is that the dealer didn't catch this issue before I bought the truck while they were in their fixing other things?
The dealer who sold me the truck made it very clear that the sale was as-is, and I took it to my mechanic prior to purchase, though unfortunately he only had time for a cursory look at the engine. Obviously he didn't look closely enough to find this issue.
I'm not sure if I should ask the dealer who sold it to me to fix it, or ask them to allow me to return it, or sell it back to them, or if I should eat the cost of fixing it. How wrong would it be to try to trade it in for something else?
Ford Super Duty (1999-2016) :: 2004 F250 4X4 - Front End Rumble - Squeaking / Grinding Noise Then Clunking
So to start at the beginning.... Traveled across Canada East to West towing 11000lb travel trailer, no problem. Have used 4x4 in a few campsites to pull out of a pitch without spinning the wheels and causing damage to the site when it has been really wet. All good.
Got to Banff in December and the town was an Ice rink, engaged 4x4 and all good. Crossed the Rockies and the 4x4 starts making grinding noises. Up and down some mountains and squeaking, grinding noise then clunking.
I have manual hubs, disengage and the noise all goes away. Engage 1 hub and no noise. Engage both hubs, noise back.
I bought some needle bearings and went to swap them. Got hubs apart and they look good. No scoring on the drive shafts. They are not dry, but as I have them open, repack them with grease anyway.
Do more research... Remove ABS sensor and repack main bearings with grease. (broke one sensor pulling it out, too cold plastic brittle oops). Still clunking noises.
The universal joints look good, doesn't appear to be any play in them. However, the axle seal (knuckle seal) (F81Z-3254-CB) does move around a lot in it's metal casing. It is tight on the shaft, but with the hub off, I can move it in and out, and move it side to side. If I had ESOF hubs I guess they would not be locking as I'm sure there would be no vacuum in there!
Question is then, would this seal be allowing the universal joint to wobble under load in 4x4 mode? Would this wobble be the cause of the rumble? As it is labelled as a seal and not a bearing, I wouldn't of thought this would have been a loaded point, and the weight would have been taken by the associated bearings and it could be run without this seal? But if it is not this, then I'm still looking for a clue as to what is making the rumble....
Ford Super Duty (1999-2016) :: 2004 F250 - Slight Hesitation When Trans Is Engaged And Tow Haul Light Blinks
I have a 2004 F250 Torqshift trans, 155,000 miles. It has had a slight hesitation when trans is engaged for about 4 years, not a problem the dealer has no fix they said.
Now today for the first time I had a tow haul light come on while driving on the freeway. It would not go into overdrive and the light keep blinking. Later in the day, I let it cool down and it drove fine to the store about 2 miles. When I got in to drive home it had tow haul light go blinking and check engine light came on this time.
I hooked up my code reader and it's giving codes: P0720, P0751 and P0766.
Should I take it to the Ford dealer, a Transmission shop or have a friend who worked at Ford Dealer do the Work? I see that some people have changed out the TFT sensor and corrected the problem. While the pan is down should I just have all the shift solenoid sensors changed?
Ford Super Duty (1999-2016) :: 2003 F250 - Grinding Noise While Coasting In 4x4?
My 03 F250 7.3 is making a grinding noise when I let my foot off the accelerator and coast in 4x4, I replaced the hubs with new warn premium hubs and it is still making the noise. The noise does not occur when I take it out of 4x4.

I just got a 99 F250 PSD, it had not been in 4wd in a while, now the hubs won't unlock.
My 01 F250 seemed to have strictly manual hubs. Turn right to lock, left to unlock. They may have been aftermarket, but on by the PO. Do I need to put some new Warns on the 99? Or can I lube then up and get them functional.

Ford Super Duty (1999-2016) :: 2003 F250 Lariat 7.3L - Grinding Noise When In Park
The problem I am having is that there is a grinding noise when in park. If i shift into gear then it is fine but shifting back to park very big grinding noise. At the same time I have the Speedometer and fan for the heat not working as well as the heater for the seats.
This problem is so bad I am afraid to drive and get stuck somewhere. I have checked the starter and it is tight ad secure. all fluids are fine. Not sure what this would be? This is the single vehicle i have for work and family.
Ford Super Duty (1999-2016) :: 2007 F250 4x4 Not Unlocking The Hubs Automatically
Brings back memories of my many projects from back in the day. Anyway, my uncle has this f250. He said 4x4 wouldn't automatically lock the hubs in. I tested the vacuum pulse valve on the fender and changed it out. Now the hubs will lock in when you turn the light on the dash but it will not unlock the hubs unless you go outside and manually turn the hubs to engage then back to auto. Only then will the front end be unlocked. I notice small puffs of air blowing back from behind the hub themselves so I was thinking it's time to reseal the vacuum portion of the hubs.

I have a 2010 F250 with 154000km (96000 miles) that we bought last week. When I was looking it over during the purchase I noticed the front axle didn't lockup in "auto", in manual lock it seemed fine so I figured vacuum leak or something like that. Yesterday morning I was in the yard and got a little hung up in snow drifts so just got out, locked the hubs and switched to 4x4 and I think the front end didn't engage at all.
So later on I had it in the shop installing the two way radio and decided to check the front end out a little more thoroughly. Vacuum lines seem fine, hubs turn fine but I notice the axle shafts both move up and down almost a quarter inch, that seems excessively loose to me. I've been doing some research on the internet and it appears the front hubs are serviced as a unit, also some information seems to point to needle bearings within the actual locking hub mechanism itself?
So the questions:
1. Does that front axle shaft seem excessive? What are the specs?
2. Can I replace bearings and seals only or do these units come only as assemblies? Inner hub, outer hub units? Wheel bearings seem fine.
3. With that much play is there a chance the outer axle shafts are worn also?

On my 2008 f250 I can not turn the hubs without a set of pliers...does that mean I need new hubs....
What auto tranny do I have with the 5.4.. is it a six speed...
Ford Super Duty (1999-2016) :: 2005 F250 - A/C Switches To Defrost When 4X4 Is Engaged
My 2005 F250 just had the cab off in December for head studs and gaskets. Its a Crew Cab short bed FX4 so it has ESOF. When I engage 4x4 the blower will switch from blowing air out of the vents to blowing air out of the windshield defrost. Is a vacuum line plugged in wrong somewhere, or is one cracked? Trying to figure this out, its rather annoying

I have a strange thing going on with my hubs i think. I have a 2000 f250 7.3 4x4 that I just purchased. Lettering on hubs were worn out as far as labeled locked or unlocked so I tried to turn the axel to see what position they were in. Drivers side spun freely but passenger side did not. Both hubs were counter clockwise and turning it to lock didn't change a thing.
Figured it was a bad hub so I jacked the front drivers side up. Spun tire with both hubs unlocked and axle didn't spin. Locked hub on drivers side and axle spun. Indicating the passenger side was unlocked. Then I locked passenger side and wheel would not turn. Ok. That seems right.
Jacked up passenger side front tire with drivers side on ground and axle spins no matter if its locked or unlocked. So does this indicate the hub is good and I should look at something else or could it still be the hub. Axle spins all the time and I don't want to wear anything out.
Ford Super Duty (1999-2016) :: 2001 F250 4x4 - Auto Lock Hubs Are Not Working
2001 F-250 7.3. The auto lock hubs are not working on the truck lock hubs in and all works fine. First thought is the vacuum system has a leak or something of the sort. Had truck at the shop they are telling me the GEM module controls the vacuum to engage the auto hubs and the signal is not coming from the GEM and it need to be replaced. It was the GEM causing the problem.

I have a 2001 F250 4x4 and the ESOF switch not engaging hubs, currently I have no 4x4 lights coming on in the cluster when i turn the switch. I am not experiencing any of the vaccum symptoms that most people are suggesting. I When I turn the switch i also do not hear any relays clicking. Relays have been tested, and i waited for the 45 second transfer delay that the manual mentions. ESOF switch has power, and is working properly (I know because I bought a new one in attempt to fix the problem) Basically I have no responses from any of my 4x4 indicators or parts.

I recently picked up a '99 F250 Super Duty with the 6.8L V10 for a song.
The 4 wheel drive hubs are not working with the vacuum. If I use the manual lock on the hubs all is well. I ordered the Innova 31703 CarScan OBD2 + OBD1/ABS/SRS Scan Tool. It says it does Trans codes. I am hoping it will cover the 4 wheel drive too.
Maybe related, the heat is always on. Meaning I feel heat at my feet when the temp dial is cold and fan is off. I can't find the heater control valve to check the vacuum line.

View 6 RepliesFord Super Duty (1999-2016) :: 2000 F250 - ESOF Auto Hubs Not Engaging Automatically
I have a 2000 f250 CCSB 4x4 with the ESOF auto hubs. The auto hubs won't engage automatically. They work fine manually. The transfer case is engaging and correct lights are coming on. There is a little bit of vacuum coming from the vacuum switch but it doesn't seem like much to me. All the dash HVAC controls work fine though. I Lubed and cleaned inside the hubs according to Guzzles directions.
While torn down, I blew through the vacuum port on the outside of the hub and there was little to no restriction. I don't think there is enough vacuum to pull the hubs, but is that possible if all the dash controls work fine? What pressure should it take to engage them? My next step is to pick up a vacuum pump and see if I can engage them with it.
