I have a 2008 F350 and my automatic hubs won't work, also when I turn the AC on there is heat coming out of one side of the vents. I am assuming this is a vacuum leak somewhere but my vacuum pump doesn't run steady? I thought if there is a vacuum leak then your pump should run steady? The 4X4 works fine by locking in the hubs
View 7 Replies2008 F350 hubs wont stay locked in when in auto position. everything stays locked while in manual and 4x4 works fine, but in auto the hubs wont stay locked while spinning. I was trying to find the problem when i noticed that one hub stays locked all the time and the other locks and unlocks as it should but it wont stay locked while spinning. My question is do I have two bad hubs or is their a leak that wont let the hub stay locked? Also on the hub that wont unlock is this a leak problem as well or a internal problem?
View 5 RepliesI just purchased an F-350 with manual locking hubs. I am unsure if I can keep these locked in for part time four wheel driving or I need to unlock them each time I go back to two wheel drive?
View 6 RepliesWell long story short, I had the the factory hubs in my 04 f-350 and I was driving down the road and it started making this horrible popping noise. So I pulled over and couldn't find anything and just curiosity locked in the hubs and all was fine. Made me think my hubs were bad, so I went and bought the warren premium hubs, installed them. Went for a drive and still the same noise is there when they are in free spin. But once they are locked in its fine. What this could be? Wheel bearings?

View 8 RepliesI drove my pickup on mostly dry pavement the other day with it in 4WD and the hubs locked. I got a bit of shimmy/vibration which quit after about a mile. When I got back on ice, the 4WD wasn't working. I assumed the transfer case or locking hubs had failed. Today I got it up on jack stands, put it in 4WD, and locked the hubs. Everything seems fine. What might have happened when I couldn't get 4WD to function.
View 2 RepliesI have a 2005 f350 with the power stroke I went through the hole vacuum system all new hubs, seals, vacuum actuator and fixed it all now I'm having the reverse problems everyone has my hubs are locked all the time as soon as I plug in the vacuum actuator the transfer case is still in 2wd and will switch 4x4 and work and disengage but the hubs are always in unless I unplug the actuator ...
View 6 RepliesI was using 4x4 High the other day and it was working just fine. Now today, I was at my first parking lot to plow and used the ESOF to shift into 4x4 High and it did not engage with the hubs being in auto mode. The lights on the dash show up indicating that I am, but I am still in 2wd.
If I manually lock the hubs, it engages 4wd high. I tried the same thing using the ESOF to switch over to 4x4 low and it does NOT engage either.
I also noticed that heater blower was switching over to full defrost even though I had it set on the floor setting (manual heat climate *****).
Does this sound like a vacuum leak? I haven't had a chance to test the lines yet. Btw, this is my second work truck and not the one listed in my signature below. It's a 2006 f-350 6.0 xlt.
I just bout a F350 V10, 2008. All is great except for the clearance lights. I took advice from this site....checked the bulbs....replaced the fuse....still doesn't work. There is no damage on this truck. Is there something special I need to do to turn these lights on?
View 2 RepliesMy 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 1 RepliesI have a 2008 F350 Super Duty Regular cab long bed 4X4 I have no cargo light and no third Brake light, checked and even replaced bulbs. Still have no lights up top, what to check or how to fix this? Can I tie the cargo light into the dome light inside without screwing something up? I can't understand why they stopped hooking the cargo light to the dome light but this one seems to be wired separate. Would love to get these lights working again. When I bough t the truck the cargo light didn't work and I thought maybe the bulbs were burnt out, I never checked the brake light I tried to get the cargo light working and that's when I found out the brake light didn't work either.
View 3 RepliesI just bought an '08 F350 Super Duty CC. When I bought it, the previous owner gave a me card with the code on it. So I tried to reprogram the keyless keypad to a new code that I can remember, no luck at all. Followed all the steps on how to reprogram it like a hundred times and still won't reprogram. So I've noticed that none of the lights light up except 7*8, none of the other buttons won't light up.
Could the keyless keypad be going south? Maybe the contacts in the keyless keypad are gummed up or a relay? Need to get this feature to work cause I sure would use it a lot. Also how do I remove the interior door trim to get to the keyless keypad? The door panel has electric locks, electric window, power mirrors, telescoping rear view mirrors, memory seating buttons and speaker pillar.
My 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 Replies2001 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.
View 6 RepliesI 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.
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...
I noticed that my 4WD is only working now when I manually lock the hubs in (they have that options!), and the air blows out the defroster when I shift, so it looks like I have a vacuum leak. Where are the typical leak points on a 2006 F250? What's the best way to confirm a leak (other than just replacing all of the hose)?

View 1 RepliesOn my 05 350, I noticed the other day that my 4wd wasn't working, when I needed it of course. I quick test this morning and I discovered my PS hub is not locking in. I've read a lot of posts about it being the opposite, the auto portion causing a problem. In my case, it won't lock in in auto or manually turning. I can lock it in, spin the wheel and the axle shaft isn't turning. The pressure is the same as the other side, not too loose or too stiff. Can I pull the hub assembly off and rebuild it? I watched a video about that, but not sure on how my issue would allow me to work on it.
View 4 RepliesThe 4wd on my 2000 f350 has just stopped working? I have used it a few times since getting it a few months ago and then last night I was going to play paintball in the woods and the 4wd would not engage? when i put it in 4wd it would act like the truck is in neutral and then it lurched forward? The front hubs have the option on them to turn, but I never had to turn them before and they do not move when I tried to? What could be causing the 4wd not to function?
