Ford F-Series 4x4 Problems



  • Did you check to see if you've got a vaccuum leak? If you've got a leak, the hubs won't pull in.

    Where would I check for a vaccuum leak? Do I check at the new solenoids or on the 4x4 case itself?
  • I have recently puchased a used F350 Super Duty Power Stroke Turbo Diesel and I just love it. I recently tried to use the four wheel drive with the shift on the fly switch on the dash. The light comes on but nothing. The hubs are on auto and nothing happens. I have followed all the proceedures to the letter. If I get out and turn the the hubs to lock, the on the fly feature on the dash works fine on, and off, on command. I thought it might be the shift motor on the transfer case but it's not becasue it does shift on and off. The problem is with the hubs not locking in and out automatically. I heard some rumors from different sources that ford has had some problems with this year and model. I went to the dealer and asked them what they thought, and they acted like it wasn't common, and that they haven't heard about this. I have an appointment to take it in, but I am not confident they are being truthful, and just want to keep the mechanics working for that day.They claim they will have to take the hubs apart and investigate. Yikes! They say 4to 5 hundred bux. I would like to know if anyone knows anything about this, and can share their experiance with me. Thanks guys.
  • I also have a 1999 Ford Escort purchased for my sons in Vancouver. My oldest son has mentioned to me few times it would be nice to have a keyless entry to his car installed. I thought being close to xmas I should look into this and if it doesn't cost a arm and a leg, Santa could bring him one. Does anyone know if this is possible to install it or the approximate costs to do so? Thanks.
  • After reading all the transmission problems I couldn't find any one that really had m exact problem. I own a 2001 Supercrew and few months ago it started to shutter a little when I turn, some time its worse than others but I haven't noticed anything that makes it worse or better. The shutter is only when I turn, it almost feels like Im trying to turn while Im in four wheel drive, but my 4x4 light isn't on and when I turn and switch it switch's to 4x4 and I can feel the difference, especially if I try to turn the shutter is much worse. Also once I switch into 4x4 it is hard to switch out, it has never gotten stuck in 4x4 yet usually I can get it out by stopping and switching it back and fourth.
    I just $500 on front end work at the tire shop on new control arms. The mechanic at the tire shop thinks it might have something to do with my differential but he wasn't sure. Any ideas?
  • Hi I just bought my super duty with 120000 miles and the 4 wheel drive is not working. The drivers side bangs in and out with the occasional grinding when you accelerate. I have switched the hubs on the front and it still does it only on the drivers side. I have had two mechanics look at it and both told me it was the hubs but didnt fix the problem. I think it is in the axle. It is also very difficult to get out of 4 wheel drive wich usually consists of driving backwards and forwards to coherce it. Any help would be greatly appreciated.
  • You also have to have the auto-transmission in neutral to engage the 4x4 low.
  • i bought this truck with 45,000 on it. everything worked fine. the 4x4 got a tricky when engageing. sometimes it would and other times not. now it doesnt do anything. no 4x4 or lights. suggestions'?
  • The 4wd on my1999 F250 quit working about two months ago. The problem is the GEM (Generic Electronic Module) but these are back ordered until 2011 and there is no substitute. Has anyone else out there had problems with these and, more importantly, did you come up with any solutions? I love the truck, but will need 4wd before 2011.

    2011? Ouch. I'd strongly consider trading for another truck. Doesn't have to be a new one, just one that works.

  • I know you are right, but I haven't gotten over being mad at Ford yet. It just seems like a hell of a way to treat a customer.
  • I have had the exact same thing happen, I fought it for a year, the only thing thats wrong is you have leaky front hub seals.
  • Was it the axle seals? I have the same problem.

    I have a 2005 (50K) with the same problem. I find if I do the following the 4 wheel drive engages:
    key off
    turn 4 wheel slector to 4 wheel high
    start truck
    the 4 wheel engages (light on)
    Wish I knew what the problem is. I would like to fix it.
  • With my 1999 F350 the light came when I switched to 4/Wheel Drive, but the HUBS did not lock. When I manually locked the hubs the 4/Wheel drive worked if this is how yours reacts then follow the info below. The auto hubs lock up by vacuum, with my F350 all vacuum lines did not have any leak but the HUB Seals did. You should check all vacuum lines and the pump first them if no leaks are found check the hubs.
  • i have had this same problem in my 2000 f 350, i had my mechaninc take the hubs apart and free them up and lube them as at first the manual turning of the hubs was very hard, this made manual locking easy but did not fix the auto problem. I have checked out the vacum including installing a new vacum solenoid on the passenger fende rand all is well with that. Now i have been told that all i can do is buy new hubs which are expensive. Could you please relate to me what exactly i need to look for or do to my hubs to fix a vacum leak in them?

    2001 350 diesel 7.3 liter HELP! ford dealer says my 4x4 locked up and the calipers burnt the hubs. A bit technical for me. I think they are scamming me out of $1100.00 I know i can get it done cheaper but how do i really know that is the only 80k miles Thanks

    Hey Guys...My son has an '03, F-250 & I have an '05 F-350 both have similar problems as the topic. My 4X4 wouldn't slip in with the interior switch. The shop replaced my vac pump (rt fender) without checking anything...that did nothing. They said that the pump goes out frequently. Then they started checking and told me that it is the gem module. Now I'm hearing hubs... My son didn't have any problems until they worked on the heads. Now he has had the vacuum pump replaced. Revolving cash register. Neither of our problems have been fixed, BUT, I'm thinking that if fORD's better idea engineers continue with these kind of issues... I'm looking for a '55 2 wheel drive. Call me a FROG!!!

    I had a simular problems on my 2004 f250 diesel and all it was that the vacuum line that control the hubs had a hole in it. The dealer also tried to repair the pump but I said no and found the hole. The vacuum lines run under the engine to each hub.

    '03 5.4 F150 4x4 At about 30k miles lost the front part of the 4 wheel drive. Inside the front pumpkin there is an unbelieveably cheap potmetal-appearing yoke for sliding the splined gear that engages the front half shafts. Just over $400 at a trusted independant transmission shop. I was stunned how cheaply made this little part was-I can see the bean-counters cheaping up on a door handle or something easy to get at, but not something like that! :(
