  1. 99-03 7.3 Drivetrain Problems
    I’ve got a manual 2000 F350 and I’ve been trying to get the 4x4 to work for a couple days now. When I bought it the shift motor was missing and when I pulled the switch during diagnostic checks I noticed the locking tab had been shaved down, so it looks like the last guy was wrestling with it is...
  2. General 6.4L Discussion
    So I've searched for days for an answer but can't find one anywhere. I've been without a vacuum system for a couple of years. I decided to replumb all the lines from the hubs to the pump with blue silicone lines with appropriate fittings. The T at the degas bottle goes down the driver's side...
  3. 99-03 7.3L Powerstroke Problems
    Truck is a 2003 F350 4x4 SRW CCSB 7.3L I understand my vacuum lines are irrelevant. It's my transfer case, the t-case motor isn't actuating the 4wd, and I'm also not getting any dash lights. (Dash lights do come on when starting truck) Now I have taken some action on trying to get this thing...
  4. 6.0L Electronics Discussion
    Ok, Quick question. My 4x4 indicator light is and has been illuminated as long I have owned the truck (3 months). It is not really in 4x4. I took it to the stealership and had them perform a diagnostic. They said the Tech tracked the problem to a pinched wire somewhere in the dash. So its...
  5. 6.0 Drivetrain problems
    Ok so I just bought a 2004 F-250 6.0 with ESOF 4WD. The 4x4 indicator light is on and won't turn off. I have replaced the Pulse Vacuum solenoid, replace vacuum hoses to hubs and ensured that the vacuum pump is working. With the key in the on position I can hear the transfer case motor shifting...
  6. 99-03 7.3L Powerstroke Problems
    I have a 2002 f350 7.3 and today I noticed that when starting up my truck the 4x4 light on the dash did not light up. I also noticed that when turning the ESOF the relays would not click in and the dash light would not come on. Before this happened this morning I had trouble with the radio...
  7. 99-03 7.3 Drivetrain Problems
    So my 4x4 isnt working. 02, ESOF, warn manual hubs installed and all metal. I bought the truck with the hubs already in. SO, i flip the switch and the 4x4 light comes on and i am theoretically in 4x4 and it falls on its face when I let off the fuel like it should. Yet, i get stuck and i might...
  8. 99-03 7.3L Powerstroke Problems
    Just recently had my heater core go out of my 4wd 2002 F350 PSD. Equipped with Auto tranny, ESOF and electric everything Lariat package. When the heater core went, it smoked my GEM module, made my 4x4 and 4lo lights come on in the instrument panel, also made my backup alarm "off" light come...

I have the manual lock hubs and the "circular"swith to go from 2WD 4HI and 4LOW, is that ESOF or do I have to get out and manually lock to...
