ESOF help needed
I have a 2007 F350. The ESOF started to act up one morning, it said I was in 4wd but I wasn't. Drove a little ways and then there was a whining sound and then a clunk, sounded like it was the transfer case, but it still drove normally. I stopped and tried to put it in 4low and it went in but wouldn't come out of 4low. I shut the truck off and started it and played with the selector and jerked between forward and reverse and it finally went into 2WD. I changed the shift motor on the transfer case same problem, no light on the selector at all and won't shift. Checked all the fuses and relays they are all good. I checked for power at the transfer case shift motor and there is none. The information I have found is very confusing as with regards to the SJB or Gem module. Does a SJB have any connection to the ESOF or only if you have Gem module. Any information would be of great help.
