Angry ESOF Shift motor

After spending a number of hours diagnosing why my 2004 F350 would not go into 4WD I traced it down to the shift motor on the transfer case. THe motor was making a noise so I assumed it was doing its job. After going out and getting a Mongoose J2534 cable and scanXL to read the codes and following the diagnostics from Fords shop manual I came back to the ESOF shift motor. I pulled it out last night and opened it up. The gearbox was just destroyed. Missing teeth and filings everywhere. I put a wrench on the shifter shaft and was able to shift in and out of 4WD. The manual stated less then 35lbs-ft of torque should be required. I will be going out after work tonight and getting a set of crowsfeet for my torque wrench to confirm torque required. I have one coming but they are $800can list. I was able to get mine for just under $600 but holy $H!T thats expensive for what it is.


I am writing to find out how many others have had problems with this beast. And of those of you who have, do you know what caused it to die? When I get the new one installed I will post pictures of the inside of the dead one.
