[QUOTE="Boosted6.4, post: 894072, member: 12754"] Not sure if this is the right area or not, if not could a mod please move? Truck is a 2008 F350, with just the basic stuff, Tune, Intake, Exhaust. Lately the truck will not engage 4WD, it is not the hubs because there is no light coming on indicating the transfer case has shifted and locking them in manual doesn't change a thing. My problem is the transfer case not shifting. I have checked the switch with a multimeter for resistance and it all checks out. Checked all fuses related to the 4x4 system, along with both relays (Hi to Low, and Low to HI) With the key on engine off, I can turn the switch to 4HI and I hear the shift motor make noise on and off. It will hum for 3 seconds, stop, then hum again, it does this probably 3-4 times and won't shift the transfer case. If I try to shift it back to 2HI and then 4HI again, it will not try and shift again. Do I replace the shift motor? Where do I go from here? Thanks, as always, all help is appreciated! [/QUOTE]
