One of my hubs on my 04 f 250 6.0 broke so i bought warn premiums. Power gets to the front drive shaft and the light comes on but no power to the tires i cant figure it out any help would be appreciated

your / hub /hubs aren't locking when you engage them manually

you can isolate the side that has the issue or determine if it's both
by reaching into the axle and turning the shaft by the ujoint neither should spin by hand when locked

also did u unplug the vacuum hub actuator and plug the vac line to circumvent future issues?
