this can be the seal on the front differential.
part # 1925-7296 (seal)

You can make a manual test and see is the front axle disconnect is working.
put the truck in 2WD, remove the 4*4 switch actuator, and push where the hole is located (when you remove the switch actuator) and try to move the front prop shaft. it must be locked.
else try to push a little harder and must lock.. else there is a problem probably with your front splined disconnect axle.
