OK, so the front axle was out of oil or was it the transfer case?

transfer case
Expert:  GM Tech (Cam) replied 7 years ago.
Did you just fill it up with fluid or did you fix the leak?
Customer: replied 7 years ago.

I did not see ant leakage. Was just when I took it in for service I was told it was very low/


Expert:  GM Tech (Cam) replied 7 years ago.

Ok, these transfer cases are bad for the pump clip wearing out and the ear of the pump wearing through the case. Below is a picture that shows the possible location of the hole.

There is oil in the transfer case now but what needs to be done to get the four wheel diver working
Expert:  GM Tech (Cam) replied 7 years ago.
If the oil got too low, then there may be something binding in the transfer case and not allowing it to shift. To start with, check the front diff to see if it is engaging. Spin the actuator out and see if it extends. IF not, then you may need an actuator. If so, push a screw driver in the hole to see if the shift fork moves.
