No 4x4 on my 99' Z71
 

Ok this could've been asked somewhere in here already but I've got a 99' silverado 1/2 ton 4x4, I've replaced the 4x4 actuator in the front diff and the switch inside the cab. It now makes the noise like it's locking in but I still don't get 4x4. The auto 4x4 will work when I go to use the and the transfer case goes into low 4x4 when I hit it button but I don't get any front axel out of it. Anyone have any suggestions?

The wiring going from the transfer case to the front axle didn't get bit by the front drive shaft did it? I had a wiring problem from that on one once.
