4 wheel drive not engaging when put in gear. Shouldnt all 4 wheels be spinning?

Either the fuse for the front hub actuator has blown or the actuator is bad.
Not a terrible job to replace the actuator, but they aren't cheap, so check all fuses and make sure they aren't blown.

Here is a how to video on the actuator replacement.
