Ive looked thorough a few threads regarding 4wd problems and didnt find the solution to mine.

Is the Front Drive Shaft Supposed to freely spin while in 2wd? Mine spins while in 2wd and im not able to turn it by hand. Also when i enage 4 low yoiu here the clunk for it engaging but the front wheels dont spin but the front drive shaft does. What would cause this to happen?

The Vacuum Actuator under the battery tray is in good condition and the cable moves freely when you pull it. I disconnected the vacuume line going to the Actuator to make sure vacuume wasn't going to it causing the transfer case to be active. I aslo replaced the 4wd because it wouldnt engage and now it does
