Well sounds lke you may have a broken axleshaft. Did you remove the front driveshaft, on the Quadra-trac systems (All-Time 4WD) if you remove the front driveshaft you will roll whiole in park and you must use the e-brake. Alot of people remove the front driveshaft to improve mileage.

With the popping sound you are hearing I would say a broken Axleshaft, or bad CV joint.
