2001 Kia Sportage 4wd

put the little booger on blocks and start it. put the transfer case in gear. if the light on the left side of the dash comes on, put in gear and look under the front and see if the cv axles that stick into the wheels are turning. if so, you have bad hubs. if not, the t/case is not engaging. transfer case issues are best left to experts in trannyshop. hubs are easy to change out. good luck
