Why doesnt my 4 wheel drive work in my 2000 Kia sportage?
Although you have a manual shift on the transfer case the hubs lock in on vacuum. Chances are you have bad vacuum lines going to the hubs (about $150+ at a Kia dealer or $40 at your local service station). If not the lines, it will be the seals in the hubs.

NO. Engaging four wheel drive only engages the transfer case. Older four wheel drives had to have the hubs locked manually, by turning a dial on the hub itself. Newer vehicles no longer require the hubs to be manually locked.
