4wd transfer casemotor

4 wd front lights flash on display but will not engage. When I spin or step on gas hard the 4wd light comes on and it will engage. Ran the test with ignition etc and could hear humming under truck. When I got under it was the motor humming. Where can I get a new one? Thanks

If you just need a motor, you can get a used one on Ebay, or look for a used one on car-part.com.

A brand new one will be expensive.

If the motor is humming, it seems that it is working, but something is not engaging. How dirty is your transfer case fluid? Maybe try changing it out and see if things start working again.
