Hey guys need any help I can get. I have a 2004 fx 4 crew cab. When I turn my 4x4 **** the light comes on and I hear a clicking noise likes its engaging but only my back tires spin? Could this be a easy fix or should I take it to the dealers to get it worked on. Being a school teacher I will take any savings I can get by doing it myself thanks guys.
