On my dash the 4X4 light comes on even though it is not engaged at all. I will wiggle the shifter around and the light will go off, but as soon as I go over a little bump it will light up again. The shifter has play and has a vibration and irritating rattle as if gears are making very slight contact. Are there any typical components that wear out that are to be replaced (like a seat/collar) to make it an easy fix or is there more to it? If anyone has a tutorial that would be awesome as well. Thanks!
