Hello, I am having trouble with my left front wheel not spinning in 4x4. I replaced the armature plate, checked for continuity on the wires for the coil (they get power). I am thinking now that it must be the magnetic coil. I bought a repair manual for it, and it says nothing on replacing the magnetic coil. I am curious how difficult it is to do this, if I should try it myself, take it to the dealer to have done (if so what kind of repair bill i'm looking at), or buy a used strut off Ebay. Thank you.
