Was out for a ride today and noticed that on my dash it showed I was still in 4 wheel drive where as the button was in the 2wd position. I tried reverse and can’t get it out.i tried locking the front diff and the light will flash but won’t lock up completely .i checked fuses and nothing is blowed.the button is working to turn the diff lock on but just doesnt lock it or take it out of 4wd .does anyone know what the problem may be? I did have a rattling noise in the front diff a couple months ago.dont know if this has anything to do with it.
