i'm stumped on this. i put in a new front diff for a regear a few months ago. it was good and working before it was put into my truck so i know nothing is broke. but now my 4wd light is always on even though it still works as normal - 2wd and 4wd hi and low
i was just ignoring it for the last few months but i forgot about it being on 2 mornings in a row this week and decided it may be time to fix it.
