I bought this vehicle a couple month back and 4x4 worked as supposed to according to owner manual. Now without warning 4Hi only goes in if stopped and in neutral just like if you would if you'd shift into 4lo. Once in 4Hi ,the indicator lamps aren't lit, even tho it's fully engaged. The indicator lamps work when they self check when you first turn ign. on. In addition 4lo has only 1st gear now instead of 3. Anybody ever had this happen? I should prob mention this is a shift on the fly 4x4 where you can shift into 4Hi at "any" speed according to the manual.
