Triathlete-
got a little snow last nite, backed out of garage and decided to pull back in. Back wheels spun and started to slide down driveway (very slight incline).
Thought about open differential so I had family on each side checking for wheel spin, nothing for front wheels. Put in 4lo and it walked right in. Wheels on dash light up like it's working, no check light on and check light bulb works on start up
