That's a great video...Thank you for posting. I was having a problem the other day with my '14 EL LTD making that light grinding noise and not locking in. I have an extended warranty so it will get fixed (dealer wanted me to drop it off for who knows how long and it's my only work vehicle these days), but on my time now that I know what's going on. It was 15 below zero when it froze up on me, now it seems to be OK, (but mostly in 2wd)?? Still going in when my schedule allows. I really like knowing what's happening before handing it over. I'd do it myself if off warranty.
Thanks again...
