I came home to find my wife with the front of her 4WD drive disconnected and her phone propped up showing the YouTube instructions. A $1400 job was replaced by her time and the cost of factory parts ($200) and 1/2 gallon of dish soap. Still going strong 110k miles later. She deferred to the $1500 mechanic rebuilding the transmission though (after the 110k miles) because she couldn't find a YouTube for that.
