Transfer case actuator motor

[Skier1]

Wife was driving the car today and rang me to tell me 3 warning lights had come on and car making a loud clicking sound when she turned it off. I done a bit of reading in the book in the car and then got her to start the car and turn it off.Traced the clicking noise back to the actuator.I then remembered about reading about this on the forum,I am just about to pull it off and turn the gear.I have also just ordered a new gear from odometer gears hopefully will arrive before Xmas and I will fit before our annual holiday.This forum has saved me $$$$ with the tips I have read about repairs.I like to do everything myself and hopefully will never have to visit the dealer.Sounds like I may need to get the adaption values reset.Can this only be done by the dealer ? what tooling etc is required to do it yourself ??
