New guy here. while trying to remove a ford expedition from a 10 ft ditch my 4wd quit working. i just put a new 4wd actuator in 3 weeks ago. the indicator light comes on and registers as engaged but nothing. there was faint grind for a second when i left the scene but nothing else except no 4wd and horrible alignment now. so i guess what i am inquiring is what should i check? the truck is new to me so not much time under hood. 94ext.cab z71 4wd auto 5.7L. I have read through numerous posts and cant find or missed valuable info any help would be greatly appreciated "The best lesson learned is the expensive one" Thanks Mike
