The root of the problem for these GM truck doors seems to be in the hinges. The hinge pin wears, causing the door to sag slightly. The sagging door rests more heavily on the striker and requires increasing force to open. After while - bingo - you will break one or both of the handles jerking the door open! A body shop wanted $300 to put in new door hinge bushings.
