I could have sworn that the only reason our doors sag when you put the front/ rear end on jackstands is because the door hinge itself has gotten too old? My driver's side door assembly was replaced 2 years ago due to a T-Bone accident that crumpled the shell. Well i definately remember my passenger door needing to be pushed up to latch in, but my driver side i swear i just close it normally and thats because it has new hinges/ latches and whatever parts are in there.
