I loosened the 3 bolts on the pillar ends of each of the hinges. The door won't slide up (or down). I have put a floor jack under the door to gently coax it upward, but it won't budge.
Has corrosion I can't see locked it into place.
Thanks!!!!

I hate to say this but what's the beltline?

Repeat as necessary. | | | | | Joined: Mar 2010 Posts: 10,301 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,301 | Lets back up a few steps before we proceed further.
Did you rebuild the hinges? If not, there is a good chance that worn hinge pins are causing door sag which cannot be compensated for at the hinge pillar.
Worn hinge pins are the #1 cause of beat up door latches and poorly fitted doors.

I'm slow at fixing things (and replying!). Would worn hinge pins cause the hinge to not slide up or down when the 6 pillar bolts are loosened? Seems the hinge should still slide but maybe not enough to compensate for a worn hinge pin.
Thanks again!!

I had the same issue you are having after replacing the lower hinge pillar which has the lower hinge pocket within it. I measured wrong when I cut the old one off and welded the new one in which would not allow movement of the door up or down.
