driver side door play how to fix it?????

my driverside door is fine when its closed. It seals good and doesnt leak or stick out, the problem is when i open the door i can feel it drop like an 1/8 - 1/4 of an inch and when i pull it shut i hear and feel it move up that same distance so latch.
So i opened my door all the way and lift it up from the bottom corner and there is some play in it definatley

try tightening all the bolts on the door hinges

tighten your hinge bolts, if they are loose, then put a jack under your door and jack it up till you think it is level, and then tighten the bolts, should clear it all up :D

Probally need new door pins.
