Ok so i have a 94 camaro. These doors are very long and heavy. So my driver side door when i open it sags... therefore doesnt like to close. It's pissing me off and making me sad. What is the best way to fix this? Thanks

but it cost like 20 bucks er sumthn like that.

and i wanted to add almost all 2 doors have this problem.

 

Replacing the hinges is the last thing you want to consider, mainy because they're welded to the doors.
Your bushings and pins are worn. Replace them with something like this kit: Door Hinge Bushings & Pins
The old ones won't fall right out though. You'll have to do a little grinding, but it'll be much easier than replacing the complete hinges.
