adjusting door latches, is there a trick to it?

[pow3rslave]

for a while my drivers door seems to have had needed a bit of a throw to get it to shut and it just makes the car looks like a ghetto ride.
i had a crack at adjusting the catch with a torx head but it always seems to foul, even when it doesn't scrape the receiving bit on the door, it still doesn't close smoothly. the door doesn't have any up/down movement when its open so i don't think it's the pins. what else should i check for?

also the passenger side has a slight bit of force needed, but nothing i'm concerned with. it's just the drivers side.

does it make a cracking sound as it closes a point?

there's a feeling when the catch scrapes the top or bottom of the receiving bit, apart from that the only noise is a bit of a squeek of the sealing rubber at the front near the pins

Did you get a solution to this?
