I drive a 00 civic ex coupe and recently had a sound system installed. We had to unmount the doors to drill a hole for the new wiring and now when I close the passenger door it squeaks right when it shuts. It actually sounds like the same squeak I assume my struts were doing when I drive on dry days or when I hit little bumps in the road.

what could cause that problem?

 

Check the edge of your fender where it matches up with the door... your door might be scraping the fender when you open/close it. When the door just barely scrapes the fender, it makes a squeaking sound.

 

it's not a rubbing sound, but like the same squeak on an old suspension.

 

did he lube the hinge? i use wd40 myself

 

i can open it fine without any noise, but the second it closes against the car it makes a squeaky noise. It sounds like my suspension over a bump, which is weird because it sounds exactly the same.
