How hard is it to line a door back up when you put it back on? The reason I ask is that I found the vac leak in my locking system, someone had taken the door off in the past (drivers door) and didn't get the rubber accordian thing back over the lines (between the door and the rest of the car). Theres a hole rubbed in the line for unlocking the other doors so it leaks anytime the doors are unlocked. Anyway, I can't get to the leak to fix it without removing the door and was wondering if they are hard to get realigned so they shut right....... if they are I may want to live without the locks working for a while longer.

Also, anything I should know before removing the door?
