Grim is right, the plastic piece that goes over the striker bolt is very important. While the sagging pins and bushings in the door hinges can add to the problem, the plastic door striker bushing is what causes most door problems. I actually fixed mine by slipping a slit piece of gray poly tubing (the kind used for water lines in RV's) over the still-installed door striker bolt. My doors shut with just the slightest bit of pressure.
