It is possible and almost easy to repair sagging Mkl Mini door hinges with this pin and bush kit. You don't even have to remove the hinges from the car. Once you have removed the original hinge pin you simply drill a hole in the front hinge half, push in the bush which is approx 7.9mm(5/16")outside diameter and reassemble with the new pin (sometimes you find that job has been done before, so you'll only have to push out the old bush.) One bush (37H3043) and one pin (37H3044) per hinge, 2 each per door, 4 each per car.
