Hello, I have a 2000 cherokee sport. the lock cylinder wore out so had to replace. It was one nightmare after another. First couldnt turn key to on postion to remoe so had to drill out. Drill bit broke inside, so had to drill whole cylinder out. Anyways, upon removing cylinder some other pieces fell out. A plastic retainer a spring and some metal pieces. Just wonder if anyone had a shop manual or something with a picturenthat showed correct order to put stuff back in. With the awesomness of microsoft i attempted to draw parts Thanks
