Here are pictures of the slide inside the ignition housing. The tab on the left end is what sticks out of the housing and locks the steering wheel. When the ignition is turned on the slide moves right and the tab retracts into the housing. The block with the pin on the bottom that we remove in the mod is what is in the middle of the slide. The pin on the bottom keeps it from being to deep and blocking the slide when the ignition is turned on. With the ignition off the spring on the top of the block that we remove in the mod pushes the block down thus blocking the slide from retracting.
When worn the block wont ride high enough in the slide groove for the slide to go under it. The slide rails start to catch the underside of the block causing the hitch you feel when you start to have a problem until finally the block blocks the slide completely and jams the ignition.
