Tools You'll Need:
* Small punch: A precision punch, slightly smaller than the roll pin diameter, is ideal. Avoid using anything too large or dull.
* Hammer: A small ball-peen hammer or a dead blow hammer works best. Avoid using a heavy sledgehammer.
* Needle-nose pliers: Useful for grabbing and removing the roll pin once it's started.
* Ignition switch lock cylinder removal tool (optional but highly recommended): This tool simplifies the process and reduces the risk of damage. It usually involves a special key or pin to push the cylinder out.
* Penetrating oil (like PB Blaster): Helpful to loosen any rust or corrosion.
Procedure:
1. Preparation: Disconnect the negative battery cable to prevent electrical shorts. Apply penetrating oil to the roll pins and the ignition switch cylinder. Let it soak for at least 15-20 minutes.
2. Access: You'll need to access the ignition switch cylinder from behind the steering column. This usually requires removing the steering column shroud (plastic cover) and potentially some other trim pieces. Consult a repair manual for your specific vehicle to ensure you know exactly which parts to remove.
3. Locate the Roll Pins: There are typically two roll pins that secure the ignition switch cylinder in place. Locate them carefully.
4. Punching Out the Roll Pins: This is the most delicate part:
* Positioning the Punch: Place the punch against the end of the roll pin, centered as precisely as possible.
* Gentle Tapping: Use light, controlled taps with the hammer to start the roll pin moving. Avoid forceful blows, as this can damage the steering column or bend the roll pin.
* Working the Roll Pin Out: As the roll pin starts to move, keep tapping gently and using the needle-nose pliers to carefully guide it out of the hole. Work slowly and patiently.
* Repeat: Repeat this process for the second roll pin.
5. Removing the Ignition Switch Cylinder: Once both roll pins are removed, the ignition switch cylinder should slide out (sometimes it can be stubborn, requiring a little wiggling or leverage, but never force it). If you have a specialized removal tool, use it now according to its instructions.
6. Installation (Reverse Order): Install the new ignition switch cylinder, making sure it's seated correctly. Then, carefully install the roll pins using the reverse process, ensuring they are fully seated.
7. Reassembly: Reinstall all removed trim pieces and the steering column shroud. Reconnect the negative battery cable.
8. Testing: Test the new ignition switch cylinder to ensure proper operation.
Important Considerations:
* Repair Manual: A repair manual specific to your 1995 Mercury Tracer is highly recommended. It will provide detailed diagrams and instructions, greatly reducing the risk of damage.
* Patience: This process requires patience and careful attention to detail. Rushing can easily lead to damage.
* Professional Help: If you are uncomfortable performing this repair yourself, consider taking your vehicle to a qualified mechanic. Replacing an ignition switch cylinder is a relatively simple repair, but it's essential to do it correctly to avoid potential security or driving issues.
By following these steps carefully, you should be able to successfully remove the roll pins and replace your ignition switch lock cylinder. Remember safety first!
