Tools You'll Likely Need:
* Wiper arm puller: This specialized tool is highly recommended to avoid damaging the wiper arm or the shaft. Trying to pry them off with screwdrivers or other tools often results in scratches or broken parts.
* Socket wrench (possibly): Some vehicles require a socket to hold the nut on the wiper arm shaft while you use the puller. Check your vehicle; it might not have a nut.
* Penetrating oil (like PB Blaster): This can help loosen the wiper arm if it's stuck. Spray it around the base of the arm and let it sit for a while before attempting removal.
* Gloves: To protect your hands.
* Shop towels or rags: To clean up any mess.
Steps:
1. Disconnect the battery: This is a crucial safety precaution to prevent accidental short circuits.
2. Locate the wiper arm nut (if applicable): Some vehicles have a nut securing the wiper arm to the shaft. If yours does, locate and carefully loosen it using the appropriate socket wrench. Don't remove it completely yet.
3. Position the wiper arm: Lift the wiper arm to a position roughly perpendicular to the windshield. This gives you the best leverage.
4. Apply penetrating oil: Spray penetrating oil generously around the base of the wiper arm where it connects to the shaft. Allow it to soak in for 10-15 minutes.
5. Use the wiper arm puller: Place the puller's claws around the wiper arm base, ensuring a secure grip. If there's a nut, use your socket wrench to hold it in place while you tighten the puller. Slowly and steadily tighten the puller, applying pressure to separate the wiper arm from the shaft. It may require some force, but avoid excessive force to prevent damage.
6. Remove the wiper arm: Once the arm is loose, carefully pull it off the shaft.
7. Repeat: Repeat steps 3-6 for the other wiper arm.
8. Reconnect the battery: Once both wiper arms are removed, reconnect the battery.
Important Considerations:
* Spline Damage: The splines on the wiper motor shaft are delicate. If you damage them, you'll likely need a new wiper motor. This is why a puller is so important.
* Stuck Arms: If the arms are extremely stubborn, you may need to apply more penetrating oil and let it sit longer. Avoid using excessive force, as it could break the arm or damage the shaft.
* Repair Manual: Consulting a repair manual specific to your 2006 Chrysler Town & Country is highly recommended. This will provide diagrams and step-by-step instructions tailored to your vehicle, minimizing the risk of damage.
If you're uncomfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic. Replacing wiper arms isn't overly difficult, but improper technique can lead to expensive repairs.
