Tools You'll Need:
* Wiper arm puller: This is highly recommended. Trying to pry them off without one often results in damage to the wiper arm or the wiper mechanism on the spindle. You can find these at most auto parts stores.
* Penetrating oil (like PB Blaster): Spray this liberally on the wiper arm nut (if applicable) and the connection point between the arm and the spindle. Let it soak for at least 15-20 minutes.
* Wrench (likely a small socket wrench): Some YJs have a nut securing the wiper arm to the spindle. You'll need the correct size wrench to loosen it.
* Shop rags or towels: To clean up any spilled penetrating oil.
* Gloves (optional): Protect your hands from grease and oil.
Steps:
1. Preparation: Park your Jeep on a level surface and engage the parking brake. Turn off the ignition.
2. Apply Penetrating Oil: Generously spray penetrating oil onto the connection point where the wiper arm meets the spindle. Focus on getting it into any crevices. Let it sit for at least 15-20 minutes, or even longer if the arms are particularly stuck. Reapply if needed.
3. Locate the Nut (if present): Some 1988 YJs have a nut securing the wiper arm to the spindle. If yours does, locate this nut and use the appropriate wrench to carefully loosen it. Do NOT remove it completely yet. Just loosen it a bit to break the corrosion.
4. Use the Wiper Arm Puller: This is the crucial step. Following the instructions that came with your puller, carefully attach the puller to the wiper arm. The puller will usually have a claw that grips the wiper arm and a bolt that applies pressure to pull the arm off the spindle. Apply firm, even pressure. It may require significant force, but avoid using excessive force which might damage your windshield or wiper motor.
5. If No Nut and No Puller: If your Jeep doesn't have a nut and you don't have a puller (not recommended), you can try carefully using a flathead screwdriver and a mallet or rubber hammer. However, this method carries a much higher risk of damage. Use extreme caution! Place the screwdriver's blade between the wiper arm and the spindle. Tap the screwdriver handle gently with the mallet, working your way around the arm until it comes loose. This method is prone to damaging the wiper arm or spindle.
6. Remove the Wiper Arm: Once the arm is loose, carefully pull it away from the spindle.
7. Repeat: Repeat steps 2-6 for the other wiper arm.
8. Reinstallation (in reverse order): When reinstalling the wiper arms, ensure they are aligned correctly. Tighten the nut (if applicable) to the manufacturer's specifications.
Important Considerations:
* Damaged Parts: If you damage a wiper arm or spindle during removal, you may need to replace the damaged part(s).
* Professional Help: If you are uncomfortable performing this task, it's best to take your Jeep to a qualified mechanic.
By carefully following these steps and using the proper tools, you should be able to successfully remove your windshield wiper arms. Remember safety first!
