Wiper arms are an essential part of your car's safety system, and it is important to keep them in good working condition. Over time, wiper arms can become loose or damaged, and they may need to be replaced. There are a few different ways to remove wiper arms, and the best method will depend on the type of wiper arm you have.
The first step is to identify the type of wiper arm you have. There are two main types of wiper arms: bolt-on wiper arms and bayonet wiper arms. Bolt-on wiper arms are attached to the windshield with a bolt, while bayonet wiper arms are attached with a bayonet fitting.
Why you should remove wiper arms?
Tools Required
You will need a few tools for this job:
-A set of hex keys ( or Allen wrenches)
-A flathead screwdriver
-A pair of pliers
-A can of penetrating oil(if needed)
Most wiper arm nuts are 13mm but some are a 15mm or 17mm so it is recommended to use a set of wrenches instead of a single wrench.
Techniques to Remove a Wiper Arm
Wiper arms can be removed using a variety of techniques, including using a specialized tool or a pair of pliers. If you are using a tool, insert it between the wiper arm and the windshield, then twist it to release the arm. If you are using pliers, grip the arm firmly and pull it straight up. You may need to apply some force, but be careful not to damage the windshield.
Once the wiper arm is loose, you can remove it completely by lifting it up and off the windshield. Be careful not to drop the arm, as it could damage the windshield or your vehicle.
If you are having difficulty removing the wiper arm, you can consult your vehicle's owner's manual or a qualified mechanic.
Here are some additional tips for removing wiper arms:
Remove the Nut
Locate the nut that secures the wiper arm to the wiper transmission shaft. This nut is usually located at the base of the wiper arm, where it attaches to the shaft. The nut may be covered by a plastic cap, so you may need to remove the cap to access the nut.
Use a socket wrench or a box-end wrench to loosen the nut. Turn the wrench counterclockwise to loosen the nut. Be careful not to overtighten the nut, as this can damage the wiper arm or the transmission shaft.
Once the nut is loose, you can remove the wiper arm from the shaft. Pull the wiper arm straight up to remove it. Be careful not to damage the wiper arm or the windshield when removing it.
Pull the Arm Up
If the wiper arm is not completely free, spray another dose of penetrating lubricant onto the base of the arm and try pulling up again. Spraying penetrating spray oil onto the shaft or the base of the wiper arm will help to loosen it up and make it easier to pull off.
You can also try twisting the wiper arm back and forth while pulling up on it. This may help to break the seal between the shaft and the arm and make it easier to remove.
If you are still having trouble removing the wiper arm, you may need to use a tool to help you. There are special wiper arm pullers that you can purchase that will help you to remove the arm without damaging it.
Once you have removed the wiper arm, you can now access the wiper motor and replace it if necessary.
Use a pair of pliers
If you happen to be stuck using pliers when removing old wiper blades, you can try using a pair of pliers to get the job done. This will allow you to get a better grip on the blade and pull it straight toward you. Repeat this a few times until the arm comes loose.
Be sure to hold the pliers parallel to the wiper arm during this process to avoid damaging the windshield. Pliers can be a useful tool when it comes to removing wiper arms, but it is important to be cautious and use them properly to avoid causing any damage.
Use a penetrating lubricant
If the wiper arms are still stuck, you can try using a penetrating lubricant. This will help to loosen the bolts and make them easier to remove. To use a penetrating lubricant, simply spray it onto the bolts and let it sit for a few minutes. Then, try to remove the bolts again.
If you don't have any penetrating lubricant, you can try using WD-40. WD-40 is a water-displacing lubricant that can help to loosen bolts and make them easier to remove.
If you're still having trouble removing the wiper arms, you may need to take your car to a mechanic. A mechanic will have the tools and experience to remove the wiper arms safely.
Here are some tips for using a penetrating lubricant:
- Make sure to spray the lubricant onto the bolts, not the wiper arms themselves.
- Let the lubricant sit for a few minutes before trying to remove the bolts.
- If the bolts are still stuck, you may need to apply more lubricant.
Use a pry bar
Make sure your pry bar is small enough to fit between the wiper arm and the windshield. Insert the pry bar between the two and gently pry upwards until the arm pops off.
If the wiper arm is particularly stubborn, you may need to use a penetrating oil to loosen it up. Apply the oil to the base of the arm and let it sit for a few minutes before trying to pry it off again.
Once the wiper arm is off, you can replace it with a new one. Be sure to insert the new arm in the correct position and tighten it securely.
Safety Precautions
Before attempting to remove any wiper arms, it's imperative to take the necessary safety precautions to prevent injury or damage. Before lifting the hood, park your vehicle on a flat, stable surface, engage the parking brake, and turn off the engine. Disconnect the negative terminal of the battery to prevent any electrical accidents. Allow the engine and exhaust system to cool completely to avoid burns.
Wear appropriate safety gear, including gloves, eye protection, and a mask to shield yourself from dust and debris. Locate the release mechanism for the wiper arms, which typically involves a small lever or button located near the base of the arm. Press the release and gently pull the wiper arm straight up to detach it from the windshield.
