Your windshield wipers act as keys to your safety when driving. Imagine how they clear your view from any obstruction and you can be sure you can rely on them during the toughest situations. What if something goes wrong with the Porsche windshield wiper arm? What should you do about it? Of course, you need to learn how to change it right away. The procedures to follow will depend on which type of wiper arm you have.
Changing Clip-on Wiper Arms
Clip-on wiper arms have a small tab at its base. When you are replacing such type of arm for your windshield wipers, you will need a flat-head screwdriver. Before changing the arms, you should turn on your wipers up until it reaches mid-way of the windshield. Mark the location using wax crayon then you can proceed to inspecting its base. Remove the flange or slide lock attached to it. You can actually remove it using your fingers but when it is already rusty, you will need a flat-head screwdriver to help you with. From there, you can remove the wiper arm.
Changing Push-On Wiper Arms
These are arms that are pushed onto the arm post of the wiper. When changing such type of wiper arm, you also need to do the same thing as when you turned on the wiper then marked the location of the wipers using wax crayon. Look for the hinge located at that point where the wiper arm is connected to the wiper. Once you lift the wiper arm, you must insert a metal object through the hole found in the wiper arm. From there, you can just let go of the wiper arm.
Changing Bolt-On Wiper Arms
Bolt-on wiper arms are types of wiper arms that are connected to the wiper post through a bolt or nut. You need to remove the nut once you have located it. Do the same thing that you did with the other two types of wiper arms. From there, you can mark the location using a wax crayon. Make sure you have removed the plastic cover found over the nut. You can twist the cover off too. In case that technique won't do the trick, you will need a flat-head screwdriver to pry the cover off.
You must make sure you will select the appropriate socket size for your wiper's nut. Loosen the nut once you have set the ratchet to counter-clockwise. Make sure your other hand is holding the wiper arm in order to prevent damage that can affect the blade shaft and the wiper linkage. When you have removed the nut, you can easily remove the wiper arm.
Installing the New Windshield Wiper Arm
Make sure you are using the same type of wiper arm as the one that you have removed from the wiper. Using either a wire brush or steel wool, proceed to clean the wiper arm post. You must also do the same over ridges on the wiper blade shaft. Lubricate the wiper blade post then install the replacement arm. You simply have to work in a reverse manner as when you have removed the old wiper arm.
