Reasons to Adjust and Align Wiper Arms

Your wiper arms may need to be adjusted and aligned from time to time. It is not unusual for wiper blades to get put in an improper position over time. They might become twisted or they may pull away from the windshield. When this happens, it will prevent the wiper blades from working properly.

You should be able to align the blades to fix these problems. Some people make the mistake of thinking that their wiper blades have gone bad when they are really just dealing with a misaligned wiper arm. It is actually fairly easy to align things properly, so learning about this is going to be worth your while.

You will also be able to prevent problems such as chattering when you align your wiper arms properly. Chattering can be very annoying and it will cause you headaches while you are on the road. Fixing the alignment will keep the wiper blades from chattering against the windshield and you will have a better overall experience. Now that you know why you want to align your wiper arms, it is time to dig into what needs to be done.

Necessary Tools

Before getting started, you will want to gather a few tools that will be necessary for these tasks. All of the necessary tools are common and you should have them around your house somewhere. Even if you don’t, you will likely have a neighbor or a family member who has access to these tools. Once you gather the tools listed below, you will be ready to begin.

  • Socket set
  • Ratchet set
  • Pliers
  • Flathead screwdriver

Adjusting the Park Position

The first thing that you need to do when preparing to adjust the park position is turn your ignition to accessory mode. You also need to make sure that you have your wiper switch off. Once this is done, you can turn your ignition off and take the keys out. Your wiper motor should now be in the parked position.

It is possible that your wiper arms may not be perfectly aligned, but don’t worry about this for now. Go ahead and focus on the base of the wiper arms. To gain access, it might be necessary to open the hood of your car. You might need to take the cowling off as well so that you can get to the base.

With this done, you need to find the retaining nut. It should be located at the bottom of your wiper arm. If it has a protective plastic cap covering it, then this will need to be removed. You can pull it off using your flathead screwdriver and it should not give you any problems.

Grab your ratchet set and your socket set so that you can remove the nut. You should move the wiper arm back and forth with care. Continue pulling the base of the arm off. You may want to use your screwdriver to try to pry it off, but you want to take care not to harm the splines during this process.

Once that is done, you will need to align the wiper arm onto your splined wiper arm. Put it in the proper parked position. Go ahead and press the arm into the stud.

Your car might have a type of wiper arm stop that the arm is supposed to rest against. If this is the case, then you will want to make sure that the arm is pressed against the stop when you are pressing it into the stud. As long as you know this, it should not be a problem.

Now you need to replace the retaining nut. Once this is replaced, be sure to tighten it really good. Do the same thing for your other wiper arm if you need to.

Put your key in the ignition so that you can test things out. Go ahead and switch your wiper blades on to see if the wipers will return to the proper park position. If they do, then you have successfully completed your task. You can turn your ignition back off and be proud of completing this job without any problems.

Adjusting Wiper Blade Alignment

Adjusting the wiper blade alignment is even simpler and has fewer steps. You just need to grab your pliers and bend your wiper arms back into the right position. It is actually good to use two sets of pliers for this job. You can hold the wiper arm in place with one set and twist with another.

You want the wiper arm to be at a right angle. It should not take long to twist the wiper arm into this position. Your pliers can be used to bend the arm toward the windshield if necessary. This is good to know if your wiper blades are not making contact with your windshield properly.

Sometimes, the blades will be really out of alignment when you are doing this. In this situation, you want to take a look at your wiper blades to examine the articulated fingers. If these fingers are not pressing the rubber part of the wiper blades against the windshield, then you’re simply going to need to buy new wiper blades. Sometimes, an alignment is not going to be able to fix your problems.

You should take this opportunity to inspect your wiper blades thoroughly. If the wiper blades are stiff, worn down, or cracked, then you should likely buy a new set. Wiper blades are fairly inexpensive and you need to replace them once every year, at the very least. Do your best to make a judgment call on the condition of your wiper blades if aligning the blades is not working for you.
