Wiper Replacement Arm for the 1998 Nissan Altima: A Comprehensive Guide

Introduction

Wiper arms are essential components of any vehicle, playing a crucial role in ensuring clear visibility during inclement weather. Over time, however, these arms can become worn, damaged, or corroded, compromising their effectiveness. In such cases, it becomes necessary to replace the wiper arms to maintain optimal functionality. This guide will provide a detailed step-by-step process for the replacement of the wiper arms on a 1998 Nissan Altima.

Step 1: Safety Precautions

Before commencing the replacement process, it is essential to take the following safety precautions:

Park the vehicle on a level surface and engage the parking brake.

Turn off the engine and allow it to cool completely.

Disconnect the negative terminal of the battery to prevent any electrical hazards.

Step 2: Tools and Materials

You will need the following tools and materials for the replacement:

New wiper arms (preferably OEM or high-quality aftermarket components)

10mm socket wrench or spanner

Flathead screwdriver

Clean rags

Multipurpose lubricant (optional)

Step 3: Location and Removal of the Wiper Arms

1. Locate the Wiper Arms: The wiper arms are attached to the base of the windshield on the driver and passenger sides.

2. Remove the Plastic Cover: Use a flathead screwdriver to gently pry off the plastic cover located at the base of each wiper arm.

3. Unscrew the Nut: Beneath the plastic cover, you will find a 10mm nut holding the wiper arm in place. Use a socket wrench or spanner to loosen and remove this nut.

4. Pull Off the Wiper Arm: Once the nut is removed, carefully pull the wiper arm straight up and off the spline shaft.

Step 4: Lubrication (Optional)

If desired, you can apply a small amount of multipurpose lubricant to the spline shaft before installing the new wiper arms. This will help reduce friction and prevent future corrosion.

Step 5: Installation of the New Wiper Arms

1. Align the New Wiper Arm: Position the new wiper arm on the spline shaft and ensure that the splines are aligned correctly.

2. Tighten the Nut: Hand-tighten the 10mm nut onto the spline shaft. Use the socket wrench or spanner to further tighten the nut, but avoid overtightening.

3. Replace the Plastic Cover: Snap the plastic cover back into place at the base of the wiper arm.

Step 6: Repeat for the Other Side

Repeat steps 3 to 5 for the wiper arm on the opposite side of the windshield.

Step 7: Reinstall the Battery Terminal

Once both wiper arms are replaced, reconnect the negative terminal of the battery.

Step 8: Test the Wiper Arms

Start the engine and operate the windshield wipers to ensure that they are functioning properly. Adjust the wiper blades as necessary to optimize visibility.

Conclusion

Replacing the wiper arms on a 1998 Nissan Altima is a relatively straightforward procedure that can be completed in under an hour with the right tools and materials. By following the steps outlined in this guide, you can restore the effectiveness of your windshield wipers and ensure clear visibility during inclement weather.
