Replacing a wiper arm spring may seem like a small task, but it plays a crucial role in maintaining your vehicle’s windshield wipers. These springs ensure that the wiper arms are properly tensioned, allowing the wipers to effectively clear the windshield for better visibility, especially during rain or snow. Over time, wiper arm springs can wear out or break, causing the wipers to malfunction. If you're wondering how to replace a wiper arm spring, you’ve come to the right place. This article will guide you through the process, explaining the tools needed, the steps involved, and important considerations.
What is a Wiper Arm Spring?
Before we dive into the replacement process, let’s first understand what a wiper arm spring is. The wiper arm spring, often referred to as a Windshield Wiper Arm Spring, is a crucial component of the windshield wiper system. It provides the necessary tension to press the wiper blades against the windshield, ensuring effective wiping. Without the right tension, wipers may either drag or leave streaks, hindering visibility.
There are several types of wiper arm springs, including windscreen wiper arm springs, Windshield Wiper Arm Spring pressure springs, and wiper spring tension components. While most springs serve the same general function, it’s important to use the correct spring for your vehicle.
Signs You Need to Replace the Wiper Arm Spring
There are a few telltale signs that your wiper arm spring might need replacement:
Wipers are Skipping: If the wipers are skipping or not making proper contact with the windshield, the spring may be worn out, losing its tension.
Wipers Are Not Operating Smoothly: Jerky or uneven movement of the wiper arms is another sign that the windshield wiper spring tension is too weak.
No Pressure: If you notice that the wiper blades are not pressing firmly against the windshield, it may indicate a malfunctioning spring.
Wiper Arm Failure: In some cases, the dorman wiper arm spring assist may wear out or break, preventing the wiper arm from functioning properly.
Tools and Materials Needed
Before replacing the wiper arm spring, make sure you have the following tools:
Replacement Wiper Arm Spring: Purchase the correct windshield wiper arm spring replacement for your vehicle. Some brands to consider include Dorman wiper arm spring assist and other aftermarket or OEM parts.
Flathead Screwdriver: For prying off the wiper arm cover or for any necessary adjustments.
Socket Wrench: Used for removing the wiper arm bolts.
Wiper Arm Puller: This tool helps remove the wiper arm from the spindle without damaging the assembly.
Lubricant: Some lubricant may be needed to ease the process of replacing the spring and prevent future corrosion.
Replacement Wiper Blades: It’s always a good idea to replace the wiper blades when replacing the spring for optimal performance.
Step-by-Step Guide to Replacing the Wiper Arm Spring
1. Lift the Wiper Arms
First, raise the wiper arms from the windshield. Most wiper arms can be lifted away from the windshield easily, but some might require you to pull them away from the glass at a 45-degree angle. This gives you enough space to work on the wiper assembly.
2. Remove the Wiper Arm
The next step is to remove the wiper arm itself. Use a socket wrench to remove the nut that holds the wiper arm to the spindle. Some vehicles may have a cover or cap that needs to be pried off before you can access the nut.
Once the nut is removed, gently pull the wiper arm off the spindle. If the arm is stuck, use a wiper arm puller to safely remove it. Be careful not to damage the windshield or the wiper arm during this process.
3. Locate the Wiper Arm Spring
With the wiper arm removed, you will now see the wiper arm spring. It’s usually located at the base of the arm, and it applies pressure to keep the wiper blade against the windshield.
Check if the spring is damaged, rusty, or broken. If you notice any of these issues, it's time to replace the spring.
4. Remove the Old Wiper Arm Spring
To remove the old spring, you may need to use a flathead screwdriver to pry it off. In some cases, the spring may be attached with clips or additional fasteners, so check for these and remove them carefully.
5. Install the New Wiper Arm Spring
Once the old spring is removed, install the new windscreen wiper arm spring. Ensure it fits securely and is placed correctly. The spring should apply the right amount of tension on the wiper arm to ensure smooth and effective wiper movement.
If you are using a Dorman wiper arm spring assist or another type of spring, ensure it matches the specifications required for your vehicle model.
6. Reassemble the Wiper Arm
After the new spring is in place, carefully reinstall the wiper arm. Line it up with the spindle and secure it in place with the nut you previously removed.
7. Test the Wiper System
Before driving, turn on the wipers to check that the new spring is working as expected. The wipers should move smoothly, pressing firmly against the windshield. Adjust the tension if necessary.
8. Replace Wiper Blades (Optional)
While you have the wiper arms off, it's a good idea to replace the wiper blades. This ensures that the entire system is functioning at peak performance.
Tips for Maintaining Your Wiper Arm Spring
Regularly Check Tension: Periodically check the wiper arm spring tension to ensure it remains at the correct level.
Lubricate the Wiper Arm Mechanism: Use a lubricant to prevent rust and corrosion on the wiper arm assembly, which can prolong the life of the spring and other components.
Replace Blades Regularly: Even if the spring is in good condition, replacing your wiper blades regularly ensures proper performance.
Use OEM Parts: When replacing the spring, it’s often best to use OEM or high-quality aftermarket parts that are compatible with your vehicle.
