Understanding the Causes of Rear Windshield Wipers Squealing
Introduction to Rear Windshield Wiper Noise
Rear windshield wipers, often overlooked and underappreciated, play a crucial role in maintaining visibility and ensuring safe driving. However, when these wipers start squealing, it can be a frustrating and annoying experience for drivers. In this comprehensive guide, we will delve into the world of rear windshield wiper noise and explore the causes, consequences, and solutions to this common issue.
The Anatomy of a Rear Windshield Wiper
Before we dive into the causes of squealing, it’s essential to understand the basic components of a rear windshield wiper. A typical rear windshield wiper consists of:
- A wiper arm, which holds the wiper blade in place
- A wiper blade, responsible for cleaning the rear windshield
- A pivot point, where the wiper arm connects to the wiper blade
- A spring or tensioning mechanism, which provides the necessary force to move the wiper blade
Common Causes of Rear Windshield Wiper Squealing
The rear windshield wiper squealing can be caused by a variety of factors, including:
- Dry or worn-out wiper blades: When the wiper blades become dry, worn out, or damaged, they can create a squealing noise as they move across the windshield.
- Dirt, debris, or ice buildup: Any foreign substances on the wiper blade or windshield can cause the wiper to squeal or chatter.
- Loose or misaligned wiper arms: If the wiper arms are loose or misaligned, it can cause the wiper blade to vibrate, leading to a squealing noise.
- Incorrect wiper blade tension: If the wiper blade tension is too tight or too loose, it can cause the wiper to squeal or chatter.
The Consequences of Ignoring Rear Windshield Wiper Squealing
Ignoring the squealing rear windshield wiper can have several consequences, including:
- Reduced visibility: A squealing rear windshield wiper can reduce visibility, making it more difficult to drive safely.
- Increased wear and tear: Allowing the squealing rear windshield wiper to continue can lead to increased wear and tear on the wiper blade and other components.
- Damage to the windshield: In extreme cases, the squealing rear windshield wiper can cause damage to the windshield, leading to costly repairs.
Practical Applications and Actionable Tips
Now that we’ve covered the causes and consequences of rear windshield wiper squealing, it’s time to explore some practical applications and actionable tips to resolve this issue.

Inspecting and Replacing Rear Windshield Wiper Blades
Understanding the Causes of Squealing
Squealing rear windshield wipers can be a frustrating and annoying issue, but it’s often a sign of a deeper problem. The most common cause of squealing rear wiper blades is wear and tear on the blades themselves. As the blades age, the rubber deteriorates, causing them to lose their flexibility and create friction against the windshield.
Another common cause of squealing is the presence of debris on the wiper blades. Dirt, dust, and other contaminants can accumulate on the blades, causing them to vibrate and create a high-pitched squealing noise.
In some cases, the squealing may be caused by a misaligned wiper arm or a faulty wiper motor. If the wiper arm is not properly aligned, it can cause the blades to rub against the windshield at an angle, creating friction and noise.
Inspecting the Wiper Blades
Before attempting to replace the wiper blades, it’s essential to inspect them for signs of wear and tear. Look for cracks, cuts, and fraying on the edges of the blades. Check for any debris or dirt accumulation on the blades, and make sure they are properly seated in the wiper arm.
Here are some signs that your wiper blades may need to be replaced:
- Cracks or cuts on the blades
- Fraying or wear on the edges of the blades
- Debris or dirt accumulation on the blades
- Blades not seating properly in the wiper arm
- Blades not moving smoothly across the windshield
Replacing the Wiper Blades
Replacing the wiper blades is a relatively simple process that can be done at home with a few basic tools. Here’s a step-by-step guide:
1. Purchase a new set of wiper blades that fit your vehicle.
2. Turn off the ignition and engage the parking brake.
3. Locate the wiper arm and pull it away from the windshield.
4. Release the tab that holds the old blade in place.
5. Pull the old blade away from the wiper arm and discard it.
6. Take the new blade and insert it into the wiper arm, making sure it’s properly seated.
7. Release the tab that holds the new blade in place.
8. Put the wiper arm back in place and test the wipers to make sure they’re working properly.
