Should I replace whole wiper blade or just rubber?

When it comes to wiper blades, there are two main components – the rubber squeegee and the metal or plastic blade frame. The squeegee is the part that actually contacts the windshield and cleans off water, snow and debris. Over time, the edge of the squeegee can get worn down from use and exposure to the elements, reducing its effectiveness at clearing your view. This brings up the common question – when your wipers are performing poorly, should you replace just the rubber squeegee inserts or the whole wiper blade assembly? Here’s a look at the pros and cons of each option:

Just Replace the Rubber

Replacing only the rubber squeegee inserts is the more affordable option. Complete wiper blade assemblies can cost $10-20 each, while replacement rubber squeegees typically run $3-8. Here are some benefits to just swapping the rubber:

– Less expensive upfront cost. If money is tight, replacing only the squeegee rubber allows you to get your wipers working well again for minimal investment.

– Wastes less material. If the wiper frame and connections are all still functional, throwing it away just to replace the whole unit creates unnecessary waste.

– Quick and easy. Sliding new squeegee inserts into your existing wiper blade takes just a few seconds once you know how they detach from the frame.

However, there are some downsides to keep in mind with this approach:

– May not fully restore performance. If your wiper frames are very old, the spring tension that holds the blade against the windshield may be compromised. Just replacing the squeegees won’t fix that loss of pressure.

– Could be a temporary fix. Rubber squeegees deteriorate over time. If your wiper blades are already a few years old, the replacement inserts may only last 6-12 months before needing to be swapped out again.

– Inserts may no longer be available. This tends to be more common with older or less popular wiper blade models. If you can’t find replacement rubbers made specifically for your blades, you may have no choice but to replace the whole unit.

Replace the Whole Wiper Blade

Installing entirely new wiper blades provides the following advantages:

– Restore full wiping performance. Brand new blades will provide consistent downforce across the entire length of the windshield, allowing them to clear water and debris effectively.

– High quality rubber. Most replacement blades come with squeegee inserts made out of natural rubber, silicone or a synthetic blend. These cut down on noise and chatter compared to older rubbers.

– Easy to find. Any auto parts store will have a full selection of popular replacement wiper sizes. Matching your vehicle’s original blades is straightforward.

– Long lifespan. You’ll get a fresh supply of rubber that should last 6 months to a year before needing replacement.

– Consistent pressure. New wiper frames provide ideal spring tension without any weak spots or wear.

– Latest blade styles. Upgrading gives you access to modern beam styles, joint types and attachment designs that may work better than your old blades.

However, complete replacements do have some disadvantages:

– More expensive upfront cost. You’ll typically pay double or more the price versus just getting replacement squeegee inserts.

– Trash the old blades. Even if the frame and connections are functional, the old unit will end up in the garbage. Not ideal from an environmental perspective.

– Installation takes longer. You’ll need to carefully detach the old wiper arms and connect to the new blade assembly. This takes 5-10 minutes per wiper.

When to Only Replace the Rubber

Here are some signs that replacing just the squeegee inserts may be appropriate for restoring wiper performance:

– Blades are less than 2 years old. The frame and spring tension should still be in reasonable condition. Just needs fresh rubber.

– No major streaking, skipping or smearing. Issues are minor, pointing to the rubber wearing out rather than loss of tension or frame damage.

– Inserts are easy to detach. If you can pop out the old squeegees quickly, replacement inserts should snap right back in.

– Minimal cost. If money is a factor, renewal inserts are the way to go.

– Same length available. You can get replacement rubber squeegees in the exact length needed for your existing blades.

When to Replace the Whole Blade

Here are signs it’s time to replace the entire wiper blade assembly:

– Blades are more than 3 years old. The frame has likely lost tension and the overall integrity is declining.

– Severe streaking, smearing or skipping. Issues point to the whole system being compromised rather than just worn squeegee rubber.

– Cracking plastic or rust. Visual signs of blade deterioration indicate complete replacement is needed.

– Different model car. If you’ve bought a new vehicle that takes different length wipers, you’ll need new ones anyway.

– Difficult to remove insert. Fighting to detach the old rubber shows the system is seizing up. Get fresh blades.

– No insert replacements available. Your model may be discontinued or too old to find just the rubber.

Cost Comparison

To compare costs, let’s look at pricing examples for replacing the wiper blades on a 2018 Toyota Camry:

Replacement Type	Cost
Wiper Blade Inserts	$6
Complete Wiper Blades	$18

For just the pair of rubber inserts, you would pay around $12 total. To buy brand new wiper blades for both driver and passenger sides, you would pay $36. Of course, prices can vary between vehicle models and wiper brands, but this table demonstrates the basic cost difference.

How Long Do Wiper Blades Last?

Wiper blades gradually wear out over time and use. Here are some averages:

– Squeegee Rubber – 1 year
– Blade Frame – 3 years

Keep in mind these lifespans can vary a lot depending on climate, how often you use the wipers, and blade quality. Use the signs above like streaking and chatter to know when it’s time for replacement.

Can I Mix Old and New Blades?

It’s not recommended to pair one new wiper blade with one older blade. Here’s why this is problematic:

– Uneven force. The new blade will press against the windshield harder, while the old one has lost tension. This can lead to streaking.

– Different rubber. Alternating between fresh and worn squeegee rubbers usually causes skipping and juddering.

– Aging differences. After a few months, the new wiper will also deteriorate, leaving you with two poor blades.

For optimal visibility and cleaning, replace your blades in sets for the driver and passenger sides. Avoid mixing old and new.

Steps to Replace Windshield Wiper Inserts

Follow these steps to easily swap out old wiper blade inserts with new rubber squeegees:

1. Lift the wiper arm off the windshield. This gives you access to the blade underside.

2. Locate the tab or clip holding the rubber squeegee in place. It may slide off or require pressing a release.

3. Slide the old wiper insert out from the blade frame. Discard or recycle it.

4. Take the new replacement insert and slide it into the now empty wiper blade frame.

5. Press down firmly until the tabs or clips snap into place securely.

6. Carefully lower the wiper arm onto the windshield. Make sure the blade presses flat against the glass.

7. Repeat the process on the remaining wiper blades. Test that the wipers work properly before driving.

Steps to Replace Whole Wiper Blades

Follow these steps to swap out old wiper blades with new assemblies:

1. Lift the wiper arm off the windshield to access the blade.

2. Look for a small tab you press to detach the wiper from the arm. This releases the assembly.

3. With the wiper detached, grab the blade closest to the arm connection to slide it out from the rest of the frame.

4. Take your replacement blade and insert the end with the connector into the now empty wiper arm.

5. Press down the tab to lock the new blade securely into the arm. You should hear it click.

6. Carefully return the wiper arm onto the windshield so the new blade touches flush.

7. Repeat steps on the remaining old wiper to install the other new blade.

8. Run the wipers to ensure proper speed, coverage and pressure.

FAQs

How can I make my wiper blades last longer?

– Clean your windshield regularly with glass cleaner to prevent buildup

– Keep wiper blades protected from sun when not in use

– Avoid using blades on dry glass to minimize wear

– Check for and remove debris like ice or leaves stuck to the blades

– Apply silicone or rubber protectant sprays to condition the squeegees

Can I buy just one new wiper blade?

It’s strongly recommended to replace your blades in pairs to maintain even pressure on both sides of the windshield. Replacing just one will likely result in uneven wiping and streaking that obscures vision.

What are reflection wiper blades?

Reflection blades have a reflective foil coating on the upper part that bounces sunlight off the wiper to reduce heat and UV damage. This helps extend the lifespan of the rubber squeegee.

How do I know what wipers fit my vehicle?

Consult your owner’s manual for the correct wiper blade lengths and attachment types. You can also find wiper size lookups by vehicle make and model online or use the old blades to match new replacements.

Can I put silicone wipers on any car?

Silicone rubber wiper blades are a popular upgrade for a quieter wipe. However, you need to ensure the curve and attachments are right for your particular vehicle’s windshield shape and wiper arms.

Conclusion

When it’s time to replace worn out wipers, you have two main options – just swap the rubber squeegee inserts, or purchase complete new wiper blade assemblies. Factors like cost, ease of installation, and whether your existing frames are still functional help determine the best approach. Keep an eye out for signs of streaking, chatter and loss of contact pressure to know when your wipers need renewal. With fresh rubber squeegees or upgraded blades, you can clear your windshield and stay safe in all weather conditions.
