February 24, 2025

Keep Your Suspension in Top Shape with Crown City Tire Auto Care in Pasadena, CA

Your vehicle’s suspension system is a critical component that ensures a smooth and safe ride. However, one of the biggest threats to your suspension’s longevity is rust and corrosion. If left unchecked, rust can weaken suspension parts, leading to costly repairs and even dangerous driving conditions. At Crown City Tire Auto Care, with locations at 80 W Bellevue Dr and 3161 E Foothill Blvd in Pasadena, CA, we understand the importance of maintaining a rust-free suspension system. In this guide, we’ll explore practical ways to prevent rust and corrosion, helping you keep your car’s suspension in peak condition.


Understanding Rust & Corrosion in Suspension Components

Rust forms when metal is exposed to moisture and oxygen over time. Suspension components such as control arms, ball joints, struts, and springs are particularly susceptible, especially in areas where roads are treated with salt or exposed to high humidity levels. If rust develops, it can compromise the structural integrity of these parts, leading to reduced performance and potential safety risks.


Common Causes of Suspension Rust

  • Exposure to Moisture – Rain, snow, and even morning dew can contribute to rust formation.
  • Road Salt & Chemicals – De-icing salt used in colder climates accelerates corrosion.
  • Lack of Protective Coatings – Factory coatings wear off over time, exposing bare metal to the elements.
  • Poor Drainage – Water accumulation in wheel wells and undercarriage areas can lead to prolonged exposure.
  • Neglected Maintenance – Failure to regularly clean and inspect the undercarriage allows rust to spread unnoticed.


Proactive Measures to Prevent Suspension Rust


1. Wash Your Car Regularly

Dirt and grime trap moisture, which speeds up rust formation. Make it a habit to wash your vehicle, paying close attention to the undercarriage where suspension components are located. A high-pressure rinse will help remove debris and salt residue, especially after driving through rain or on treated roads.


2. Apply Rust-Proofing Treatments

A protective coating, such as an anti-rust spray or undercoating, can create a barrier against moisture and road salts. At Crown City Tire Auto Care in Pasadena, CA, we offer rust prevention treatments that help extend the life of your suspension system.


3. Inspect Your Suspension Regularly

Routine inspections can help identify early signs of rust before they cause serious damage. Look for discoloration, flaking metal, or bubbling paint on suspension parts. If you’re unsure, schedule a suspension inspection at Crown City Tire Auto Care—our experienced technicians can spot and address issues before they escalate.


4. Use Protective Sprays & Lubricants

Spraying your suspension components with a water-displacing lubricant (such as WD-40 or a silicone-based spray) can help keep moisture at bay. This is particularly useful for moving parts like ball joints and tie rods.


5. Keep Drainage Areas Clear

Clogged drain holes in the undercarriage and wheel wells can lead to standing water, increasing the risk of rust. Check these areas regularly and remove any blockages to allow proper water drainage.


6. Park in a Covered Area

Whenever possible, park your vehicle in a garage or covered parking space to reduce exposure to rain, humidity, and dew. If you park outside, consider using a car cover for added protection.


7. Schedule Routine Suspension Maintenance

Preventative maintenance is key to avoiding costly repairs. Our team at Crown City Tire Auto Care provides comprehensive suspension maintenance services in Pasadena, CA, ensuring that your vehicle stays rust-free and road-ready.


What to Do If You Spot Rust on Your Suspension

If you notice rust forming on your suspension components, don’t wait until it worsens. Light surface rust can sometimes be removed with a wire brush and a rust converter. However, if the rust has penetrated deeper, it’s best to have a professional assess the damage. Bring your vehicle to Crown City Tire Auto Care for an expert evaluation and repair recommendations.

We all love that fresh, clean feeling when we step into our cars, especially after a long day navigating the bustling streets of Pasadena. But have you ever stopped to think about the air you're actually breathing inside your vehicle? Often overlooked, the cabin air filter plays a crucial role in the quality of your in-car environment. At Crown City Tire Auto Care in Pasadena, we believe in empowering our customers with the knowledge to keep their vehicles running smoothly and their occupants healthy. So, let's dive into the often-neglected world of the cabin air filter and uncover the dirty truth about when it's time for a replacement. For many drivers in Pasadena and beyond, the engine air filter gets all the attention. It makes sense – it's directly linked to engine performance and fuel efficiency. However, the cabin air filter, while not impacting how your car runs, significantly affects the air you and your passengers breathe. Think of it as the air purifier for your vehicle's interior. It's designed to trap dust, pollen, mold spores, pet dander, and even airborne pollutants that can enter your car's ventilation system from the outside. Why Should Pasadena Drivers Care About Their Cabin Air Filter? Living in a vibrant city like Pasadena, CA, exposes our vehicles to a variety of environmental factors. From the seasonal blooms releasing pollen into the air to the everyday dust and smog of urban driving, our car interiors can become surprisingly contaminated. A clogged or dirty cabin air filter can lead to a host of issues, some you might not even realize are connected: Reduced Airflow: A blocked filter restricts the amount of air that can pass through your car's heating and cooling system. This can lead to weak airflow from your vents, making it harder to heat or cool your cabin effectively, especially during those hot Pasadena summers or cooler winter evenings. We've seen many customers at Crown City Tire Auto Care surprised at the improvement in their AC performance after a simple cabin air filter replacement. Unpleasant Odors: Over time, trapped particles and moisture in the filter can become breeding grounds for bacteria and mold, leading to musty or unpleasant odors circulating in your car. If you've noticed a persistent stale smell, even after cleaning your interior, your cabin air filter could be the culprit. Allergic Reactions and Respiratory Issues: For allergy sufferers or individuals with respiratory sensitivities living in Pasadena, a clean cabin air filter is paramount. A dirty filter recirculates allergens and irritants, potentially exacerbating symptoms like sneezing, coughing, and itchy eyes. Replacing your filter regularly can significantly improve the air quality and comfort for everyone in the vehicle. Strain on Your HVAC System: When the cabin air filter is clogged, your car's blower motor has to work harder to push air through. This increased strain can potentially shorten the lifespan of components in your heating, ventilation, and air conditioning (HVAC) system, leading to more costly repairs down the line. At Crown City Tire Auto Care in Pasadena, we always recommend preventative maintenance to avoid such issues. So, When Exactly Should Pasadena Drivers Replace Their Cabin Air Filter? While there's no one-size-fits-all answer, several factors can help you determine when it's time for a new cabin air filter in your vehicle: Manufacturer Recommendations: Your vehicle's owner's manual will typically provide a recommended replacement interval for the cabin air filter. This is a good starting point, often suggesting replacement every 12,000 to 15,000 miles or once a year. We at Crown City Tire Auto Care generally advise following these guidelines as a minimum. Visual Inspection: One of the easiest ways to check your cabin air filter is to visually inspect it. The location of the filter varies depending on your vehicle's make and model, but it's often located behind the glove compartment or under the dashboard. Consult your owner's manual for the exact location. Once you've accessed it, take a look. A clean filter will be relatively white or light gray. If it's visibly dirty, clogged with debris, or dark in color, it's definitely time for a replacement. We often show our customers in Pasadena their old filter versus a new one – the difference can be quite striking! Reduced Airflow: As mentioned earlier, a noticeable decrease in the airflow from your vents is a strong indicator of a clogged cabin air filter. If you find yourself turning the fan up higher than usual to achieve the same level of cooling or heating, have your filter checked. Unpleasant Odors: If you consistently notice musty or other unpleasant smells when your ventilation system is running, your cabin air filter is likely trapping odor-causing particles and needs to be replaced. Allergy Season and Driving Conditions in Pasadena: If you frequently drive in dusty conditions, heavy traffic with exhaust fumes, or during peak allergy seasons in Pasadena, your cabin air filter will likely need more frequent replacement. These conditions expose your filter to a higher volume of contaminants. Time Since Last Replacement: Even if you haven't driven many miles, the filter material can degrade over time and lose its effectiveness. If it's been over a year since your last cabin air filter replacement, it's a good idea to have it checked, especially considering the air quality in and around Pasadena. What Happens During a Cabin Air Filter Replacement at Crown City Tire Auto Care? When you bring your vehicle to Crown City Tire Auto Care in Pasadena for a cabin air filter replacement, our experienced technicians will: Locate the Cabin Air Filter: We'll identify the precise location of your vehicle's cabin air filter based on its make and model. Remove the Old Filter: We'll carefully remove the old, dirty filter. You'll likely be surprised at the amount of debris it has collected! Inspect the Housing: We'll check the filter housing for any signs of damage or excessive buildup. Install a New, High-Quality Filter: We use high-quality cabin air filters that meet or exceed manufacturer specifications, ensuring optimal filtration and airflow. Verify Proper Airflow: After installing the new filter, we'll test your vehicle's ventilation system to ensure proper airflow and functionality. Investing in Your In-Car Air Quality with Crown City Tire Auto Care Replacing your cabin air filter is a relatively inexpensive yet highly impactful maintenance task. It's a simple way to improve the air quality inside your vehicle, enhance the performance of your HVAC system, and contribute to a more comfortable and healthier driving experience, especially here in Pasadena.
