A Guide to Replacing Suspension Struts on Your 2012-2018 Chrysler 300
Restore your Chrysler 300's smooth ride by understanding when and how to replace your suspension struts.
- Always replace struts in pairs (front or rear) to maintain vehicle stability.
- Purchase complete strut assemblies ('quick struts') to simplify installation and renew all related components.
- A wheel alignment is mandatory after strut replacement to prevent poor handling and uneven tire wear.
- Verify if your Chrysler 300 is RWD or AWD before ordering, as the parts are not interchangeable.
Is It Time to Replace Your Chrysler 300's Struts?
The struts on your Chrysler 300 wear out gradually. You might not notice the slow decline in ride quality. However, there are common symptoms that indicate it's time for a replacement. Ignoring these signs can lead to faster wear on other suspension parts and tires.
Common Failure Symptoms:
🎬 Watch: A mechanic's guide to diagnosing bad shock and strut symptoms.- Bouncy or Unstable Ride: If your 300 feels like it's bouncing excessively after hitting a bump or feels floaty and unstable on the highway, the struts are likely worn.
- Nose-Diving and Squatting: When you brake, does the front end of the car dip down noticeably? Or does the rear end squat during acceleration? This is a classic sign of failing struts.
- Unusual Noises: Listen for clunking, knocking, or rattling sounds, especially when driving over bumps or turning. This can be caused by worn internal components or failing strut mounts.
- Uneven Tire Wear: Worn struts can cause the tires to bounce, leading to cupped or scalloped wear patterns on the tread.
- Fluid Leaks: A visual inspection might reveal oily fluid leaking down the side of the strut body. This indicates the internal seals have failed and the strut needs immediate replacement.
Recalls and Technical Service Bulletins (TSBs)
While there are no specific recalls from the NHTSA for suspension struts on the 2012-2018 Chrysler 300, there have been recalls for other suspension-related components and numerous other issues for this vehicle generation. It is always a good practice to check for any open recalls on your specific vehicle. No widespread Technical Service Bulletins (TSBs) directly related to premature strut failure were found during research.
Choosing the Right Aftermarket Strut
When replacing your struts, you'll find OEM (Original Equipment Manufacturer) parts and a wide variety of aftermarket options. For the 2012-2018 Chrysler 300, aftermarket struts can offer a significant cost saving without a major compromise in quality, especially from reputable brands. Many owners choose complete strut assemblies, also called "quick struts," which include the strut, coil spring, and mount all in one unit. This simplifies installation and ensures all related components are new.
Aftermarket Brand Tiers for Chrysler 300:
- Premium/Performance (Better than OEM): Brands like Bilstein offer performance-oriented struts that can improve handling and control beyond the original factory feel. These are a great option for owners looking for an upgrade.
- OEM-Quality (Good): Brands like KYB and Monroe are well-regarded in the aftermarket. They aim to restore the original ride quality and performance of your 300. They are a popular and reliable choice for daily driving.
- Economy (Value-Oriented): Brands like FCS and PRT provide a budget-friendly option. While they can be a good choice for those looking to sell the vehicle or who are on a tight budget, some user reviews suggest their ride quality may be softer and their lifespan may not be as long as premium or OEM-quality brands.
Pro Tip: Always replace struts in pairs (both front struts or both rear struts). 🎬 Watch: How to replace the rear shocks on your Chrysler 300. Replacing only one can lead to unbalanced handling and instability. Also, plan for a wheel alignment after the replacement to ensure proper handling and prevent premature tire wear.

Frequently Asked Questions
Do I have to replace the coil spring with the strut?
Not necessarily, but it is highly recommended. A complete strut assembly (or "quick strut") includes a new strut, spring, and mount. This is often safer and easier to install than disassembling the old unit to reuse the spring, which requires a special spring compressor tool. Over time, coil springs can also weaken and sag.
Can I replace just one strut?
No, you should always replace struts in pairs (both front or both rear). Mismatched struts can cause unpredictable handling, uneven braking, and vehicle instability.
Is a wheel alignment necessary after replacing struts?
Yes, absolutely. Replacing struts will alter your vehicle's suspension geometry. A wheel alignment is required to correct the camber, caster, and toe angles to prevent unsafe handling and rapid tire wear.
What's the difference between RWD and AWD struts?
The struts for Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD) Chrysler 300 models are different and not interchangeable. The AWD suspension is designed to accommodate the front drive axles. Always ensure you are purchasing the correct parts for your specific drivetrain.
