Ford Explorer (2002-2014) Suspension Strut and Coil Spring Assembly Reference
Restore your Explorer's ride quality and handling by understanding how to choose the right replacement strut assembly.
- Verify your Explorer's generation (2002-05, 2006-10, 2011-14) before ordering, as suspension parts are not interchangeable.
- For 2011-2014 models, complete strut assemblies are only for the front; the rear has separate shocks and springs.
- Always replace struts in pairs (both front or both rear) to ensure safe, predictable handling.
- A wheel alignment is mandatory after replacing strut assemblies to prevent tire damage and handling issues.
Generational Differences: What You Need to Know
The 2002-2014 Ford Explorer spans three different generations, and their suspension designs have important differences. It is critical to order the correct part for your specific year.
- 2002-2005 (Third Generation): These models use a four-wheel independent suspension. They have strut assemblies on the front and a coil-over-shock assembly on the rear, which functions very similarly to a front strut assembly.
- 2006-2010 (Fourth Generation): Similar to the third generation, these Explorers use front strut assemblies and rear coil-over-shock assemblies. Parts are often not interchangeable with the previous generation. 🎬 Watch: Step-by-step front strut replacement for 2006-2010 models
- 2011-2014 (Fifth Generation): This generation saw a major platform change. They use strut assemblies in the front, but the rear suspension is a multi-link design with a separate shock absorber and coil spring. A complete "strut and coil spring assembly" is not available for the rear of these models; the shock and spring must be purchased separately.
Known Issues & Recalls
While there are no direct recalls for the strut assemblies themselves, several major suspension recalls affect the 2011-2014 models. Owners of 2011-2013 Explorers, especially in salt-belt states, should be aware of NHTSA recall 21S43. This recall addresses a rear suspension toe link that can fracture due to corrosion, leading to a loss of steering control. While not the strut, it is a critical suspension failure point. A common problem on earlier 2002 models is rear coil spring failure. Always check for recalls using your vehicle's VIN on the NHTSA website.
Signs of a Failing Strut Assembly
Worn struts can make your Explorer feel unstable and unsafe. Look for these common symptoms:
🎬 Watch: 5 symptoms of bad struts you should not ignore- Bouncy, Unstable Ride: The vehicle bounces multiple times after hitting a bump.
- Clunking or Knocking Noises: You hear metallic clunks when driving over uneven roads. This is a primary sign of wear.
- Nose-Diving and Body Roll: The front of the Explorer dips excessively when braking, or the body leans heavily in turns.
- Uneven Tire Wear: Worn struts can cause "cupping" or scalloped wear patterns on your tires.
- Fluid Leaks: Oily fluid seen on the body of the strut indicates the internal seals have failed.
Choosing the Right Aftermarket Strut Assembly
Replacing the entire strut assembly (often called a "quick strut") is much easier and safer than replacing only the strut and reusing the old spring. It ensures all related components are new. Aftermarket brands offer a range of options.
Economy & Standard Replacement
Brands like FCS, Unity, and PRT offer affordable, direct-fit replacements. They are a good choice for daily driving and restoring the original ride quality on a budget. They meet OEM specifications and provide a safe, reliable repair.
OE-Quality & Premium
Brands like KYB and Monroe are well-known names that often supply original parts to manufacturers.
- KYB: Often considered to provide a slightly firmer ride than stock, which can improve handling and stability. They are a popular choice for owners looking for a modest performance upgrade.
- Monroe: Generally designed to restore the original factory ride feel. They are a trusted option for a comfortable and controlled ride, though some users report they feel softer than KYB.
- Mando: A large OEM supplier, Mando provides high-quality parts that are engineered to match the original vehicle performance.
Pro Tip: Replace in Pairs
Always replace strut assemblies in pairs (both front or both rear). Replacing only one can cause uneven ride height, poor handling, and unpredictable steering.

Frequently Asked Questions
Do I need a wheel alignment after replacing struts?
Yes, absolutely. Replacing a strut assembly will change your vehicle's suspension geometry. A four-wheel alignment is required to prevent rapid tire wear and ensure the vehicle handles safely.
Can I replace just the strut or should I buy the whole assembly?
While you can replace just the strut cartridge, it requires a special tool called a spring compressor, which can be dangerous to use. Buying a complete assembly is safer, faster, and ensures the coil spring and strut mount are also new, preventing future problems.
Will new struts change my Explorer's ride height?
If your old springs were sagging, new strut assemblies will likely restore your Explorer to its original factory ride height. This can sometimes result in a slight lift in the front or rear if the old components were significantly worn.
What is the difference between front and rear suspension on the 2011-2014 Explorer?
The 2011-2014 models use a front strut assembly but have a separate rear shock and coil spring. You cannot buy a single "assembly" for the rear. You must purchase the rear shocks and rear coil springs as individual components.
