Why Your ASE Tech Recommends Replacing Both Struts Instead of One
I remember the moment clearly—the jarring clunking sound from my front wheel, a shaky steering wheel, and the sinking feeling that I was about to shell out more than I expected. As an ASE-certified technician and a car enthusiast, I’ve seen firsthand how drivers often think replacing just one strut will do the trick, only to find themselves back in the shop sooner than they hoped. That lightbulb moment made me realize how crucial it is to understand why replacing both struts can save you money and headaches in the long run.
The Real Reason Your ASE Tech Recommends Double the Replacement
Many car owners are tempted to opt for the cheapest fix—just swap out the visibly damaged strut. But here’s the truth: your suspension components wear out gradually and tend to do so at similar rates. Replacing only one strut might seem cost-effective initially, but it often leads to uneven wear, compromised steering, and premature failure of the new part. That’s why my seasoned colleagues and I always recommend replacing *both* when one shows signs of wear. Doing so ensures balanced handling, preserves alignment, and extends the lifespan of your suspension system.
Is the Cost of Replacing Both Worth It?
It’s completely understandable to hesitate at the additional expense. However, studies show that uneven suspension wear can lead to dangerous driving conditions and higher repair costs down the road. Think of it like putting a band-aid on part of a leaking pipe—you’re just delaying the inevitable. Trust me, your safety and your wallet will thank you later if you heed the advice of a trained technician who knows this secret to long-term vehicle health.

Now, I’m sure some of you might be wondering whether this strategy is truly necessary or just a salesperson’s gimmick. Well, I’ve made my share of mistakes early in my career—assuming front-end repairs were always enough—only to see the problems come back months later. That’s why I want to share what I’ve learned, so you don’t have to go through the same guesswork.
Now that I’ve set the stage, let’s dive into the details of why replacing both struts isn’t just a good idea—it’s a smart one. We’ll walk through the signs, benefits, and common misconceptions, making sure you’re fully equipped to make informed decisions about your vehicle’s suspension system.
Prepare Your Tools and Workspace
Start by gathering necessary tools: a hydraulic jack, jack stands, socket sets, and a wrench. Ensure your workspace is flat, well-lit, and free of obstacles. Remember, a clean and organized environment reduces the risk of mistakes when working on your suspension. I once left a wrench on the driveway, only to back over it—costly and frustrating. Keeping everything in reach simplifies the process and speeds up your repair.
Safely Lift Your Vehicle
Use the hydraulic jack to lift the vehicle at manufacturer-recommended lift points, then place jack stands for stability. Double-check the vehicle is secure before crawling underneath. When I replaced my first pair of struts, I initially placed the jack on a soft surface; the vehicle shifted slightly, which was a wake-up call. Properly secured vehicles prevent accidents and provide a stable working environment.
Identify and Remove the Old Struts
Locate the damaged struts—usually connected to your wheel assembly—and remove the wheels for better access. Detach any cotter pins, bolts, or clips holding the strut in place. Compare the worn strut with the new one to confirm they’re identical. During my first swap, I mistakenly ordered the wrong size, wasting hours troubleshooting. Double-checking part numbers beforehand avoids such mishaps.
Compress and Install the New Struts
If your new struts come uncompressed, use a compressor or spring retainer to safely compress the coil spring. Carefully remove the old strut and install the compressed new one onto the suspension assembly. Always follow manufacturer torque specifications, which I learned the hard way—over-tightening caused damage. Consult your vehicle’s service manual or trusted resources to get the correct values.
Secure Everything and Test
Reattach all bolts, clips, and components in reverse order. Ensure all fasteners are torqued to spec, and double-check your work. Remove the jack stands and carefully lower the vehicle. After completing the replacement, I recommend taking a short test drive to feel for proper handling. If you notice uneven steering or vibrations, revisit the installation steps—precision is key in suspension work.

One prevalent myth is that an oil change is solely about changing the oil; however, proper oil service involves checking and replacing filters, inspecting vital components, and understanding the correct intervals to prevent engine wear. Relying solely on mileage or time can be misleading, as driving conditions dramatically influence oil degradation. For instance, short trips in cold weather accelerate engine oil breakdown, making adherence to recommended oil change intervals essential for longevity.
Another common misconception concerns transmission maintenance. Many assume that if their vehicle shifts smoothly, nothing needs to be done. But transmission fluid can deteriorate silently, causing delayed engagement or slipping. Experts highlight that regular checks and timely fluid exchanges—guided by a qualified technician—can save a fortune later. Studies support this, emphasizing the impact of clean transmission fluid on *smooth gear shifting* and avoiding expensive repairs. Don’t wait for warning lights to take action; proactive maintenance is key.
On the topic of certifications, some believe that a general mechanic’s experience outweighs the value of ASE certification. Contrary to this assumption, ASE-certified technicians have demonstrated proficiency in critical areas like suspension, brakes, and electrical systems. This accreditation ensures adherence to industry standards and comprehensive knowledge essential for complex issues. Knowing this, car owners can make smarter choices by opting for certified shops, which significantly reduces the risk of missed diagnostics or subpar repairs.
Now, for the sophisticated drivers out there wondering about the nuances—
How does an ASE certification influence your car’s resale value?
According to industry experts, vehicles maintained by ASE-certified technicians tend to retain value better, as documented in this detailed analysis. Certification ensures the work meets high standards, leading to fewer callbacks and a longer vehicle lifespan, which appeal to prospective buyers.

Keeping It Working: Essential Tools and Maintenance Strategies
Maintaining your vehicle’s health over time requires more than just basic skills; it demands the right tools, disciplined practices, and a proactive mindset. One of my favorite investments is a high-quality digital multimeter. I prefer the Fluke 115, because it provides precise readings for battery health, sensor outputs, and electrical system diagnostics. When I check voltage levels or hunt for parasitic drains, this tool’s accuracy saves me hours of guesswork and prevents unnecessary part replacements.
Another must-have is a compression tester. I rely on the Innova 3612, which offers quick readings to assess engine health without removing the cylinder head. It’s especially valuable when diagnosing oil consumption issues or checking for internal wear, helping me determine if an engine overhaul is necessary before costly repairs.
For suspension work, I prefer a spring compressor with a trusted brand like OTC. Using a robust spring compressor is essential for safely removing and installing coil springs, which are under immense tension. There’s no shortcut here; a failure to use proper equipment can be dangerous. This tool’s durability and reliable design have prevented me from potential injuries during wheel well overhauls.
Modern diagnostics lean heavily on software, so I recommend the OBD2 scanner from BlueDriver. It provides comprehensive codes, live data, and customized repair reports.
