How Often Should Struts Be Replaced?

Struts, those unsung heroes of suspension systems, play a crucial role in maintaining the smoothness and stability of your vehicle’s ride. But just like any other automotive component, they eventually wear out and need to be replaced. The question is: how often? Fear not, dear reader, for in this informative article we will delve into the depths of struts maintenance and guide you on the journey to strut replacement enlightenment.

Understanding Strut Lifespan

To determine how frequently you should replace your struts, it’s essential first to grasp their lifespan. Struts are designed to endure many miles of driving over various road conditions. However, several factors come into play when assessing their longevity:

Factor 1: Driving Conditions

The roads we traverse can vary dramatically from smooth highways to pothole-riddled nightmares that seem more suited for moon buggies than cars. Harsh driving conditions, such as encountering countless bumps and craters or driving on rough terrain, can significantly impact the lifespan of your struts.


“It’s no surprise that frequently traveling on challenging surfaces accelerates strut wear. “

Factor 2: Miles Driven

As with most automobile components, mileage plays a significant role in determining when struts require replacement. Sadly, there is no set number that applies universally across all vehicles. Each manufacturer has its own recommended interval for replacing struts based on average usage patterns.

– Some automakers suggest replacing struts every 50k miles.
– Others recommend inspection and potential replacement around 70k miles.

Let’s say you drive an average of 12k miles per year. You can expect your struts may start showing noticeable signs of wear after approximately six years behind the wheel.

Signs That Your Struts May Be Worn Out

Before tossing out perfectly functional pieces of your suspension system, it’s crucial to recognize the symptoms of worn-out struts:

Symptom 1: Excessive Bouncing

If you find your vehicle bouncing up and down excessively after encountering a bump or pothole, it could be a clear indication that your struts have lost their shock-absorbing abilities and are long overdue for replacement.

Symptom 2: Uneven Tire Wear

Worn-out struts can wreak havoc on your tires. If you notice excessive wear on the inside or outside edges of your tires, it may be due to a misalignment caused by faulty struts.

Symptom 3: Nose Dives and Body Roll

When braking suddenly, do you feel like the front end of your car dives forward dramatically? Or perhaps engaging in cornering makes your vehicle lean excessively? These issues not only compromise handling but also suggest that the suspension system is crying out for new struts.

– Worn-out struts can contribute to an increase in stopping distances by as much as 10%.

Determining Strut Replacement Frequency

Now comes the moment you’ve all been waiting for – how often should those trusty old struts be replaced? Although there isn’t a one-size-fits-all answer, here are some general guidelines:

Guideline 1: Manufacturer Recommendations

The first stop on our strut replacement journey takes us straight to the manufacturer’s recommendations. Consult your vehicle owner’s manual or get familiar with the automaker’s website to unearth their specific guidelines regarding strut maintenance and replacement intervals. After all, the folks who built your car probably know best when it comes to keeping it running smoothly.

Guideline 2: Visual Inspection

H3 Heading Below Some Paragraphs

Inspecting Your Struts Regularly
Catch subtle signs such as hollow clunking sounds or oil leaks emanating from the strut piston rod which could mean that they have lost their internal gas charge and are no longer providing optimal suspension performance.
Finding: Interior areas of maintenance shops heed inspection every two months while daily drivers inspections take place once every month.
When noticed visible signs of failure, immediately conduct a visual inspection before proceeding with high-speed driving exploits.
Suggestion for Repair: Put off serious negative impacts opting for replacing struts in pairs until you can afford them or plan other components in tandem

A regular visual inspection can provide vital clues about the health of your struts. Look for any signs of leakage, pitting, or corrosion on the surface. If there is significant damage or noticeable wear on one strut, it’s generally recommended to replace both front or rear struts at the same time.

Guideline 3: Mileage Markers

While mileage alone isn’t an accurate predictor of strut wear, taking note of specific mileage milestones can serve as a helpful reminder to carry out proper inspections:

  • Around 50k miles: Perform a thorough examination to check for any early signs of wear and tear.
  • Between 70k – 100k miles: Consider replacing your struts if you haven’t done so already. These higher mileage ranges often correlate with increased chances of worn-out components.
  • Every subsequent 50k miles: Re-evaluate your struts’ condition and gauge whether replacement is necessary.

1. Manufacturer recommendations should always be followed first.
2. Perform visual inspections regularly – catch those subtle warning signs!
3. Keep mileage markers in mind as a reminder to inspect and potentially replace your struts.

The Importance of Timely Strut Replacement

Delaying the replacement of worn-out struts can have several negative consequences. Apart from compromising your vehicle’s ride comfort, it can affect other critical systems including:

  • Steering responsiveness, leading to a loss of control in emergency situations.
  • Braking distance and overall stopping power, which could jeopardize safety on the road.
  • Uneven tire wear, resulting in premature tire deterioration that not only costs you money but also decreases driving stability.

Common Misconceptions About Struts

Now that we’ve covered the importance of replacing worn-out struts promptly let’s tackle some common misconceptions surrounding strut maintenance:

Misconception 1: If It Ain’t Broke, Don’t Fix It!

While it may be tempting to adopt this philosophy for some aspects of life, ignoring the gradual degradation of your struts is not advisable. Remember that timely maintenance helps ensure optimal performance and safety.


“Don’t wait until you’re careening around corners like Vin Diesel in a Fast & Furious movie before considering new struts. “

Misconception 2: Replacing Only One Strut Is Sufficient

It’s important to avoid mixing old and new when it comes to replacing your struts. For optimal ride quality and balance, always replace both front or rear strut pairs simultaneously.

Mixing old and new shocks can lead to uneven damping between left/right sides
Independent evaluations suggest maintaining working suspension intermittently – avoid having significant variations at one extreme where both sides are equally degraded – simultaneous replacement helps ensure handling, stability and tire wear rates meet a consistent standard.

Consider this scenario: You own an aging sedan. The right front strut has failed, and you decide to replace only that one strut. A few weeks later, you encounter a dreaded pothole extravaganza on the left side of town. This uneven impact can potentially damage the remaining old strut, leading to an unbalanced suspension setup.

Misconception 3: Any Old Replacement Will Do

Struts are not generic components; they are specifically designed for each vehicle’s weight distribution and suspension geometry. Opting for subpar replacements may compromise your car’s performance and safety.

When replacing struts, it is advisable to stick with Original Equipment Manufacturer (OEM) parts or high-quality aftermarket alternatives approved by reputable manufacturers.

Strut replacement frequency varies depending on several factors such as driving conditions, mileage driven, manufacturer recommendations, visual inspections, and specific milestones. By adhering to manufacturer guidelines, conducting regular inspections, and knowing the signs of worn-out struts – excessive bouncing or uneven tire wear – you’ll be one step ahead in maintaining your vehicle’s optimal performance levels.

Remember: delay in replacing worn-out struts can lead to compromised safety measures like reduced steering responsiveness or braking distance along with adverse effects on other suspension components. Don’t fall prey to common misconceptions like ignoring gradual degradation or replacing just one strut when both sides need attention simultaneously.

Stay informed about your vehicle’s maintenance needs because taking care of those dependable struts will ultimately reward you with better control over bumpy roads and smoother rides into the future!
