What is a strut assembly?
A strut assembly is an important part of many suspension systems. It’s a combined shock absorber-coil spring unit designed to help support your vehicle’s weight, absorb shocks and vibrations, and help maintain stability.
When should I replace the strut assemblies on my car?
There is no set replacement interval for strut assemblies but they tend to wear out after 50,000 to 100,000 miles. You’ll only need to replace your struts if they fail or you want an upgrade. The most common signs of worn-out struts include the following:
Noises when driving over bumps: If you hear clunking or knocking noises while driving over bumps or potholes, it could be a sign that you need new struts.
Poor ride quality: A common symptom of bad struts is a bumpy, uncomfortable ride. Some bounces are normal when driving over rough terrain but if you can feel every crack and bump in the road or your ride feels lurchy and rough, you may need new struts.
The car pulls to one side: If your car pulls to one side, it can be a sign that it’s out of alignment—but it can also indicate worn-out struts. The struts play a key role in front-end alignment so if you notice the car pulling to one side, the struts may be to blame.
Uneven tire wear: When the struts wear out, they can’t absorb shocks properly. This can cause your tires to lose contact with the road momentarily, leading to uneven tire wear.
Keep in mind: These problems can indicate other steering and suspension system issues. The best way to properly diagnose your car’s problem is to visit a certified mechanic.
How often should I replace my strut assemblies?
There generally isn’t a fixed replacement interval for strut assemblies, though you should check your owner’s manual to be sure. Struts tend to wear out after around 50,000 to 100,000 miles. You’ll need to replace yours if you experience signs of strut failure, which can include clunking noises, a bumpy ride, and uneven tire wear.
Can I replace my strut assemblies myself?
A strut assembly replacement is a mid-to-advanced-level repair job. While it can be a great DIY project for experienced hobbyists and home mechanics, it’s likely too complex for novices.
If you’re not comfortable working with your vehicle’s suspension system, you should contact a professional mechanic.
