How long do Subaru front struts last?

Most Subaru front struts last about 60,000 to 100,000 miles under typical use, though the exact lifespan depends on model year, driving conditions, and maintenance. This article explains what affects durability, how to spot wear, and what to expect when replacing them.

Factors that affect strut longevity

Several conditions determine how long a strut set remains effective. The following factors can shorten or extend service life:

• Road conditions and driving style (potholes, speed bumps, aggressive driving)


• Climate and exposure to road salt or moisture (corrosion risk)


• Vehicle load and typical weight carried (cargo, passengers, towing)


• Quality and type of the struts (OEM vs aftermarket, gas-charged vs conventional)


• Maintenance practices (regular alignment checks, boot protection, leak monitoring)


• Previous suspension work and how closely related components are replaced (springs, mounts, bushings)

Because of these variables, there is no fixed lifespan. A routine inspection at milestones like 60,000 miles can help you plan maintenance before a failure occurs.

Signs that front struts may be worn

Watch for warning signs in daily driving. If you notice any of these, have a technician test the suspension as soon as possible:

• Visible leakage of hydraulic fluid around the strut body


• Excessive bouncing or poor damping after potholes or speed bumps


• Front-end sag or nose-diving when braking


• Unusual noises such as clunks or squeaks over bumps


• Uneven or accelerated tire wear and misalignment symptoms


• Damaged shock boots or mounting hardware

Early detection can prevent further damage to the suspension and tires. If multiple signs appear, plan a professional inspection and possible replacement.

Lifespan expectations by usage and Subaru model

Across Subaru models, a practical target range for front-strut service is typically within the following bands for normal driving, with adjustments based on your environment:

• Most drivers: 60,000–100,000 miles


• Heavy-use or rough roads (potholes, unpaved segments): 40,000–60,000 miles


• Low-mileage, highway-only use on smooth roads: 100,000 miles or more

These ranges reflect common experience, but individual results vary. If you drive in snowy regions, salt exposure can accelerate wear, and pothole-dense cities can shorten life. Always treat these as guidelines and rely on your mechanic's inspection findings.

Replacement options and process

When struts wear out, you have choices about parts and service. Budget, ride quality, and noise levels often guide the selection of parts and the scope of service.

Parts choices: OEM vs aftermarket

OEM Subaru struts preserve factory ride characteristics and are typically recommended for precise damping and longevity aligned with your vehicle’s suspension geometry. Aftermarket struts offer a range of damping options and price points, and high-performance variants are available for enthusiasts. No matter which path you choose, ensure the parts are compatible with your model year and come with a warranty.

What to expect during replacement

Most front strut replacement involves replacing both front struts on the same axle (and sometimes the coil springs and mounts are inspected or replaced as needed). The process typically includes an alignment after installation to restore proper steering geometry. Expect a few hours of labor per axle and a test drive to confirm proper operation. Prices vary widely by region, shop, and parts chosen.

Tips to extend front-strut life

Practical steps can help you get the most life from your Subaru’s front shocks and mounts:

• Avoid hitting potholes and speed bumps at high speed; slow down and steer through them when possible


• Keep tires properly inflated and wheels aligned; schedule regular alignment checks after suspension work


• Inspect strut boots for cracks or leaks and address corrosion from road salt promptly


• Pair strut replacement with related components (mounts, linkages) when wear is detected

Implementing these practices can help you maintain ride quality and extend the life of your suspension components.

Summary

In short, Subaru front struts typically last 60,000–100,000 miles under normal conditions, with shorter lifespans in rough driving environments and longer lifespans when well-maintained. Regular inspections, attention to signs of wear, and timely replacement—often in pairs—help preserve handling, tire life, and safety. Always consult a qualified mechanic for a precise assessment and replacement plan tailored to your model and driving conditions.

What is the life expectancy of a front strut?

Front struts typically last between 50,000 and 100,000 miles, but this can vary depending on driving conditions. Factors like driving on rough roads, aggressive driving, or frequent heavy loads will shorten their lifespan, while gentle driving on smooth surfaces will extend it. Key signs to watch for that indicate replacement is needed include excessive bouncing, leaning during turns, oil leaks from the strut, or a bumpy and unstable ride.

Typical lifespan

• General guideline: 50,000 to 100,000 miles. 
• Aggressive driving: Driving on bumpy roads, towing, or aggressive driving will wear them out faster, potentially requiring replacement sooner. 

Signs that struts need replacement

• Excessive bouncing: The vehicle bounces more than a few times after hitting a bump or pothole. 
• Poor handling: The car sways or leans when changing lanes or making turns. 
• Leaking fluid: A visible sign of wear is oil leaking from the strut. 
• Steering issues: The steering wheel feels stiff or difficult to turn, especially on uneven roads. 
• Braking problems: The vehicle "dives" excessively when you brake. 
• Uneven tire wear: You may notice uneven wear patterns on your tires, such as cupping.

Important considerations

• Always have your suspension checked by a professional if you notice any of these signs. 
• Have your suspension inspected annually, or with every alignment and tire rotation, to catch potential issues early. 
• Struts should always be replaced in pairs (both the left and right front struts) to ensure even performance. 

When to replace struts on a Subaru?

Signs indicating that it's time to replace your struts may include uneven tire wear, a bumpy ride, or difficulty steering. If you're experiencing any of these symptoms, it's crucial to have your struts inspected by a skilled mechanic.

How much to replace struts on a Subaru?

The cost to replace Subaru struts can range from $800 to over $3,000, depending on the vehicle, the type of parts used (aftermarket vs. genuine), and whether both front and rear struts are replaced. A typical independent shop with aftermarket parts might charge between $800 and $1,000 for a full set of rear struts including labor, while a dealership using genuine parts can cost significantly more, with some estimates exceeding $3,000 for a full job. 
Cost breakdown and factors

• Parts: The cost of the struts themselves varies. 
  • Aftermarket: Can be around $300 for a set of shocks and springs. 
  • Genuine Subaru: A single front strut can have an MSRP of $170-$180, but this does not include installation or other fees. 
• Labor: Labor costs depend on the complexity of the job and the shop's hourly rate. 
  • An independent shop might charge around $500 for labor to replace both rear struts. 
  • Dealerships typically have higher labor rates and may charge more for the same work. 
• Vehicle Model and Year: Older or specific models may have different part costs and labor times. For example, a 2017 Forester front strut replacement could cost between $2,474 and $3,471 at a shop or dealership, while a 1999 Forester rear replacement might be estimated between $2,058 and $2,944. 
• Full vs. Partial Replacement: Replacing all four struts will cost more than replacing just the front or rear set. 

How to get an accurate quote

• Contact a local independent mechanic and a Subaru dealership for quotes specific to your vehicle's year, make, and model.
• Ask for a detailed breakdown of costs for parts and labor.
• Inquire about the brands of parts they use to understand the difference between aftermarket and genuine parts.

Can struts last 150k miles?

As a general guideline: - Shock absorbers/struts: 50,000 to 100,000 miles. - Control arms: 90,000 to 100,000 miles. - Ball joints: 70,000 to 150,000 miles.
