2015 Subaru Legacy/Liberty Struts — What They Do and When to Replace

Based on technical references including the Subaru Legacy/Liberty 2015 Service Manual (Chassis: Front and Rear Suspension), the model runs a MacPherson strut front suspension and a double wishbone rear with separate shock absorbers. Aftermarket catalogues from KYB and Monroe also list complete front struts for BN/BS Legacy/Liberty, while the rear is shown as shocks only. So yes—struts are used on the front of the 2015 Subaru Legacy/Liberty, not the rear.

Up front, the struts do double duty. They’re the damper that controls bounce and also a key structural part of the suspension, supporting the coil spring and helping locate the wheel. That means they have a big say in ride comfort, steering feel, braking stability, and how evenly the tyres wear. Keep them healthy and the car feels tight and composed on Kiwi backroads and Aussie highways alike.

In normal use, quality struts can last a long while, but by around 80,000–150,000 kilometres many will be past their best—especially if the car sees rough roads, corrugations, or regular heavy loads. Telltales include clunks over bumps, a floaty or bouncy ride, nose-dive under braking, tramlining, uneven or cupped tyre wear, oily residue on the strut body, or the steering taking a moment to settle after turns.

When replacing, do both fronts together to keep handling balanced. An alignment is a must afterward because the strut position influences camber and toe. It’s smart to renew related hardware at the same time—top mounts and bearings, dust boots, bump stops, and any single-use (self-locking) nuts. If reusing coil springs, only compress them with proper spring compressors and stick to workshop torque specs. Many owners choose complete strut assemblies to save time and avoid spring handling.

Fresh struts can transform the Legacy/Liberty: cleaner turn-in, better mid-corner control, less brake dive, and quieter progress over sharp joins and potholes. And remember, while the rear of this model uses shocks (not struts), the front struts and rear shocks work together—tyres, alignment, and suspension bushes all play a part in the final ride and handling feel.

• Watch for leaks, knocks, or uneven tyre wear as early warning signs.
• Replace in pairs and book a wheel alignment immediately after.
• Consider complete assemblies for a quicker, cleaner job.

Popular questions about 2015 Subaru Legacy/Liberty struts

How often should the front struts be replaced?
There’s no fixed interval, but many see noticeable wear between 80,000 and 150,000 km depending on road conditions and load. If the ride feels floaty, the car dives under brakes, or the tyres wear oddly, it’s time for an inspection and likely replacement.

Do you need a wheel alignment after fitting new front struts?
Yes. Because the strut locates the wheel, changing it alters alignment angles. A professional alignment right after installation protects tyres, restores steering feel, and ensures the Legacy/Liberty tracks straight.

What’s the difference between the front struts and the rear shocks on this model?
The front uses MacPherson struts, which both damp and structurally locate the suspension. The rear uses separate shock absorbers in a double wishbone setup, so they damp movement but don’t act as a structural guide like a front strut does.
