Parts for your 2017 Subaru Forester-Struts

2017 Subaru Forester struts: what they do and when to replace them

Based on technical sources, struts are absolutely relevant to the 2017 Subaru Forester. The Subaru Forester SJ (MY17) uses MacPherson struts at the front and a double-wishbone layout with separate shock absorbers at the rear. This configuration is confirmed by the Subaru Forester SJ (2017) Service Manual (Front Suspension section), Subaru Australia’s MY17 Forester specifications, and major suspension catalogues from KYB and Monroe that list front strut assemblies and rear shocks for this model.

On the front of a 2017 Forester, the MacPherson strut is a structural part of the suspension. It combines the shock absorber and coil spring in one unit, locates the wheel, supports the steering knuckle, and keeps the tyre in firm contact with the road. That’s what delivers the sure-footed feel in the wet, steadies the nose under braking, and takes the sting out of corrugations and potholes on Kiwi and Aussie roads.

As struts wear, damping fades and internal seals can weep oil. The result is extra bounce, longer stopping distances, and uneven tyre wear. While there’s no fixed replacement interval, a good rule of thumb is to have the struts checked from around 60,000–80,000 km, or sooner if the vehicle sees rough roads, towing, or heavy loads. Quality replacements (KYB is an OE supplier for Subaru) paired with fresh top mounts, bump stops, and dust boots will restore ride and handling nicely.

• Tell-tale signs: clunks over bumps, nose-diving, floaty rebound, cupped or scalloped tyres, oily strut bodies, steering shimmy, and longer braking distances.
• Best practice: replace front struts in pairs to keep handling balanced.
• Safety note: compressing coil springs is hazardous—use proper equipment or a trusted workshop.
• After fitment: get a full wheel alignment and reset steering angle if required, this protects tyres and ensures driver-assist systems behave correctly.
• Servicing tip: inspect at each service—look for leaks, torn boots, cracked mounts, and uneven tyre wear.

For owners chasing dependable ride quality and confident cornering, healthy front struts are non‑negotiable. Fresh units sharpen steering response, keep the Forester planted on broken surfaces, and help EyeSight-equipped models maintain predictable braking behaviour. Done properly—quality parts, correct torque, and alignment—the upgrade pays back in comfort, control, and tyre life.

Do all 2017 Foresters have struts on the rear as well?

No. The front uses MacPherson struts, while the rear is a double-wishbone setup with separate shock absorbers. People sometimes call rear dampers “struts”, but on this model they aren’t structural struts.

How long do front struts typically last on a 2017 Forester?

Anywhere from about 80,000 to 150,000 km depending on driving and load. Regular checks at service time are smart, especially if the vehicle tackles gravel, corrugations, or carries gear frequently.

Can a single worn strut be replaced on its own?

It can, but it’s not recommended. Replacing in pairs keeps damping balanced side-to-side. Always follow up with a wheel alignment to protect tyres and keep handling consistent.
