2017 Subaru Impreza Struts — What They Do and When to Replace

Based on technical references — including the Subaru Workshop Manual for the 2017MY Impreza (GK/GT), Subaru’s New Vehicle Features information for the Subaru Global Platform, and major suspension catalogues from KYB and Monroe — the 2017 Subaru Impreza uses MacPherson struts on the front axle and conventional shock absorbers with a multi-link/double-wishbone arrangement at the rear. So yes, “struts” are relevant to this model, specifically at the front.

On the front of the Impreza, the strut is the key structural piece that ties the wheel hub to the body. It combines a shock absorber and a coil spring into one assembly, supporting the vehicle’s weight, controlling body movement, and serving as a locating member for steering and alignment. That’s why worn front struts can show up as vague steering, extra dive under brakes, and uneven tyre wear.

For day-to-day motoring across Aussie and Kiwi roads, healthy front struts help the Impreza track straight, keep the tyres planted, and make the cabin feel settled over corrugations and potholes. Because they carry alignment angles, any slack in the strut, top mount, or bearing can shift camber and caster, nudging tyres out of spec and costing money at the pump and at tyre replacement time.

As part of routine servicing, it’s wise to have a quick suspension check every 10,000–15,000 km. A thorough inspection should look for oil misting on the strut body, cracked or collapsed top mounts, torn dust boots, and perished bump stops. If one front strut is shot, best practice is to replace struts in pairs to keep the car balanced.

• Typical signs the front struts need attention:
  • Clunks over sharp bumps or turning into driveways
  • Bouncy or floaty feel on country roads
  • Longer braking distances with extra nose-dive
  • Feathered or scalloped tyre wear at the front
  • Steering that won’t quite centre or feels nervous in crosswinds

After fitting new struts, a proper four-wheel alignment is essential. It resets camber and toe and makes sure the steering wheel sits straight. Consider renewing ancillary parts while you’re there — top mounts/bearings, dust boots, bump stops, and sway bar links — to avoid chasing squeaks later. Quality OE-equivalent struts matched to the Impreza’s spring rates will restore that tidy, confident feel owners expect, whether commuting in the city or heading off for a long weekend down the coast.

Q: How long do front struts last on a 2017 Subaru Impreza?

Service life varies with driving and road conditions, but many Impreza front struts will feel tired somewhere between 80,000 and 150,000 km. If the car regularly sees rough rural roads or carries heavy loads, expect wear closer to the lower end of that range. Go by condition, not just kilometres — any leaks, clunks or tyre wear patterns are reason to inspect.

Q: Do you need a wheel alignment after replacing front struts?

Absolutely. Because the strut is part of the steering geometry, changing it alters camber and toe. A post-fitment four-wheel alignment protects tyres, improves braking stability, and ensures the steering wheel sits straight.

Q: Can worn strut top mounts cause noise even if the damper isn’t leaking?

Yes. Top mounts and bearings can crack or bind, causing creaks or knocks at low speeds or when turning the wheel. It’s common to replace mounts, bearings, dust boots and bump stops along with the strut to keep the front end quiet and tight.
