Parts for your 2017 Subaru Forester-Strut mounts

2017 Subaru Forester Strut Mounts

Based on technical references including the Subaru Forester (SJ) Service Manual for Front Suspension (MacPherson strut design identifying a “strut mount/insulator” with an integrated bearing) and Subaru’s published suspension layout for the SJ series (front MacPherson strut, rear double wishbone), strut mounts are indeed fitted to the front of the 2017 Subaru Forester. Aftermarket catalogues from major suppliers also list front strut top mounts for this model, reinforcing their use. The rear of the 2017 Forester uses separate shocks on a multi-link/double-wishbone setup, so there’s no rear MacPherson “strut mount” as such—just shock upper mounts.

On the 2017 Forester, the front strut mounts do more than simply hold the strut in place. They isolate road vibration and harshness, keep things quiet inside the cabin, and house a bearing that lets the strut rotate smoothly as the steering turns. When they’re tired, drivers may notice clunks over bumps, a creak when turning at low speeds, vague or wandering steering, and in some cases a bit of scalloping on the front tyres.

As part of routine servicing, it’s smart to ask for a look over the front strut mounts every 40,000–60,000 km or whenever the front struts are out. Many techs recommend replacing mounts at the same time as new struts or springs—doing both together saves labour and keeps the steering feel consistent. Always replace in pairs left/right, use new self-locking hardware, and book a wheel alignment afterwards. A proper alignment matters because a fresh mount can subtly alter ride height and camber.

Drivers who frequent corrugated roads, carry loads, or see a lot of city speed humps may notice earlier wear. If there’s a persistent knock you can’t chase down, a perished rubber insulator or a rough strut-top bearing is a usual suspect. During installation, correct bearing orientation and torque specs are critical, along with safely compressing the spring off the car. Expect roughly 1.5–2.5 hours per side in typical workshop conditions, give or take for corrosion and seized fasteners.

Quick note on the back end: the SJ’s rear is not a strut design, so while the shocks do have upper mounts, they’re not the same as a front MacPherson strut mount. Different part, different job.

• Common symptoms: clunks over bumps, steering creak, tramlining, uneven tyre wear.
• Good practice: replace in pairs, align afterwards, and use quality components.

Popular questions about 2017 Subaru Forester strut mounts

Does the 2017 Forester have rear strut mounts?

No. The rear suspension is a double-wishbone/multi-link arrangement with separate shock absorbers and coil springs. It uses shock upper mounts, not MacPherson strut mounts. The strut mounts you’ll be chasing live at the front.

How long do front strut mounts last, and when should they be replaced?

It’s common to see 80,000–150,000 km, but lifespan varies with road quality and load. Replace when there are noises, binding/roughness when turning, or visible rubber cracking—and any time you’re fitting new front struts, doing them together is smart.

Do new strut mounts affect wheel alignment?

Yes, they can. Fresh mounts can change ride height slightly and influence camber/caster. Always plan a wheel alignment after mount or strut replacement to keep tyre wear tidy and steering sweet.
