Parts for your 2018 Subaru Outback-Strut mounts

2018 Subaru Outback strut mounts — yes, they’re fitted up front

Based on technical references, strut mounts are indeed used on the 2018 Subaru Outback (BS series) at the front suspension. The Subaru Service Manual for the 2018 Outback specifies a MacPherson strut front setup with an upper support (strut top mount and bearing), while the rear uses a separate shock and coil spring on a multi-link layout. Subaru’s parts catalogue lists a front strut mount assembly for this model, and major suspension catalogues from brands commonly used in AU/NZ also range replacement front top mounts for 2015–2019 Outback. So, strut mounts are relevant for the front axle of this vehicle.

On the Outback, the front strut mount (often called the strut top) does a few big jobs. It ties the strut into the body, takes the load of bumps and braking, isolates noise and vibration with a rubber insulator, and lets the strut rotate smoothly when steering via an integrated bearing. When these mounts age or the bearing dries out, the driver can cop clunks over potholes, groans when turning, vague steering feel, or cupped tyre wear.

For servicing, it’s smart to have the strut mounts inspected whenever the front suspension is apart, or every 20,000–30,000 km during routine checks. In Aussie and Kiwi conditions, many owners see reliable service past 80,000 km, but rough roads, towing, or heavy loads can bring that forward. Most workshops will recommend replacing the mounts whenever new front struts are fitted, as pairing fresh dampers with tired tops can leave noise or steering feel issues on the table.

• Typical symptoms to watch: knocking over sharp bumps, a creak or click while turning at low speed, heavier-than-normal steering return, and visible cracks in the rubber around the top mount.
• Best practice: replace mounts in pairs on the front axle, use quality units with the correct bearing, torque everything at ride height, and book a wheel alignment straight after. Steering angle reset may be required on some scan tools.
• Note: the rear of the 2018 Outback doesn’t use a MacPherson strut, so it doesn’t have rear “strut mounts” in the same sense—just upper shock mounts.

Popular questions about 2018 Subaru Outback strut mounts

Do the rear suspension components have strut mounts on a 2018 Outback?
No. The rear is a multi-link layout with a separate shock and spring, so there’s an upper shock mount rather than a MacPherson-style strut mount. The term “strut mount” on this model refers to the front only.

How long do front strut mounts typically last in AU/NZ conditions?
Many will run 80,000–150,000 km, but lifespan swings with road quality, load, and driving style. If there are clunks, steering groans, or tyre wear patterns, it’s worth inspecting sooner.

Do I need a wheel alignment after replacing front strut mounts?
Yes. Removing the strut assembly disturbs camber and caster. A proper alignment—and steering angle calibration if required—protects tyre life and keeps the Outback tracking straight.
