Parts for your 2016 Subaru Legacy-Strut mounts

2016 Subaru Legacy strut mounts: what they do and when to replace them

Based on technical references including the Subaru Factory Service Manual for the 2015–2018 Legacy/Outback (Chassis – Front Suspension), Subaru service training material on MacPherson front suspension, and OEM parts catalogues that list a front “strut mount/insulator with bearing” for BN/BS Legacy, the 2016 Subaru Legacy absolutely uses strut mounts at the front. The rear uses a double-wishbone arrangement with a separate shock and a rear upper shock mount, not a strut mount.

On the 2016 Legacy, the front strut mount sits at the top of each MacPherson strut. It’s a rubber-insulated mount with an integrated bearing, letting the strut rotate smoothly as the steering turns while isolating road harshness from the body. That combo keeps steering light and precise while soaking up bumps, cutting down on vibration and tyre noise coming up into the cabin.

Because the mount carries vehicle weight and copes with every steering input, it’s a wear item. As the rubber hardens or cracks and the bearing wears, owners may notice clunks over speed humps, a creak when turning at low speed, or woolly on-centre steering feel. Left too long, it can accelerate tyre wear and make alignment harder to keep in spec.

As part of routine servicing for a 2016 Subaru Legacy, a quick inspection of the front strut mounts is smart every 20,000–30,000 km, or any time the car’s up for tyres, brakes, or an alignment. Look for perished rubber, split dust seals, witness marks from top-hat movement, or play/noise in the bearing when the strut is unloaded. There’s no greasing or adjustment—when worn, replacement is the go.

• Typical replacement triggers: steering knock or creak, abnormal tyre wear, poor return-to-centre, visible rubber cracking, or during strut replacement.
• Best practice: replace mounts in pairs, fit new nuts where specified, and follow the workshop manual for spring compression and torque procedures.
• Always finish with a four-wheel alignment, strut removal disturbs camber/caster settings.

Quality mounts bring back quiet operation and crisp steering, especially noticeable on coarse-chip roads common around Aus and NZ. For cars doing higher kilometres or carrying loads, pairing fresh strut mounts with new struts and bearings restores the front end to factory feel and helps tyres wear evenly.

Do all 2016 Subaru Legacy models have front strut mounts?

Yes. All 2016 Legacy variants run MacPherson struts at the front, so they use front strut mounts with an integrated bearing. The rear is a separate shock on a double-wishbone, which uses a shock upper mount rather than a strut mount.

How long do front strut mounts typically last on a 2016 Legacy?

It varies with roads and driving. Many last 100,000–160,000 km, but cars seeing rougher surfaces or lots of urban kerb hops can wear them sooner. Inspect them at service, and consider replacement when fitting new front struts to avoid doing the job twice.

What are the tell-tale signs the strut mounts are on the way out?

Common signs include a knock over potholes, a creak when turning the wheel at parking speeds, vague steering feel, or feathered/uneven front tyre wear. Visible cracking in the rubber or play felt at the top of the strut with the suspension unloaded are also red flags.
