Parts for your 2016 Subaru Impreza-Strut mounts

2016 Subaru Impreza strut-mounts — what they do and when to replace them

Based on technical references including the Subaru Factory Service Manual for the GP/GJ Impreza (2016 model year) and Subaru FAST parts catalogues, the 2016 Subaru Impreza runs a MacPherson strut front suspension, which uses front strut-mounts (often called “strut tops” or “top hats”). The rear is a double-wishbone layout with a separate shock and spring, so there isn’t a rear “strut-mount” in the strict sense—just a shock upper mount. That means strut-mounts are absolutely relevant at the front of this model.

On the front of the Impreza, the strut-mount does two big jobs. First, the rubber insulator isolates vibration and road noise from the body, keeping the cabin quiet and tidy over rough tarmac. Second, the bearing built into the mount lets the strut rotate smoothly as you steer, helping the wheel return to centre and keeping steering feel consistent. A healthy mount preserves alignment, reduces tyre chop, and protects the strut itself from shock loads.

For servicing, strut-mounts aren’t a fixed-interval item, but they’re worth a look every 20,000–30,000 km or at each major service. If the driver notices clunks over bumps, a creak or graunch when turning the wheel at low speed, vague steering, or uneven tyre wear, the mounts may be tired. On higher-kilometre cars, it’s smart to replace the mounts when fitting new front struts or springs, as labour overlaps and fresh mounts protect the new dampers.

• Inspect the rubber for cracks, separation, or perishing, check for bearing notchiness during steering.
• Replace in axle pairs to keep steering feel even side-to-side.
• Use quality OEM-equivalent mounts, observe mount orientation marks during assembly.
• Always get a wheel alignment after front strut-mount work.
• Consider renewing bump stops and dust boots at the same time.

Because the front coil spring must be compressed to change a strut-mount, this job needs proper tools and care. A competent mechanic can turn it around efficiently, DIYers should only attempt it with a quality spring compressor and workshop-grade safety practices. Treat the front strut-mounts well and the Impreza will steer sweetly, track straight, and stay quiet over Aussie and Kiwi roads.

Popular questions

Does the 2016 Impreza have rear strut-mounts?
No. The rear uses a double-wishbone setup with a separate shock and spring, so it has a shock upper mount rather than a true strut-mount. Only the front suspension uses strut-mounts on this model.

How long do front strut-mounts last on a 2016 Impreza?
Many last 100,000–150,000 km, but driving conditions matter. Lots of corrugations, potholes, or heavy loads can age the rubber and bearing sooner. If there are clunks, steering groans, or wandering, have them checked.

Should strut-mounts be replaced with the front struts?
It’s a good idea. Labour overlaps and new mounts protect fresh dampers, restore quietness, and sharpen steering return-to-centre. Most workshops recommend doing mounts, bump stops, and dust boots with new struts.
