Parts for your 2017 Mitsubishi Asx-Strut mounts

2017 Mitsubishi ASX strut mounts — what they do and when to replace them

Strut mounts are absolutely fitted to the front of the 2017 Mitsubishi ASX. The ASX runs a MacPherson strut front suspension, which uses an upper strut mount with an integrated bearing to support the strut and allow the strut to rotate as the wheels steer. The rear is a multi-link setup (not a strut), so rear “strut mounts” aren’t used in the same way. This configuration is confirmed by Mitsubishi’s service literature and widely used parts catalogues.

Up front, the strut mount sits at the top of the strut assembly, insulating road noise and vibration while also acting as the turning pivot for the strut. Inside the mount is a bearing that lets the spring and strut rotate smoothly with the steering. When the rubber isolator or bearing wears, the ASX can develop clunks over bumps, notchy or springy steering feel when parking, tyre feathering, or a subtle change in ride height at one corner.

Servicing advice is straightforward. During routine services, a quick inspection for perished rubber, cracked housings, or rusty/distorted top plates is worthwhile, especially from about 60,000–90,000 km or if the vehicle sees rough roads. If replacing front struts or springs, it’s smart to replace the strut mounts and bearings at the same time — the labour overlaps and it helps reset the front end for consistent steering feel and quiet operation.

Replacement tips a workshop would follow:

• Replace in pairs (left and right) to maintain even steering and ride quality.
• Use a quality spring compressor and torque the top nut and mount fasteners to spec.
• Check the bearing turns freely with no grittiness before reassembly.
• Book a wheel alignment after refit to protect tyres and restore straight-ahead feel.

While strut mounts don’t have a fixed change interval, many ASX owners see best results replacing mounts with the first major front suspension refresh, typically somewhere between 100,000 and 150,000 km, earlier if there’s noise or steering notchiness. Doing them once, properly, with new top nuts and any required dust boots or spring seats keeps the front end quiet and the steering light and precise — exactly how an ASX should feel around town or on a long Kiwi or Aussie road trip.

Technical sources referenced:

• Mitsubishi Motors Service Manual, ASX/Outlander Sport (GA models), Group 33 Front Suspension — specifies MacPherson strut with upper support/bearing.
• Mitsubishi global parts catalogues for GA-series ASX — list front strut upper mount/insulator assemblies for MY17.
• Aftermarket fitment guides (e.g., KYB and Monroe) — catalogue dedicated front strut mount kits for 2017 Mitsubishi ASX.

Are strut mounts fitted to the rear of a 2017 ASX?

No. The rear uses a multi-link layout with separate components, so there’s no rear MacPherson strut mount. Any rear top mounts you’ll hear about are for shocks, not struts, and are a different design.

What are the common signs the front strut mounts need replacing?

Clunks over speed bumps or driveway entries, notchy steering at parking speeds, a twang or creak as you turn the wheel, and uneven or feathered front tyre wear are the big tell-tales. If in doubt, have a technician check for play and binding in the mount bearing.

Do strut mounts need an alignment after replacement?

Yes. Any time the front strut assemblies are disturbed, a wheel alignment is recommended to set camber and toe correctly. It protects your tyres and keeps the ASX tracking straight.
