Strut-mounts for the 2021 Mitsubishi ASX

Technical sources confirm the 2021 Mitsubishi ASX does use strut-mounts. The Mitsubishi Motors ASX/RVR workshop manual for the GA-series (2019–2021) specifies a MacPherson strut front suspension that includes an upper strut mount/insulator. Major parts catalogues used in Australia and New Zealand from brands like KYB and Monroe list front strut-mount kits for ASX models from 2010 through 2022, further verifying fitment on the 2021 ASX.

On the 2021 ASX, the front strut-mounts do an important job. They secure the top of each MacPherson strut to the body under the bonnet, isolate road vibration and noise with a rubber insulator, and allow the strut to rotate smoothly as the steering turns via an integrated bearing. That combo keeps steering light and precise while filtering out harshness so the cabin stays quiet and comfy on Aussie and Kiwi roads.

Because strut-mounts cop loads from bumps, corrugations, kerbs and steering inputs, they wear over time. The rubber can crack or compress, and the bearing can dry out or bind. While there’s no fixed kilometre interval, it’s smart to have them checked at regular services and any time the front end is apart. If replacing front struts on a 2021 ASX, doing new strut-mounts and bearings at the same time saves on labour and helps the new shocks perform their best.

• Common signs a strut-mount is tired: clunks or knocks over speed humps, creaks when turning the wheel at low speed, vague or heavy steering feel, poor self-centring, or feathered/uneven front tyre wear.
• Good service habits: inspect the upper mounts and bearings during routine servicing, especially from higher kilometres or after plenty of rough-road driving, replace mounts in axle pairs, and get a wheel alignment after any strut or strut-mount work.

Quality replacement strut-mounts restore quiet operation and steering smoothness on the ASX, and they help protect new struts from premature wear. A workshop that knows the platform will torque fasteners correctly, seat the spring properly in the perch, and verify the bearing rotates freely before refitting. That attention to detail keeps the ASX tracking straight, turning sweetly, and riding the way Mitsubishi intended.

Popular questions about 2021 Mitsubishi ASX strut-mounts

Does the 2021 Mitsubishi ASX use strut-mounts?
Yes. The factory front suspension is MacPherson strut, which requires an upper strut-mount/insulator with a bearing. This is documented in Mitsubishi’s GA-series workshop information and reflected in AU/NZ aftermarket catalogues listing front strut-mount kits for the ASX.

When should ASX strut-mounts be replaced?
There’s no strict kilometre interval. Replace them if there are noises (clunks/creaks), steering notchiness or heaviness, visible rubber cracking, or during front strut replacement. Many last well past 100,000 km, but rough roads and heavy loads can shorten their life.

Do you need a wheel alignment after changing strut-mounts?
Absolutely. Any time the front struts or strut-mounts are disturbed, a wheel alignment is recommended to keep tyre wear even and steering feel spot on.
