2020 Mitsubishi ASX Struts — What They Do and When to Replace Them

Yes, struts are relevant to the 2020 Mitsubishi ASX. Technical sources indicate the ASX uses MacPherson struts at the front and conventional shock absorbers at the rear.

• Mitsubishi ASX/RVR/Outlander Sport Workshop Manual: Front suspension specified as MacPherson strut.
• Mitsubishi ASA parts catalogue: Front strut assemblies listed for 2020 ASX, rear shows separate shock absorbers, not struts.
• Aftermarket catalogues (e.g., KYB, Monroe): Front listings are struts, rear listings are shocks for 2020 ASX.

The front struts on the 2020 Mitsubishi ASX do double duty. They’re not just dampers, they’re a structural part of the front suspension that carry the coil spring, tie the steering knuckle to the body, and keep alignment steady over bumps. That means they have a big say in how the ASX rides, steers, and stops, especially on corrugated country roads around Aus and NZ. A healthy set of struts helps the tyres keep consistent contact with the tarmac, trims body roll, and keeps braking distances predictable.

While struts aren’t a regular service item like oil or filters, they do wear. Many owners find that somewhere around 80,000–120,000 km, performance tails off, depending on road conditions and loads. Routine checks every 20,000 km as part of scheduled servicing are a smart move. Techs typically look for oil seepage from the strut body, damaged dust boots or bump stops, play or noise in the upper mounts/bearings, uneven tyre wear, and that tell-tale bouncy or floaty feel after bumps or on the open road.

When replacement time arrives, best practice is to do struts in pairs across the front. It’s also worth renewing the top mounts/bearings, boots, and bump stops at the same time to keep things quiet and tight. Because the strut locates the hub, a wheel alignment is essential after the job, camber and toe can shift even if everything was marked. Using OE-equivalent gas struts maintains the ASX’s original ride height and balance. If the vehicle sees a lot of gravel or towing, stepping up inspection frequency pays off.

Strut swaps involve compressing the front coil springs, so proper equipment and know-how matter. A competent workshop typically needs a couple of hours per side, and they’ll torque fasteners at ride height to avoid bushing preload. Done right, the ASX gets back that planted, tidy feel owners expect.

• Watch for: nose-dive under brakes, clunks over speed humps, steering shimmy, tramlining, and feathered or cupped tyre wear.
• Service tip: keep tyres correctly inflated and rotated, it helps struts and alignment do their best work.

Popular questions about 2020 Mitsubishi ASX struts

Does the 2020 ASX have struts or shocks?
The 2020 ASX runs MacPherson struts at the front and separate shock absorbers at the rear. That’s why front-end ride and steering feel change noticeably as the struts age, while the rear is handled by conventional dampers.

How often should ASX front struts be replaced?
There’s no fixed interval, but many are ready for replacement around 80,000–120,000 km. Road quality, loads, and driving style make a big difference. Regular inspections during servicing will catch leaks, worn mounts, or fading damping early.

Do struts need an alignment after replacement?
Yes. Because the strut locates the steering knuckle, replacing it can alter camber and toe. A proper wheel alignment after fitting new struts protects tyres and restores sharp steering.
