Parts for your 2020 Mitsubishi Asx-Strut mounts

2020 Mitsubishi ASX strut mounts

Based on technical sources, strut mounts are relevant and fitted to the front suspension of the 2020 Mitsubishi ASX. The Mitsubishi Motors Service Manual for the ASX/RVR/Outlander Sport (GA/GC series, Group 33: Front Suspension) specifies a MacPherson strut layout up front with an upper insulator and bearing assembly (commonly called the strut mount). Aftermarket application catalogues from suspension specialists such as KYB and Monroe also list front strut top mounts for 2010–2020 ASX models. The rear of the ASX uses separate shocks and springs, so rear strut mounts aren’t used.

On the 2020 ASX, the front strut mount ties the top of the strut into the body and carries steering loads via an integrated bearing. It cushions road harshness, keeps the strut located, and lets the strut rotate smoothly when the steering turns. When the rubber insulator fatigues or the bearing dries out, the driver may hear clunks over bumps, feel a notch or graunch in the steering, or notice vague front-end response and uneven tyre wear.

There isn’t a strict replacement interval, but it’s smart to have the strut mounts inspected at each major service or every 40,000–60,000 km, especially if the ASX regularly sees rough roads. Many owners replace the mounts whenever fitting new front struts or springs to keep everything tight and quiet.

• Common signs they’re tired: clunking or knocking over speed humps, a creak when turning the wheel at low speed, steering that won’t self-centre smoothly, and visible cracking or separation in the top mount rubber under the bonnet.
• Best-practice replacement: do both front mounts as a pair, renew the associated bearing (if separate), and consider new dust boots and bump stops at the same time. Follow torque specs from the Mitsubishi service manual and book a wheel alignment after the job.

For owners chasing a set-and-forget result, quality OEM-equivalent mounts are the go. If the ASX has been lowered or carries extra weight up front (bull bar, accessories), checking the mounts more often helps catch early wear. Keeping the under-bonnet area clean and addressing any strut top noises promptly will protect tyres and steering components, and keep the ASX riding and turning the way it should.

Popular questions about 2020 Mitsubishi ASX strut mounts

Do both front strut mounts need replacing at the same time?
It’s recommended to replace strut mounts in pairs. Wear is usually similar side to side, and doing both avoids uneven steering feel and reduces the chance of chasing new noises a few months later. A post-repair wheel alignment is also recommended.

How long do ASX strut mounts typically last?
Many see 80,000–150,000 km depending on road conditions and driving style. Lots of gravel or speed humps can shorten lifespan. There’s no hard interval, so regular inspection during services is the smartest approach.

What else should be replaced with the mounts?
When the front strut mounts are out, it’s efficient to assess and often replace the strut bearings (if separate), dust boots, bump stops and the upper spring seats. If the struts are worn or leaking, doing them at the same time saves labour and locks in a consistent ride and handling feel.
