Parts for your 2018 Mitsubishi Asx-Shock absorbers

2018 Mitsubishi ASX shock absorbers — what they do and when to replace them

Shock absorbers are absolutely fitted to the 2018 Mitsubishi ASX. According to Mitsubishi Motors’ service manual for the ASX/RVR/Outlander Sport (2018 MY, Suspension Group) and the Mitsubishi ASA parts catalogue, this model runs a MacPherson strut setup at the front (a shock absorber integrated into the strut) and a multi‑link rear with separate, gas‑pressurised shock absorbers. Aftermarket fitment data from major damper manufacturers also lists front struts and rear shocks specifically for the 2018 ASX. So yes—shocks are relevant, used and serviceable on this vehicle.

The job of the shock absorbers is to control spring movement, keeping the tyres planted, body motion tidy, and steering and braking nice and predictable. Good shocks help reduce nose‑dive under brakes, settle mid‑corner bumps, and stop the ASX pogoing along corrugations. They don’t hold the car up (that’s the springs), they damp the motion so the ride stays comfortable and the chassis stays in control.

There’s no fixed replacement interval, but it’s smart to have them inspected at every service or at least every 20,000 km. Many ASX owners find shocks are past their best somewhere around 80,000–120,000 km, sooner if the car sees rough roads, towing or heavy loads. Look for these clues:

• Oil weeping on the shock body or perished dust boots
• Excessive bounce, float, or clunks over bumps
• Uneven or cupped tyre wear and longer stopping distances
• More ABS/ASC intervention on bumpy braking zones

When replacement time rolls around, do fronts and rears in axle pairs to keep the handling balanced. On the front MacPherson struts, plan on new strut mounts/bearings and bump stops/dust boots, the spring needs proper compression tooling, so a competent workshop is the go. The rear shocks are simpler but still need correct support of the suspension arms and tightening to factory torque with the vehicle at normal ride height. A wheel alignment is recommended after front strut work (and often worthwhile after rear work on multi‑link cars) to keep tyre wear even and steering straight.

For best results, choose quality OE‑equivalent dampers rather than mixing brands or specs side to side. After installation, a road test over mixed surfaces will confirm the ASX tracks straight, rides calmly and brakes confidently.

How long do shock absorbers last on a 2018 Mitsubishi ASX?

In typical Aussie and Kiwi use, many last 80,000–120,000 km, but rough rural roads, loads and heat can shorten that. Regular inspections pick up leaks and worn mounts before they affect safety or tyres.

Do you need a wheel alignment after replacing ASX shocks?

Yes—after front strut work an alignment is strongly recommended. The rear multi‑link can also benefit to ensure the car tracks true and avoids premature tyre wear.

Is it safe to drive with worn shocks?

It’ll still move, but it’s not ideal. Stopping distances grow, stability systems work harder, and tyres wear faster. If there are leaks, clunks or floaty behaviour, it’s time to sort them.
