Parts for your 2023 Mitsubishi Asx-Coil springs

2023 Mitsubishi ASX Coil Springs — What They Do and When to Replace

Coil springs are absolutely used on the 2023 Mitsubishi ASX. Technical sources from Mitsubishi confirm the ASX runs MacPherson strut front suspension and a multi-link rear, both employing coil springs to support the vehicle and control ride height (see Mitsubishi Motors Australia ASX model specifications and the ASX workshop/service manual suspension sections). That means coil springs are directly relevant to servicing and ownership for Australia and New Zealand models.

On the 2023 Mitsubishi ASX, the coil springs carry the vehicle’s weight, soak up bumps and help keep the tyres planted over rough roads. Working with the struts and shocks, they set ride height and play a big part in handling feel, steering response and braking stability. When the springs are healthy, the ASX feels composed and predictable, if they’re tired, it can sit low, feel floaty or bottom out over speed humps and corrugations.

There’s no strict replacement interval for coil springs, but regular checks during routine servicing are smart—especially if the ASX often carries passengers, luggage, or tows. A technician will look for chipped or missing paint exposing bare metal, corrosion (common in coastal areas), cracked coils (often near the ends), uneven ride height from side to side and any signs the spring has contacted the tyre or seat incorrectly. Unusual noises—clunks or twangs when turning or going over bumps—also warrant an inspection.

If replacement is needed, best practice is to fit springs in pairs on the same axle to keep the ride balanced. Matching the correct spring rate and free height to the vehicle’s exact variant (via VIN/build plate) avoids headaches like nose-up or tail-down stance. It’s a good time to refresh related parts too: strut mounts, bearings, insulators, seats, bump stops and dust boots. A wheel alignment is recommended after spring work to dial in camber and toe, protecting tyre life and restoring crisp steering.

• Never heat or cut springs—this weakens the steel and can make the ASX unsafe.
• Use proper spring compressors and torque fasteners at normal ride height to avoid bush preload.
• Lifted or lowered springs will change handling, headlight aim and potentially insurance/warranty—get professional advice and an alignment.

Look after the coil springs and the ASX will reward with a comfortable ride, confident cornering and even tyre wear across many kilometres of Aussie and Kiwi roads.

How long do coil springs last on a 2023 Mitsubishi ASX?

There’s no fixed lifespan, as it depends on loads, roads and climate. Many owners will never need springs during typical ownership, but frequent heavy loads, gravel driving and salty coastal air can hasten corrosion and fatigue. Get them inspected at each scheduled service and sooner if the ride height changes or the car starts to bottom out.

Do you need a wheel alignment after replacing ASX coil springs?

Yes—changing springs alters ride height and can nudge camber and toe. A post-replacement alignment helps the ASX track straight, keeps steering feel consistent and prevents premature tyre wear.

Is it safe to drive a 2023 ASX with a broken coil spring?

No. A broken spring can shift suddenly, affect steering or puncture a tyre. Park the vehicle and arrange a repair and tow if needed. Replace springs in axle pairs for balanced handling once it’s in the workshop.
