Parts for your 2018 Mitsubishi Outlander-Coil springs

2018 Mitsubishi Outlander coil springs — what they do and when to replace them

Coil springs are absolutely fitted to the 2018 Mitsubishi Outlander. Technical references including the Mitsubishi Outlander Workshop/Service Manual (suspension sections for ZK/ZL series) and Mitsubishi Motors specification guides list a MacPherson strut front end with coil springs and a multi-link rear suspension also using coil springs. Industry databases used by workshops across Australia and New Zealand echo the same setup for petrol, diesel and PHEV variants.

On this Outlander, the coil springs carry the vehicle’s weight, set the ride height and soak up bumps before the shocks/struts control the motion. They’re central to comfort and handling, keeping tyres planted and the body level under braking, cornering and when loaded up for a family road trip. A healthy set of coils helps the Outlander track straight, protect the shocks and bushings, and maintain the correct headlight aim and ADAS sensor geometry.

There’s no fixed replacement interval for coil springs, but they should be inspected at every service. Look for broken ends, cracked coils, flaking paint, heavy rust (especially in coastal areas), and a sagging stance side-to-side or front-to-rear. If replacement is needed, best practice is to change springs in axle pairs to keep balance and consistent ride height. It’s also smart to renew related hardware such as upper strut mounts, isolators, insulators, seats, bump stops and dust boots, then finish with a four-wheel alignment. Matching spring rates to the vehicle spec (including PHEV battery weight or tow package) avoids odd ride heights and uneven tyre wear.

• Common signs the Outlander’s coil springs need attention:
  • Clunks, twangs or creaks over speed humps or driveways
  • Noticeable lean or a “nose-down/tail-down” look
  • Harsh, bouncy or floaty ride, bottoming out with passengers or cargo
  • Uneven tyre wear or repeated alignment drift

Owners who tow, run roof loads or tackle rough country roads may see earlier fatigue, heavy-duty or towing-rated coils can help. Because springs are under serious tension, removal needs the right compressor and technique—this is a job for a qualified tech. Keeping corrosion at bay and avoiding makeshift spacers or clamps will protect the Outlander’s ride, handling and safety, and keep it sweet for the next WOF or rego check.

FAQs

How long do coil springs last on a 2018 Outlander?
In normal Aussie and Kiwi driving, many coils last well past 150,000 km, but lifespan depends on loads, road conditions and corrosion. Regular inspections are the key—replace at the first sign of damage or sag so shocks and tyres aren’t put under extra stress.

Do coil springs need to be replaced in pairs, and is an alignment required?
Yes—replace both fronts or both rears together to maintain balance and consistent ride height. A wheel alignment is recommended after spring or strut work to protect tyres and ensure the Outlander steers and tracks properly.

Are aftermarket “lift” or heavy‑duty springs OK for the Outlander?
They can be, provided the spring rate and height suit the specific model (including PHEV) and intended use, and they comply with local regulations. Expect changes in ride and handling, pairing with matched dampers often gives the best result.
