Parts for your 2015 Mitsubishi Outlander-Coil springs

2015 Mitsubishi Outlander coil springs — what they do and when to replace them

Coil springs are absolutely relevant to the 2015 Mitsubishi Outlander. Technical references including the Mitsubishi Outlander 2015 Owner’s Manual (Chassis section), the Mitsubishi Workshop Manual Group 60—Suspension, and AU/NZ dealer spec sheets indicate the model uses a MacPherson strut front suspension with coil springs and a multi-link rear suspension with coil springs across petrol, diesel, and PHEV variants.

On a 2015 Outlander, the coil springs carry the vehicle’s weight, control ride height, and work with the shocks/struts to keep tyres planted and the cabin composed over rough roads. They’re the unsung heroes that help the SUV soak up corrugations, speed bumps, and potholes, while keeping braking and cornering predictable. When the springs are healthy, the Outlander feels settled and tracks straight, when they’re tired or broken, it can sit low on one corner, bottom out over bumps, or feel skittish.

During routine servicing, it’s smart to have the springs inspected along with the struts/shocks. A tech will look for chipped or flaking paint on the coils (a sign corrosion is taking hold), cracks—often near the ends of the spring—uneven ride height, or coils that are contacting each other. Any broken or badly corroded spring should be replaced straight away, and always in axle pairs to keep the handling balanced. It’s also worth checking related hardware: top mounts, rubber isolators, bump stops, and the stabiliser links and bushes.

There’s no strict replacement interval for coil springs, many last well over 150,000 km. That said, coastal living, gravel roads, heavy towing, or constant loads can age them faster. Typical symptoms that say it’s time:

• Clunks, knocks, or a metallic ping from a corner over bumps
• Nose-diving under brakes or sagging tail when loaded
• Uneven or reduced ride height, tyre rub on big bumps
• Visible cracks, heavy rust, or broken end coils

When replacing, a proper spring compressor and the right procedures are non-negotiable—this isn’t a DIY job without the correct gear. After new springs (and any struts/shocks) go in, a wheel alignment is recommended to protect tyres and keep steering true. Avoid heating or cutting springs, it weakens the steel and is unsafe. Quality, model-correct springs restore the Outlander’s ride height and comfort, making long Kiwi or Aussie road trips a breeze again.

Do all 2015 Mitsubishi Outlanders have coil springs?

Yes. Technical specs for AU/NZ models show a front MacPherson strut with coil spring and a rear multi-link with coil springs on petrol, diesel, and PHEV variants. There are no leaf or air spring options from factory for this model year.

How long do the coil springs typically last?

Many go well past 150,000 km, but coastal environments, unsealed roads, and heavy loads can shorten their life. Include a visual check at each service, and replace in axle pairs if any damage, sagging, or breakage is found.

Should coil springs be replaced with the shocks/struts?

They don’t have to be replaced together every time, but it’s common to fit new springs when installing new struts/shocks if there’s wear, corrosion, or a ride-height concern. Doing both can restore comfort and handling in one go.
