Parts for your 2015 Mitsubishi Asx-Struts

2015 Mitsubishi ASX struts — what they do and when to replace them

Yes, the 2015 Mitsubishi ASX is fitted with front MacPherson struts. Technical sources including the Mitsubishi ASX/RVR/Outlander Sport workshop manual (2010–2017), Mitsubishi Motors Australia specification sheets, and aftermarket catalogues from KYB and Monroe all list a MacPherson strut front suspension for this model. At the rear, the ASX uses a multi-link arrangement with separate coil springs and shock absorbers, not struts.

Up front, the struts do double duty: they act as dampers to control bounce and a structural component that locates the hub and carries vehicle weight. That’s why they have a big say in how the ASX steers, brakes, and rides on Aussie and Kiwi roads. Fresh struts help the tyres stay planted, keep steering precise, and support consistent braking distances in the wet.

Over time, internal valves wear, seals age, and the top mounts can develop play. On a 2015 ASX that’s done a fair few kilometres, tell-tales include front-end floatiness over corrugations, a thud on sharp bumps, nose-diving under brakes, vague steering, and uneven tyre wear. Many owners see the best performance from new struts every 80,000–150,000 km depending on road conditions and loads, but inspection during each service is the smart play.

When it’s time, technicians usually replace struts in axle pairs and fit new top mounts/bearings, bump stops, and dust boots. The springs can often be reused if they’re sound, but any rusting or sagging is a prompt to change them. After installation the vehicle should be settled at ride height before final torque and a wheel alignment is essential to restore camber and toe. Using OE-quality units matched to the ASX keeps ride height correct and avoids odd handling.

A quick check schedule that suits local conditions:

• Inspect for leaks, dented housings, split boots, and loose mounts at every service.
• Road test for steering shimmy, bounce, and brake dive, compare left to right response.
• Rotate tyres and check wear patterns, feathering or cupping can point to tired struts.
• Book an alignment after any suspension work or serious pothole strike.

Remember, the rear of the 2015 ASX uses shock absorbers rather than struts, so front and rear components differ. Keeping both ends healthy delivers the confident, tidy handling drivers expect from their ASX.

FAQs

Does the 2015 Mitsubishi ASX have struts front and rear?

No. It has MacPherson struts at the front. The rear uses a multi-link layout with separate shock absorbers and coil springs. That’s why front and rear parts aren’t interchangeable and have different service procedures.

How often should ASX struts be replaced?

There’s no fixed expiry, but many see best results replacing between 80,000 and 150,000 km, depending on road quality and loads. Have them inspected at every service for leaks, worn mounts, and ride control issues, and replace in pairs with a wheel alignment.

Can worn struts cause a WOF/roadworthy fail?

They can, if they’re leaking, loose, or no longer controlling rebound properly. Aside from safety concerns, worn struts can cause uneven tyre wear and longer stopping distances. If there’s any doubt after inspection, it’s worth sorting before the next check.
