Parts for your 2018 Mazda Cx-5-Coil springs

2018 Mazda CX-5 coil springs — what they do and when to replace them

Coil springs are absolutely relevant and fitted on the 2018 Mazda CX-5 (KF series). Technical references, including the Mazda workshop manual and Mazda Genuine Parts catalogues, specify a MacPherson strut front suspension with coil springs and a multi-link rear suspension, also with coil springs, across FWD and AWD variants, petrol and diesel.

On this model, the coil springs carry vehicle weight, set ride height, and work with the shocks/struts to keep the tyres planted. That’s what delivers the CX-5’s settled, confident ride and tidy handling in everyday commuting and on longer trips. The spring rates are tuned so the SUV feels composed over corrugations and quick to recover after bumps, while still remaining comfortable for passengers.

There’s no fixed replacement interval for coil springs, but they’re a wear item. During routine servicing of a 2018 CX-5, a visual inspection should check for cracked coils, chipped powder-coat, rust pitting (especially near the bottom coils), broken pigtails, collapsed or perished spring seats/insulators, and uneven ride height side-to-side. Any of these findings calls for replacement.

• Common symptoms of tired or damaged coil springs:
  • Knocks or creaks over bumps, or a “twang” noise when steering
  • Nose-diving under brakes or excessive squat when loaded
  • Uneven tyre wear or a noticeable lean
  • Reduced ground clearance compared with spec

Best practice on this CX-5 is to replace coil springs in axle pairs to keep balance and ride height even. An alignment should follow any spring or strut change. It’s also smart to inspect related parts at the same time: struts/shocks, top mounts/bearings, bump stops and dust boots. If the vehicle regularly tows, carries gear, or runs accessory weight, consider load-rated or heavy-duty springs that suit those conditions.

Service technicians typically check coil springs every 10,000–15,000 kilometres or annually. Road salt near the coast and gravel road use can accelerate coating damage and corrosion, so a rinse of the underbody now and then helps. Because coil springs store significant energy, removal/installation requires a proper spring compressor and safe workshop procedure—this is one job best left to qualified professionals if there’s any doubt.

When maintained and matched with healthy dampers, the CX-5’s coil springs help the SUV drive the way Mazda intended: quiet, controlled and confidence-inspiring on Aussie and Kiwi roads.

FAQs

Do all 2018 Mazda CX-5 models use coil springs?

Yes. Every 2018 CX-5 (KF) variant—FWD or AWD, petrol or diesel—uses front MacPherson struts with coil springs and a rear multi-link with coil springs, as specified in Mazda workshop and parts literature.

How long do coil springs last on a 2018 CX-5?

There’s no set lifespan, but many last well over 150,000–250,000 kilometres. Harsh roads, heavy loads and coastal corrosion can shorten that. Replace if there’s cracking, broken coils, sagging ride height, or persistent noises.

Should coil springs be replaced in pairs, and is an alignment needed?

Replacing in axle pairs is recommended to keep ride height and handling consistent. After any spring or strut work, a wheel alignment is advisable to restore correct geometry and tyre wear.
