Parts for your 2016 Mazda Cx-9-Strut mounts

2016 Mazda CX-9 strut mounts

Based on technical references, strut mounts are fitted to the 2016 Mazda CX-9. The Mazda workshop manual for the TC-series CX-9 specifies a MacPherson strut front suspension, which uses a top strut mount with an integrated bearing at the body tower. Mazda’s Electronic Parts Catalogue (EPC) also lists a front shock/strut top mount (insulator) for this model, and major aftermarket catalogues carry front strut mount kits for the 2016 CX-9. The rear is a multi-link arrangement with separate shock absorbers, so “strut mounts” apply to the front only.

On the CX-9, the front strut mounts do a few key jobs: they secure the strut to the body, isolate road harshness and noise with a rubber insulator, and—thanks to the built-in bearing—let the strut smoothly rotate as the wheels steer. That little bearing pack is what stops the spring from winding up and releasing with a twang as the steering turns. Good mounts help keep alignment stable, reduce vibration through the cabin, and make the steering feel consistent and light.

As they age, the rubber can crack or compress, and the bearing can dry out or seize. That shows up as clunks over bumps, a notchy or heavy feel when turning at parking speeds, a “memory steer” where the wheel doesn’t self-centre nicely, and sometimes uneven tyre wear at the front. If left too long, worn mounts can accelerate wear of the struts and top hats, and upset camber/caster just enough to make the CX-9 wander on the motorway.

For servicing, a practical approach in AU/NZ conditions is to inspect the front strut mounts from around 60,000–80,000 km and then at each major service. Many owners end up replacing them between 100,000 and 150,000 km, or whenever the front struts are renewed. They’re best done in pairs. Use OE or reputable aftermarket mounts, orient the mount correctly (there are index marks), and torque all fasteners to the Mazda spec. A wheel alignment is recommended after any strut or mount work. If using a spring compressor, take proper safety precautions, or consider complete loaded strut assemblies to reduce risk and workshop time. Given our hotter climates and rougher back roads, fresh mounts can noticeably tighten up the CX-9’s steering feel and reduce NVH.

• Common signs: clunks or creaks over speed humps, notchy steering at low speed, steering that won’t return to centre, front-end vibration, or visible cracking at the top mount.
• Service tips: replace in pairs, check upper spring seats and dust boots, and finish with a quality alignment to protect your tyres.

Does the 2016 Mazda CX-9 have strut mounts?

Yes—at the front. The TC-series CX-9 runs MacPherson struts up front, which use a strut mount and bearing. The rear is multi-link with separate shocks, so “strut mounts” don’t apply at the back.

How often should front strut mounts be replaced?

There isn’t a strict interval. Inspect from around 60,000–80,000 km and replace when there are symptoms or when fitting new front struts—commonly somewhere between 100,000 and 150,000 km depending on roads, load, and climate.

Do strut mounts affect alignment and steering feel?

Absolutely. Worn mounts can alter camber/caster slightly and cause memory steer or a notchy feel. After replacing mounts or struts, a wheel alignment is recommended to keep the CX-9 tracking straight and to protect tyre life.
