Parts for your 2022 Mazda 3-Strut mounts

2022 Mazda 3 strut mounts — what they do and when to replace them

Strut mounts are very much relevant on the 2022 Mazda 3. Technical sources including the Mazda Workshop Manual for the BP-series Mazda3 (Front Suspension), Mazda Australia model specifications (2022), and major suspension catalogues from KYB and Monroe all confirm the car uses MacPherson struts at the front, which bolt to the body via dedicated strut top mounts incorporating a bearing. The rear uses a torsion-beam layout with separate dampers and springs, so there are no rear “strut” mounts.

On the front of a 2022 Mazda 3, the strut mount does two big jobs: it isolates bumps and road noise from the cabin, and it lets the strut turn smoothly as the wheels steer. The rubber insulator and the built-in bearing carry the car’s weight, cushion sharp hits, and keep steering feel consistent. When the mount is healthy, the car tracks straight, rides quietly, and the steering self-centres cleanly after a turn.

Over time, rubber can harden or crack, and bearings can get notchy. That’s when owners might notice clunks over small bumps, a dull thud on driveway entries, vague steering, or a “memory steer” feel where the wheel doesn’t return nicely to centre. Uneven front tyre wear and light front-end vibration are also common clues.

Good servicing practice is to inspect the front strut mounts whenever front dampers, springs, or top hats are removed—typically around 80,000–120,000 km, or sooner if the car lives with rough roads. Many workshops replace mounts in pairs when fitting new front struts, because labour overlaps and fresh mounts protect the new dampers. If a bearing feels gritty or there’s visible rubber cracking, replacement is cheap insurance for ride quality and alignment stability.

Replacement requires strut removal and safe spring compression, so it’s a job for a competent technician with the right gear. After any front-end suspension work, a wheel alignment is a must. Quality matters here—genuine Mazda, KYB, or Monroe mounts are well matched to the Mazda 3’s steering feel and NVH targets. Owners who hear clunks, feel stiffness on initial steering input, or notice feathering on the front tyres should get the mounts and front suspension checked promptly to avoid knock-on wear to other components.

• Typical lifespan: 80,000–150,000 km depending on roads and driving style.
• Replace in pairs and align afterwards.
• Listen for clunks, feel for notchy steering, and watch tyre wear.

Popular questions about 2022 Mazda 3 strut mounts

Do 2022 Mazda 3s have rear strut mounts?
No. The rear of the BP-series Mazda 3 uses a torsion-beam setup with separate shocks and springs, so there are no rear “struts” or rear strut mounts. Only the front uses MacPherson struts with strut top mounts and bearings.

How long do Mazda 3 strut mounts last?
In typical Aussie and Kiwi conditions, expect 80,000–150,000 km. Cars seeing rough roads, frequent kerb hits, or heavy loads may need them sooner. If you’re replacing front struts, it’s smart to do the mounts at the same time.

Can worn strut mounts cause steering issues or tyre wear?
Yes. A tired mount or binding bearing can cause clunks, vague or “sticky” steering, poor self‑centring, and front tyre feathering or inner-edge wear. Sorting the mounts and getting an alignment usually restores the Mazda 3’s tidy steering feel.
