Parts for your 2006 Mazda 3-Strut mounts

2006 Mazda 3 strut-mounts — what they do and when to replace

According to the Mazda3 (BK, 2003–2009) workshop manual and Mazda’s Electronic Parts Catalogue, plus suspension catalogues from KYB and Monroe, the 2006 Mazda 3 runs a MacPherson strut front end with upper strut-mounts that include a bearing plate. The rear uses separate shock absorbers and coils, so there are no rear strut-mounts. That means strut-mounts are absolutely relevant for the front of a 2006 Mazda 3.

Up front, the strut-mounts sit at the top of each strut, bolting the assembly to the body while isolating vibration and road harshness. The integrated bearing lets the strut turn smoothly as the driver steers, helping return-to-centre and keeping steering effort nice and light. Good mounts protect the body structure, preserve alignment, and keep cabin noise down, especially on coarse-chip or corrugated roads common across Australia and New Zealand.

Typical signs the 2006 Mazda 3 strut-mounts are on the way out include clunks over bumps, a creak or groan while turning the wheel at parking speeds, a slight knock on take-off/braking, or vague steering with tramlining. Uneven tyre wear on the shoulders can show up if the mount rubber has collapsed. During servicing, a quick visual check for perished rubber, cracked housings, or rusty, mushroomed tops is a smart move.

Replacement tips for this model:

• Change mounts in pairs on the front to keep steering feel even.
• Use OE-quality mounts with the bearing included, mixing old bearings with new rubber can leave a bind or squeak.
• Always book a wheel alignment afterwards, the strut position affects camber and caster.
• Inspect and replace related bits (bump stops, dust boots, top nut) while the strut is out.
• Expect lifespan anywhere from 80,000 to 150,000 km depending on roads, loads, and climate.

Because the front coils need compressing, the job calls for a proper spring compressor and torque specs from the workshop manual. If the strut spins while tightening or the spring isn’t seated correctly, it can cause noise or premature wear. Many owners bundle fresh front struts and top mounts together so everything settles in as a matched set and the alignment holds true for longer.

FAQs

Do all 2006 Mazda 3s have strut-mounts?
Yes — at the front. Every BK-series Mazda 3 uses front MacPherson struts with strut-mounts and bearings. The rear suspension is multi-link with separate shocks and springs, so no rear strut-mounts there.

How long do strut-mounts last, and should they be changed with the struts?
On Aussie and Kiwi roads, many last 80,000–150,000 km. It’s good practice to replace the mounts and bearings when fitting new front struts, then follow up with a wheel alignment for the best steering feel and tyre life.

What noises point to a failing strut-mount?
Listen for a clunk over potholes or speed humps, a creak when turning at low speed, or a notchy feel in the steering as the wheel passes centre. Any of these are a nudge to inspect the top mounts.
