Parts for your 2025 Mazda 3-Strut mounts

2025 Mazda3 strut mounts: what they do and when to replace them

Technical sources confirm the 2025 Mazda3 uses MacPherson strut suspension at the front and a torsion beam at the rear, so front strut mounts are fitted and relevant, while the rear has no strut mounts. This layout is documented in the Mazda BP-series Workshop Manual (Front Suspension, MacPherson strut assembly and top mount/bearing), Mazda Australia’s model specification sheets noting “MacPherson strut (front), Torsion beam (rear)”, and major components catalogues from OE-equivalent suppliers listing front strut mounts for 2019-on BP Mazda3 vehicles, which carry through to MY2025.

On the 2025 Mazda3, the front strut mounts (often called top mounts) do more than just hold the strut in place. They isolate vibrations and road harshness from the body, keep the strut correctly located under load, and, crucially, house a bearing that lets the strut turn smoothly with the steering. When they’re healthy, the car feels quiet, direct and composed over bumps and during turn-in.

Because they’re rubber-and-bearing assemblies living under the bonnet, strut mounts cop heat, moisture and constant movement. Over time, the rubber can crack or compress and the bearing can develop play. Telltale signs include clunks over sharp bumps, a creak or pop when turning the wheel, vague steering, “memory steer” (the wheel not returning to centre cleanly), and uneven or cupped front tyres.

For servicing, it’s smart to have the strut mounts inspected whenever the front suspension or steering is checked, and definitely whenever front struts are replaced. In typical Australian and New Zealand conditions, many owners see reliable service life in the 80,000–120,000 km range, but city kerbs, coarse-chip roads, or heavier loads can shorten that. If one side fails or feels rough, replace mounts as a pair to keep steering feel even left to right.

Best practice during replacement includes: using quality OE-equivalent mounts with integrated bearings, renewing single-use nuts, correctly clocking the mount orientation, and torquing all fasteners to Mazda specifications. A wheel alignment should follow any front strut or mount work to protect tyres and restore crisp tracking. DIYers should only tackle this job with proper spring compressors and safety gear—there’s serious stored energy in the front coils. Otherwise, a trusted workshop can sort mounts and alignment in one visit, getting the Mazda3 back to its tidy, confidence-inspiring feel.

• Front: MacPherson strut with strut mount and bearing (fitted)
• Rear: Torsion beam with separate dampers (no strut mounts)

Popular questions about 2025 Mazda3 strut mounts

Does the 2025 Mazda3 have rear strut mounts?
No. The rear uses a torsion beam with separate shock absorbers, so there are no rear strut mounts on this model. Only the front suspension has strut mounts with integrated bearings.

How long do front strut mounts last on a 2025 Mazda3?
Many last 80,000–150,000 km, but life varies with road quality, driving style, and climate. Inspect them during routine servicing and replace them when noisy, notchy, cracked, or when fitting new front struts.

Can worn strut mounts affect alignment and steering feel?
Absolutely. Worn mounts can cause clunks, steering bind or “memory steer”, and inconsistent camber/caster under load, which may lead to feathered or cupped tyres. Replacing tired mounts and aligning the front end restores precision and tyre life.
