Parts for your 2022 Mazda 3-Struts

2022 Mazda 3 struts: what’s fitted and how to look after them

Based on technical sources, the 2022 Mazda 3 (BP series) uses MacPherson struts on the front axle. The rear suspension is a torsion-beam with separate dampers (not struts), so “struts” are relevant to the front only on this model year.

• Technical sources referenced: Mazda BP Mazda3 Workshop Manual (Front Suspension: MacPherson Strut), Mazda global product information for the BP platform (MacPherson front, torsion-beam rear), OEM and aftermarket fitment catalogues (e.g., KYB/Monroe) listing front strut assemblies for 2022 Mazda 3, Mazda parts catalogue entries for front shock absorber/strut assemblies and top mounts.

The front struts on a 2022 Mazda 3 carry more than just ride comfort duties—they’re a structural part of the suspension that locates the wheel, supports the spring and keeps steering geometry in check. Each strut combines a shock absorber with a spring seat and top mount/bearing, so it soaks up bumps while holding camber and caster steady. When they’re healthy, the car feels planted, turns in neatly and wears tyres evenly—perfect for everyday Kiwi and Aussie roads, whether nipping to the shops or clocking up motorway kilometres.

Over time, internal valves and seals wear, or the shaft can pit, and that shows up as a floaty feel, nose-diving under brakes, knocky clunks over potholes or feathered tyre wear. A quick visual once-over at each service (or at least every 20,000 km/12 months) helps: look for oily seepage on the strut body, torn dust boots, split bump stops and cracked top mounts. If one front strut is shot, replace them as a pair so left-right damping stays balanced. It’s smart to bundle in new top mounts/bearings, bump stops and boots while it’s apart—the parts are affordable and the labour overlaps.

After fitting, a wheel alignment is highly recommended because the strut-to-knuckle relationship can nudge camber and toe. Use quality OE-equivalent units matched to the BP Mazda 3 and follow torque specs and nut/bolt reuse guidance from the workshop manual. The coil spring is under serious load, so only compress it with a proper spring compressor—no backyard shortcuts. Expect lifespan to vary with roads and loads, but many drivers see solid service well past 80,000–120,000 km. If the car feels unsettled, tramlines, or chews the inner shoulder of front tyres, get the struts, mounts and alignment checked—sorting them can transform the way the Mazda 3 steers and rides with no dramas.

• Does the 2022 Mazda 3 have rear struts?
  No. The rear uses a torsion-beam with separate shock absorbers, so there are no rear struts. Only the front axle runs MacPherson strut assemblies on this model.
• How often should front struts be replaced on a 2022 Mazda 3?
  There’s no hard expiry, but many owners replace between 80,000–120,000 km depending on roads and driving. Inspect annually for leaks, worn top mounts, clunks, or uneven tyre wear, and replace in pairs if performance drops.
• Do struts need a wheel alignment after replacement?
  Yes. Because the strut locates the steering knuckle, replacement can slightly shift camber and toe. A post-fit alignment helps protect tyre life and keeps the Mazda 3 tracking straight.
