Parts for your 2012 Toyota Avensis-Struts

2012 Toyota Avensis struts — what they do and when to replace them

Based on technical references including the Toyota Avensis (T27) Repair Manual, Toyota Electronic Parts Catalogue, the Haynes workshop manual for 2009–2015 models, and KYB/Monroe aftermarket catalogues, the 2012 Toyota Avensis is fitted with MacPherson struts on the front axle. The rear uses separate shock absorbers with coil springs, not rear struts.

On the front, the strut does double duty: it’s both the shock absorber and a key structural bit that locates the wheel and keeps alignment steady. It supports the spring, damps bumps and braking dive, and—through the top mount and bearing—lets the front end steer smoothly. Healthy struts keep the Avensis feeling planted, protect tyres from cupping, and help the ABS and stability control do their job on wet Kiwi and Aussie roads.

There’s no fixed replacement interval, but a good rule is to have the front struts inspected at regular services (every 10,000–15,000 km) and expect replacement somewhere in the 80,000–120,000 km range, sooner if it spends its life on rough chipseal or corrugated country roads. Any WOF or rego inspection noting leaks or poor damping is a prompt to act.

• Tell-tale signs: oily film or obvious leaks on the strut body, knocking over bumps, vague steering or tramlining, nose-diving under brakes, longer stopping distances, uneven or scalloped tyre wear, the bonnet bounce test failing to settle quickly.
• Best practice: replace struts in axle pairs, fit new top mounts/bearings, bump stops and dust boots, torque mounts with the suspension at normal ride height, finish with a proper wheel alignment.
• Safety note: the front coil spring stores serious energy—use a quality spring compressor or have a pro handle the swap.

When budgeting, quality OE-equivalent gas struts are worth it for ride and braking stability. After replacement, the Avensis should steer more cleanly, track straight, and wear its tyres evenly. The rear dampers are a different design but deserve the same periodic checks for leaks and fade, especially if the car tows or carries loads.

Does the 2012 Avensis have struts front and rear?

It runs MacPherson struts at the front. The rear uses separate shocks with coil springs (not struts), across sedan and wagon variants in this generation. So “front struts, rear shocks” is the correct setup.

How often should front struts be replaced?

There’s no strict schedule. Have them checked at each service, many owners see replacement between 80,000 and 120,000 km depending on road conditions and loads. Any leaks, clunks, poor control, or uneven tyre wear mean it’s time.

Do you need a wheel alignment after fitting struts?

Yes. Because the strut locates the hub, changing it can shift camber and toe. A post-fit alignment brings steering back on centre, protects tyres, and keeps safety systems happy.
