Parts for your 2018 Toyota Avensis-Strut mounts

2018 Toyota Avensis strut mounts — purpose, service tips, and when to replace

Yes, the 2018 Toyota Avensis (T27 series) uses strut mounts. Technical documentation such as Toyota’s European Repair Manual for the Avensis T27 and the Toyota Electronic Parts Catalogue identify the front suspension as MacPherson strut with a “front suspension support sub‑assembly” (the strut mount) and an integrated bearing plate for steering rotation. Independent references like the Avensis T27 Haynes workshop manual describe the same layout. Rear suspension is multi‑link, so rear strut mounts aren’t applicable, but the front absolutely relies on strut mounts. That makes “2018toyotaavensis strutmounts” a relevant and common service item.

On this Avensis, the front strut mount’s job is to secure the top of the strut to the body, isolate noise, vibration and harshness, and provide a smooth bearing surface so the strut turns with the steering. When the rubber or bearing wears, owners may notice clunks over bumps, a dull thud on take‑off or braking, or notchiness at the steering wheel at parking speeds. Left too long, it can affect tyre wear and alignment.

During regular servicing, it’s smart to have the mounts checked whenever the front end is inspected—say every 20,000–30,000 kilometres, or if any new noises crop up. A tech will look for perished rubber, cracked housings, or play in the bearing while the suspension is unloaded. Because Aussie and Kiwi roads and climate can be tough on rubber, aging mounts around the 100,000–150,000 km mark aren’t unusual.

• Common signs: clunks over speed bumps, creaks on steering lock, wandering or tramlining, and feathered front tyres.
• Good practice: replace mounts and the separate top bearings together, in pairs (both fronts), and follow Toyota torque specs for the top nut and strut-to-knuckle bolts.
• After any strut or mount work: book a wheel alignment to set camber and toe back to spec.

Replacement typically involves removing the strut, safely compressing the spring, transferring the spring and seat to the new mount, then refitting. It’s not a DIY job for most driveways—spring compressors and correct torque procedures are essential. While in there, it’s worth checking the strut bearings, dust boots, and bump stops, and considering fresh strut cartridges if they’re weeping or tired. Quality OEM or reputable aftermarket mounts will keep the Avensis quiet, compliant, and precise at the wheel.

There’s no ongoing lubrication or adjustment needed for strut mounts, but keeping cowl drains clear to reduce water ingress and avoiding kerb hits will help them last. If the front end starts chatting back over bumps, that’s the cue to get the mounts inspected sooner rather than later.

• Does the 2018 Toyota Avensis definitely have front strut mounts?
  Yes. Factory service literature for the T27 Avensis specifies a MacPherson strut front end with an upper “support” (strut mount) and separate bearing. Toyota’s parts catalogue lists these components for 2018 models, and independent manuals mirror that layout.
• What mileage do Avensis strut mounts usually last?
  There’s no fixed interval, as life depends on roads and loads. Many last well past 100,000 km, but in Australia and New Zealand it’s common to assess condition around 100,000–150,000 km or sooner if symptoms appear. Replace on condition, not just kilometres.
• Do strut mounts need replacing in pairs, and is an alignment required?
  Best practice is to replace both front mounts together so ride height, steering feel, and noise isolation are even side to side. After any strut or mount work, a wheel alignment is strongly recommended.
