Parts for your 2018 Toyota Avensis-Strut mounts

2018 Toyota Avensis strut mounts

Strut mounts are absolutely relevant on the 2018 Toyota Avensis (T27). Technical sources confirm the front suspension is MacPherson strut, which uses a top “support sub‑assembly” (strut mount) with an integrated bearing, while the rear is a multi‑link setup with separate springs and dampers, so no rear strut mounts. References: Toyota Avensis (T27) Repair Manual – Front Suspension/“Front Shock Absorber with Coil Spring”, Toyota Europe Electronic Parts Catalogue (Avensis ZRT/ADT 2015–2018) – Suspension & Axle group, Haynes Toyota Avensis (2009–2018) – Suspension chapter.

On the front of a 2018 Avensis, the strut mounts sit at the very top of the MacPherson struts, bolting the strut to the body and letting the strut rotate smoothly as the steering turns. They combine a rubber insulator (to soak up vibration and road harshness) with a thrust bearing (so the strut turns freely). When they’re healthy, steering feels light and precise, and the cabin stays quiet over bumps. As the rubber ages and the bearing dries out, owners may notice clunks over speed humps, a notchy feel when turning the wheel at parking speeds, wandering at motorway pace, or feathered tyre wear.

Servicing the Avensis is a good time to give the front strut tops a quick once‑over. Under the bonnet, look for perished rubber, cracked insulators, or visible play when the strut is rocked. During a road test, listen for creaks or knocks over low‑speed bumps and check steering return‑to‑centre behaviour. If symptoms are present, replacing strut mounts in axle pairs is the tidy approach, as wear is usually similar side to side. The job involves removing the strut, safely compressing the spring, swapping the mount and bearing, and refitting with new hardware where specified. It’s smart to renew the dust boot and bump stop at the same time, then get a wheel alignment to protect tyres and steering feel.

There’s no fixed kilometre interval, but many techs inspect at every service and consider replacement around the 100,000–150,000 km mark if noise or steering roughness shows up. Using quality mounts with a proper sealed bearing pays off in smoother steering and longer life, especially on rough Kiwi and Aussie roads.

• Front axle: uses strut mounts with bearing (MacPherson strut)
• Rear axle: no strut mounts (multi‑link with separate damper and spring)
• Always follow torque specs and alignment procedures after replacement

Popular questions about 2018 Toyota Avensis strut mounts

How do I know my Avensis front strut mounts are worn?

Common clues are a dull clunk over low‑speed bumps, a graunchy or notchy feel as you turn the steering at a standstill, and light tramlining at motorway speeds. You might also spot uneven or feathered tyre wear. Under the bonnet, cracked rubber around the strut top or visible movement when someone rocks the car can also give the game away.

Do I need an alignment after replacing strut mounts?

Yes. The strut is a locating member in the MacPherson setup, so removal and refit can nudge camber and toe. A proper four‑wheel alignment after the job helps the Avensis track straight and protects your tyres. It’s a small extra step that saves money down the road.

Should strut mounts be replaced with the struts?

They don’t strictly have to be, but it’s sensible. If the struts are due, the spring is already compressed and the assembly’s out, so fitting fresh mounts and the bearing at the same time avoids double labour. Many techs replace in pairs to keep steering feel and ride balanced across the front axle.
