Parts for your 2012 Toyota Wish-Strut mounts

2012 Toyota Wish strut mounts: what they do and when to replace them

Technical references including Toyota’s Repair Manual and New Car Features for the ZGE2# series, along with Toyota’s Electronic Parts Catalog, confirm the 2012 Toyota Wish runs a MacPherson strut front suspension. That layout uses an upper strut mount (often called a support sub‑assembly) with an integrated bearing. So, strut mounts are absolutely fitted on the front of this model.

On a 2012 Toyota Wish, the strut mounts sit at the top of the front struts, bolting the suspension to the body while isolating noise and vibration. Their built‑in bearing lets the strut turn smoothly with the steering. In day‑to‑day driving they carry vehicle weight, keep the front end quiet, and help maintain alignment as the wheels move and steer. When they’re healthy, steering feels light and consistent, and the cabin stays calm over rough roads.

As they age, the rubber insulator can harden or crack, and the bearing can dry out or seize. That’s when drivers start noticing creaks over speed bumps, a knock or clunk on take‑off or braking, notchy steering, “memory steer” (wheel not self‑centring cleanly), and sometimes uneven front tyre wear. Leaving worn mounts in place can accelerate wear of the struts and springs, and can make the Wish feel vague or skittish on corrugations.

There’s no strict replacement interval, but a practical guideline is to inspect the strut mounts at each major service and any time the front struts are out. By 80,000–120,000 km or 8–10 years, many originals are tired—especially if the vehicle sees rough roads, heavy loads, or lots of urban kerb hopping. When replacing front struts on a 2012 Wish, it’s smart to fit new mounts and bearings at the same time. Doing them in pairs keeps steering feel and ride balanced left to right.

• Watch for: clunks over bumps, creaks when turning the wheel, steering that feels sticky, front‑end wander, or scalloped front tyres.
• Service tips: replace in axle pairs, use new self‑locking nuts, avoid hammering the strut shaft with an impact gun, align the mount orientation marks correctly, and book a wheel alignment straight after.
• Good add‑ons while you’re in there: new dust boots, bump stops and upper spring seats.

A technician will also check the strut towers for rust or elongated holes, torque the mount hardware to spec, and road‑test to confirm quiet operation and clean self‑centring. Done right, fresh mounts restore that tidy Toyota steering feel and cut down on cabin harshness—nice for long Kiwi or Aussie road trips.

Does a 2012 Toyota Wish have strut mounts?

Yes. The 2012 Wish uses MacPherson struts at the front, which require upper strut mounts with bearings. The rear suspension doesn’t use strut mounts in the same way, so the “strut mount” discussion is focused on the front end.

How long do strut mounts last on a 2012 Wish?

There’s no fixed lifespan, but many will show wear between 80,000 and 120,000 km. Harsh roads, heat, heavy loads and age all speed things up. If the front struts are due, consider mounts and bearings at the same time.

Can worn strut mounts cause a steering knock or uneven tyre wear?

They can. A collapsed insulator or rough bearing often shows up as clunks over bumps, creaks on steering, and can contribute to feathered or scalloped front tyres. Replacing mounts and aligning the wheels usually restores proper steering feel and tyre wear.
