Parts for your 2006 Toyota Ist-Strut mounts

2006 Toyota Ist strut mounts: purpose, checks, and when to replace

Based on Toyota’s factory documentation for the NCP60/NCP61 series (2002–2007) Ist — including the front suspension section of the Toyota Repair Manual and the Toyota Electronic Parts Catalogue (EPC, Suspension & Axle, Group 48) — the 2006 Toyota Ist runs a MacPherson strut front suspension with a dedicated upper support, commonly called the strut mount (also incorporates a bearing). The rear end uses a torsion beam with separate shocks and coils, so there’s no rear strut mount in the strict sense. In short: strut mounts are absolutely relevant and fitted at the front of a 2006 Toyota Ist.

On this model, the front strut mount does three important jobs. First, it supports the vehicle’s weight at the top of the MacPherson strut, locating the spring and damper securely in the body. Second, it isolates vibration and road noise so the cabin feels tidy on coarse-chip roads. Third, the inbuilt bearing lets the strut rotate smoothly with steering input, keeping the steering feel consistent and reducing kickback. When the mount or bearing wears, you’ll often hear a clunk over speed humps, a creak when turning the wheel at parking speeds, or notice feathered tyre wear.

As part of regular servicing on a 2006 Toyota Ist, a quick visual and tactile check under the bonnet is smart. Look for perished rubber, cracked or domed top hats, and listen for binding or graunching from the top mount when turning lock-to-lock. While there’s no fixed replacement interval, many drivers see wear from around 120,000–180,000 kilometres, especially on rougher Kiwi or Aussie roads. It’s best practice to replace strut mounts whenever you’re fitting new front struts or springs.

• Replace mounts in pairs (left and right) to keep steering feel even.
• Get a wheel alignment after any front suspension work.
• Inspect bump stops and dust boots at the same time, swap them if they’re cracked or missing.
• Choose quality OEM or reputable aftermarket mounts, cheap units can groan early or alter ride height.

If the steering feels notchy, the car tramlines, or there’s a dull thud over potholes, a fresh set of mounts and bearings can make the Ist feel tight and quiet again without breaking the bank.

How can someone tell if their 2006 Toyota Ist strut mounts are worn?

Listen for clunks over bumps, creaks when turning at low speed, and watch for uneven tyre wear. Under the bonnet, perished rubber, lifting top hats, or a notchy feel while steering are red flags.

Do the rear suspension parts on a 2006 Toyota Ist use strut mounts?

No. The rear is a torsion beam with separate shock absorbers and coils, so it uses shock mounts rather than MacPherson strut mounts. Front only for true strut mounts on this model.

Should strut mounts be replaced when fitting new front shocks on a 2006 Ist?

Yes, it’s wise. Replacing mounts and bearings with the shocks saves labour later, restores steering smoothness, and helps protect your new dampers from premature wear.
