Parts for your 2008 Toyota Bb-Strut mounts

2008 Toyota bB strut mounts — fitted up front and worth keeping in shape

Yes, the 2008 Toyota bB does use strut mounts — up front. Technical references including the Toyota Electronic Parts Catalogue (EPC) for the QNC20/QNC21 series and the Toyota Repair Manual for the model’s front suspension confirm a MacPherson strut layout with a dedicated top support/strut mount assembly. The rear suspension is a torsion beam with separate shocks, so there are no rear strut mounts.

On the 2008 Toyota bB, the front strut mounts sit at the top of each MacPherson strut, bolting the strut to the body under the strut tower. They do two big jobs: first, they isolate road noise and vibration so the cabin stays civilised, second, they provide a smooth pivot for the strut as the wheels steer. Inside the mount is a bearing or bearing plate that lets the spring and strut rotate without binding. When that bearing wears, owners notice notchy steering, a creak or clunk at low speeds, or a twang as the spring releases after turning.

As part of regular servicing on a bB, it’s smart to inspect the strut mounts any time the front suspension is apart — especially when replacing front struts, springs, or top bearings. Many shops in Australia and New Zealand replace the mounts with the struts as a pair, because labour overlaps and fresh mounts protect the new dampers. Expect life to vary with roads and loads, but by 100–150,000 km the originals can be tired.

• Common signs they’re due: dull thud over speed bumps, steering that won’t self-centre neatly, a knock when parking, or uneven tyre wear from geometry shift under load.
• Good practice: replace mounts in pairs, torque fasteners with the vehicle at ride height, and book a wheel alignment straight after.
• Noise hunting tip: with the bonnet up, have a helper turn the wheel lock-to-lock while listening at the strut towers — grinds or clicks often point to the top bearing.

Choosing quality mount assemblies pays off in quieter ride and sharper steering feel. If the bB does city kerb-hopping, carries a full crew, or runs on coarse-chip roads, checking the mounts each major service can save tyres and keep the front end feeling tight.

Popular questions about 2008 Toyota bB strut mounts

How long do front strut mounts typically last on a 2008 bB?

On local roads, many see 100–150,000 km before noise or steering roughness shows up. High heat, potholes, or heavy loads can shorten that. If fitting new front struts, doing the mounts at the same time is cost‑effective and helps the new dampers work properly.

Do worn strut mounts affect alignment on a bB?

They can. Excess play at the top of the strut can let camber and caster shift under braking or cornering, which shows up as feathered tyres or a pull. After any mount or strut work, a proper four‑wheel alignment is recommended.

Are front and rear strut mounts the same on the bB?

No. The 2008 bB only has strut mounts at the front. The rear uses a torsion beam with separate shock absorbers that have different upper mounts, not strut mounts.
