2010 Toyota bB Front Struts — What They Do and How to Look After Them

Based on Toyota service literature and the Toyota Electronic Parts Catalogue for the QNC20/21 series (the 2010 bB), this model runs a MacPherson strut front suspension with a stabiliser bar, and a torsion-beam rear with separate shock absorbers. In other words, struts are absolutely relevant to the front of the 2010 Toyota bB, while the rear uses conventional shocks, not struts. This layout is also reflected in independent technical references and parts listings for the second‑generation bB.

Up front, the struts do more than just soak up bumps. A MacPherson strut is a structural part of the suspension: it houses the damper, supports the coil spring, locates the steering knuckle, and helps keep wheel alignment steady. Good struts keep the tyres planted, rein in body roll and dive, and make the bB steer predictably — handy around town and on those longer Kiwi and Aussie road trips.

As part of regular servicing, they’re worth a look every 20,000 km. Tell‑tales that the front struts are getting tired include: a floaty or bouncy feel, clunks over bumps, oil seepage on the strut body, longer braking distances due to nose‑dive, and uneven tyre wear (cupping or feathering). If any of that shows up, it’s time to plan a replacement before it knocks the tyres and brakes around.

• Replace in pairs left/right to keep handling balanced.
• Use new top mounts/bearings, dust boots and bump stops — they’re cheap insurance.
• Get a proper wheel alignment straight after the job, camber and toe can shift when struts are changed.
• Torque suspension fasteners at normal ride height to avoid bush bind and early wear.

There’s no hard‑and‑fast interval, but many bB front struts are due somewhere around 100,000–150,000 km, earlier if they’ve copped rough roads, corrugations or big city potholes. Quality replacement struts will sharpen steering response, cut down brake dive, and smooth out the ride. If reusing springs, check for sag or cracks, if the car sits unevenly, new coils may be wise. And because the rear is shocks, not struts, don’t forget to check those too — pairing fresh fronts with shot rears won’t deliver the result you’re chasing.

Popular questions about 2010 Toyota bB struts

Does the 2010 Toyota bB have rear struts?
No — the rear uses a torsion‑beam axle with separate shock absorbers and coil springs. Only the front uses MacPherson struts. If you’re pricing parts, make sure you’re ordering front struts and rear shocks, not four struts.

How often should the front struts be replaced?
There’s no fixed schedule. Inspect every service, many bB owners see best results replacing fronts somewhere around 100,000–150,000 km. If you notice oil leaks, clunks, poor control over bumps, or uneven tyre wear, bring replacement forward.

Do you need a wheel alignment after fitting front struts?
Yes. Strut replacement can nudge camber and toe out of spec. A post‑fitment alignment helps protect tyres and keeps the bB tracking straight and tidy.
