2009 Toyota bB Struts — What They Do and When to Replace

Technical sources including Toyota’s Electronic Parts Catalogue for the QNC20/QNC21 series, the Toyota Repair Manual (Chassis) for these models, and major suspension catalogues from KYB and Monroe identify the 2009 Toyota bB as using a MacPherson strut front suspension with a torsion-beam rear (shock absorbers only). So yes, struts are fitted and relevant on the front axle of the 2009 bB.

Up front, the strut is the main suspension leg that combines a shock absorber and a spring seat, helping to locate the wheel hub while controlling bounce and body movement. On a compact, boxy runabout like the bB, healthy struts keep steering tidy, braking stable, and tyre wear even — exactly what’s needed for city hops and the odd open-road cruise across Aussie and Kiwi tarmac.

As part of regular servicing, it’s smart to have the front struts inspected every 20,000 km or 12 months. Look for oil weeping down the body, cracked or sagging rubber mounts, noisy top bearings when turning at low speed, and perished dust boots or bump stops. On the road, tell-tales include nose-diving under brakes, a jittery or floaty feel over bumps, steering shimmy, longer stopping distances, and feathered tyre edges. Many owners find front struts are due somewhere around 80,000–120,000 km depending on loads and road conditions.

When replacement time rolls around, do both fronts together to keep the car balanced. A wheel alignment is a must — strut removal can nudge camber and toe. It’s also a great opportunity to refresh the top mounts/bearings, dust boots and bump stops, and to check sway bar links and lower arm bushes while everything’s accessible. If reusing springs, a quality spring compressor and correct torque procedures are non-negotiable, otherwise, consider complete assembled struts to save time and reduce risk.

After fitment, expect a calmer ride, more confidence under brakes, and cleaner tyre wear. Given our mix of coarse-chip highways, potholes and speed humps, keeping the bB’s front struts in shape isn’t just comfort — it’s safety and savings at the tyre shop.

• Inspect every service, replace in pairs when worn.
• Always perform a wheel alignment post-replacement.
• Renew top mounts/bearings, boots and bump stops for best results.

Popular questions about 2009 Toyota bB struts

Does the 2009 Toyota bB have rear struts?
The 2009 bB uses front MacPherson struts and a rear torsion-beam with separate shock absorbers. So only the front end has struts, the rear uses conventional shocks. If the back feels bouncy or skittish, you’ll be looking at rear shocks rather than rear struts.

How long do the front struts typically last?
Many bB owners see 80,000–120,000 km before performance tapers off, but life varies with road quality and loads. If there’s oil seepage, odd tyre wear, knocking over bumps, or the car dives and floats, don’t wait for the odometer — get them checked and plan a replacement.

Do I need a wheel alignment after replacing front struts?
Absolutely. Any time front struts are removed, camber and toe can shift. A proper alignment will restore straight-line stability, steering feel, and protect your tyres from premature wear.
