Parts for your 2010 Toyota Bb-Steering bushes

2010 Toyota bB steeringbushes: what they do and when to replace

Based on Toyota’s technical publications for the QNC20/QNC21 series (2010 model year bB), including the Toyota Repair Manual (Steering section), the New Car Features (NCF) manual, and the Toyota Electronic Parts Catalogue (EPC), the vehicle uses a rack-and-pinion steering system with column-assist electric power steering. The steering rack is secured to the front subframe with rubber mounting bushes, and the column has guided support with bush/bearing components. That means steering bushes are absolutely relevant and used on a 2010 Toyota bB, often referred to here as steeringbushes.

On this compact Toyota, steeringbushes cushion the steering rack, keeping it accurately located while soaking up road harshness. They help the bB steer straight, protect the rack from shock loads, and trim down vibration that would otherwise travel up the column. When these bushes age, harden, or crack, the rack can shift slightly, which shows up as vague on-centre feel, a knock on sharp bumps, or a subtle clunk when turning at low speed—especially over kerbs or potholes common on Aussie and New Zealand roads.

For servicing of a 2010toyotabb steeringbushes setup, it’s smart to add a quick check at each regular service or WOF/rego inspection. Techs typically look for perished rubber, oil contamination from engine or rack seals, and any lateral rack movement while a helper turns the wheel. Replacement isn’t on a fixed kilometre interval, it’s condition-based. Many owners won’t need bushes before 100,000–200,000 km, but city kerb hits, gravel, or bigger wheels can bring that forward.

• Telltale signs: steering knock over bumps, wandering on the motorway, uneven tyre wear, and a “click” when rocking the wheel with the engine off.
• Good practice: inspect during every alignment, keep tyres correctly inflated, and avoid holding the steering hard against full lock.

When replacement is due, quality rubber bushes keep the factory ride and isolation. Polyurethane options can sharpen response but may raise NVH a touch—some drivers love the precision, others prefer OEM comfort. Proper installation matters: support the rack, replace bushes one side at a time, follow the workshop torque specs, and finish with a wheel alignment to reset toe. If the steering column support bush feels notchy or there’s play at the intermediate shaft, address those while you’re there.

Done right, fresh steeringbushes restore that tidy, confident feel the 2010 Toyota bB is known for—steady on centre, predictable in corners, and easy on tyres.

Popular questions about 2010toyotabb steeringbushes

Does the 2010 Toyota bB actually have steeringbushes?

Yes. The 2010 bB (QNC20/QNC21) runs a rack-and-pinion setup mounted to the subframe with rubber bushes, plus guided support in the steering column. These bushes are service items when wear is found, distinct from—but often checked alongside—control arm and sway bar bushes.

How often should steering bushes be replaced on a 2010 bB?

There’s no fixed interval. Inspect them at each service or alignment and replace when cracked, oil-soaked, or if the rack shows movement. Many last well past 100,000 km, but harsh roads, kerb strikes, and bigger wheels can shorten their life.

Rubber or polyurethane bushes for the bB rack—what’s better?

Rubber keeps the factory comfort and isolation, it’s ideal for daily drivers. Polyurethane firms up the rack location for sharper steering feel but can add a bit of vibration and road noise. Choose based on how the car’s used and the driver’s NVH tolerance.
