Parts for your 2010 Toyota Bb-Steering bushes

2010 Toyota bB steering bushes — what they do and when to replace them

Based on Toyota technical documentation for the QNC21-series bB (2010 model year) — including the Toyota Electronic Parts Catalogue and the Toyota/Daihatsu workshop manuals for the column-assist EPS rack-and-pinion system — the vehicle uses steering bushes. Specifically, it has rubber “cushion” bushes that secure the steering rack to the subframe/crossmember, and support bushes within the steering column assembly. So, steering bushes are relevant on a 2010 Toyota bB.

On this bB, the steering bushes isolate vibration and noise from the rack-and-pinion while keeping the rack precisely located. That balance matters: too soft and the steering feels vague, too hard and you cop extra road harshness through the wheel. With age, heat, and Aussie/Kiwi road conditions, the rubber can harden, crack, or compress, which shows up as looseness on-centre, a dull clunk over sharp bumps, or the car tracking with the road camber.

During routine servicing, it’s smart to visually check the rack-mount bushes for cracks, oil swell, or deformation, and gently lever the rack to see if it shifts in its brackets. Also listen for a knock when rocking the steering wheel with the engine off. If there’s free play that isn’t in the tie-rods or column joints, the bushes could be the culprit. Many owners notice an improvement in steering feel after fresh bushes and a proper wheel alignment.

• Common signs they’re tired:
  • Knock/clunk through the column on bumps or when parking
  • Wandering or tramlining on the motorway
  • Inconsistent on-centre feel or delayed response
  • Visible cracking or perishing of the bush rubber
• Service tips:
  • Inspect at least every 20,000 km or 12 months, sooner if you drive on corrugated or coastal roads
  • Replace in axle pairs (both rack mounts) to keep geometry even
  • Torque the rack brackets to spec and get a wheel alignment afterwards
  • Choose OEM-style rubber for comfort, or quality polyurethane for sharper response (with a touch more NVH)

If there’s still noise after new bushes, check the intermediate shaft joints and the column support bush, EPS column rattle can mimic a rack bush issue. A reputable workshop familiar with Toyota/Daihatsu EPS setups will diagnose quickly and keep the bB’s steering tight and confidence-inspiring.

Popular questions about 2010 Toyota bB steering bushes

How do I tell if the steering bushes are worn on my 2010 bB?
Look for a dull knock over potholes or when you rock the wheel at a standstill, vague on-centre feel, and the rack shifting when gently pried during an inspection. If tie-rods and ball joints are sound but there’s still movement or cracking in the rack cushions, the bushes are likely done.

A test drive on a smooth road can help: light steering corrections that feel delayed or rubbery often point to tired bushes rather than alignment alone.

Should I fit polyurethane bushes or stick with OEM rubber?
For daily driving, OEM-style rubber keeps the bB quiet and comfy while restoring factory feel. Polyurethane sharpens response and lasts longer, handy for spirited driving or rough roads, but it can add a bit more vibration through the wheel.

If you value refinement over razor-sharp feel, rubber’s the safe bet. If you want crisper feedback, quality poly is worth it.

Do I need a wheel alignment after replacing steering bushes?
Yes. Even though you’re not changing tie-rods, the rack’s position can shift slightly when new bushes go in. An alignment ensures toe is bang-on, the steering wheel sits straight, and tyre wear stays even.
