Parts for your 2009 Toyota Bb-Suspension bushes

2009 Toyota bB suspension-bushes: what they are and when to sort them

Suspension-bushes absolutely are fitted to the 2009 Toyota bB. Toyota’s repair manual for the bB (QNC20-series) and the Toyota Electronic Parts Catalogue (EPC, Group 48 Axle &, Suspension) list multiple bushes: front lower control arm bushes, stabiliser (sway) bar D-bushes and link bushes, rear torsion-beam pivot bushes, and strut top mounts. The shared platform used with the Daihatsu Materia/M4 supports the same arrangement. So, suspension-bushes are relevant to this model.

On this bB, bushes sit at key pivot points to isolate noise and vibration, hold alignment steady, and let the suspension move smoothly. Fresh bushes help the car track straight, brake predictably, and ride quietly. As they age, rubber hardens, cracks, or tears, which can lead to clunks over bumps, vague steering, and feathered tyre wear.

Common bush locations on a 2009 bB include:

• Front lower control arm bushes (front and rear positions)
• Front stabiliser bar D-bushes and stabiliser link bushes
• Rear torsion-beam to body pivot bushes
• Front strut top mounts (bushed mounts with bearings)

For servicing, technicians typically inspect bushes every 10,000–15,000 km or at scheduled services, looking for cracking, separation, oil swelling, or excessive movement with a pry bar. Any play, off-centre arm position, or perishing is a sign it’s time to replace.

Replacement can be done as individual press-in bushes or by fitting complete arms where available. Pressing bushes requires the right tools to avoid arm distortion, and final tightening should be done at normal ride height to prevent pre-load and premature wear. After control arm or rear beam bush work, a wheel alignment is recommended to keep tyre wear even and steering feel tidy.

Owners often choose between OEM-style rubber (quiet, comfy, factory feel) and quality polyurethane options (crisper response, longer life, mild increase in NVH). Either way, replacing bushes in axle pairs helps keep handling balanced. While in there, it’s smart to check ball joints, stabiliser links, and strut mounts. Many WOF/roadworthy inspections in Australia and New Zealand will flag torn or flogged-out bushes, so staying ahead avoids a fail and saves tyres.

Signs this bB needs suspension-bushes soon:

1. Clunks or knocks on speed humps or rough chipseal
2. Steering wander, tramlining, or steering wheel shimmy under brakes
3. Uneven or rapid tyre wear, especially inner shoulders

FAQs

How can someone tell if the 2009 bB’s suspension-bushes are worn?
A road test that reveals clunks over bumps, steering vagueness, or instability under braking is a clue. On the hoist, perished rubber, cracks, torn voids, or excessive arm movement with a pry bar confirm it. Uneven tyre wear also points to bush movement affecting alignment.

Rubber or polyurethane bushes for a daily-driven bB?
Rubber keeps the factory comfort and low noise the bB is known for. Polyurethane can sharpen steering and longevity, handy for spirited or heavily loaded use, but may transmit a touch more vibration. For most daily drivers, fresh rubber is ideal, for a sportier feel, quality poly options work well.

Is a wheel alignment needed after bush replacement?
Yes, if front control arm or rear beam bushes are replaced. Bush movement directly affects caster, camber, and toe. Aligning afterwards protects tyres, restores straight-line stability, and keeps steering effort consistent.
