Parts for your 2009 Toyota Bb-Steering rack

2009 Toyota bB steering rack

Yes — a steering rack is fitted to the 2009 Toyota bB. Technical sources including the Toyota Electronic Parts Catalogue (Steering – Gear & Linkage listings for QNC20/QNC21) and the Toyota bB (QNC20/21) repair manual within Toyota’s Global Service Information (TIS) show a rack-and-pinion steering gear used with an electric power steering (EPS) column-assist setup. Aftermarket catalogues for bB QNC20/21 also list complete rack assemblies and inner/outer tie-rod components, further confirming its use.

The steering rack on this bB converts the rotary input from the steering wheel and column into side-to-side movement at the front wheels. While the assist is electric at the column (so there’s no hydraulic pump or fluid), the mechanical heart of the system is still a rack-and-pinion gear. That combo keeps the steering light around town and stable on the motorway, yet precise enough for everyday driving.

As part of regular servicing, it’s worth giving the rack and its linkages a once-over. There’s no power steering fluid to top up or flush on this model, so the focus is on condition and play. Under the bonnet and underneath, technicians should check the rack boots, inner and outer tie rods, and the rack mounts. Any split boot can let water and grit in, which accelerates wear. If there’s looseness, a clunk over bumps, vague steering, or uneven tyre wear, it’s time for a closer look.

• Typical signs of rack or linkage wear: free play at centre, knocks over corrugations, wandering, or poor self‑centering.
• Inspection tips: check boot integrity, inner tie-rod axial play, outer tie-rod end joints, and rack bushing condition.
• Because it’s EPS, don’t expect leaks — fluid under the car likely points elsewhere.

When replacement is needed, quality matters. A new or properly remanufactured rack, plus new inner and outer tie rods and fresh boots, restores feel and safety. After fitting, a wheel alignment is essential. On EPS models, a scan tool procedure to set the steering angle/torque zero point may also be required, particularly if stability control is fitted. In typical Aussie and Kiwi conditions — rough chip, potholes, the odd gravel road — it’s smart to have these checks done at least every 10,000–15,000 km alongside tyre rotations.

Expect labour to run a few hours depending on equipment and corrosion, and always re-torque fasteners to factory spec. Done right, a good rack will comfortably go the distance for many years.

Popular questions about 2009 Toyota bB steering racks

Does the 2009 Toyota bB have power steering fluid?
No. It uses electric power steering (EPS) with a conventional rack-and-pinion gear, so there’s no hydraulic pump, hoses, or fluid reservoir to maintain. Steering feel issues usually trace to rack wear, tie-rod joints, alignment, or EPS calibration — not fluid.

How long should a steering rack last on a bB?
With intact boots and good roads, many racks last well past 150,000–200,000 km. Frequent impacts, torn boots, or neglected tie-rod wear shorten lifespan. Regular inspections and prompt boot/joint replacement help the rack live longer.

What should be done after replacing the rack?
Fit new tie rods and boots, torque to spec, perform a wheel alignment, and carry out steering angle/torque zero-point calibration with a scan tool if required. A short road test to confirm straight-line tracking and self‑centering wraps it up.
