Parts for your 2011 Toyota Bb-Steering bushes

2011 Toyota bB steering bushes — are they used?

For the 2011 Toyota bB (QNC20/QNC21), “steering bushes” aren’t a service item because the vehicle doesn’t use separate, replaceable steering rack mounting bushes. The steering gear is a rack-and-pinion unit paired with column-assist electric power steering (EPS), and it’s bolted directly to the front crossmember without the typical rubber rack-mount cushions seen on some older or larger models.

This isn’t guesswork. Toyota’s Electronic Parts Catalogue for the QNC2# platform lists no “Bush, Steering Rack” or equivalent cushion parts, and the Toyota bB Repair Manual steering section outlines direct mounting of the gear to the member. The New Car Features material for this platform describes column-assist EPS that manages noise, vibration and harshness via the column and body structure rather than via rack bushes. You’ll also find that major aftermarket suspension catalogues in AU/NZ don’t offer steering rack bush kits for the 2011 bB, which backs up the OE documentation.

Why it’s designed this way: with column-assist EPS, Toyota targets a more direct steering feel and simpler packaging. NVH isolation is primarily handled by the column assembly, intermediate shaft joints, subframe mounts and control arm bushes. That means there aren’t separate rubber rack bushes to wear, squeak or deform — handy for long-term consistency, and one less part to chase during a service.

What to check instead if the steering feels loose or clunky:

• Outer and inner tie rod ends (play, torn boots, corrosion)
• Rack bellows (leaks, splits)
• Intermediate shaft universal joints and column coupler (binding or free play)
• Front lower control arm bushes and ball joints (they influence steering feel)
• Wheel alignment and tyre condition, pressures and wear patterns
• Steering gear mounting bolt torque and crossmember condition

Referenced technical sources for this conclusion:

• Toyota Electronic Parts Catalogue (QNC20/QNC21, Section 45 Steering Gear & Link) — no steering rack bush part listed
• Toyota bB Repair Manual (QNC2#) — Steering and EPS sections outlining rack-to-member direct mounting
• Toyota New Car Features for QNC2# platform — Column-assist EPS architecture and NVH strategy
• AU/NZ aftermarket catalogues (e.g., Nolathane, SuperPro) — no listing for 2011 bB steering rack mount bushes

FAQs

Does a 2011 Toyota bB have steering bushes to replace?
Not as a separate part. The rack is mounted directly to the crossmember, and Toyota doesn’t catalogue serviceable rack-mount bushes for the QNC2# bB. If there’s play, focus on tie rods, the intermediate shaft, and control arm bushes instead.

What should be serviced to sharpen the steering feel on a 2011 bB?
Start with outer and inner tie rod ends, inspect the rack bellows, check the steering column/intermediate shaft joints, and assess front control arm bushes and ball joints. Finish with a proper alignment and correct tyre pressures.

Can aftermarket polyurethane steering rack bushes be fitted to a 2011 bB?
There aren’t recognised kits for this model in AU/NZ catalogues because the bB’s rack doesn’t use separate bushes. Universal bushes aren’t recommended — they won’t suit the design and can compromise safety or alignment.
