2001 Toyota bB steering bushes: what they do and when to replace them

Yes, the 2001 Toyota bB (NCP30/NCP31) uses steering bushes. Toyota’s Electronic Parts Catalog (EPC) for the bB lists rack-and-pinion mounting cushions/bushes within the Steering Gear & Linkage section, and the factory repair manual’s steering chapter illustrates the rack assembly secured to the subframe with rubber insulators. Equivalent documentation for the closely related Scion xB (NCP31) shows the same arrangement. So “steering bushes” are absolutely relevant to this model.

On this bB, the steering bushes are the rubber (or polyurethane, if upgraded) cushions that locate the steering rack on the front subframe. Their job is to isolate vibration, keep the rack square to the column and tie rods, and maintain precise geometry. When they age, harden, or split, the driver may notice a knock over sharp bumps, vague on-centre feel, or a slight wander that an alignment alone doesn’t cure.

As part of regular servicing in Australia or New Zealand conditions, it’s smart to have the bushes inspected every 20,000–30,000 km or at each WOF/reg/check. Any visible cracking, off-centre rack position, or free play under a pry-bar test means it’s time to replace. Because the rack’s location is critical, this is one of those small jobs that can make a big difference to steering feel.

• Replace bushes in pairs to keep the rack correctly aligned.
• Support the rack before unbolting the mounts, don’t let it hang on the intermediate shaft.
• Torque the bracket fasteners to the spec in the steering section of the bB manual, then re-check after a short drive.
• Book a wheel alignment afterwards, fresh bushes can subtly change toe.
• OE-style rubber keeps it quiet and comfy, quality polyurethane tightens response but may add a touch more NVH.

While in there, a technician should also check inner and outer tie rod ends, lower control arm bushes, and the intermediate shaft for play. If the car has had a front-end knock or subframe work, new steering bushes are cheap insurance to restore factory geometry. Following Toyota service literature and EPC references ensures the right parts, correct fit, and the steering feel this little box is known for.

Popular questions

Does a 2001 Toyota bB actually have steering rack bushes?
Yes. The Toyota EPC for the NCP30/NCP31 bB shows the rack-and-pinion secured with mounting cushions/bushes, and the factory repair manual diagrams the same setup. They’re a normal wear item.

What are the signs the steering bushes need replacing?
Common clues include a clunk over potholes, a slightly vague or wandering feel, and minor steering shimmy that persists after alignment. Visual cracks or movement of the rack under load are confirmation.

Rubber or polyurethane bushes for a bB?
Rubber is closest to factory comfort and isolation. Polyurethane tightens response and lasts well, but may transmit a bit more road feel. Either way, correct torque and a post-fit alignment are key.
