2000 Toyota bB Steering Rack — Purpose, Servicing and Replacement

Based on Toyota service literature for the NCP30/NCP31 bB platform and the Toyota Electronic Parts Catalogue (EPC), the 2000 Toyota bB uses a rack-and-pinion steering gear. The closely related 2004–2006 Scion xB repair manual (same platform) also describes a rack-and-pinion setup with electric power steering assist at the column on most models. So yes, a steering rack is fitted and is directly relevant to the 2000 Toyota bB.

The steering rack on a 2000 Toyota bB converts the driver’s steering wheel input into precise side-to-side movement that turns the front wheels. It’s compact, direct, and gives the light, predictable feel drivers expect from a nimble city car. Most early bB models pair a manual rack with electric power assist on the steering column, some markets may have hydraulic assist. Either way, the rack itself is the heart of the system, linking the pinion to inner and outer tie rods for crisp control.

As part of regular servicing, it pays to give the steering rack a once-over every 20,000–30,000 kilometres or annually. A technician will check rack boots for splits, look for play in inner and outer tie rods, and feel for free play at the wheel’s centre. They’ll also listen for knocks over bumps and assess steering return-to-centre. Uneven front tyre wear, a wandering feel on the motorway, or a notchy sensation can all hint at wear in the rack or tie rods.

If replacement is on the cards, the job typically involves disconnecting the tie rods, unbolting the rack from the crossmember, and carefully removing it. On EPS/column-assist cars, there are no hydraulic lines to worry about, on hydraulic variants, lines must be capped, refitted with new seals, and the system bled with the correct fluid. Always fit new rack boots and tie-rod lock-nuts, and replace any cotter pins. After installation, the steering must be centred and a four-wheel alignment carried out. If the vehicle is equipped with EPS zero-point calibration, a scan tool procedure may be required so the assist behaves properly on-centre.

Quality reconditioned racks are a smart pick if the original has excessive play, damaged teeth, or severe wear. Mild issues like a torn boot or a single worn tie rod can sometimes be handled without replacing the entire rack, but any visible internal corrosion or persistent clunking under load is a sign to swap the unit. Done right, a fresh rack restores tight, confident steering feel and protects those front tyres from premature wear.

• Inspect: rack boots, inner/outer tie rods, mounting bushes
• Symptoms to watch: free play, knocks, off-centre feel, uneven tyre wear
• After any steering work: centre the wheel and get a professional wheel alignment

Popular questions about 2000 Toyota bB steering racks

Does a 2000 Toyota bB use power steering fluid?
Many 2000 bB models use electric power assist on the column, so there’s no power steering fluid or pump to service. Some market variants use hydraulic assist, those will have a reservoir, hoses and fluid that should be checked for level and leaks. A quick look under the bonnet for a PS reservoir or the presence of hydraulic lines at the rack will tell which system is fitted.

What are the common signs the steering rack or tie rods are worn on a bB?
Play or a knock felt through the wheel over small bumps, a wandering feel at motorway speeds, or a steering wheel that doesn’t return to centre smoothly are classic signs. Uneven or accelerated front tyre wear can point to inner or outer tie-rod wear. Torn rack boots often let moisture in, accelerating internal wear—spotting and replacing a split boot early can save a rack.

Do you need a wheel alignment after replacing the steering rack?
Absolutely. Any time the rack or tie rods are removed, the front toe setting changes. A professional alignment brings the geometry back to spec, protects tyre life, and ensures the car tracks straight. If the vehicle has EPS with a centring or zero-point procedure, that should be completed with a scan tool after the mechanical alignment.
