2000 Toyota bB Wheel Hubs: What They Do and How to Look After Them

Technical sources confirm wheel hubs are absolutely relevant on the 2000 Toyota bB. Toyota Service Information (TIS) for the NCP20/NCP21 platform and the Toyota Electronic Parts Catalogue (EPC) list both front and rear hub and bearing components for this model, with variations for ABS-equipped cars. Aftermarket catalogues aligned to Toyota’s data also show replacement hub/bearing options for the front knuckle and the rear drum-brake assembly on early bB models. So yes—this vehicle is fitted with wheel hubs and relies on them for safe, smooth running.

On a 2000 bB, the wheel hub is the bit that the wheel bolts to, it supports the wheel studs, houses the bearing, and provides the mounting face for the brake rotor or drum. At the front, the driveshaft splines through the hub to deliver torque, and on ABS variants there’s a tone ring or encoder to feed wheel speed data to the ABS module. The hub keeps everything centred so the tyre tracks straight and the brakes behave predictably.

Because the bearings are sealed, routine servicing is more about inspection than adjustment. During tyre rotations or brake work, a quick check for roughness or play is smart. Spin the wheel and listen for a low humming or growl that rises with road speed, gently rock the wheel at 12 and 6 o’clock to feel for looseness. Any ABS warning light, unusual heat at the hub after a drive, or uneven brake performance can also point to a hub or bearing on the way out.

Replacement on the bB typically involves pressing out a worn bearing from the front knuckle and refitting the hub and new bearing, or swapping the rear hub/bearing assembly on drum-brake models. It pays to use quality parts that match the car’s build—ABS versus non-ABS—and to follow factory torque specs for axle nuts, hub bolts and wheel nuts. A fresh axle nut, cotter pin (where used), and a clean hub face help avoid future drama. After fitment, road test for noise, recheck for any play, and keep an ear on things over the next few hundred kilometres.

To stretch hub life, avoid hard kerb hits, keep tyres balanced and aligned, and fix any torn CV or hub seals promptly so water and grit don’t move in. Many bB hubs run happily well past 150,000–200,000 kilometres if the rest of the suspension and tyres are looked after.

• Common symptoms: droning noise with speed, wheel play, ABS light, uneven braking.
• Good practice: inspect at each brake service or 20,000 km, fit quality parts, follow torque specs.

Popular question: How can someone tell if a 2000 Toyota bB wheel hub or bearing is failing?

A steady humming or droning that changes with road speed is the classic sign. If the sound shifts when loading one side of the car (gentle lane change), that’s another clue. Play when rocking the wheel at 12 and 6 o’clock, heat at the hub after a drive, or an ABS light on cars with ABS are also common flags.

If in doubt, a mechanic can check for roughness with the wheel off and the hub spun by hand, and measure play against factory limits.

Popular question: Are the bB’s wheel bearings serviceable or sealed?

They’re sealed bearings. On the front, the bearing is pressed into the steering knuckle and works with the hub, practical service is replacement of the bearing (and often the hub if worn). The rear (with drum brakes) commonly uses a hub and bearing assembly that’s replaced as a unit. There’s no routine greasing or adjustment.

Popular question: How often should wheel hubs be checked on a 2000 bB?

They’re worth a look at every brake service or roughly every 20,000 km. Also check any time tyres are rotated or if there’s noise, vibration, or an ABS warning. While there’s no fixed replacement interval, high-kilometre cars or those driven on rough roads should be monitored more closely.
