Parts for your 2000 Toyota Bb-Universal joints

2000 Toyota bB universal joints — are they used on this model?

Short answer: for most 2000 Toyota bB models (NCP30/NCP31, front‑wheel drive), universal joints aren’t part of the driveline. These cars use constant velocity (CV) joints on the front half‑shafts and don’t have a propeller shaft. This is supported by Toyota Electronic Parts Catalog (EPC) listings for the NCP30/31 series, which show front drive shafts with inner/outer CV joints and no rear propeller shaft. Engineering texts such as the Bosch Automotive Handbook and common SAE guidance also note that FWD layouts rely on CV joints for their ability to transmit power smoothly at high steering and suspension angles, something a simple cross‑type universal joint can’t do without speed fluctuation.

There is one important exception: the bB NCP35 (four‑wheel drive) variant, which was available in Japan around the same era, includes a rear propeller shaft that uses universal joints at each end. Toyota EPC entries for the NCP35 show a propeller shaft sub‑assembly with U‑joints, plus a rear differential. Toyota’s New Car Features material for the bB platform likewise distinguishes the 2WD and 4WD driveline layouts.

Why the typical 2000 bB doesn’t use driveline universal joints comes down to packaging and function. In a transverse‑engine, front‑drive setup there’s no long prop shaft to the rear, so there’s nowhere for U‑joints to live. CV joints are chosen because they maintain constant rotational speed through large angles, which keeps torque delivery smooth while steering and as the suspension moves. A basic U‑joint introduces angular velocity variation unless used in matched pairs on a straight‑through shaft, which is perfect for a rear prop shaft but not for steering knuckles and front hubs on a FWD hatch.

Practical tip: if you’re unsure which you’ve got, check the build plate code and underbody. NCP30/NCP31 (2WD) will show only front drive shafts with CV joints, NCP35 (4WD) will have a rear diff and a centre prop shaft with universal joints.

• 2WD bB (NCP30/NCP31): No driveline U‑joints, service the CV boots and joints instead.
• 4WD bB (NCP35): Driveline U‑joints present on the prop shaft, inspect for play, binding, or rust bleed at the bearing caps during servicing.

Note: separate to the driveline, the steering column typically uses a small universal joint in the intermediate shaft, but that’s a different component from the prop‑shaft U‑joint assemblies people usually mean by “universal joints”.

Popular questions about 2000 Toyota bB universal joints

Does my 2000 Toyota bB actually have universal joints?

Most don’t. If it’s a 2WD NCP30/NCP31, there are no driveline U‑joints — just CV joints up front. If it’s the 4WD NCP35, it will have a rear propeller shaft with universal joints. Look for “NCP35” on the build plate, a rear differential, and a prop shaft running down the centre of the car.

What should I service instead of universal joints on a 2WD bB?

Focus on the CV joints and boots. At each service, check for split or greasy boots, clicking on turns, or vibration under load. Replacing a torn boot early can save the joint, once grit gets in and it starts clicking, a complete driveshaft or CV joint replacement is usually the go.

How are U‑joints handled on a 4WD bB (NCP35)?

Many Toyota prop‑shaft U‑joints of this era are sealed and may be staked in place, so they’re inspected for play, roughness, rust bleed, or clunks on take‑off. If worn, the remedy can be a replacement joint or, on some assemblies, a complete prop shaft exchange. Regular underbody inspections — especially after water crossings or gravel road work — help catch issues early.
