Parts for your 2016 Toyota Bb-Universal joints

2016 Toyota bB universal joints — are they actually used?

Based on technical sources including the Toyota Electronic Parts Catalogue (EPC) for bB QNC20/QNC21/QNC25, the Toyota Repair Manual for QNC2# models, and workshop data shared with the Daihatsu Materia/Subaru Dex platform, a conventional driveline universal joint (on a propeller shaft) is not fitted to the common 2016 Toyota bB front‑wheel‑drive models (QNC20 1.3L and QNC21 1.5L). Those variants use a transaxle with front half‑shafts and constant‑velocity (CV) joints, so there’s no rear differential or prop shaft to require U‑joints. The only “universal” joints you’ll find on those cars are the small steering intermediate shaft joints, which are a different category to the driveline U‑joint most people mean.

Where universal joints do appear is on the less common 4WD bB (model code QNC25). The EPC for QNC25 lists a rear differential and a propeller shaft with U‑joints. If your 2016 bB is a typical Australian or New Zealand import, chances are it’s 2WD and a universal joint for the driveline isn’t relevant to your servicing parts list.

Why it’s not used on most 2016 bB models: the front‑wheel‑drive layout packages the engine, transaxle and drive shafts all up front. Torque goes through CV joints that accommodate both steering angle and suspension movement, doing the job a U‑joint would do on a longitudinal prop shaft. That’s lighter, simpler, and cheaper to maintain for city cars like the bB.

If you’re unsure which you’ve got, check for these 4WD clues:

• Model code on the build plate: QNC25 indicates 4WD.
• A visible prop shaft running to a rear differential.
• Owner’s manual or service data mentioning 4WD components.

Note: Steering column universal joints exist on all trims, but they’re typically serviced as part of the steering shaft assembly and aren’t the same as a driveline U‑joint.

Popular questions

Does a 2016 Toyota bB have universal joints?
Most 2016 bB models sold or imported into Australia and New Zealand are 2WD (QNC20/QNC21) and don’t use a driveline universal joint. The 4WD QNC25 does have U‑joints on its prop shaft. All versions have small steering shaft U‑joints, which are a separate item.

How can someone tell if their bB is 4WD and uses U‑joints?
Look for the model code QNC25 on the build plate, a prop shaft running to the rear, and a rear differential. If those are present, the vehicle uses U‑joints in the driveline. No prop shaft means no driveline U‑joint.

What maintenance applies if there are no U‑joints?
For 2WD bB models, focus on CV boots and joints at the front. Inspect boots for cracks or grease fling at each service and replace promptly if damaged. For the steering intermediate shaft U‑joints, check for free play or notchy movement if there’s a clunk in the column, and replace the shaft assembly if needed.
