Parts for your 2011 Toyota Bb-Universal joints

Are universal joints used on the 2011 Toyota bB?

Short answer: not on the driveline. Technical references including Toyota’s Electronic Parts Catalog (EPC) for the bB QNC20/QNC21 series (2011 model year) and Toyota Repair Manual sections for Drivetrain/Axle – Front Drive Shaft show the bB as a front‑wheel‑drive (FF) vehicle using inboard and outboard constant velocity (CV) joints on the left and right drive shafts. There’s no propeller shaft or rear differential listed, so there are no driveline universal (Hooke) joints fitted. Toyota’s New Car Features (NCF) material for the QNC‑series bB also describes the FF layout. The only cross‑type joint shown in the EPC is on the steering intermediate shaft, which is part of the steering system, not the powertrain.

That’s why chasing a “universal joint” for a 2011 Toyota bB’s drivetrain will lead nowhere. What owners actually need, when diagnosing click‑clack noises on full lock or shudder under load, is to inspect the CV joints and their rubber boots on the front drive shafts.

Why the bB doesn’t use driveline universal joints comes down to how a small FF car is engineered:

• Steering angle and smoothness: CV joints deliver constant angular velocity through big steering angles, so the bB steers smoothly without the speed fluctuation a single U‑joint would introduce.
• Packaging and efficiency: With the engine and transaxle up front, there’s no need for a long prop shaft (where U‑joints live) running to the rear.
• NVH and durability: CV joints better manage torque pulses and angles common in city running, cutting vibration and wear.

Worth noting for completeness: the steering column’s intermediate shaft does use a small universal joint. If there’s a notchy feel, a knock over bumps, or the wheel won’t self‑centre nicely, that joint could be worn or seized. It isn’t a grease‑and‑go item, the usual repair is replacing the intermediate shaft assembly, as outlined in Toyota repair procedures (Steering – Column/Intermediate Shaft) and the EPC (Steering section, 45220‑xxxxx part family).

For regular servicing on a bB, mechanics should check the CV boots for splits, fling, or grease loss, replace damaged boots early to save the CVs. If clicking on turns persists, a replacement shaft is typically the go. For the steering U‑joint, check for rust, play, or stiffness and replace the shaft if needed.

FAQs

Does the 2011 Toyota bB have universal joints in the driveline?

No. The 2011 bB (QNC20/QNC21) runs front drive shafts with CV joints and no prop shaft, so there are no driveline U‑joints. Toyota’s EPC and Repair Manual sections for Front Drive Shaft confirm CV joints only.

What should be replaced if someone says the “universal joint” is worn on a bB?

If the symptom is clicking on turns or grease everywhere near a front wheel, that’s a CV joint or boot issue—replace the boot or the complete drive shaft. If the issue is a steering knock or stiffness, it’s likely the steering intermediate shaft U‑joint, replace the shaft assembly.

How should a bB’s joints be maintained during servicing?

Inspect CV boots each service for splits and grease fling, renew boots promptly or fit an exchange shaft if the joint is noisy. For the steering U‑joint, check for play, rust, or tight spots, it’s not a lube item, so swap the intermediate shaft if worn and torque the fasteners to spec.
