Parts for your 2013 Toyota Bb-Driveshafts

2013 Toyota bB driveshafts — what they do and how to look after them

Based on Toyota service literature for the bB QNC2# series and listings in the Toyota Electronic Parts Catalog, the 2013 Toyota bB is front‑wheel drive and is fitted with left and right front driveshafts (CV shafts). These shafts link the transaxle to the front wheels via constant‑velocity joints. Being FWD, there’s no rear propeller shaft or rear differential on typical 2013 bB models, so “driveshafts” here refers to the front axle shafts with CV joints as shown in the factory Drivetrain/Axle—Front Drive Shaft sections.

On a 2013 bB, the driveshafts transfer engine torque smoothly to the front wheels while allowing suspension travel and steering angle. Each shaft uses inner and outer CV joints packed with grease and protected by rubber boots. When those boots split or clamps loosen, grease escapes, water gets in, and the joint wears, often first noticed as a clicking on full lock or a vibration under load.

As part of routine servicing, it’s smart to:

• Inspect CV boots every 10,000–15,000 km for splits, grease fling, or loose clamps.
• Listen for clicking on tight turns, shudder under acceleration, or a rhythmic knock—common signs of CV or shaft wear.
• Check for play at the wheel hub and inner joint, and look for leaking transaxle seals where the inner shaft enters the gearbox.

If a boot is torn but the joint hasn’t run dry, a boot kit and fresh CV grease can save the joint. If there’s clicking, corrosion, or blueing/pitting on the races, replacing the complete shaft assembly is usually the quickest, most reliable fix.

1. Use quality shafts and new hardware, replace hub nuts, circlips, and cotter pins as required.
2. Follow the workshop manual for shaft removal and fitment, hub‑nut torque and staking, and transaxle seal inspection. Top up or replace transaxle oil if any was lost.
3. After replacement, road test for noise and vibration, then recheck for leaks. A wheel alignment check is sensible if suspension was disturbed.

In Aussie and Kiwi conditions—coastal air, the odd gravel road—those rubber boots cop a fair hiding. Keeping them intact and the grease clean is the best way to get big kilometres from the bB’s driveshafts and avoid pricey joint failures later on.

Does the 2013 Toyota bB have driveshafts?

Yes. The 2013 bB is FWD and uses front driveshafts (CV shafts) on the left and right to drive the front wheels. It doesn’t normally have a rear prop shaft.

How long do the bB’s CV shafts usually last?

With intact boots, many will go well past 150,000–200,000 km. Premature wear usually follows split boots or contaminated grease, so regular inspections during services make a big difference.

What are the tell‑tale signs a bB needs a driveshaft or CV joint?

Clicking on full lock, vibration under acceleration, grease sprayed around the inner guard, or a clunk when taking off are the common red flags. Any of these should trigger a closer inspection.
