Parts for your 2010 Toyota Bb-Driveshafts

2010 Toyota bB driveshafts

Based on Toyota’s Electronic Parts Catalogue for the QNC20/QNC21/QNC25 series (2010 model year) and the Toyota bB repair manual procedures for “Front Drive Shaft (Axle) Removal/Installation”, the 2010 Toyota bB is fitted with driveshafts. Front-wheel-drive grades use left and right CV axle shafts, while 4WD grades also add a propeller shaft to the rear diff plus rear axle driveshafts. The Daihatsu Materia/Coo service literature (platform-mate to the bB) confirms the same arrangement.

On a 2010 bB, the driveshafts (often called CV axles) do the grunt work of carrying engine torque from the transaxle to the wheels, all while the suspension moves and the front wheels steer. Each shaft uses constant velocity (CV) joints and flexible boots packed with grease so everything runs smoothly without vibration. If the vehicle is a 4WD variant, there’s also a prop shaft sending drive to the rear, with rear CV shafts doing the final hand-off to the hubs.

For everyday servicing, it’s smart to give the CV boots and shafts a quick look every 10,000–15,000 kilometres or at each service. A split boot or flung grease is the early warning that a joint is running dry. Catch it then and a simple boot-and-grease job can save the cost of a full shaft. If left, the joint will wear, leading to clicking on full lock, shudder on take‑off, or a vibration under load.

• Check inner and outer CV boots for cracks, grease spray, or loose clamps.
• Listen for clicking on tight turns and feel for vibration during acceleration.
• Inspect transaxle seals where the shafts enter for weeping or leaks.
• On 4WD models, also check the prop shaft, centre bearing, and rear CV boots.

When replacement’s needed, many techs opt for complete rebuilt/new shafts rather than individual joints, as it’s quicker and often more cost‑effective. Use quality parts, new nuts/clips, and torque the axle nut to the factory spec, then re-stake or fit a new split pin as required. Avoid levering on the ABS tone ring, and support the lower arm properly to protect ball joints and wheel bearings. After the job, a quick road test for noise and a recheck for leaks is good practice. Wheel alignment usually isn’t affected by shaft work, but if other suspension parts were loosened, get it checked so the bB tracks straight and the tyres wear evenly.

Does the 2010 Toyota bB actually have driveshafts?

Yes. FWD models use left/right CV axle shafts. 4WD grades also have a propeller shaft and rear driveshafts. This is documented in Toyota’s EPC for QNC20/21/25 and the bB factory repair manual sections covering front drive shaft removal/installation.

What are the common signs the bB’s driveshafts or CV joints need attention?

Grease sprayed around the inner guard or chassis, split boots, clicking on full lock, vibration under acceleration, or a clunk when shifting between drive and coast are tell‑tales. Catching a torn boot early can often save the joint.

Should the CV boots be replaced or the whole shaft?

If the boot has just split and the joint is still quiet with no play, a new boot and fresh grease is fine. If there’s clicking, rust contamination, or noticeable lash, a complete shaft replacement is the better long‑term fix.
