Parts for your 2006 Toyota Bb-Driveshafts

2006 Toyota bB driveshafts: what they do and how to look after them

Technical documentation confirms driveshafts are fitted to the 2006 Toyota bB. Toyota’s Repair Manual for QNC20/21/25 (Drivetrain/Axle section, 2005–2007 coverage) details “Front Drive Shaft Assembly (LH/RH)” with constant velocity joints and boots. The Toyota Electronic Parts Catalogue for 2006 bB likewise lists front driveshaft assemblies, and on 4WD QNC25 variants a propeller shaft to the rear differential. So driveshafts are absolutely relevant on this model.

The bB’s driveshafts are the sturdy CV axle shafts that send power from the transaxle to the front wheels, flexing as the suspension moves and as the wheels steer. Each shaft uses inner and outer CV joints to keep the drive smooth on full lock and over bumps, so the car pulls cleanly without vibration. On 4WD versions there’s also a propeller shaft running to the rear diff, but for most Aussie and Kiwi bB owners it’s the front CV shafts doing the daily graft.

Good servicing is mostly about keeping the CV boots happy. At each service interval, a quick look behind the front wheels for split boots, loose clamps, or flung grease pays off. Any grease mist on the lower control arm or inside the rim usually means a boot has let go. Catching a torn boot early and re-booting the joint with fresh moly CV grease can save replacing the whole shaft.

Typical warning signs include clicking on full lock when parking, a shimmy under throttle, or a rhythmic vibration with speed. If there’s clicking or the joint feels gritty once cleaned, it’s time for a new driveshaft assembly. Use new axle nuts, seat the shaft fully in the transaxle to protect the oil seal, and torque everything to the factory spec from the Toyota manual. After major front-end work, it’s smart to check wheel alignment.

Quality parts matter. Genuine or reputable aftermarket shafts with thermoplastic boots and high-moly grease last longer, especially if the car’s lowered or sees lots of stop–start work. Driving habits help too: avoid hard launches on full lock, and keep an eye out after pothole hits. With regular boot checks every 10,000–15,000 km, most bB CV shafts will clock up big kilometres without drama.

• Inspect CV boots and clamps at every service.
• Address leaks or tears immediately to prevent joint damage.
• Replace noisy or loose joints/shafts and use new hardware.

Popular questions about 2006 Toyota bB driveshafts

Does a 2006 Toyota bB have driveshafts?
The 2006 bB is front-wheel drive by default and uses two front CV driveshafts. Some 4WD variants also have a propeller shaft to the rear differential. Either way, driveshafts are part of the driveline.

How long do the bB’s CV driveshafts usually last?
With intact boots and quality grease, many make it well past 150,000 km. Harsh roads, torn boots, or lowered suspension can shorten that. Regular inspections are the key to long life.

What are the signs a driveshaft needs replacing?
Clicking on full lock, vibration under acceleration, grease sprayed around the inner wheel area, or a torn boot are the big giveaways. If a joint clicks or feels rough, replace the shaft assembly.
