Parts for your 2006 Toyota Bb-Cv joint

2006 Toyota bB CV joint: what it does, how it wears, and when to sort it

Yes — a CV joint is fitted to the 2006 Toyota bB. Technical references that confirm this include the Toyota Electronic Parts Catalogue (EPC) for model codes QNC20/QNC21/QNC25, which shows front drive shaft assemblies with an outboard constant velocity (Rzeppa) joint and an inboard plunge (tripod) joint. The Toyota Repair Manual for bB/ist covers front axle/drive shaft inspection and CV boot service procedures. Major aftermarket catalogues from drivetrain suppliers (e.g., NTN, GSP) also list complete shafts and CV joint/boot kits for 2005–2010 bB models, further verifying fitment. Most bB cars are front‑wheel drive, some markets also offered 4WD, which still relies on CV joints for the driven axles.

On a 2006 Toyota bB, the CV joint lets the front wheels steer and move with the suspension while still getting smooth, constant drive from the gearbox. The outer joint (at the wheel) handles big steering angles, while the inner joint allows in‑out “plunge” as the suspension travels. When the joints are healthy and well‑greased under intact rubber boots, they deliver quiet, vibration‑free power and long tyre and bearing life.

As part of routine servicing, it’s smart to eyeball the CV boots and clamps every service or roughly each 10,000–15,000 km. Look for:

• Grease flung around the inner wheel, lower arm, or subframe
• Cracks, splits, or loose clamps on the rubber boots
• Clicking or knocking on tight turns (usually the outer joint)
• Shudder or vibration on take‑off (often the inner joint or shaft wear)

If a boot is torn but the joint hasn’t started clicking, a new boot and fresh high‑moly CV grease can save the joint. Once clicking starts, a replacement joint or complete shaft is the go. Many workshops prefer swapping the full shaft on the bB — it’s quicker, includes new joints both ends, and reduces comebacks. Always use new clips/clamps, the correct type and quantity of CV grease, and torque the axle nut to the factory spec before staking or fitting a new cotter as required. After any shaft work, recheck wheel alignment and road test for noise on lock and vibration under load.

Choosing genuine Toyota or reputable aftermarket shafts/joints is worth it, they tend to seal better and last longer, especially with city driving and sharp parking manoeuvres common in NZ and Aus.

Popular questions about 2006 Toyota bB CV joints

Does a 2006 Toyota bB have CV joints?
Yes. The front drive shafts use an outer Rzeppa CV joint and an inner plunge (tripod) joint. 4WD variants, where fitted, also use CV joints for the rear/diff axles.

How often should CV boots be replaced?
There’s no fixed interval. Inspect at every service, replace immediately if a boot is cracked, split, or leaking grease. Catching a torn boot early can save the joint.

Can the CV joint be replaced on its own, or is a full shaft better?
Both are options on the bB. A joint/boot kit suits an isolated failure with a clean shaft. A complete shaft assembly is often quicker, comes with both joints new, and can be more economical on labour.
