Parts for your 2006 Toyota Bb-Cv boots

2006 Toyota bB CV boots — what they do and when to replace them

CV boots are absolutely fitted to the 2006 Toyota bB. The Toyota Electronic Parts Catalogue (EPC) for QNC20/QNC21 models lists inner and outer front drive shaft boot kits, and Toyota’s official repair manual for the series details inspection and replacement procedures. Front‑wheel‑drive versions have CV boots on both front axles, 4WD variants add boots at the rear as well. So yes — they’re relevant on this model.

On the bB, CV boots are flexible rubber or TPE sleeves that seal each constant velocity joint, keeping high‑moly grease in and grit, water, and road crud out. They’re the only thing standing between a smooth, quiet driveline and a chewed‑out CV joint. Outer boots work the hardest because they flex on steering, while inner boots handle plunge movement as the suspension travels.

Good servicing always includes a quick look at the boots. A tidy shop will inspect them at every service or at least every 10,000–15,000 kilometres. If there’s grease flung around the inside of the wheel, on the strut, or under the engine tray, that’s a giveaway a boot has split or a clamp has loosened. Left unchecked, grease loss quickly leads to a noisy click on turns and, eventually, a failed joint.

Replacement is straightforward for a trained tech: remove the shaft (or joint), clean, repack with the correct CV grease, and fit new boots and clamps. If the joint is already clicking or has been exposed to grit, it’s smarter to replace the complete shaft assembly. Always use quality boots that match the bB’s joint diameter and shaft size, and new stainless clamps crimped with the right tool. After axle removal, the transaxle fluid level should be checked and topped up if needed. Many workshops prefer replacing boots in pairs on the same axle to keep wear even.

For Aussie and Kiwi owners, note that torn CV boots can cause a Roadworthy or WOF fail. It’s worth getting them checked after gravel‑road trips, deep puddles, or a brush with a wayward stick. Kept intact, CV boots can last well past 100,000 km, quietly doing their job while the bB goes about its day‑to‑day duties.

• Watch for: grease spray, clicking on full lock, or a burning‑grease smell near the wheel.
• Service tip: inspect at every service, replace immediately if split, per Toyota repair guidance.
• Parts tip: choose OEM or high‑quality aftermarket kits with correct grease and clamps.

Popular questions

Does a 2006 Toyota bB have CV boots?

Yes. Both the Toyota EPC and the factory repair manual for QNC20/QNC21 specify inner and outer front drive shaft boots. 4WD versions also have CV boots on the rear axles.

How often should CV boots be checked on a bB?

They should be inspected at every routine service or roughly every 10,000–15,000 km. Replace immediately if a boot is torn or a clamp has loosened, as grease loss quickly damages the joint.

Is it OK to drive with a split CV boot?

It’s risky. Once the boot splits, grease escapes and grit gets in, which can lead to clicking on turns and joint failure. It can also cause a WOF or Roadworthy fail, so prompt repair is the best call.
