2002 Toyota bB CV boots: what they do and how to look after them

CV boots are absolutely fitted to the 2002 Toyota bB. Technical sources that document this include the Toyota Electronic Parts Catalogue (EPC) for the NCP30/NCP31 bB, which lists both inboard and outboard front drive shaft boots, and the Toyota Repair Manual section covering Front Drive Shaft/Constant Velocity Joints, which details inspection and replacement procedures. Aftermarket parts catalogues for the equivalent Scion xB (same platform) also list inner and outer CV boot kits, confirming fitment.

On the 2002 bB, the CV boots are flexible rubber bellows that seal grease around each constant velocity joint on the front drive shafts. Their job is simple but critical: keep the special moly grease in and road grit, water, and dust out. When a boot cracks or splits, the grease gets flung across the wheel arch and the joint starts to run dry. That’s when clicking on tight turns, vibration on take-off, and ultimately a worn CV joint show up — none of which the owner wants on the daily commute.

As part of regular servicing on a 2002 Toyota bB, a quick visual under the front end pays off. A tech should check both inner and outer boots on each side for:

• Grease spray on the inside of the front rims, struts, or undertray
• Cracks, splits, or perished rubber, especially the folds
• Loose or broken clamps and any play in the joint

If a boot is only weeping or the rubber is starting to age, replacement now is far cheaper than a complete drive shaft later. Proper boot replacement means cleaning the joint, packing the correct spec CV grease, and fitting new clamps with the right tension. Universal “split” boots are a get-you-by option, but for durability the bB responds best to model-specific boots that clamp to the factory diameters. After refit, all fasteners should be torqued to the specifications in the Toyota manual and the axle nut staked correctly.

Inspection every service or 10,000–15,000 kilometres is a sensible interval for Aussie and Kiwi conditions. City kerbs, gravel drives, and summer heat can age boots faster than you’d expect. Keeping them intact helps the bB steer smoothly, pass a WOF or rego check, and avoid that tell-tale clicking around the carpark.

Popular questions about 2002 Toyota bB CV boots

Does a 2002 Toyota bB actually have CV boots?
Yes, it does. The front-wheel-drive bB (NCP30/NCP31) uses constant velocity joints on each front drive shaft, each protected by an inner and outer rubber boot. Toyota’s EPC and the factory Repair Manual list and service these parts, and aftermarket catalogues supply direct-fit boot kits for this model.

How often should CV boots be checked or replaced?
They should be checked at every routine service or roughly every 10,000–15,000 km. Replace a boot as soon as cracks, splits, or grease sling are found. A good boot can last well over 100,000 km, but once torn, the clock is ticking on joint wear.

Can universal or split boots be used on a bB?
They can be used in a pinch, but the best result comes from a model-specific boot that matches the bB’s joint and shaft diameters. Genuine or quality OEM-equivalent boots seal better, last longer, and are more likely to keep the WOF inspector happy.
