Parts for your 2013 Toyota Bb-Cv boots

2013 Toyota bB CV boots — what they do and how to look after them

Based on Toyota’s technical literature, CV boots are absolutely fitted to the 2013 Toyota bB (QNC20/21/25 series). The Toyota bB Repair Manual sections covering Front Drive Shaft, and the Toyota Electronic Parts Catalogue both list inner and outer “boot kit, front drive shaft” for this model year, confirming the vehicle uses constant velocity joints protected by rubber/thermoplastic boots.

On a 2013 Toyota bB, the CV boots are the flexible gaiters that seal grease around the constant velocity joints on the front drive shafts. Their job is simple but critical: keep the special moly grease in, and water, grit, and road crud out. That way the CV joints stay smooth as they handle steering angle and suspension movement without nasty clicking or vibration.

As part of routine servicing, the bB’s CV boots deserve a quick eyeball every service interval. A workshop will check for splits, perished rubber, loose clamps, or tell-tale grease flung around the inner wheel, strut, or undertray. If a boot’s torn, it should be replaced pronto before the joint runs dry and chews itself out. Once a joint starts clicking on full lock, you’re often looking at a complete shaft replacement, not just a boot.

Replacement is straightforward for an experienced tech: remove the shaft, clean the joint thoroughly, pack it with the correct molybdenum-disulphide CV grease, slide on a quality OE-style boot, and crimp new clamps. Using the right grease and fresh clamps matters, as does torquing the hub nut to spec from the Toyota bB repair manual. Universal “stretch” boots can get you out of trouble, but OE-style thermoplastic boots generally last longer.

Handy tips that keep a bB happy on Aussie and Kiwi roads:

• Inspect CV boots at each service or every 10,000–15,000 kilometres, especially if you drive on gravel or through floods.
• Look for: grease spray on the wheel/guard, cracks in the bellows, clicking on tight turns, or shudder under load.
• Replace boots early, it’s cheaper than replacing a whole shaft after grit gets in.
• If a boot failed and you kept driving, have the joint assessed—contamination can be sneaky.

These checks keep the bB’s driveline quiet, tidy, and roadworthy, and help avoid WOF/regos hassles from grease leaks near brakes or suspension.

Popular questions about 2013 Toyota bB CV boots

How often should CV boots be checked on a 2013 bB?
They’re best inspected at every service. For most owners that’s about every 10,000–15,000 kilometres or 6–12 months. If you’re driving on gravel roads or through standing water, ask your mechanic to pay extra attention, as boots cop more grit and can age faster.

Is it safe to drive with a torn CV boot?
Short trips might be okay, but it’s risky. A torn boot lets the grease out and water in, which can quickly damage the joint. If you spot grease around the wheel or see a split, book a boot replacement soon to avoid needing a full driveshaft.

What does a CV boot replacement typically involve?
The shaft is removed, the joint is cleaned and repacked with the correct moly grease, then a new OE-style boot and clamps are fitted. It’s a routine job for a workshop and often done within a few hours depending on side and condition.
