Parts for your 2014 Toyota Bb-Rack boots

2014 Toyota bB rack boots — what they do and how to look after them

Technical sources confirm the 2014 Toyota bB uses rack boots. The Toyota bB (QNC2# series) steering system is a rack-and-pinion layout with column-assist electric power steering, the Toyota Repair Manual steering section and Toyota Electronic Parts Catalogue list bellows-type dust boots fitted to each end of the steering rack. The Daihatsu-based platform mates (Materia/Subaru Dex) show the same arrangement, reinforcing that rack boots are standard equipment on this model year.

On a 2014 bB, rack boots (also called bellows) keep grit, water, and road grime out of the inner tie rods and rack bar. They also let air move as the rack travels, without letting in muck. If a boot splits, the inner joint can dry out or cop contamination, which quickly wears the rack and can turn into play at the wheel or a notchy feel. Left too long, it can cost a rack replacement rather than a simple boot swap.

As part of routine servicing, it’s smart to give the boots a proper look while the front is in the air. Anyone doing tyres, brakes, or a WOF/rego check can spot issues early: look for grease sling on the control arms, perished rubber, or clamps that have let go. A torch and a quick lock-to-lock turn usually tells the story.

Replacement is straightforward but benefits from care:

• Use quality boots designed for the bB’s rack diameter and stroke, universal boots can kink or chafe.
• Fit new inner and outer clamps, avoid cable ties as they can loosen with heat and time.
• Keep the boot’s breather pathway clear so it doesn’t balloon or collapse on full lock.
• If the tie rod end is removed, get a wheel alignment afterwards to protect tyre life.
• With EPS, there’s no hydraulic fluid inside the boots, so any oil inside usually means a separate leak, still, any grease contamination needs cleaning before the new boot goes on.

For most bB owners, a quick check every service or 10,000 km is plenty. In coastal areas or if the car sees gravel roads, look more often. Spot a crack early, swap the boot, and the rack will generally solider on for years with no dramas.

How often should rack boots be replaced on a 2014 Toyota bB?

There’s no fixed interval, they’re replaced on condition. If the rubber is supple and clamps are snug, keep rolling. When cracks, splits, or loose clamps show up, it’s time to change them. Many owners get well over 100,000 km before needing boots, depending on climate and road grit.

What are the signs a bB rack boot has failed?

Grease flicked around the inner guard or control arm, visible splits in the bellows, or dirt packed inside the folds are tell-tales. You might also feel slight steering play if the inner joint has copped grit, but that’s usually later in the piece.

Is it safe to drive with a torn rack boot?

Short trips to a workshop are usually fine, but it shouldn’t be put off. A torn boot lets in water and road grit, which can quickly wreck the inner tie rod and rack. Replacing the boot promptly is cheaper than chasing a worn rack and an alignment later.
