Parts for your 2001 Toyota Bb-Rack boots

2001 Toyota bB rackboots: what they do and when to replace them

Based on Toyota’s own service literature for the NCP30/NCP31 series and the Toyota Electronic Parts Catalogue, the 2001 Toyota bB uses a rack‑and‑pinion steering assembly with protective bellows on each end. These are commonly called rackboots, steering rack boots, or gaiters. Workshop manuals and exploded diagrams for the bB show the bellows covering the inner tie rods and the rack ends, so rackboots are absolutely relevant and fitted to this model.

On a 2001 Toyota bB, rackboots keep road grit, water, and muck away from the steering rack and inner tie rod joints. They also help retain the correct lubrication around the joint area. When a rackboot splits, dirt and moisture can chew out the inner tie rod and rack seals in short order, leading to sloppy steering, premature wear, and potential power steering fluid leaks. It’s a small, inexpensive part that protects a very pricey assembly.

Good practice is to inspect the rackboots at each service (about every 10,000 km or 6 months), especially if the bB spends time on gravel or coastal roads. Look for cracks, splits near the concertina folds, loose clamps, or any wetness. A boot full of fluid usually points to a leaking rack seal rather than a boot issue, so that’s worth further investigation. Torn rackboots can trigger a WOF or roadworthy failure in NZ and Australia.

Replacement is straightforward for a trained tech and a tidy DIYer with the right gear. Plan to:

• Replace boots in pairs if one’s perished, the other won’t be far behind.
• Remove the outer tie‑rod end, counting turns or measuring to keep toe close, still get an alignment check after.
• Inspect inner tie‑rod play while you’re there, renew if there’s any knock or looseness.
• Use proper crimp or ear clamps rather than cable ties, ensure the boot isn’t twisted and can flex freely lock‑to‑lock.
• Avoid solvent sprays on new boots, a light wipe with a clean rag is enough.

If the steering feels vague, there’s a clicking over bumps, or you spot grease sling on the inside of the tyres, it’s time to book the bB in. Fresh rackboots are cheap insurance against a knackered rack.

How often should rackboots be replaced on a 2001 Toyota bB?

There’s no fixed kilometre interval, they’re replaced on condition. Have them inspected at each service. In harsh conditions or with lots of full‑lock parking manoeuvres, they can age faster. If cracking or splits show up, replace promptly to protect the rack and inner tie rods.

Can you drive with a torn rackboot on a 2001 bB?

You can, but it’s not a great idea. A torn boot lets in water and grit, which can quickly wear the inner tie rod and rack seals. Short trips to organise repair are fine, but don’t leave it—repairs get a lot pricier if the rack is damaged.

Do you need a wheel alignment after changing rackboots on a 2001 bB?

Yes, an alignment check is recommended. Even if the tie‑rod end threads are carefully marked and refitted, small differences can nudge toe out of spec. A quick alignment keeps the bB tracking straight and saves the tyres.
