Parts for your 2001 Toyota Bb-Rack boots

2001 Toyota bB rack-boots: purpose, checks and when to replace

Based on Toyota’s own technical documentation, rack-boots are absolutely relevant to the 2001 Toyota bB (NCP30/NCP31). The Toyota bB Repair Manual (Steering – Rack and Pinion) depicts bellows-type boots on each end of the steering rack, and the Toyota Electronic Parts Catalogue for NCP30 lists a “Boot, Steering Rack” for both sides. That means this model is fitted with rack-boots from factory.

On a 2001 bB, the rack-boots (also called steering rack gaiters) are the flexible bellows that seal the ends of the rack-and-pinion housing and cover the inner tie rods. Their job is to keep dust, water and road grit out of the rack, hold grease around the inner joints, and allow the rack to move freely without contamination. On hydraulic power-steering versions, they also allow air to transfer side to side via a small breather, so pressure doesn’t build up in the boots. When they split or perish, grime gets in, grease gets out, and the rack and inner tie rods wear fast.

For servicing, it’s smart to inspect the rack-boots at every 10,000–15,000 km service or at least annually. If there are cracks, splits, or the rubber feels hard and chalky, replace them. Finding power-steering fluid pooled inside a boot usually means the rack’s internal seals are leaking, a new boot won’t fix that, and the rack may need overhaul or replacement.

• Warning signs: oily or torn boots, knocking over bumps, free play on the inner tie rod, uneven tyre wear, and gritty steering feel.
• Replacement tips: centre the steering, slide off old clamps, remove the boot without twisting the inner tie rod, and fit quality clamps rather than cable ties. Make sure any breather tube is reconnected so the boots can equalise pressure.
• Aftercare: turn lock-to-lock to check the boot doesn’t bind, torque the inner tie rod hardware to spec if disturbed, and book a wheel alignment if the tie rod has been removed or adjusted.

Good-quality rack-boots are inexpensive insurance for the bB’s steering gear. Fresh boots and clamps keep the inner joints happy, help the rack last longer, and save a pricey steering rack down the track. A tidy undertray and avoiding harsh solvents during cleaning also helps the boots live a longer life.

Popular questions about 2001 Toyota bB rack-boots

Does a 2001 Toyota bB actually have rack-boots?
Yes. Toyota’s bB (NCP30/NCP31) Repair Manual shows bellows boots on both ends of the rack-and-pinion, and the Toyota EPC lists “Boot, Steering Rack” for this model. They’re standard equipment.

How often should the rack-boots be inspected or replaced?
Have them inspected every 10,000–15,000 km or annually. Replace at the first sign of cracking, splitting, looseness at the clamps, or if they feel hard and brittle. If there’s power-steering fluid inside a boot, the rack seals are likely leaking and the rack needs attention beyond just boots.

Can a small split be taped up to get by?
Not recommended. Tape won’t seal properly, won’t flex like the boot, and will let in grit and moisture. Fit new boots and proper clamps, if the boot was oily inside, plan for rack repair or replacement.
