Parts for your 2011 Toyota Bb-Rack boots

2011 Toyota bB rack-boots: what they do, where they fit, and how to look after them

Technical references confirm the 2011 Toyota bB does use rack-boots. The Toyota bB Repair Manual for the QNC20/21 series (Steering – Steering Gear & Linkage) shows a rack-and-pinion assembly with a bellows-type boot on each end of the rack. The Toyota Electronic Parts Catalogue (EPC) for the same model series lists “boot, steering rack” and associated clamps as service parts. These sources make it clear rack-boots are fitted and relevant to the 2011 bB.

On this model, the rack-boots (also called steering rack gaiters or bellows) shield the inner tie rods and the ends of the rack-bar from road grit, water, and general muck. Although the 2011 bB typically runs electric power steering (column-assist), the steering gear itself is still a rack-and-pinion setup. That means the bellows boots are essential to keep contaminants out, so the rack teeth, inner tie rod joints, and rack seals don’t cop a hiding and wear out early.

When the boots split or their clamps loosen, dirt and moisture can creep in and create corrosion or play in the inner tie rods. Drivers might notice a light knock over bumps, vague steering on-centre, or a notchy feel. There’s no power-steering fluid leak to look for on this bB, so visual inspection is king: check for tears, perishing, or grease flung out from the inner joint area.

As part of regular servicing, it’s smart to inspect the rack-boots at each service interval or roughly every 10,000–15,000 km. If a boot is damaged, replace it promptly—ideally in pairs. Use quality OEM or equivalent boots and proper crimp or ear clamps rather than cable ties. During replacement, the outer tie rod end is normally removed, so note the thread position or measure toe to keep alignment close. Even then, a wheel alignment check afterwards is good practice to avoid uneven tyre wear.

Handy tips for the 2011 bB:

• Clean the rack area before sliding the new boot on, so no grit gets trapped.
• Inspect inner tie rod joints while the boot is off, replace if there’s play.
• Fit the boot without twisting the bellows, and seat the boot lips fully in their grooves before clamping.

With a tidy set of rack-boots, the bB’s steering lasts longer and feels tighter, which is exactly what most owners want for city runs and weekend missions alike.

Popular questions about 2011 Toyota bB rack-boots

Does the 2011 Toyota bB actually have rack-boots?
Yes. The factory service manual and Toyota’s parts catalogue both show a bellows-type boot on each end of the steering rack. They’re there to keep grime out of the inner tie rods and rack ends.

How often should the rack-boots be checked or replaced?
Give them a look at every service or roughly every 10,000–15,000 km. Replace immediately if there’s a tear, perishing, or a missing/loose clamp. They’re inexpensive and can prevent far costlier rack or inner tie rod damage.

Will torn rack-boots cause a WOF or roadworthy fail?
Quite possibly. In NZ a WOF can be failed for damaged steering dust boots, and in Australia an RWC can be knocked back for the same. Even if it passes, torn boots should be sorted quickly to protect the steering gear.
