2002 Toyota bB rack-boots: what they do and when to replace them
According to the Toyota bB Repair Manual (Chassis – Steering, covering NCP30/NCP31) and the Toyota Electronic Parts Catalogue for the 2002 model, the bB uses a rack-and-pinion steering gear fitted with bellows-type rack-boots on both ends. So yes—rack-boots are absolutely used on the 2002 Toyota bB, and they’re an important service item.
On this model, the rack-boots (also called steering rack bellows) seal the inner tie rods and the rack bar from dust, water, and road grit. They flex as the steering moves, keeping grease in and contamination out. If a boot splits, moisture and grit can chew out the inner tie rod and rack seals, leading to play in the steering, corrosion, and even power steering fluid leaks on hydraulic racks.
For routine servicing, a quick visual check of both rack-boots is smart practice—especially for cars doing lots of city kerb hops or gravel-road kilometres. A tidy, intact boot with secure clamps is what they want to see at a WOF or rego inspection. Any tearing, perishing, grease spray, or fluid inside the boot is a red flag.
- Signs they’re due: visible cracks or tears, loose or missing clamps, greasy sling on the crossmember, or light steering play and knocking over bumps.
- Good maintenance habits: inspect at each service, clean away built-up grime, and replace clamps that have lost tension.
When replacing, it’s worth choosing OE-quality or OEM-equivalent boots and proper crimp or ear clamps. If an inner tie rod has already worn from contamination, swap it at the same time. Many techs will count or mark the outer tie-rod position to keep toe close, but a proper wheel alignment is recommended after any steering work. During the job, they’ll check for rack-end play and, on hydraulic variants, look for fluid inside the old boot that might indicate a leaking rack seal.
There’s no fixed replacement interval—boots are condition-based items—but catching a split early is far cheaper than rebuilding a rack. For a 2002 Toyota bB, keeping those rack-boots tidy is a small job that pays off with tighter steering feel and fewer surprises at warrant time.
- How often should the rack-boots be checked on a 2002 Toyota bB?
They’re best inspected at every regular service. On cars that see gravel, coastal air, or lots of turning and parking, checking every 10,000–15,000 km helps spot cracking before it becomes a torn boot. - Do torn rack-boots fail a WOF in New Zealand?
Yes, a split or unsecured steering rack-boot can trigger a WOF fail because it compromises steering integrity and can lead to play or leaks. Replacing the boot and rechecking steering free-play usually sorts it. - Is a wheel alignment needed after replacing a rack-boot?
It’s strongly recommended. Even if the tie-rod end is counted back on, tiny changes affect toe. An alignment protects tyres and keeps the bB tracking straight.
