2005 Toyota ist rack boots — what they are and why they matter
Technical sources confirm the 2005 Toyota ist (NCP60/NCP61/NCP65) uses a rack-and-pinion steering gear fitted with bellows-style rack boots on both ends of the rack. The Toyota Electronic Parts Catalogue for the NCP60-series lists “Boot, Steering Rack” for left and right, and the Toyota steering system repair manual for the ist details inspection and replacement of the rack boots and clamp bands. So, yes — rack boots are definitely relevant on this model.
On the 2005 Toyota ist, rack boots (also called rack bellows) do a simple but vital job: they seal the ends of the steering rack, keeping dust, water, and grit out while holding the correct lubricant around the inner tie-rod joints. Whether the car has electric power steering at the column or a hydraulic setup, the rack itself still relies on intact boots to protect the rack bar, inner tie-rod sockets, and rack seals from wear and corrosion.
As part of routine servicing, they’re worth a proper look every 10,000–15,000 km or at each service. If a boot splits, moisture gets in, the inner joint can rust, and the rack can wear out quickly — that’s the kind of problem that turns into play at the wheel, noises over bumps, or even a WOF fail in NZ.
- Tell-tales they need attention:
- Visible cracks, oil misting, or splits in the bellows
- Grease flung around the inner guard or subframe near the tie rod
- Free play or knock from the inner tie-rod area
- Replace boots in pairs if one is damaged — the other won’t be far behind.
- Use proper OE-style stainless bands, avoid cable ties that can loosen or cut the rubber.
- Don’t pack the boot with grease, only a light smear on the sealing lips is recommended where specified by the manual.
- Mark tie-rod end positions on the threads before removal, but still book a wheel alignment afterwards — toe will change.
- Check the inner tie-rod ball joint for play while the boot is off, it’s the ideal time to renew it if loose.
Quality aftermarket or genuine boots for the NCP60-series are widely available, left and right are typically the same design on this platform, but it’s smart to confirm by VIN in the EPC. Fitted correctly with fresh bands and a post-job alignment, new rack boots help the ist steer sweetly and keep the rack happy for the long haul across Aussie and Kiwi roads.
Popular questions about 2005 Toyota ist rack boots
Do all 2005 Toyota ist models have rack boots?
Yes. The NCP60-series ist uses a rack-and-pinion steering gear with bellows-style rack boots on both ends. This applies regardless of whether the car has column-assist electric power steering or a hydraulic system, as the rack still needs dust and moisture protection.
How often should rack boots be replaced?
There’s no set interval — they’re replaced on condition. Inspect them at each service. If a boot is cracked, split, or oil-soaked, replace it straight away to prevent rack and inner tie-rod damage.
Do I need a wheel alignment after changing rack boots?
Yes. The outer tie-rod end usually comes off to slip the boot on and off. Even if the threads are marked, toe can shift, so a proper alignment is recommended to protect your tyres and restore straight-line stability.
