Parts for your 2018 Toyota Hiace-Rack boots

2018 Toyota HiAce rack boots — what they do and when to replace them

Yes, the 2018 Toyota HiAce (H200 series) uses steering rack boots. This comes straight from technical references including the Toyota Repair Manual for the H200 HiAce (Steering: Steering Gear & Linkage section) and the Toyota Electronic Parts Catalogue (EPC), which list a “Boot, Steering Gear” for 2018 KDH/TRH/GDH HiAce variants. Local compliance references such as NZTA’s VIRM and Australian state roadworthy guidelines also treat split or unsecured rack boots as a fail item, reinforcing that the vehicle is fitted with them and they matter for safety.

On a HiAce, rack boots (also called rack gaiters) are the concertina-style rubber sleeves at each end of the steering rack. Their job is simple but critical: keep dust, water, and road grit out of the inner tie-rod and rack seals, while letting the rack travel freely from lock to lock. Healthy boots help protect power-steering seals and grease, reduce wear on the inner joints, and keep the steering feel tight and predictable over the long haul.

For servicing a 2018 HiAce, it’s smart to inspect rack boots at every service or at least every 10,000–15,000 km. Look for splits, oil weep, perishing, or loose clamps. If a boot is torn, replace it promptly, driving with a split boot can let water into the rack, risking corrosion, noisy steering, and costly rack replacement. Replace boots in pairs where practical, use quality clamps (not generic cable ties), and position the boot neutrally with the rack centred so it doesn’t stretch at full lock. If the boot design calls for a light smear of rack grease at the inner joint, use only the recommended type and amount. After inner tie-rod or boot work, a wheel alignment is a good call.

• Signs it’s time: visible cracks/splits, grease fling on the crossmember, dampness from PS fluid near the boot, or a WOF/RWC advisory.
• Good practice: clean the rack area before fitting, seat clamps evenly, and recheck after a few hundred kilometres.
• If a boot failed due to oil contamination, chase the source (e.g., leaking PS seal) as part of the repair.

Keeping the HiAce’s rack boots in top nick is cheap insurance against rack wear, helps it sail through a WOF/RWC, and keeps steering feel spot-on for courier runs, site work, and long motorway stints.

Popular questions about 2018 Toyota HiAce rack boots

Do all 2018 HiAce models have steering rack boots?

Yes. H200-series HiAce vans sold in 2018 use a rack-and-pinion steering gear that has a boot (gaiter) at each end. This is supported by Toyota’s Repair Manual and EPC listings for KDH/TRH/GDH variants, which specify “Boot, Steering Gear” components for that model year.

How often should rack boots be checked or replaced on a 2018 HiAce?

Check them at each service or every 10,000–15,000 km. Replace immediately if split, perished, oily, or if clamps are loose. Many techs replace in pairs and perform an alignment after any inner tie-rod or boot work to keep the HiAce tracking true.

Will a split rack boot fail a WOF or roadworthy in NZ or Australia?

Usually, yes. NZTA’s VIRM and Australian roadworthy guidelines treat damaged or unsecured steering rack boots as a defect. A split boot can let in grit and moisture, so it’s flagged for safety and longevity of the steering gear.
