Parts for your 2009 Toyota Hilux-Rack boots

2009 Toyota Hilux rack boots — what they do and when to replace them

Based on technical sources, rack boots are absolutely fitted to the 2009 Toyota Hilux. Toyota’s Repair Manual for the AN10/AN20 series (KUN/GGN/TTN) covers rack-and-pinion steering with protective boots (often called bellows or gaiters), and the Toyota Electronic Parts Catalog lists “Boot, Steering Rack” for 2009 Hilux variants (common part references include 45535-0K010 and 45535-0K020). Aftermarket catalogues for the same models also specify direct-fit rack boots, confirming their use on this ute.

On a 2009 Hilux, the rack boots sit at either end of the steering rack, sealing and shielding the inner tie rods and rack bar from grit, water, and road splash. They’re the unsung heroes that keep the steering gear clean and lubricated, which helps the rack last longer and the steering feel stay tight and predictable — exactly what’s needed on corrugated roads, job sites, and weekend getaways.

Servicing-wise, they’re a simple check but a critical one. At every service or tyre rotation, a quick look under the bonnet and from underneath for split, perished, or oily boots is worthwhile. If a boot is torn, dust and water can be drawn into the rack with every turn of the wheel, accelerating wear, contaminating fluid/grease, and potentially leading to rack leaks and sloppy steering. Replace the boot promptly and inspect the inner tie rod and rack seals at the same time.

• Common signs a boot needs attention:
  • Visible cracks, tears, or loose clamps
  • Grease or oil weeping from the boot ends
  • Clicking or notchiness when turning, especially after wet or dusty use
• Good practice when replacing:
  • Do both sides together to keep wear even
  • Use quality clamps (spring or screw-type as specified), not cable ties
  • Re-grease the inner tie rod ball where the manual specifies
  • Set toe and get a wheel alignment afterwards

There’s no fixed kilometre interval for new rack boots — many will last well past 150,000 km — but Aussie and Kiwi conditions can be brutal. If the Hilux sees beach runs, creek crossings, or dusty worksites, more frequent inspections pay off. When fitting, match the boot profile and length to the rack and tie rod travel on the AN10/AN20 Hilux, and always follow the torque specs in the Toyota workshop manual for the tie rod lock nut and end.

Do all 2009 Hilux models use rack boots?

Yes. The 2009 AN10/AN20-series Hilux uses a rack-and-pinion steering assembly with protective boots across mainstream variants. If there’s any doubt, the VIN can be checked against the Toyota EPC, but for 2009 models, rack boots are the correct and relevant part.

How often should rack boots be replaced on a 2009 Hilux?

They’re replaced on condition rather than a strict interval. Inspect them at every service, replace immediately if torn, perished, loose, or oily. Vehicles used off-road, on farms, or around saltwater should be checked more often.

Will torn rack boots fail a WOF or roadworthy?

They can. In both Australia and New Zealand, damaged steering dust boots are a common defect. A split boot that exposes steering components to contamination is grounds for rejection, and it’s also a red flag for accelerated rack wear.
