Parts for your 2005 Toyota Kluger-Rack boots

2005 Toyota Kluger rack boots: what they are, why they matter, and when to replace them

Technical reference check: The 2005 Toyota Kluger (XU20 series, incl. ACU25/MCU28) uses a rack-and-pinion power steering gear that is protected by bellows-style dust boots on each side of the rack. This is documented in Toyota service literature for the 2001–2007 Highlander/Kluger steering system and shown in the Toyota Electronic Parts Catalogue (EPC) as “Boot, Steering Gear” with matching inner/outer clamps. Aftermarket catalogues for the same model also list direct-fit steering rack boots. So yes—rack boots are fitted to, and relevant for, the 2005 Toyota Kluger.

On this Kluger, the rack boots (also called steering rack bellows) do a simple but vital job: they seal the ends of the steering rack and protect the inner tie rods and rack seals from dust, water, and grit. Keeping contaminants out prevents premature wear of the inner tie rod joints and helps the power steering rack last the distance, especially on Aussie and Kiwi roads where rain, road dust, and the odd gravel detour are part of the mix.

As part of regular servicing, the boots deserve a quick look whenever the front is on a hoist. A visual check every 10,000–15,000 kilometres (or at each scheduled service) is sensible. What the technician looks for is straightforward: intact rubber, no splits or perishing, proper seating on the rack and tie rod, and correct clamps. If a boot is torn, moisture and grit can get in and power steering fluid or grease can work its way out—both are red flags.

Replacement is usually affordable and can save a much bigger bill later. When a boot is damaged, many workshops recommend replacing the pair and inspecting the inner tie rods at the same time. OE-style ear clamps or quality stainless clamps should be used, cable ties are a last resort and can loosen. After refitting, a wheel alignment is recommended, because the outer tie rod is disturbed to swap the boot and the toe setting can shift.

Owners who drive on unsealed roads, tow, or see lots of city kerb strikes will benefit from more frequent inspections. If contamination has made its way inside the boot, flushing and checking the rack ends for play or corrosion is good practice. Leaving a split boot to “see how it goes” can lead to inner tie rod wear, steering knock, heavier steering, and eventually rack seal damage—none of which are cheap fixes.

• Typical signs a Kluger rack boot needs attention:
  • Visible cracks, splits, or oil-wet rubber on the boot
  • Grease or ATF mist on the inner tie rod or subframe
  • Clicking/knocking over bumps or a vague on-centre feel
  • WOF/RWC fail notes for torn or unsecured steering boots

Kept in good nick, quality rack boots help the 2005 Kluger steer quietly and track straight, and they protect the spendy bits in the steering gear for the long haul.

Popular questions about 2005 Toyota Kluger rack boots

What are the symptoms of a bad rack boot on a 2005 Toyota Kluger?

A failing boot often shows visible splits, oil or grease on the inner tie rod, or dirt packed inside the bellows. Drivers may notice light knocking over bumps or a slightly looser steering feel as inner tie rod wear sets in. Left long enough, contamination can accelerate rack seal wear and lead to power steering fluid leaks.

Will a torn rack boot fail a WOF (NZ) or RWC (AU)?

Yes, commonly. A torn or unsecured steering rack boot is typically flagged as a safety defect because it exposes critical steering components to contamination. Inspectors can require it to be replaced—and any associated play addressed—before issuing a WOF or RWC.

How often should Kluger rack boots be replaced?

They’re not a time-based service item, they’re replaced on condition. With regular inspections at each service, boots often last many years. High heat, age, road debris, and off-seal use shorten life. If one side fails, replacing both boots and checking the inner tie rods is sensible, followed by a wheel alignment.
