Parts for your 2005 Toyota Highlander-Rack boots

2005 Toyota Highlander rack boots — what they do and when to replace them

Yes, the 2005 Toyota Highlander uses steering rack boots. Technical sources that confirm this include the Toyota Repair Manual for 2004–2007 Highlander (Steering — Steering Gear &, Linkage sections covering rack boot/bellows inspection and replacement), Toyota’s Electronic Parts Catalog (listing “Boot, Steering Rack/Bellows” fitted to both sides of the rack for 2005 models), and mainstream parts catalogues from OE‑equivalent suppliers that provide rack boot kits for this specific vehicle. These references establish that rack boots are relevant and fitted as standard on the 2005 Highlander.

On this model, rack boots (also called steering rack bellows) are the accordion‑style rubber sleeves at each end of the rack‑and‑pinion housing. Their job is simple but crucial: keep grit, water and road splash out of the inner tie‑rod joints and rack seals, while keeping the factory grease in. By sealing the moving bits and allowing the tie rods to articulate freely, the boots help the steering feel consistent and protect the rack from premature wear or fluid leaks.

Because Aussie and Kiwi driving often includes corrugations, coastal spray and the odd gravel detour, boots harden and crack over time. Once split, they can let sand and water in, that can chew out inner tie rods and rack seals and, left long enough, turn into a rack replacement. During regular servicing, a quick look at the rack boots is cheap insurance.

• Replace the boots if you see splits, perishing, missing clamps, oil contamination, or if the boot is full of power‑steering fluid.
• Inspect every service or 10,000–15,000 km, and always after beach runs, flooded roads, or off‑road work.
• If one side has failed, it’s sensible to replace both boots as a pair.

When fitting new boots on a 2005 Highlander, choose OE or high‑quality aftermarket rubber that matches length and inner/outer diameters. Use proper stainless clamps rather than cable ties so the boot seals and can breathe as intended. Mark the outer tie‑rod position or count threads before removal to keep toe close, but budget for a wheel alignment afterwards — it’s the right way to protect your tyres. With the boot off, check inner tie‑rod play and the rack ends, if there’s any slop, sort it while you’re there. Torque fasteners to the Toyota spec from the service manual, and wipe away old grit before sliding the new boot on so you don’t trap abrasive muck. A clean install and a quick post‑service road test will keep the Highlander’s steering tight and drama‑free.
