2005 Toyota Highlander/Kluger steering rack: purpose, care, and when to replace

Yes, the 2005 Toyota Highlander (sold as the Kluger in Australia and New Zealand) uses a hydraulic rack‑and‑pinion steering rack. This is confirmed by Toyota’s factory repair manual for the 2001–2007 platform, which details a rack‑and‑pinion steering gear and associated power steering hydraulics, and by Toyota’s Electronic Parts Catalogue listing a “Steering Gear Assembly (Rack & Pinion)” for this model (typical P/Ns include 44250‑48090 and 44250‑48091 for FWD/AWD variants). Aftermarket service manuals covering 2001–2007 Highlander/Kluger also provide procedures for rack removal, inner tie‑rod service, and boot replacement—further evidence that a steering rack is absolutely fitted.

On this Highlander/Kluger, the steering rack translates the driver’s input at the wheel into smooth, precise movement of the front wheels. It’s a compact, efficient design that keeps steering feel direct while the power‑assist hydraulics reduce effort for easy parking and confident highway tracking. Keeping it healthy is straightforward: use the correct fluid (Toyota specifies ATF meeting Dexron II/III for this era), keep an eye out for leaks, and replace worn boots and inner tie‑rods before they let dirt and water chew out the seals.

When servicing, a tech will typically check for play by rocking the front wheels, inspect the rack boots for tears or fluid, listen for clunks on light steering inputs, and look for seepage at the input pinion or end seals. Small leaks can sometimes be monitored, but once it’s weeping onto the subframe or the steering feels notchy, it’s time to plan a replacement or quality rebuild. Expect to support the subframe, disconnect the lines (new crush washers are a must), measure and match inner tie‑rod lengths, and torque everything to spec. Bleeding is simple: with the front wheels off the ground, cycle lock‑to‑lock several times (engine off, then on) while topping fluid, and check for aeration. A wheel alignment is mandatory afterward to protect tyres and ensure the wheel sits dead‑centre. If the vehicle is equipped with stability control, a steering angle/zero‑point calibration may also be required.

• Recommended fluid: ATF Dexron II/III (check the reservoir cap).
• Tell‑tale symptoms: torn boots, red fluid on the subframe, vague on‑centre feel, knocking on bumps.
• Good practice: replace outer tie‑rod ends with the rack, and book an alignment straight away.

Popular questions about 2005 Toyota Highlander/Kluger steering racks

What fluid should go in the 2005 Highlander/Kluger steering system?

Toyota specifies automatic transmission fluid meeting Dexron II or Dexron III for the power steering on this model, not universal “power steering fluid”. Using the correct ATF preserves seal life and proper assist feel.

Always confirm on the reservoir cap and owner’s manual. If the fluid looks dark or aerated, a gentle drain‑and‑fill or staged flush is worthwhile maintenance.

Do you need a wheel alignment after replacing the steering rack?

Absolutely. Any time the rack or tie‑rods are disturbed, toe settings will change. Driving without an alignment can scrub tyres and leave the wheel off‑centre.

Ask the shop to centre the wheel precisely. If the vehicle has stability control, a steering angle/zero‑point calibration may also be needed once alignment is complete.

How long does a 2005 Highlander/Kluger steering rack typically last?

Many original racks go well past 200,000 km, especially if the boots stay intact and the correct ATF is used. Age, rough roads, and fluid contamination accelerate seal wear.

Plan replacement when you notice persistent leaks, play in the inner tie‑rods, or a notchy feel. Catching boot damage early can extend the rack’s service life.
