Parts for your 2003 Toyota Caldina-Steering rack

2003 Toyota Caldina steering rack — what it does and how to look after it

Technical sources including Toyota’s Electronic Parts Catalogue (EPC, PNC 44250 Steering Gear Assy – Rack & Pinion) and the T24-series Caldina workshop literature confirm the 2003 Toyota Caldina (AZT241/ZZT241/ST246, including GT-Four) uses a hydraulic, rack‑and‑pinion steering rack. Toyota’s New Car Features material for the T24 platform also describes a conventional rack-and-pinion layout with power assist, not electric power steering. So yes — a steering rack is relevant and fitted to this model range.

On a 2003 Caldina, the steering rack converts the driver’s wheel input into precise left-right movement of the front wheels. It’s the heart of the steering system, providing direct feel and accurate tracking, which suits everything from day-to-day commuting to the ST246’s grippier, all-wheel-drive setup. The hydraulic assist reduces steering effort at low speeds while maintaining good road feel on the open road. Inner tie rods (rack ends) and outer tie rod ends connect the rack to the knuckles, and protective boots keep the internals clean and lubricated.

As part of servicing, it’s worth giving the steering rack a regular once-over. Look for power steering fluid seepage at the rack seals or from under the bellows boots, a notchy or heavy feel at the wheel, play or clunks over bumps, and uneven tyre wear. Check fluid level and condition — Toyota specifies ATF (Dexron III) or Toyota PSF as applicable — and keep an eye on the pump and hoses because leaks up top will drip down and mimic a rack fault. Inspect rack boots for tears, and check inner/outer tie rods for free play, even a small amount can throw out alignment and chew tyres.

If replacement is on the cards, many owners choose a quality reconditioned rack with new seals and bushings. Replace tie rod ends and rack ends at the same time if they’re worn, fit new boots, and finish with a proper wheel alignment. It’s smart to flush the system and refill with fresh fluid (about a litre typically covers a drain-and-fill, more for a full flush). After installation, recheck for leaks and re-torque fasteners once the car’s done a few kilometres. A well-sorted rack keeps the Caldina steering light, accurate, and confidence-inspiring on Kiwi and Aussie roads.

Does the 2003 Caldina use electric or hydraulic power steering?

It uses a hydraulic rack-and-pinion system across the range, including the ST246 GT-Four. There’s no electric power steering on the 2003 Caldina.

What fluid should go in the Caldina’s power steering?

Use ATF Dexron III or Toyota Power Steering Fluid as specified under the bonnet or in the owner’s manual. Keep the level between the MIN and MAX marks and avoid mixing unknown fluids.

Can the inner tie rods (rack ends) be replaced without changing the whole rack?

Yes. Inner tie rods and outer tie rod ends are serviceable items. If the rack itself isn’t leaking or worn, replacing these and the boots, then aligning, is a cost-effective fix.
