Parts for your 2003 Toyota Caldina-Rack boots

2003 Toyota Caldina rack boots — purpose, care, and when to replace

Yes, the 2003 Toyota Caldina uses rack boots (also called steering rack gaiters/bellows). This is confirmed in the Toyota Electronic Parts Catalog (EPC) for the T24-series Caldina (2002–2007), which lists “Boot, Steering Rack” as a serviceable item on the steering gear assembly. The Toyota Repair Manual for the T24 platform also includes inspection and replacement procedures for the steering rack boots, reinforcing that they’re a standard component on this model’s rack-and-pinion steering.

On the Caldina, the rack boots sit at each end of the steering rack, covering the inner tie rods. Their job is simple but critical: they keep dust, water, and road grit out of the rack, and they help retain lubricant around the inner joint. If a boot splits, contaminants get in, grease gets out, and wear ramps up quickly on the inner tie rod and rack seals. It’s common to spot oily residue inside a torn boot on power-steering cars—handy as an early warning of an internal rack leak, but a sign the rack and boots need attention.

As part of regular servicing in Australia and New Zealand, it’s smart to inspect the Caldina’s rack boots at each service or at least every 10,000–15,000 km. Look for cracks, splits at the concertina folds, loose or missing clamps, and any sign of grease or power-steering fluid. If there’s damage, replace both sides as a pair using quality EPDM boots and proper ear or band clamps—cable ties won’t cut it long term.

Replacement is straightforward for a competent DIYer: mark the tie-rod end position, remove the outer tie-rod, slip off the old boot and clamps, clean the area, lightly grease the inner joint, then fit the new boot and secure the clamps. Refit the tie-rod end to the same count/mark to get it close, but always book a wheel alignment straight after—tyre wear and handling depend on it. If fluid is found inside the boot, plan for further diagnosis as the rack’s internal seals may be leaking.

Keeping the Caldina’s rack boots in good nick helps maintain light, precise steering, protects expensive steering components, and avoids WOF/roadworthy hassles from split gaiters.

Q: Does the 2003 Toyota Caldina have steering rack boots?

A: It does. The Toyota EPC and workshop manual for the T24-series Caldina specify “Boot, Steering Rack” on the steering gear. They’re standard bellows that protect the inner tie rods and rack ends.

Q: How often should the rack boots be checked or replaced?

A: Check them at every service or at least every 10,000–15,000 km. Replace immediately if there are splits, cracks, loose clamps, or signs of grease/fluid. If one side fails, it’s good practice to replace both.

Q: Will split rack boots fail a WOF/roadworthy in NZ or Australia?

A: Often, yes. Torn or leaking rack boots are commonly cited in WOF/roadworthy inspections because they allow contamination and can indicate steering wear. Fixing them promptly helps avoid a recheck.
