Parts for your 1993 Toyota Caldina-Rack boots

1993 Toyota Caldina rack boots — purpose, care, and when to replace

Rack boots (also called steering rack gaiters) are absolutely fitted to the 1993 Toyota Caldina. Technical references that confirm this include the Toyota Electronic Parts Catalogue (EPC) for ST19#/CT19#/ET19# Caldina models (1992–1997), which lists a “Boot, steering rack” under the steering gear (commonly referenced part numbers such as 45535-12050 and 45535-20030). Toyota chassis service manuals for this era also specify periodic inspection of steering rack boots during routine maintenance, and NZ/AU roadworthiness guidance treats split rack gaiters as a safety defect. All of that points to rack boots being relevant and required on the ’93 Caldina.

On a 1993 Caldina, the rack boots sit at each end of the steering rack, covering the rack bar and inner tie rods. Their day job is to keep dust, water, and road grit out of the rack while holding the correct grease where it needs to be. On power-steered cars, the boots aren’t meant to hold fluid, if fluid pools inside a boot, that’s a red flag for an internal rack seal leak.

It’s smart to eyeball the boots at every service or at least every 10,000–15,000 km. Look for splits, perishing, clamp damage, or oily residue. Any crack lets in grit that can chew out the inner tie rod and rack bushings, leading to play in the steering, uneven tyre wear, and costly rack repairs.

Replacing a perished rack boot is a straightforward job for a competent home mechanic, though an alignment check afterwards is a must. Typical process:

• Mark the tie rod end and lock nut position to preserve toe setting.
• Remove the outer tie rod end, slide off old clamps and the damaged boot.
• Wipe the rack bar clean, add the specified light grease if required, then slide on the new boot with fresh clamps.
• Refit the tie rod end to the original mark, torque to spec, and book a wheel alignment.

Quality matters. Go for OEM or reputable aftermarket boots made from proper EPDM rubber, cheap vinyl boots often split early in Aussie/Kiwi sun and heat. If a boot is torn and there’s power steering fluid present, don’t just swap the boot—have the rack inspected, because that points to a failing internal seal. Keeping the rack boots in good nick is a low-cost way to protect the Caldina’s steering gear and keep it driving tight and true.

Popular questions about 1993 Toyota Caldina rack boots

How can someone tell if a rack boot is failing on a 1993 Caldina?
They’ll usually spot cracks, splits, or missing clamps, sometimes with a light knock over bumps or grease/dirt buildup around the inner tie rod. If the boot is swollen or wet with power steering fluid, that suggests an internal rack leak that needs deeper attention.

Can rack boots be replaced without pulling out the steering rack?
Yes. On the Caldina, the outer tie rod end is removed and the boot slides off the rack end. It’s a driveway-friendly job with basic tools, but an alignment check afterwards is recommended to make sure the toe setting is bang on.

How often should rack boots be inspected?
Check them at every service or at least annually. Given local conditions in Australia and New Zealand—UV exposure, heat, and road grime—regular inspection helps catch perishing early and saves the steering rack from avoidable wear.
