Parts for your 2006 Toyota Caldina-Rack boots

2006 Toyota Caldina rack-boots: what they do and how to look after them

Rack-boots are absolutely used on the 2006 Toyota Caldina. Toyota’s Electronic Parts Catalogue for the T24 series (2002–2007) and the Toyota Repair Manual (Steering section) show a rack-and-pinion steering gear with bellows-type boots (also called gaiters) on both ends across models including AZT241/246 and ST246 GT-Four. So they’re relevant kit on every 2006 Caldina.

On this Caldina, the rack-boots seal the ends of the steering rack, keeping dust, water and road grit out while holding the correct grease around the inner tie rods. For hydraulic racks, a torn boot can let contamination in and help fluid leaks make a mess, for electric-assist variants, it still protects the rack and inner joints from wear. Left unchecked, split or perished boots can accelerate rack corrosion, chew out inner tie rods, and lead to vague steering or uneven tyre wear.

As part of regular servicing in Aus/NZ conditions, it’s smart to inspect the boots at each service or WOF check—look for cracks, oil soaking, loose clamps, or visible splits. If they’re damaged, replacement is straightforward with the right tools and a bit of patience.

• Jack up and support the front, remove the wheel, and mark the tie-rod position to help preserve toe.
• Crack the locknut, separate the outer tie-rod end from the knuckle, and unwind it.
• Remove the boot clamps, slide off the old boot, and check the inner tie rod and rack for play or leaks.
• Fit a quality boot with the breather/vent in the correct orientation, clamp it properly (use OE-style bands, not cable ties), then refit and torque to the workshop manual specs.

Always get a wheel alignment after the job—those few flats on the tie rod might still put toe out. If one boot has failed, consider doing both sides to keep things even. Use genuine or reputable aftermarket boots made for the Caldina’s rack diameter so the seals seat nicely.

Keeping the undertray in place (where fitted) and avoiding high-pressure washing directly at the boots will help them last. With a quick visual check every 10,000 km or so, most owners can spot issues early and keep the Caldina’s steering tight and trustworthy.

Popular questions about 2006 Toyota Caldina rack-boots

How can someone tell a Caldina’s rack-boots need replacing?
Typical giveaways are visible splits in the bellows, oil or grease weeping from the ends of the rack, loose or missing clamps, rubber that’s gone hard or perished, and new knocks or play when rocking the wheel. Uneven front tyre wear and slightly heavier or inconsistent steering can also hint that a boot’s failed and let grit in.

Is it safe to drive with a torn rack-boot?
Short distances may be unavoidable, but it’s not ideal. A torn boot can let water and road debris into the rack, potentially damaging seals and inner tie rods. On hydraulic racks, fluid can collect in or leak from the boot, worsening over time. Best bet: replace the boot promptly and book a wheel alignment.

Do new rack-boots require a wheel alignment?
Yes. Even if the tie rod is counted back on, tiny differences shift toe. A proper alignment protects tyres and ensures the Caldina tracks straight and steers crisply after the repair.
