2002 Toyota Caldina rack-boots: what they do and when to replace them

Based on Toyota’s technical literature for the T240-series Caldina (including AZT241W and ST246W) and Toyota’s Electronic Parts Catalogue, the 2002 Toyota Caldina uses a rack-and-pinion steering gear with protective bellows commonly listed as “steering gear boot” or “rack boot.” So yes—rack-boots are fitted and relevant on this model.

The rack-boots on a 2002 Caldina are the flexible bellows that seal each end of the steering rack, keeping road grime, water and grit out of the inner tie rod joints and the rack bar. They also help contain a light smear of grease around the inner joint. When these boots split or the clamps loosen, contaminants sneak in and the inner joints wear quickly, which can lead to steering play, noise, and even a WOF fail in NZ. Left long enough, the rack itself can cop damage, turning a cheap boot job into a pricey steering rack replacement.

As part of regular servicing, it’s smart to have the rack-boots inspected at the same time as tyres and brakes—say, every 10,000–15,000 kilometres or at each service interval. A quick visual from lock-to-lock will usually show if a boot is perished, torn, weeping, or not sitting under its clamps properly. If one side is gone, consider doing both. Use quality clamps (not cable ties) and a boot that matches the Caldina’s length and diameter, poorly sized “universal” boots can kink and fail early.

Replacement is straightforward: the tie rod end comes off, the old boot and clamps are removed, the inner joint ball is wiped clean and re-greased, then the new boot is slid on and secured with proper clamps. Marking the tie rod end position helps preserve toe, but it’s still best practice to book a wheel alignment afterwards to keep tyre wear in check and the steering tracking straight. For long life, avoid pressure-washing directly at the boots, and if the car often sees gravel roads or coastal air, inspect a bit more often. Genuine Toyota or reputable aftermarket EPDM boots tend to last longer and fit better on the Caldina’s rack than bargain-bin options.

• Typical tell-tales: grease sling on the inner guard, visible splits, loose clamps, light knocking over bumps, or failed WOF/rego inspection notes.

Popular questions about 2002 Toyota Caldina rack-boots

How can someone tell if their Caldina’s rack-boots are worn out?
They’ll often spot a split in the bellows, grease flicked onto the subframe or inner guard, or notice a bit of steering play. During a service or WOF, a tech will turn the wheel side-to-side and visually check for cracks, tears and loose clamps.

Do rack-boots affect wheel alignment?
The boots themselves don’t set alignment, but removal of the tie rod end to change a boot can shift toe. After any rack-boot or inner tie rod work, a wheel alignment is recommended to protect tyres and keep the Caldina tracking straight.

Is it safe to drive with a torn rack-boot?
It’ll usually still steer, but grit and water can quickly chew out the inner tie rod and rack seals. Driving far with a torn boot risks bigger, pricier steering repairs and can lead to a WOF fail. Replacing the boot sooner rather than later is the smart move.
