Parts for your 2002 Toyota Crown-Rack boots

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

Yes, the 2002 Toyota Crown uses steering rack boots (also called bellows). Technical sources including the Toyota Electronic Parts Catalogue (EPC) for JZS171/JZS173/UZS171 models, and the Crown workshop manual’s Steering (ST) section, list “Boot, Steering Rack” components and clamps for the rack‑and‑pinion assembly (commonly referenced under Toyota part group 45535, e.g., 45535‑30110 and equivalents). Aftermarket catalogues from reputable suppliers also specify compatible rack boots for 2002 Crown variants, confirming the part is fitted from factory.

On a 2002 Toyota Crown, the rack boots seal the ends of the steering rack, keeping grit and water out while holding grease around the inner tie rod joints. That stops premature wear of the rack seals and pinion, keeps the steering smooth, and helps the power steering system stay clean. When a boot splits or perishes, road grime and moisture can chew out the inner joint and rack, leading to play, shudder and even fluid contamination.

For regular servicing, it’s smart to eyeball the boots every oil change or 10,000 km, and anytime after rough, muddy or coastal driving. If there’s oil misting, grease flung inside the wheel, or visible cracks, it’s time to act.

• Common signs they’re shot: visible tears or perishing, wetness or grease weeping, dirt packed inside folds, light knock on small bumps, or uneven tyre wear from toe shift.
• Roadworthy/WOF: a torn rack boot can fail a roadworthy in Australia and a WOF in New Zealand.

Replacement is straightforward with the right tools. Mark or count the turns when removing the outer tie rod end to keep toe close, but plan on a wheel alignment afterwards. Always fit new clamps (not cable ties), and use quality EPDM boots matched to the exact chassis code. While there, check inner tie rod end play and regrease the ball socket per workshop specs. If power steering fluid has entered a split boot, inspect the rack seals more carefully.

Best practice is to replace boots in pairs if one has failed, as age and exposure are usually similar side‑to‑side. It’s a low‑cost fix that protects a very expensive steering rack, and keeps the Crown tracking straight and feeling tight on Aussie and Kiwi roads.

How can someone tell if the 2002 Toyota Crown’s rack boots need replacing?

Look for cracks, splits, loose or missing clamps, or grease and fluid weeping from the folds. Steering that feels notchy, light knocks on corrugations, or sudden uneven tyre wear can also point to damaged boots letting grit in.

A quick torch check with the wheels turned full lock makes it easier to see the whole boot. If there’s contamination inside the boot, the inner tie rod and rack seals should be inspected as well.

Do rack boots on a 2002 Toyota Crown need a wheel alignment after replacement?

Counting the turns on the tie rod end will get toe close, but an alignment is still recommended. Even a small difference can affect tyre life and steering feel.

After any steering work, a proper alignment confirms toe is spot on and the Crown drives straight under brakes and at motorway speeds.

Which rack boot fits a 2002 Toyota Crown?

The Toyota EPC lists “Boot, Steering Rack” for 2002 Crown models (e.g., JZS171/JZS173/UZS171), commonly referenced under part group 45535. Many use a boot such as 45535‑30110 or equivalent, but exact fit varies by chassis and steering rack type.

Match by VIN or chassis code, or measure inner/outer diameters of the rack and tie rod seats. Choosing quality EPDM boots with proper metal clamps will last longer than generic one‑size bellows.
