Parts for your 2009 Toyota Crown-Rack boots

2009 Toyota Crown rack-boots: what they do and how to look after them

Based on Toyota’s own technical literature for the S200-series Crown (2008–2012)—namely the Toyota Repair Manual steering section and the Toyota Electronic Parts Catalogue—the 2009 Toyota Crown uses bellows-type steering rack boots (also called rack gaiters). So yes, rack-boots are absolutely relevant on this model, whether it’s running hydraulic or electric power steering.

On the 2009 Crown, the rack-boots sit at each end of the steering rack, sealing and shielding the inner tie rods and rack bar from water, road grit, and dust. They help keep the correct lubrication where it belongs and allow the rack to move freely without contamination. If a boot splits, grit and moisture can chew out the inner tie rod and the rack’s surface, which can quickly snowball into stiffness, play at the wheel, or a pricey steering rack replacement. On hydraulic racks, fluid weeping into a boot is also a tell-tale of an internal seal leak that needs attention.

Service-wise, it’s smart to eyeball the rack-boots at every routine service or at least every 10,000–15,000 km. Look for surface cracking, splits in the concertina folds, loose or missing clamps, and any sign of grease or oil contamination. If a boot is torn, replace it promptly—ideally both sides as a pair. Use quality OEM-style boots and new clamps, and don’t pack the boot with grease or sealant, it needs to breathe as designed.

When replacing a boot, mark the tie-rod locknut position, count the turns off/on, or better, measure toe before and after. Even with care, a wheel alignment afterwards is the right move. Make sure the boot isn’t twisted when fitted and that any breather feature is clear. Correctly seating the small and large ends of the boot and tightening the clamps to spec keeps the seal intact. Typical workshop time is about an hour a side, plus alignment.

Left unattended, a split rack-boot can lead to corrosion, noisy clunks over bumps, vague steering, and potential WOF/roadworthy issues in NZ and Australia. Staying on top of boot condition is cheap insurance against an expensive steering rack down the track.

• Inspect at every service or 10,000–15,000 km
• Replace torn boots promptly—preferably in pairs
• Use new clamps and book a wheel alignment after

Popular questions about 2009 Toyota Crown rack-boots

Does the 2009 Toyota Crown use rack-boots?
Yes. Toyota’s service manuals and the Electronic Parts Catalogue for the S200-series Crown specify bellows-type steering rack boots on this model. They’re standard kit on both hydraulic and electric rack-and-pinion setups.

How often should the rack-boots be checked or replaced?
A quick visual check at each service—or every 10,000–15,000 km—is wise. Replacement isn’t mileage-based, it’s condition-based. If there’s cracking, a split, or contamination inside the boot, replace it straight away to protect the rack and inner tie rod.

Do you need a wheel alignment after replacing rack-boots?
Yes, it’s recommended. Even if the tie-rod length is carefully marked, removal and refit can nudge toe settings. A post-repair alignment keeps tyre wear even and steering feel bang on.
