Parts for your 1998 Toyota Crown-Rack boots

1998 Toyota Crown rack boots — what they do and when to replace

Based on Toyota’s Electronic Parts Catalogue for the S150-series Crown (circa 1995–1999) and the Toyota Chassis/Steering Repair Manual for the same platform, the 1998 Toyota Crown uses a power‑assisted rack‑and‑pinion steering gear fitted with protective bellows—commonly called rack boots or gaiters—on each end. Note: the Crown Comfort taxi derivative of the era used a steering box and does not have rack boots, but the mainstream 1998 Crown sedan models do.

On the 1998 Crown, the rack boots seal and shield the inner tie rod joints and the rack bar from dust, water, and road grime. They also help keep any lubricant where it belongs. In Aussie and Kiwi conditions—think UV, heat, road grit, and the odd corrugated backroad—these flexible boots work hard and eventually crack, split, or go chalky.

As part of routine servicing, the boots should be inspected every service or at least every 10,000–15,000 km: look for cracks, tears, perished rubber, loose or missing clamps, and any wetness. If there’s power‑steering fluid pooling inside a boot or weeping out, that can point to an internal rack seal issue that deserves further diagnosis. Any torn boot should be replaced promptly to stop grit chewing out the inner tie rod and the rack itself.

Replacement is straightforward but best done with care. The tie rod end needs to come off the knuckle, so mark positions or count turns to keep alignment close, then have a proper wheel alignment done afterward. Use the correct style clamps rather than cable ties, and seat the boot fully in its grooves so it doesn’t twist or chafe on full lock. If play is felt at the inner joint, it’s smart to replace the inner tie rod while the boot is off. Boots are generally replaced in pairs, as age and exposure are usually the same on both sides.

Drivers who keep the rack boots tidy enjoy a lighter steering feel, reduced wear in the rack and inner joints, and fewer compliance headaches at WOF/roadworthy time. It’s a small, affordable bit of preventative maintenance that protects a far more expensive steering rack on a much‑loved 1998 Crown.

• Inspect rack boots at each service, replace at first sign of cracking, splits, or loose clamps.
• If a boot is torn, replace both sides and book a wheel alignment.
• Fluid inside a boot may indicate a leaking rack—have it assessed before it worsens.

Popular questions about 1998 Toyota Crown rack boots

Do all 1998 Crowns have rack boots?
Most 1998 Crown sedans (S150 series) do, as they run a rack‑and‑pinion steering gear. The Crown Comfort taxi variant used a steering box with linkages and therefore doesn’t have rack boots. Checking the VIN against a parts catalogue is the quickest way to confirm which steering setup a particular car has.

Is it safe to drive with a torn rack boot?
It’ll drive, but it’s not a good idea. A torn boot lets in dust and water, which can quickly wear the inner tie rod and the rack. That can lead to play, noise, and an expensive rack overhaul. It can also trigger a fail at WOF/roadworthy inspection. Better to sort the boot promptly and protect the rest of the steering gear.

How long do rack boots last on a 1998 Crown?
There’s no fixed interval, lifespan depends on climate and use. Many last well over 5–10 years, but once the rubber shows surface cracking or goes stiff and chalky, replacement is due. Regular inspection at service time is the best safeguard.
