1998 Toyota Crown steering rack: what it is, why it matters, and when to service it

Based on technical sources like the Toyota Electronic Parts Catalogue for the S150-series Crown (1995–1999) and the factory workshop/repair manual for JZS151/JZS155 models, the 1998 Toyota Crown uses a power-assisted rack-and-pinion steering gear (commonly called a steering rack). Period specification sheets for the S150 Crown also list “rack & pinion, power” as the steering type, confirming the part is relevant to this vehicle.

On a ’98 Crown, the steering rack converts the driver’s steering wheel input into precise, linear movement of the front wheels. The hydraulic assist makes low-speed manoeuvres lighter while keeping the car planted and communicative on the open road. Because the rack sits low on the front subframe, it cops road grime, heat and age, so a bit of care goes a long way to keep the old girl tracking straight.

During regular servicing, it’s smart to check for tell-tales that the rack or its associated bits are getting tired:

• Oily residue or dampness around the rack boots or pinion area (possible seal weep)
• Free play, knock, or clunk through the column on bumps (inner tie rods or rack bush wear)
• Heavy or inconsistent steering, or a whine from the pump/reservoir (low/old fluid or aeration)
• Feathered tyre wear or a wandering feel (alignment off due to rack end wear)

Good practice on a Crown of this vintage includes inspecting rack boots for splits, checking inner and outer tie rod ends for play, and ensuring the rack mounting bushes aren’t perished. If fluid needs topping up or replacing, use the correct ATF-type power steering fluid specified on the reservoir cap or in the owner’s manual, and bleed the system after any work to avoid aeration.

When replacement is on the cards, a quality remanufactured rack with new seals and tested valves is typically the most time- and cost-effective path. Replace the inner/outer tie rod ends at the same time if there’s any doubt, then finish with a proper four-wheel alignment. Make sure the steering wheel is recentred, the column is locked at mid-point during install, and the clock spring isn’t stressed. With those boxes ticked, the 1998 Toyota Crown will feel tight, confident and nicely weighted — just as it should.

Popular questions about 1998 Toyota Crown steering racks

What are the most common signs the Crown’s steering rack needs attention?
Owners usually notice a light oil film at the rack boots, a clunk over small bumps, or extra play when rocking the wheel at standstill. Heavier steering, a moan from the pump, or tyres wearing unevenly can also point to rack-end or bush wear rather than the rack body itself.

Catch it early and you may only need boots, rack ends, or a reseal, leave it too long and internal wear can mean a full rack swap.

Is the 1998 Crown hydraulic or electric power steering?
It’s hydraulic. The S150-series Crown uses a belt-driven pump, fluid reservoir, hoses and a hydraulic rack. That’s why fluid condition, hose integrity and proper bleeding after service are so important on these cars.

Do I need an alignment after steering rack or tie rod work?
Yes. Any time the rack, inner tie rods, or outer tie rod ends are disturbed, the toe setting changes. A professional wheel alignment brings the geometry back into spec, protects tyres and restores straight-ahead feel.
