Parts for your 2018 Toyota Crown-Steering rack

2018 Toyota Crown steering rack — what it is, why it matters, and how to look after it

Based on technical sources, the 2018 Toyota Crown does use a steering rack. Toyota’s Repair Manual (TIS) for the S210/S220 Crown series identifies a rack-and-pinion electric power steering (EPS) “Steering Gear” assembly. Toyota’s 2018 Crown launch information also notes rack-assist EPS with Variable Gear Ratio Steering (VGRS) on some grades, and the Toyota Electronic Parts Catalogue lists a Steering Gear Assembly (e.g., 44250‑xxxxx) for 2018 Crown variants. So a steering rack is absolutely relevant on this model.

The 2018 Toyota Crown runs a rack-and-pinion electric power steering (EPS) unit, so the steering rack is the heart of the whole setup. Its job is simple but critical: convert the driver’s turn at the wheel into precise left-and-right movement at the front wheels, with the EPS motor adding assist so it feels light at low speeds and settled at motorway pace. On some grades there’s Variable Gear Ratio Steering, tweaking the rack’s response for sharper parking and steadier cruising.

Servicing wise, the rack itself doesn’t have a fluid to change because assist comes from an electric motor rather than a hydraulic pump. That said, it still benefits from regular checks. Every 10,000–15,000 km, a technician should inspect the rack boots for splits, check inner and outer tie-rod play, and verify there’s no impact damage from kerbs or potholes. While the bonnet’s up, they’ll scan the EPS for fault codes and perform a steering angle calibration if the battery has been disconnected or a wheel alignment was recently done.

Noise, free play, or a pull under braking are the early flags. Knocks over sharp bumps often point to worn inner joints, while sticky on-centre feel can indicate rack gear wear or EPS motor issues. If the boots have torn, grit can score the rack bar quickly, so catching that early saves money. Don’t forget tyres: uneven wear or mismatched pressures can mimic a rack fault, so rule those out first.

Replacement is straightforward for a pro but fiddly on the driveway. The front subframe is usually supported and the rack slipped out, then new self-locking fasteners are torqued to spec. After refitting, a four-wheel alignment is mandatory, and the EPS needs a zero-point calibration. If the car has VGRS, a proper initialisation routine is essential. Genuine or high-quality remanufactured racks are worth it in NZ and Australia, they tend to last longer and play nicely with the Crown’s electronics. Fresh tie rods and new boots at the same time are cheap insurance, and a post-repair road test on varied surfaces confirms the steering feels taut and tracks straight as expected.

Q: How long does a 2018 Toyota Crown steering rack usually last?

In normal Aussie and Kiwi driving, a well-looked-after EPS rack commonly reaches 150,000–250,000 kilometres. City kerbs, big potholes, and oversized wheels can shorten that window.

Keeping tyres matched and correctly inflated, doing regular alignments, and replacing split boots early are the biggest lifespan boosters.

Q: What are the signs the Crown’s EPS rack needs attention?

Tell-tales include clunks over sharp bumps, vague or notchy on‑centre feel, a steering wheel that doesn’t self-centre well, or uneven tyre wear that keeps returning after alignment.

Warning lights for EPS, or a change in steering weight between trips, also deserve a scan and a physical check of the inner and outer tie rods and rack boots.

Q: Can the steering rack be repaired, or does it need full replacement?

Often, inner or outer tie rods and boots can be replaced without changing the rack. If the rack bar is scored, the EPS motor or torque sensor is faulty, or there’s excessive internal wear, a quality new or remanufactured rack is the smart fix.

After any rack work, insist on a four-wheel alignment and EPS zero-point calibration, VGRS models also need proper initialisation to restore correct steering feel.
