Parts for your 2018 Toyota Crown-Steering rack

2018 Toyota Crown steering rack — what it does and how to look after it

Technical documentation confirms the 2018 Toyota Crown (S220 series) uses an electric rack‑and‑pinion steering gear (EPS). This is detailed in Toyota’s Crown S220 Repair Manual steering section (Rack & Pinion Type, Electric Power Steering), the Toyota Global Newsroom 2018 Crown technical release describing EPS on the TNGA platform, and Toyota’s Electronic Parts Catalogue, which lists a steering gear assembly for the 2018 Crown. So yes — a steering rack is absolutely relevant and fitted to this model.

The steering rack converts the driver’s steering wheel input into precise left‑right movement of the front wheels. In the Crown’s case it’s an EPS unit, meaning an electric motor assists the rack instead of a hydraulic pump. That brings sharper response, better on‑centre feel and improved efficiency — handy around town and on long Kiwi and Aussie motorway runs.

Because it’s electric assist, there’s no power‑steering fluid to top up, and fewer hoses and seals to weep. Still, the rack, inner tie rods and outer tie‑rod ends are wear items over high kilometres, especially if the rack boots crack and let in grit. Keeping the front end tight helps tyre life and confidence under braking.

Good servicing looks like this: at each service, check the rack boots for splits, feel for play in inner and outer tie rods, and listen for clunks over small bumps. If the steering feels heavy or the car wanders, a quick inspection and a wheel alignment can save a set of tyres. On EPS Crowns, a steering warning light or assist that cuts in and out can flag electrical issues in the rack, torque sensor, or column.

• Warning signs: free play at the wheel, clunks, knocking, uneven tyre wear, steering‑angle off‑centre, EPS warning lamp, or intermittent assist.
• Replacement tips: quality OEM or reman racks only, replace torn boots and any loose tie‑rods, always carry out wheel alignment, and complete steering angle/torque sensor zero‑point calibration with a scan tool (e.g., Toyota Techstream). Supporting the front subframe correctly and torquing the intermediate shaft pinch bolt are essentials.

Looked after, an EPS rack in a 2018 Crown should run for many hundreds of thousands of kilometres with crisp, quiet operation.

Does the 2018 Toyota Crown actually have a steering rack?

Yes. The S220 Crown uses an electric rack‑and‑pinion steering gear (EPS). This is shown in the Toyota Crown S220 Repair Manual steering section and the Toyota parts catalogue listing for the steering gear assembly. The 2018 Toyota Global release for the Crown also notes EPS on its TNGA platform.

How long should a Crown steering rack last?

With intact boots and regular checks, many Crown racks go well past 200,000 km. Potholes, big wheels with low‑profile tyres, and neglected alignment can shorten that span. If there’s play, noise or an EPS warning, have it checked sooner rather than later.

What’s involved in replacing the rack on a 2018 Crown?

It’s a workshop job: the rack is removed from the front subframe, tie‑rods are set to baseline, then the system is reassembled, aligned, and the EPS zero‑point/steering‑angle calibration is performed with a scan tool. Always finish with a road test to confirm on‑centre feel and assist operation.
