2023 Subaru Outback Steering Rack — What It Does and How to Look After It

Technical sources confirm the 2023 Subaru Outback is fitted with a rack-and-pinion steering rack with electric power assist (EPS). This is documented in the Subaru Service Manual available via Subaru’s Technical Information System (STIS) for the BT-platform Outback, the MY23 Outback specification sheets for Australia and New Zealand that list “rack-and-pinion, electric power steering,” and Subaru’s genuine parts catalogues that show a complete steering gear (EPS) assembly for this model.

The steering rack on a 2023 Outback is the heart of the car’s direction control. It translates the driver’s steering wheel input into precise movement of the front wheels, while the electric assist motor delivers just the right helping hand at low speeds and backs off at highway pace. Compared with older hydraulic setups, the Outback’s EPS rack trims weight, cuts parasitic losses, and removes power-steering fluid from the service equation.

Day to day, there’s not much to fuss over, but it absolutely pays to keep an eye on the rack boots and tie-rod ends. During regular servicing (typically every 12 months or 15,000 km across AU/NZ), a tech should check for split boots, play in inner and outer tie rods, abnormal tyre wear, and any clunks over corrugations. Because it’s electric, there’s no fluid to flush—however, diagnostic scans can pick up EPS fault codes or a steering angle that’s drifted off centre after suspension work.

When replacement is needed—usually due to internal wear, heavy impact damage, water ingress, or persistent EPS faults—the job is more involved than swapping a pair of tie rods. The rack is removed from the subframe, new hardware is torqued to spec, and the steering wheel is centred. On refit, it’s important to perform steering angle and EPS calibrations with a proper scan tool (SSM is the Subaru factory choice), then finish with a four-wheel alignment. Many workshops use quality remanufactured EPS racks, just ensure they’re built to OE spec and come with a solid warranty.

• Signs it needs attention: on-centre wander, knocking over bumps, uneven tyre wear, assist warnings on the dash, or inconsistent steering weight.
• Good habits: rotate tyres on schedule, keep pressures right, and recheck alignment after any front-end repair.
• Typical costs vary widely, budget for professional diagnosis before committing to a rack.

Does the 2023 Outback use a hydraulic or electric steering rack?

It uses an electric power-assisted rack-and-pinion (EPS). There’s no power-steering fluid to change, and assist is delivered by an electric motor integrated with the rack, tuned for easy parking effort and stable highway feel.

What are common symptoms of a failing steering rack on this model?

Drivers may notice clunks over bumps, a loose or notchy feel around centre, uneven tyre wear, or an EPS warning lamp. After suspension work, a crooked wheel can also hint at alignment or calibration that needs sorting rather than a failed rack.

Is special calibration needed after replacing the steering rack?

Yes. A correct install includes centring the wheel, performing steering angle and EPS calibrations with a scan tool, clearing any fault codes, and finishing with a precise wheel alignment. Skipping these steps can leave the car pulling or the assist feeling off.
