Parts for your 2023 Subaru Impreza-Steering rack

2023 Subaru Impreza steering rack — what it does and how to look after it

Technical sources confirm the 2023 Subaru Impreza is fitted with an electric power-assisted rack-and-pinion steering rack, so the steering-rack is absolutely relevant on this model. Referenced sources include the Subaru Service Manual for Impreza MY2023 (Steering/Electric Power Steering sections), the MY2023 Owner’s Manual (Electric Power Steering), and the Subaru Genuine Parts Catalogue for MY2023 Impreza, all of which identify a steering gear (rack) assembly with integrated electric assist.

On the 2023 Impreza, the steering rack converts steering wheel input into precise side-to-side movement of the front wheels via the inner and outer tie rods. Because the assist is electric, there’s no hydraulic pump or fluid to service, which helps with efficiency and reduces maintenance. The rack also houses sensors and an assist motor that work with the vehicle’s control modules to deliver a consistent steering feel.

As part of regular servicing, the steering rack and linkages deserve a quick once-over. At scheduled services, a workshop should check for any play in the inner/outer tie rods, inspect rack boots for splits or grease seepage, listen for knocks over bumps, and note any uneven tyre wear or drifting that could indicate alignment or rack issues. If the EPS warning light appears or steering feels notchy or heavy, a scan for fault codes is worthwhile.

If a rack needs replacement, most owners will opt for a quality new or remanufactured assembly. Best practice includes:

• Replacing inner and outer tie rods and rack boots if worn, and using new single‑use fasteners where specified in the Subaru service data.
• Performing a wheel alignment after any rack or tie-rod work.
• Carrying out steering angle sensor/EPS neutral position learning with a scan tool, so safety systems behave as intended.

There’s no fluid service on this electric rack, but keeping tyres correctly inflated, suspensions in good nick, and alignments on point will help the steering rack live a long, quiet life. For most cars, a visual and functional check at each routine service is plenty, go sooner if there are clunks, play, or warning lights.

Popular questions

Does the 2023 Subaru Impreza use power-steering fluid?
No. It runs an electric power-assisted rack-and-pinion system, so there’s no hydraulic fluid to check or top up. If you spot oil under the front, it’ll be from another system, not the steering.

What are common signs the steering rack or tie rods need attention?
Play in the steering, front-end knocks, uneven tyre wear, pulling to one side, notchy feel on turn, or an EPS warning light. Any of these deserve an inspection and alignment check.

Do you need a wheel alignment after steering work?
Yes. After replacing the steering rack or any tie-rod ends, a full alignment is required. It’s also smart to reset the steering angle sensor/perform EPS neutral position learning with a scan tool.
