Parts for your 2018 Mitsubishi Eclipse cross-Steering rack

2018 Mitsubishi Eclipse Cross steering rack — what it does and how to keep it sweet

Technical sources confirm the 2018 Mitsubishi Eclipse Cross is fitted with a steering rack. The Mitsubishi Motors Workshop Manual for the GK-series (2018) lists an electric power-assisted rack-and-pinion steering gear (EPS), and the Mitsubishi ASA parts catalogue shows a steering gear/rack assembly and tie-rod components for GK1W/GK2W variants. Dealer specifications for the model also note electric power steering rather than a hydraulic steering box. So, yes — the steering rack is absolutely relevant on this model.

On the Eclipse Cross, the rack-and-pinion converts the driver’s steering input into a smooth left-right movement that turns the front wheels via the tie rods. The EPS motor provides assist, so there’s no hydraulic pump, hoses or fluid to service. That gives cleaner packaging, better efficiency and consistent on-road feel when it’s all in good nick.

Servicing is mostly about inspection and prevention. A tech will look for free play in the inner and outer tie-rod ends, torn rack boots, knocks over bumps, or any on-centre vagueness. They’ll also scan for EPS fault codes and check the steering angle sensor. Uneven tyre wear or a tendency to wander can point to wear or a previous knock to the rack.

If a steering rack needs replacing, it’s a straightforward but precise job. Expect new inner/outer tie rods as required, fresh boots and clamps, and new self-locking nuts where specified. Once fitted, a wheel alignment is non-negotiable. On EPS vehicles, a steering angle sensor zero-point and EPS calibration with a scan tool may be required to restore proper assist and stability-control behaviour. A quality OE or OE-equivalent rack is the safe bet, cheap units can introduce noise or inconsistent feel.

Handy tips for owners in Australia and New Zealand:

• Have the steering and front suspension inspected at least every 20,000 kilometres or annually, and after heavy pothole strikes or kerb hits.
• Keep an eye on rack boots, if they’re torn, grit and water will chew out the inner joints quickly — especially with coastal salt air.
• No power-steering fluid changes are needed on EPS, but do address any EPS warning light promptly and avoid pressure-washing electrical connectors on the rack.
• After any steering work, request a proper alignment printout and a road test to confirm on-centre feel.

Looked after this way, the Eclipse Cross steering rack should deliver crisp, reliable steering for many years and kilometres.

Popular questions about 2018 Mitsubishi Eclipse Cross steering racks

Does the 2018 Eclipse Cross use a steering rack or a steering box?
It uses an electric power-assisted rack-and-pinion steering rack (EPS). This setup is lighter, more efficient and gives nicer on-road feel than the old-school steering box designs.

Is there power-steering fluid to change on the Eclipse Cross?
No. The vehicle has electric power steering, so there’s no hydraulic fluid, pump or hoses. Service focuses on inspecting the rack boots, tie rods, alignment and running an EPS system check if needed.

Do I need a wheel alignment after steering rack or tie-rod work?
Definitely. Any time the rack, inner tie rods or outer tie-rod ends are disturbed, a full alignment is essential. On EPS cars, the technician may also perform a steering angle sensor reset and EPS calibration to keep assistance and stability control happy.
