Parts for your 2019 Mitsubishi Asx-Steering rack

2019 Mitsubishi ASX steering rack — what it does and how to look after it

Technical sources confirm the 2019 Mitsubishi ASX is fitted with a steering rack. Mitsubishi’s factory Service Manual for ASX/RVR/Outlander Sport (Group 37: Steering) specifies an electric power-assisted rack-and-pinion unit, and the Mitsubishi ASA Electronic Parts Catalogue lists a complete “steering gear (rack-and-pinion), EPS” assembly for 2019 ASX variants. Independent data platforms such as Autodata/HaynesPro also describe the ASX steering as electric power steering (EPS) with a rack-and-pinion gear.

The steering rack on a 2019 ASX is the business end of the steering system, translating the driver’s wheel input into the left-right movement that turns the front wheels. On this model it’s an electric power-assisted rack-and-pinion design, with an assist motor and control unit mounted to the rack. That setup ditches hydraulic hoses and fluid, cuts engine drag, and gives consistent steering feel around town and on the open road.

Servicing is straightforward but important. There’s no power steering fluid to top up on this ASX, so the focus is on inspection and alignment. At each service, a good workshop will check the rack boots for splits, make sure the inner and outer tie-rod ends are tight and smooth, and look for free play that could show up as clunks, vibration through the wheel, or uneven tyre wear. If the EPS warning light pops up, a scan-tool check of the steering ECU helps pinpoint motor, torque-sensor, or angle-sensor issues.

When replacing the rack, a few key steps keep things sweet:

• Disconnect the battery and lock the steering wheel straight-ahead to protect the clock spring.
• Mark or measure toe settings, then book a proper four-wheel alignment after fitment.
• Use new rack boot clamps and tie-rod locknuts, torque fasteners to spec.
• Centre the rack before refitting the column, then perform steering angle sensor calibration with a scan tool.

Common signs it’s time for attention include a notchy feel, knock over bumps, wandering at freeway speeds, or the EPS light. Kerb strikes and potholes can tweak tie-rods and alignment, so if the ASX starts pulling left or right, get it checked early to save the tyres. With quality parts and the right setup, the steering rack should deliver years of quiet, precise operation across Aussie and Kiwi roads.

Does the 2019 ASX use electric or hydraulic power steering?

It uses electric power steering (EPS) with a rack-and-pinion gear. There’s no hydraulic pump, hoses, or power steering fluid to maintain. Assistance comes from an electric motor integrated with the rack, managed by a steering control unit.

What are the signs the steering rack or tie-rods need attention?

Look for a loose or notchy steering feel, clunks over bumps, the car wandering on the motorway, feathered or uneven tyre wear, or an illuminated EPS warning light. After a kerb strike or big pothole, get the alignment and tie-rods checked to prevent premature tyre wear.

How long does replacement take and what might it cost in AU/NZ?

Typical workshop time is around 3–5 hours including alignment and steering angle calibration. Costs vary with new vs remanufactured racks and local labour rates, but many owners in Australia and New Zealand will see a ballpark of $1,400–$3,000 fitted. A firm quote should include wheel alignment and any required calibration.
