2018 Toyota Vitz/Yaris Steering Rack — What It Does and How to Look After It
Referencing Toyota’s technical literature for the XP130/XP150 Vitz/Yaris platform (2017–2019), including the Repair Manual and New Car Features documents, the 2018 Toyota Vitz/Yaris uses an electric power-assisted rack-and-pinion steering gear (EPS rack). Parts catalogues for these models also list a complete rack assembly with inner tie rods and an integrated assist motor and control unit. So yes, a steering rack is fitted and absolutely relevant to this vehicle.
The steering rack on a 2018 Vitz/Yaris translates the driver’s steering wheel input into precise side‑to‑side movement of the tie rods, turning the front wheels. Because it’s electric power steering, an integrated motor and control module provides assist based on vehicle speed and steering torque, giving light effort around town and firmer feel on the motorway. That setup keeps things compact under the bonnet, ditches hydraulic fluid and hoses, and helps with fuel efficiency.
For owners, the rack’s job is all about straight tracking, predictable turn‑in, and consistent on‑centre feel. The rack, inner tie rods and outer tie rod ends work as a team, wear in any of them shows up as play, clunks, or uneven tyre wear. While there’s no power steering fluid to service, the EPS rack still needs periodic checks to stay sweet for the long haul.
- Inspection tips: look for torn rack boots, grease seepage, play at the inner tie rods, and any knocking over rough roads. Check for a steering wheel off‑centre after pothole or kerb strikes.
- Road feel: watch for heavy or notchy steering, poor return‑to‑centre, drift, or an EPS warning lamp on the dash.
If replacement is needed, a quality new or remanufactured EPS rack is the go. On this model the rack is bolted to the subframe, proper removal often involves supporting or lowering the subframe, so workshop gear and know‑how matter. After fitting, a wheel alignment is mandatory, and the EPS/steering angle zero‑point calibration should be performed with a scan tool. Many fasteners are torque‑critical, follow Toyota specs and replace any single‑use bolts as called out in the manual.
As part of routine servicing, have the steering and suspension checked every 20,000 km or annually in Australia and New Zealand conditions. Keep tyres at the right pressures, avoid smashing into kerbs, and sort wheel alignment promptly after any decent hit. That simple care keeps the rack happy, helps tyres wear evenly, and preserves that light, tidy Yaris steering feel.
- Common symptoms that need attention:
- Clunking or play felt through the wheel
- Uneven or rapid inner/outer tyre wear
- Steering wheel off‑centre or pull to one side
- EPS warning light or intermittent heavy steering
Does the 2018 Toyota Vitz/Yaris have a steering rack or a steering box?
It has a rack‑and‑pinion steering rack with electric power assist (EPS).
Toyota specifies an EPS rack on the XP130/XP150 Vitz/Yaris platform for 2017–2019.
A steering box isn’t used on this model, that’s more common on older or heavy‑duty vehicles.
The rack design gives compact packaging, light weight, and sharp steering response.
Electric assist replaces hydraulic pumps, fluid, and hoses, reducing maintenance.
At low speeds the EPS gives more assist, at higher speeds it firms up for stability.
Tell‑tales of a rack system include bellows boots and inner tie rods each side.
If the rack wears, drivers may feel play, clunks, or on‑centre looseness.
After impacts or big potholes, alignment and rack checks are a smart move.
Some markets share the same core rack, calibrations can vary by trim and region.
Rebuilds and reman racks are available, quality and calibration support are key.
Any rack replacement should finish with alignment and EPS zero‑point calibration.
How often should the steering rack be inspected, and what does replacement typically cost in AU/NZ?
Have it inspected every 20,000 km or at least once a year with routine servicing.
Check sooner after a kerb strike, deep pothole, or if tyres show odd wear.
Look for torn boots, grease seepage, and play at inner and outer tie rods.
Listen for knocks over bumps and feel for notchy or heavy steering.
Watch for an EPS warning lamp or a steering wheel that won’t self‑centre.
In Australia, typical replacement labour is about 3–5 hours in a workshop.
Parts vary widely: reman racks often run AUD ,600–,1,200, new can be higher.
Labour costs commonly sit around AUD ,400–,800 depending on location and shop.
Wheel alignment adds roughly AUD ,90–,150 and should always be included.
In New Zealand, expect similar hours, labour might be NZD ,450–,900.
Second‑hand racks are cheaper but riskier, ensure warranty and correct calibration.
Always finish with scan‑tool zero‑point calibration and a printout alignment.
