Parts for your 2017 Toyota Prius-Steering rack

2017 Toyota Prius steering rack: what it is, what it does, and how to look after it

Yes, the 2017 Toyota Prius uses a steering rack. Toyota’s own service information for the XW50-series Prius (2016–2018) describes an electric rack-and-pinion steering gear as part of its Electric Power Steering (EPS) system, and Toyota’s parts catalogue lists a rack-and-pinion “steering gear assembly” for this model. In other words, the steering rack is absolutely relevant to a 2017 Prius.

On this Prius, the steering rack converts the driver’s steering wheel inputs into precise movement of the front wheels, with an electric motor providing assist instead of a hydraulic pump. That setup cuts parasitic drag, improves efficiency, and gives consistent steering feel. It also means fewer fluid-related hassles, because there’s no power steering fluid to check or leak.

Owners of a 2017 Toyota Prius can expect the rack to be largely maintenance-free under normal use. Still, it’s smart to keep an eye—and ear—out for tell-tales that the steering gear or its related components need attention. A technician will usually inspect the rack boots and tie rod ends at every service interval and after any kerb strike or pothole hit.

• Listen for knocks, clunks, or creaks when turning at low speed.
• Watch for uneven tyre wear or a steering wheel that isn’t centred.
• Feel for play or a sticky, notchy sensation through the wheel.
• Check for torn rack boots or moisture/dirt ingress around the inner tie rods.

If the rack is damaged or has internal wear, replacement is the typical fix. Because this Prius uses EPS integrated with sensors and an electric assist motor, any steering gear replacement should be carried out by a technician familiar with Toyota EPS procedures, including steering angle neutral position and calibration routines. A wheel alignment is essential afterwards, and it’s common to replace outer tie rod ends at the same time if there’s wear.

As part of servicing, it’s wise to request:

1. Inspection of rack boots, inner and outer tie rods, and lower control arm bushes.
2. Check for free-play to Toyota’s spec and confirm steering angle offset is zero.
3. A road test over bumps and during tight turns to detect noise under load.

Driven gently, kept aligned, and protected from torn boots, the 2017 Prius steering rack generally delivers many kilometres of quiet, accurate steering with minimal fuss—very on-brand for a hybrid that’s built to go the distance.

FAQs

Does the 2017 Toyota Prius have a steering rack?

It does. The model uses an electric rack-and-pinion steering gear as part of its EPS system. Toyota’s workshop documentation for the XW50-series Prius specifies a rack-type steering gear with an integrated electric assist motor.

This design improves efficiency and reduces maintenance compared with older hydraulic systems, because there’s no power steering fluid to service.

What are common signs the steering rack needs attention on a 2017 Prius?

Clunks over bumps, a notchy feel when turning at parking speeds, uneven tyre wear, wandering on the motorway, or a steering wheel that won’t sit straight can all point to rack or tie rod issues. Torn rack boots are another red flag.

Any of these symptoms warrant an inspection, alignment check, and, if needed, EPS calibration after repairs.

How much does a steering rack replacement cost for a 2017 Prius in AU/NZ?

Costs vary with parts choice (genuine vs quality reman), labour time, and whether tie rod ends and alignment are included. As a ballpark, expect four-figure totals in AUD/NZD for supply, fitment, calibration, and alignment at a professional workshop.

Ask for an itemised quote that includes new rack boots, inner/outer tie rods if worn, wheel alignment, and EPS angle calibration.
