2017 Toyota C‑HR Steering Rack — What it does and how to look after it

Yes, the 2017 Toyota C‑HR is fitted with a steering rack. Technical sources including Toyota’s Service Information (TIS) Repair Manual for C‑HR (NGX10/ZYX10) describe a rack‑assist Electric Power Steering (EPS) system with a rack‑and‑pinion steering gear. Toyota’s Electronic Parts Catalogue also lists a “steering gear assembly (rack and pinion), electric” for the 2017 C‑HR, confirming the part is relevant to this model.

On this C‑HR, the steering rack converts the driver’s steering wheel input into left‑right movement of the front wheels. An electric motor and control module are mounted to the rack to provide assist, so there’s no hydraulic pump, hoses or fluid. That gives lighter steering at low speed, a tidy feel at highway pace, and fewer service items under the bonnet.

Being an EPS rack, it’s largely maintenance‑free, but it still benefits from regular checks during scheduled servicing. A good workshop will inspect the rack boots for splits, check inner and outer tie‑rod joints for play, confirm the column coupling is secure, and scan the EPS for stored fault codes. There’s no power‑steering fluid to top up or flush on this model, so any oily residue around the rack area usually points to something else (for example, an engine or strut leak) rather than the rack itself.

Common signs the steering rack or related parts may need attention include:

• Notchy or inconsistent steering feel, or an EPS warning light on the dash
• Clunks over bumps or free play at the wheel from worn tie rods
• Steering off‑centre or uneven tyre wear that an alignment can’t correct

If replacement is required (after collision damage, excessive play, or internal EPS faults), the job calls for battery disconnection, careful centring of the rack, removal of the subframe fasteners, and correct torque on reassembly. A full wheel alignment is essential, and the EPS needs zero‑point/steering‑angle calibration with a scan tool. Many owners opt for a genuine or quality remanufactured rack, inner tie rods and outer ends can often be renewed separately if that’s all that’s worn. After installation, a short road test and, where applicable, EPS software updates will round things out. Look after the tyres and alignment, and the C‑HR’s steering rack should deliver years of fuss‑free service on Aussie and Kiwi roads.

Popular questions

Does the 2017 C‑HR use power‑steering fluid?
No. It runs an electric power steering (EPS) rack, so there’s no hydraulic fluid, pump or hoses to service. That means fewer leaks and less maintenance. If fluid is spotted around the front subframe, it’s likely from another system and worth checking properly.

How long should a C‑HR steering rack last?
With normal use and regular inspections, the rack typically lasts the life of the vehicle. Harsh roads, kerb strikes, or ignored torn boots can shorten its life by letting dirt or water into the inner tie rods and rack bar. Keeping wheel alignments in check and tyres properly inflated helps longevity.

Can the C‑HR’s EPS rack be repaired, or must it be replaced?
Inner and outer tie‑rod ends are commonly serviceable. Some specialists can recondition EPS racks, but many internal motor/sensor faults are addressed by replacing the rack assembly. After any rack work, a scan‑tool calibration and wheel alignment are required.
