Parts for your 2020 Toyota C-hr-Steering rack

2020 Toyota C‑HR Steering Rack — Purpose, Care and Replacement

Based on Toyota’s own technical literature — the Toyota C‑HR (AX10/AX50) Repair Manual, Steering section: Electric Power Steering (Rack &, Pinion) — and Toyota’s Electronic Parts Catalogue, which lists a steering gear (rack‑and‑pinion) assembly for the 2020 model, the 2020 Toyota C‑HR is fitted with an electric power steering rack. It’s not steer‑by‑wire and it doesn’t use hydraulic power steering fluid.

On the C‑HR, the steering rack converts steering‑wheel rotation into side‑to‑side movement that turns the front wheels via the inner and outer tie‑rods. Being electric power assisted (EPS), the assist motor and control unit are integrated with the rack, giving light effort around town and a steadier feel on the open road. It’s compact, efficient, and there’s no fluid to top up or leak like older hydraulic systems.

There’s no scheduled replacement interval for the rack itself, but it should be inspected at routine services. Good workshops in Australia and New Zealand will:

• Check for play or clunks through the column, rack and tie‑rods, and look for torn rack boots.
• Confirm smooth steering with no “notchy” spots and no EPS warning light on the dash.
• Measure tyre wear patterns and set a wheel alignment if the steering wheel isn’t straight or toe is out.

If the steering rack needs replacing — usually due to impact damage, excessive internal wear, or electrical faults in the EPS unit — expect a more involved job than swapping tie‑rod ends. The front subframe may need to be lowered for access. The battery is disconnected, the column is uncoupled, the rack is removed, and new stretch‑type fasteners (where specified) are torqued to spec. After installation, a wheel alignment is mandatory and the EPS requires zero‑point/centre calibration with a scan tool (e.g., Toyota Techstream). A short road test with a lock‑to‑lock sweep helps the system relearn steering angle limits.

As for driving habits, avoiding kerb strikes and big potholes will greatly extend the life of the rack and tie‑rods. If the C‑HR develops free play, a knock over bumps, a crooked steering wheel, heavy or inconsistent assist, or the EPS light appears, it’s time for a proper check. Catching issues early usually keeps the repair to boots, inner/outer tie‑rods, and an alignment rather than a complete rack replacement.

Popular questions

Does the 2020 Toyota C‑HR have a steering rack?
The 2020 C‑HR uses an electric rack‑and‑pinion steering rack (EPS). This is confirmed in Toyota’s C‑HR Repair Manual and the Toyota Electronic Parts Catalogue. It’s not a steer‑by‑wire setup and it doesn’t use hydraulic power steering fluid.

How often should the C‑HR steering rack be serviced?
There’s no fluid service or scheduled replacement for the rack. At regular services (about every 10,000 km or 12 months), a technician should inspect the rack boots, tie‑rods and steering play, and set a wheel alignment if needed. After any rack replacement, a scan‑tool calibration of the EPS centre point is required.

What are signs a C‑HR steering rack may be worn?
Common symptoms include free play or clunks felt through the wheel, notchy or heavy steering, uneven tyre wear, a steering wheel that won’t sit straight, or an EPS warning light. Because it’s electric, there’s no power steering fluid leak to look for.
