Parts for your 2016 Mazda Cx-5-Steering rack

2016 Mazda CX-5 steering rack — what it does and when to service it

Based on technical sources such as the Mazda Workshop Manual for the 2016 CX-5 (Steering System), the Mazda Electronic Parts Catalogue (listing the steering gear as a rack-and-pinion assembly), and the model’s Owner’s Manual (noting Electric Power-Assisted Steering), the 2016 Mazda CX-5 absolutely uses a steering rack. It’s an electric power-assisted rack-and-pinion setup, so there’s a conventional mechanical rack with an electric motor providing assist — no hydraulic pump or fluid.

On this CX-5, the steering rack translates the driver’s steering wheel input into precise wheel movement, while the electric motor and control module trim the effort and feel. It keeps the SUV tracking straight on motorways, helps with tidy turn-in on back roads, and keeps parking light and easy. The inner tie rods and outer tie rod ends connect the rack to the hubs, while protective bellows boots keep grit and moisture out of the rack’s moving bits.

As part of routine servicing, it’s smart to inspect the rack boots for tears, check the inner and outer tie rod ends for play, and make sure there’s no grease weeping from the boots. Because it’s electric, there’s no power steering fluid to top up or flush. If the steering feels notchy, there’s free play, it pulls or wanders, the tyres show uneven wear, or an EPS warning light pops up, it’s time for a closer look.

• Common symptoms of a tired rack or tie rods: clunks over bumps, vague steering on-centre, heavy spots while turning, or inconsistent return-to-centre.
• After any rack or tie rod work, a four-wheel alignment is a must.
• EPS calibration: after rack replacement, a scan tool is typically needed to initialise the steering angle/torque sensor and set the rack’s centre.

Replacement involves removing the old rack from the subframe, transferring any brackets or sensors as required, and installing a quality new or reman unit. In Australia and New Zealand conditions — lots of urban kerb knocks and rougher rural roads — inner tie rods often wear before the rack itself. Catching boot damage early can save the rack from grit ingress and extend its life well past 200,000 km. When in doubt, have a technician check for play with the wheels off the ground and confirm EPS fault codes before calling it a rack.

FAQs

Does the 2016 Mazda CX-5 have power steering fluid?
No. It uses Electric Power-Assisted Steering (EPAS), so there’s no hydraulic fluid or pump to service. If the steering feels off, it’ll be mechanical wear or an EPS sensor/control issue, not a fluid problem.

How long should a steering rack last on a 2016 CX-5?
With intact boots and gentle driving, many go 150,000–250,000 km or more. Frequent potholes, kerb strikes, or torn boots can shorten that, often showing up first as inner tie rod play.

Do I need an alignment after steering rack or tie rod work?
Yes. Any change to the rack or tie rods alters toe. A proper four-wheel alignment and EPS/steering angle reset with a scan tool will get it tracking straight and keep tyre wear even.
