Parts for your 2020 Mazda Cx-5-Steering rack

2020 Mazda CX-5 Steering Rack — Purpose, Care, and Service

Technical sources confirm a steering rack is absolutely fitted to the 2020 Mazda CX-5. The Mazda Workshop Manual for the KF series (2017–2021) lists an electric power-assisted, rack-and-pinion “steering gear and linkage”, the Mazda Electronic Parts Catalogue also shows the complete rack assembly, inner and outer tie-rod ends, and rack boots for the 2020 model. The Owner’s Manual references Electric Power Steering, which works directly on the rack-and-pinion gear. So a steering rack is relevant to this vehicle.

On a 2020 CX-5, the steering rack converts the driver’s hand input at the wheel into precise left-right movement of the front wheels. It’s a rack-and-pinion setup with an electric motor providing the assist, so there’s no hydraulic pump or power-steering fluid to worry about. That design keeps steering light at parking speeds and nicely weighted on the open road, improving efficiency and making day-to-day driving feel tidy and confident.

As part of regular servicing, a quick look over the rack and its related components is worthwhile. There’s no scheduled replacement for the rack itself, but technicians should check the rack boots for tears, inspect inner and outer tie-rod ends for play, and make sure the mounting points are snug. Because the system is electric, steering “flushes” aren’t a thing on this model—if someone’s trying to sell a power-steering fluid change for a 2020 CX-5, it doesn’t apply.

• Signs it’s time for attention:
  • Free play or vagueness on-centre, or the wheel not re-centring cleanly
  • Clunks/knocks on low-speed turns or over bumps
  • Uneven tyre wear and repeated alignment drift
  • Torn rack boots or grease seeping from tie-rod areas
  • EPS warning light or stored fault codes

If the rack or inner tie rods need replacing, using a quality new or expertly reconditioned unit is the go. The job should include new boots and clamps, and torqueing all fasteners to workshop-manual specs. After any rack or tie-rod work, a four-wheel alignment is mandatory. Because the CX-5 runs Electric Power Steering, the steering angle needs to be recentred and any EPS learn procedures completed with a capable scan tool (Mazda IDS/MDARS or equivalent). A proper road test—checking on-centre feel, return-to-centre, and no assist warnings—wraps the job.

Driven on Aussie and Kiwi roads, a well-looked-after CX-5 rack typically lasts for many years and plenty of kilometres. Keeping tyres properly inflated, avoiding big hits to kerbs, and getting prompt alignments after suspension work will help it go the distance.

Popular questions about 2020 Mazda CX-5 steering racks

Does the 2020 Mazda CX-5 use a steering rack or a steering box?
It uses a rack-and-pinion steering rack with electric power assist. There’s no old-school steering box on this model. The electric motor adds assist directly to the rack for crisp response and efficiency.

Is there power-steering fluid to change on a 2020 CX-5?
No. The 2020 CX-5 has Electric Power Steering (EPS) and doesn’t use hydraulic fluid. If you’re offered a power-steering fluid service for this model year, that service doesn’t apply.

Do I need an alignment or calibration after steering-rack or tie-rod work?
Yes. Any rack or tie-rod replacement needs a four-wheel alignment, plus a steering-angle reset/learn with a suitable scan tool so the EPS knows the new straight-ahead position. Skipping this step can leave the wheel off-centre or trigger warning lights.
