Parts for your 2015 Mazda Cx-5-Steering bushes

2015 Mazda CX-5 steering bushes: are they even a thing?

For the 2015 Mazda CX-5 (KE series), “steering bushes” aren’t a separate, replaceable part in the way many owners might expect. The vehicle uses an electric power-assisted rack-and-pinion steering gear (EPAS), and the rack is bolted to the front subframe with integral isolators rather than traditional, serviceable rubber bushes.

This isn’t just workshop folklore. Technical references back it up: the Mazda CX-5 (KE) Workshop Manual steering section details removal and installation of the steering gear without calling out any separate rack-mount bushes, the Mazda Electronic Parts Catalogue (KE, Steering/Group 32) lists the steering gear as an assembly with tie-rod components and boots, but no individual rack-mount bush part numbers, and Mazda’s AU/NZ service schedules don’t list steering bushes as an item for periodic replacement. Together, those sources indicate the CX-5’s steering gear mount insulators are built into the assembly and not intended to be serviced on their own.

Why would Mazda do this? Integrating the mounts into the EPAS unit tightens up manufacturing tolerances, helps control NVH (noise, vibration and harshness), and keeps the steering feel consistent over time. The trade-off is that if there’s excessive movement where the rack meets the subframe, the prescribed fix is inspection of the fasteners and subframe, and—if the mounting insulators are worn or damaged—replacement of the complete steering gear, not just a bush.

Owners chasing clunks, vibration, or a loose steering feel on a 2015 CX-5 are more likely dealing with other wear items:

• Front lower control arm rear bushes
• Stabiliser (sway) bar D-bushes and links
• Inner and outer tie-rod ends (ball joints)
• Strut top mounts or wheel bearings

So, while the term “steering bushes” pops up a lot online, it’s not a relevant service part for the 2015 Mazda CX-5. If the steering feels off, a proper inspection focusing on tie-rods, suspension bushes, and the rack assembly mounting torque will usually point to the real culprit. If free play is traced to the rack mounts themselves, the workshop guidance is to replace the steering gear assembly.

Popular questions about 2015 Mazda CX-5 steering bushes

Does a 2015 Mazda CX-5 have replaceable steering rack bushes?

No. On the KE-series CX-5, the EPAS steering rack mounts use integral insulators that aren’t listed as separate service parts. If movement is found at the rack mounts, Mazda’s documented repair path is to confirm subframe condition and fastener torque, then replace the steering gear assembly if required.

What noises get mistaken for worn steering bushes on a CX-5?

Common red herrings include front lower control arm bushes, sway bar D-bushes or links, and inner/outer tie-rod ends. A clunk over sharp bumps or a knock on lock is often a sway bar link or a tired lower arm rear bush rather than anything within the rack mounts.

What should be checked first if the steering feels loose?

Start with tyre pressures and wheel alignment. Then inspect inner and outer tie-rod ends, lower control arm bushes, and sway bar hardware. If all pass and there’s still detectable movement at the steering gear, verify rack-to-subframe bolt torque before considering rack assembly replacement.
