Parts for your 2021 Mazda Cx-5-Steering bushes

2021 Mazda CX-5 steering bushes — are they actually used?

Short answer: no, a separate “steering-bushes” part is not used or serviced on the 2021 Mazda CX-5 (KF series). The model runs an electric power steering (EPS) rack that’s rigidly mounted to the front crossmember using bolts, with no replaceable rack-mount rubber bushes listed or called up in Mazda’s service procedures.

Technical references that back this up:

• Mazda CX-5 (KF, MY2017–2021) Workshop Manual — Steering Gear and Linkage: shows the EPS rack bolted directly to the front crossmember with specified torque and replacement bolts, but provides no procedure for replacing steering rack bushes, nor any inspection step for such bushes.
• Mazda Electronic Parts Catalogue (EPC) — Steering column/gear group for 2021 CX-5: lists the steering gear assembly, bolts, dust boots, inner/outer tie-rods and associated hardware, but no separate steering rack mounting bush part.
• Mazda EPS technical training materials: describe EPS racks being rigidly mounted to improve steering precision and on-centre feel, with NVH tuned via the subframe mounts, steering column joints/bearings and suspension bushings, rather than soft rack bushes.

Why it isn’t used: modern EPS systems benefit from a stiff, direct mount to give consistent assist calibration and steering feedback. Any compliance that would once have come from rubber rack bushes is now managed elsewhere — think subframe isolators, lower control arm bushes, sway bar D‑bushes, and the column’s bearings and intermediate shaft joints. On the KF CX-5, any minor isolation elements around the rack are integral and not serviceable on their own.

What owners should do instead: if there’s a knock, vagueness or vibration through the wheel, a technician should check the rack-to-subframe bolts for torque, inspect inner/outer tie-rods for play, confirm the intermediate shaft joints are free and tight, and look closely at front suspension bushes (especially lower control arm and sway bar bushes). Because the EPS rack doesn’t use hydraulic fluid, you won’t see power-steering fluid leaks — but split rack boots, loose hardware, or worn tie-rods can still cause symptoms often mistaken for “bush” issues.

If someone quotes “steering bushes” for a 2021 CX‑5, it’s worth asking for the Mazda part number. In most cases they’ll actually be referring to suspension bushes (control arm or sway bar) or recommending tie-rod work, not a rack-mount bush kit.

• Does a 2021 Mazda CX-5 have steering rack bushes?
  Not as a separate, serviceable part. The EPS rack is hard-mounted to the front crossmember with bolts. Mazda’s workshop procedures and parts listings for the KF CX‑5 don’t include replaceable steering rack bushes.
• What should be checked if there’s a steering clunk or play?
  Have a mechanic verify rack mounting bolt torque, inspect inner/outer tie-rods, check the intermediate shaft joints, and assess the front lower control arm and sway bar bushes. These items typically cause the symptoms people attribute to “steering bushes”.
• Can aftermarket steering bushes be fitted to tighten the feel?
  There’s no normal provision for aftermarket rack-mount bushes on the 2021 CX‑5. Because the rack is designed to be rigidly mounted, fitting non‑OE isolation parts isn’t recommended. Focus on tyre pressures, alignment, and the condition of tie-rods and suspension bushes for the best result.
