Parts for your 2013 Mazda Cx-9-Steering bushes

2013 Mazda CX-9 steering bushes

Short answer: steering bushes aren’t a thing on the 2013 Mazda CX-9. The factory steering gear (rack-and-pinion, hydraulic assist) is bolted directly to the front crossmember without separate, serviceable rack-mount bushes. This isn’t guesswork—Mazda’s Workshop Manual for the 2013 CX-9 (Steering System – Steering Gear and Linkage) specifies direct rack-to-subframe fastening with bolts and brackets, and the Mazda Electronic Parts Catalogue lists the gear assembly, fasteners and related hardware with no standalone “steering bush” components. Technical data aggregators used in AU/NZ trade workshops reflect the same parts breakdown.

Why no bushes? Mazda’s design controls noise, vibration and harshness (NVH) through the subframe isolation and the suspension bushes (control arms, sway bar D-bushes and links), rather than with compliant rack mounts. A solidly mounted rack gives more precise steering feel and reduces the chance of rack shift under load. Any “give” that helps ride comfort is handled elsewhere in the front-end.

So if there’s a clunk, vagueness, or vibration up the wheel on a CX-9, it’s almost always down to other wear points rather than “steering bushes”. Common culprits include:

• Inner tie rods (rack ends) and outer tie rod ends.
• Front lower control arm bushes (rear/hydraulic bushes are a frequent wear item).
• Stabiliser (sway) bar D-bushes and links.
• Intermediate steering shaft universal joint or column play.
• Engine/subframe mounts or loose subframe hardware.

Good servicing practice for a CX-9 with steering concerns is a front-end inspection on a hoist, checking tie rod play, ball joints, and control arm bushes under load, then confirming subframe and rack fastener torque as per the Mazda manual. If assist is noisy or inconsistent, check the hydraulic system (fluid level/condition, leaks at hoses and seals) and use the specified fluid shown in Mazda’s service literature. After any front-end work, book a proper wheel alignment—these big SUVs are sensitive to toe and caster changes.

Shopping for “steering bushes” in AU/NZ? What you probably want are front lower control arm bushes or sway bar D-bushes. These are widely available in OE rubber or polyurethane. Poly can sharpen response but may add a bit of NVH—great for a sportier feel, less ideal if the CX-9 is a family tourer tackling long kilometres.

Popular questions

Does a 2013 Mazda CX-9 have steering rack bushes?
No. According to the Mazda Workshop Manual and the Mazda EPC, the steering rack is rigidly mounted to the front crossmember with bolts and brackets, and there are no separate, serviceable rack-mount bushes on this model year.

What usually causes steering clunks or looseness if it’s not bushes?
Most commonly: worn inner/outer tie rods, tired front lower control arm bushes, or knocking sway bar links/D-bushes. Also check the intermediate steering shaft joint and subframe fasteners. A proper inspection will pinpoint which component has the play.

Can I fit aftermarket polyurethane steering rack bushes to a CX-9?
Not for the rack itself—there aren’t any to replace. Poly options do exist for control arm and sway bar bushes, which can tighten up the front-end feel, but expect a small increase in NVH compared with OE rubber.
