Parts for your 2010 Mazda Premacy-Steering bushes

2010 Mazda Premacy steering bushes — what they do and when to replace them

Based on technical references, the 2010 Mazda Premacy (Mazda 5, CW series) does use steering bushes. The Mazda Workshop Manual for the CW platform (Steering System – Steering Gear and Linkage) specifies “steering gear mounting rubber” for the rack, and the Mazda electronic parts catalogue lists these rubber mounts under the steering gear section. Reputable aftermarket catalogues for the CW Premacy/Mazda 5 also offer steering rack mounting bush kits, confirming they’re a serviceable item on this model.

On this Premacy, the steering bushes are the rubber mounts that secure the rack-and-pinion housing to the front subframe. Their job is to isolate vibration, keep the rack precisely located, and stop the steering from feeling vague or clunky over bumps. When the bushes age, harden, or split, the driver can notice a dull knock on rough roads, a shimmy through the wheel, or a wandering sensation that needs small corrections on the motorway. Excess play can also accelerate inner tie rod and outer tie rod end wear.

As part of routine servicing, it’s smart to inspect the steering bushes every 20,000–30,000 km, or at least once a year for Aussie and Kiwi conditions. A quick pry-bar check on a hoist will show if the rack shifts in its mounts. Look for cracks, oil-soaked rubber (common if there’s a power steering fluid leak), or ovalled inner sleeves. If there’s any movement or perished rubber, replacement restores steering precision and reduces noise and vibration.

Replacement is straightforward for a trained tech: support the rack, remove the rack-to-subframe bolts, swap the bushes, and torque everything to Mazda specs. On some vehicles, loosening the subframe or exhaust heat shields helps access. After refit, a wheel alignment is recommended, because even small subframe shifts can nudge toe settings. Where available, polyurethane upgrades can sharpen steering feel and last longer than OEM rubber, though they may transmit a touch more road feel—many owners consider that a fair trade for better response.

Tips for owners:

• Listen for front-end knocks on sharp bumps or driveway entries.
• Watch for uneven tyre wear and a pull that wasn’t there before.
• If replacing, consider doing tie rod ends at the same time to save labour and get a fresh alignment in one hit.

Popular questions about 2010 Mazda Premacy steering bushes

How do you tell if the steering bushes are worn on a 2010 Premacy?
A tell-tale sign is a dull clunk over potholes or speed humps and a slightly vague on-centre feel. On a hoist, a technician can lever the steering rack, if it shifts noticeably inside the mounts, the bushes are tired. Uneven front tyre wear and a steering wheel that needs frequent small corrections are common clues too.

Do the bushes need special tools to replace?
Generally, no special pullers are needed for the rack mounts on this model—just safe support, hand tools, and correct torque specs. Accessibility varies, some cars need the subframe loosened a touch for clearance. An alignment afterward is recommended.

Are polyurethane bushes worth it for Aussie/NZ roads?
For drivers who value sharper steering and longevity, polyurethane can be a great option. They’re more resistant to oil and heat and hold geometry well. Expect a little more road feel in the cabin compared with soft OEM rubber—most owners find the trade-off acceptable for daily driving.
