Parts for your 2008 Mazda Premacy-Steering bushes

2008 Mazda Premacy steering bushes — purpose, care and replacement

Technical references confirm steering bushes are relevant on this model. The Mazda Workshop Manual for the CR platform (Mazda5/Premacy, 2005–2010) and Mazda’s Electronic Parts Catalogue steering-gear diagrams show a rack-and-pinion unit mounted to the front subframe with rubber mounting bushes/insulators. These bushes locate the steering rack and isolate vibration, and on some variants they’re serviced as separate rubbers, on others Mazda supplies them with the rack assembly while aftermarket polyurethane options are available.

On a 2008 Mazda Premacy, the steering bushes keep the rack steady so the wheel’s input translates cleanly to the road. When the rubber hardens, splits or compresses with age, the rack can shift under load. The result is vague on-centre feel, a knock over bumps, or a shimmy when turning into driveways. Left too long, it can accelerate tyre wear and make the car wander, especially in crosswinds.

As part of regular servicing, it’s smart to inspect the steering bushes every 20,000–30,000 km or at WOF/rego time. Look for perished rubber, oil contamination from engine or rack leaks, and visible rack movement while an assistant rocks the steering. Don’t confuse sway-bar D-bushes with the steering rack mounts — both can knock, but rack movement is seen at the rack feet on the subframe.

Replacement is a straightforward but precise job. The rack is secured to the subframe with brackets, access typically requires safely supporting the vehicle, removing undertrays, and loosening or slightly lowering the front subframe to free the rack mounts. Bush style varies: some OEM bushes are bonded and not sold separately, pushing owners toward complete rack replacement, polyurethane bushes can be fitted in situ on many CR-chassis cars and sharpen up steering feel, though they may add a touch more vibration. Always torque the brackets to spec, recentre the steering, and book a wheel alignment afterwards. If the car has a steering pull, off-centre wheel, or rapid inner-edge tyre wear, checking the bushes alongside tie rods and lower control arm bushes is a no-brainer. Keeping the rack boots intact and fluids off the rubber will help the new bushes last longer in Aussie and Kiwi conditions.

• Common signs: clunks over bumps, vague steering, wandering, visible rack shift
• Service tip: inspect at each 10k–15k service and after any front-end impact
• After replacement: always perform a 4-wheel alignment

Popular questions about 2008 Mazda Premacy steering bushes

Do all 2008 Premacy models have steering rack bushes?
Yes. The CR-chassis Premacy (Mazda5) uses a rack-and-pinion mounted to the subframe via rubber bushes/insulators. Depending on build and market, Mazda may not list the bushes as separate OEM parts, but aftermarket suppliers provide serviceable replacements.

What symptoms point to worn steering bushes versus sway-bar bushes?
Worn steering bushes often show as play you can see at the rack feet while an assistant rocks the steering. You may feel looseness around centre or a knock as you load the wheel. Sway-bar bushes tend to clunk most on small, repeated bumps and don’t usually cause steering wander.

Should polyurethane bushes be used on a daily driver?
Poly bushes can sharpen response and hold alignment better, which many drivers like. On rougher roads they can pass a bit more vibration into the cabin. For a family runabout that sees city and motorway use, quality rubber or a comfort-grade poly is a solid choice.
