Parts for your 2003 Mazda 6-Steering bushes

2003 Mazda 6 steering bushes — what they do and how to look after them

Yes, a 2003 Mazda 6 runs steering bushes. Technical references that cover the GG/GY-platform car — including the Mazda Workshop Manual (Steering System: Rack-and-Pinion, Mounting) and Mazda EPC parts catalogues — show the steering gear is mounted to the front crossmember using rubber mounting bushes. Aftermarket technical catalogues from brands like Nolathane and SuperPro also list rack-mount bush kits for 2002–2008 Mazda 6, confirming fitment.

On this Mazda, the steering bushes secure the rack-and-pinion to the subframe while isolating vibration. They keep the rack located under braking and cornering loads so the wheel alignment stays true and the steering feels tight. When they age, soften from oil exposure, or split, the rack can shift slightly — that’s when the steering starts to feel vague or clunky.

• Common signs they’re tired: a knock over speed humps, a thud when turning into a driveway, vague on-centre feel, or steering that “tramlines”. You might also notice accelerated inner or outer tyre wear.
• Inspection tips: at service time, check for cracks, perishing, or oil soaking on the rack mounts, lever the rack gently to see if there’s excess movement, and verify the rack-mount bolts are tightened to the Mazda manual’s torque spec.

Replacement is straightforward for a trained tech: safely support the car, relieve load on the subframe, remove the rack-mount bolts, press out the old bushes, press in new items (rubber OE or polyurethane), then torque the hardware to spec. Because the rack’s location is disturbed, a wheel alignment is recommended straight after. Plan on freshening any weeping power-steering hoses first — leaked fluid can prematurely soften rubber bushes.

Choice of material depends on how it’s driven. OE-style rubber keeps it quiet and comfy for daily duties. Quality polyurethane bushes sharpen steering feel and reduce rack movement, great for spirited driving, but can transmit a touch more road feel and noise. For Aussie and Kiwi roads that mix coarse chip with city commutes, many owners stick with rubber, enthusiasts often opt for poly.

As part of routine servicing, it’s smart to eyeball the steering bushes every 10–15,000 km, or any time there’s a new knock or alignment drift. Done properly with the right tools and factory torque values from the Mazda Workshop Manual, fresh bushes restore that direct, confidence-inspiring steer the Mazda 6 is known for.

Popular questions about 2003 Mazda 6 steering bushes

Do all 2003 Mazda 6 models have steering rack bushes?
They do. The GG/GY Mazda 6 uses a hydraulic rack-and-pinion mounted to the front crossmember via rubber bushes. This is documented in the Mazda Workshop Manual’s Steering System section and reflected in Mazda EPC listings and aftermarket bush kits.

How long do steering bushes last on a 2003 Mazda 6?
Anywhere from 100,000 to 200,000 km is common, depending on road quality, heat, and fluid leaks. Cars that see lots of coarse-chip highways or have power-steering seepage usually wear bushes quicker. Regular inspections help catch them before they cause tyre wear.

Should they go with polyurethane or rubber bushes?
For a daily driver, rubber keeps it quiet and comfy. If they want sharper steering feel and don’t mind a bit more feedback, polyurethane is a good upgrade. Either way, using quality parts and following the Mazda torque specs is key, and an alignment afterwards is a must.
