Parts for your 2008 Mazda 6-Steering bushes

2008 Mazda 6 steering bushes — what they do and when to replace them

Yes, the 2008 Mazda 6 uses steering bushes. Technical documentation confirms it: the Mazda 6 (GH series) Workshop Manual, Steering (ST) section describes the rack-and-pinion steering gear mounted to the front subframe via rubber insulators/bushes and clamps, and Mazda’s Electronic Parts Catalogue (Group 32 Steering) lists the steering gear insulators as components of the rack assembly. Industry catalogues for replacement suspension and steering parts also list rack-mount bushes for the 2008 Mazda 6, even when Mazda supplies them as part of the complete steering gear.

On this model, the steering bushes sit between the steering rack and the front crossmember. Their job is to isolate vibration, keep the rack precisely located under load, and prevent that annoying knock over bumps. When they’re healthy, the car steers cleanly on centre and tracks straight, when they’re tired, the wheel can feel vague, the front end may thud or clunk, and small corrections become a constant thing on the motorway.

It’s fair to say these bushes live a hard life. Hydraulic power steering fluid leaks (common on higher‑kilometre cars) can soften rubber, and local roads, speed humps and kerbs all add to the punishment. As part of regular servicing, it’s smart to inspect the rack mounts for cracking, splits, or oil-soaked rubber. A quick check for rack movement while someone gently rocks the steering wheel can also reveal excess play.

Replacement is straightforward for a trained tech: the rack is supported, the clamps come off, old bushes are pressed out, new OEM rubber or polyurethane bushes go in, and everything is torqued to the factory spec from the workshop manual. A wheel alignment should follow, because even small shifts in rack position can nudge toe settings. Owners chasing a sharper steering feel may opt for polyurethane bushes, they’ll generally firm up response but can add a touch more road feel and noise, so daily drivers might prefer quality rubber.

Signs it’s time to book the job include:

• Knock or clunk through the column over bumps
• Wandering or tramlining at highway speeds
• Vague on‑centre feel or delayed response
• Visible cracks or oil-soaked rubber on the rack mounts

Look after the bushes by fixing any power steering leaks promptly and having them inspected at major services. It’s a small part that makes a big difference to how the 2008 Mazda 6 feels on Aussie and Kiwi roads.

Popular questions

How do you know the steering rack bushes are worn on a 2008 Mazda 6?
Typical giveaways are a dull clunk over sharp bumps, a vague or wandering feel on the motorway, and visible cracks or perishing in the rack mounts. A technician can also spot rack movement while the wheel is gently rocked side to side with the engine off.

Should you choose polyurethane or rubber bushes?
Poly bushes sharpen steering and resist oil, great for keen drivers. Rubber keeps factory comfort and isolation, which many daily drivers prefer. Either way, quality matters, and alignment afterwards is a must.

Do you need a wheel alignment after replacing steering bushes?
Yes. Even a slight change in rack position can alter toe. An alignment ensures the Mazda 6 tracks straight and the tyres wear evenly.
