Parts for your 2005 Mazda 6-Steering bushes

2005 Mazda 6 steering bushes — purpose, fitment, and when to replace

Based on technical sources, steering bushes are fitted to the 2005 Mazda 6 (GG/GY). The Mazda 6 (GG/GY) Workshop Manual (Steering — Rack-and-Pinion) specifies rubber “steering gear mounting insulators” that locate the rack on the front crossmember, and the Mazda Electronic Parts Catalogue lists these insulators/bushes as serviceable items. Aftermarket technical catalogues also offer replacement rack-mount bush kits for 2002–2008 Mazda 6 models, confirming real-world fitment.

On this Mazda 6, the steering bushes cradle the rack-and-pinion housing and keep it aligned while damping vibration. They’re essentially the cushion between the steering rack and the subframe, helping the wheel feel stay tight and direct without sending every bump through the column. Over time, rubber hardens, cracks, or swells from oil exposure, which can let the rack shift slightly under load. The driver notices it as vague on-centre feel, a light knock over sharp bumps, tramlining, or an annoying shudder when turning at low speed. Left alone, that extra movement can speed up wear on inner tie rods and tyres.

For servicing, a quick visual and lever check is worthwhile at each major service or around every 40–60,000 km. Look for cracked or oil-soaked bushes and any witness marks that show the rack has been moving. If engine oil or power steering fluid has been leaking onto the area, fix the leak and expect the bushes to degrade faster.

Replacement is typically straightforward: the rack can often stay in the car, the brackets are removed, bushes swapped, and everything torqued to factory spec. On higher-kilometre cars or in the presence of corrosion, slightly lowering the front subframe may help access. An alignment is recommended afterwards because any rack shift can alter toe. Many owners choose OE-style rubber for the best isolation, others go for quality polyurethane for a firmer, more connected feel at the expense of a touch more NVH. Parts pricing is modest and labour time is usually reasonable, making bushes a smart refresh on a 2005 Mazda 6 that’s starting to feel a bit loose at the wheel.

• Watch for: steering knock, vague feel, tramlining, uneven tyre wear
• Tips: keep oil leaks off the bushes, inspect related items (tie rods, sway bar and control arm bushes)
• After replacement: get a wheel alignment

Popular questions about 2005 Mazda 6 steering bushes

Do all 2005 Mazda 6 models have steering rack bushes?
Yes. The GG/GY-platform Mazda 6 uses rubber steering gear mounting insulators (bushes) to secure the rack to the front crossmember. They’re listed in the Mazda Workshop Manual and the OEM parts catalogue, and are widely available as replacement parts.

What are the signs my Mazda 6 steering bushes need replacing?
Common signs include a clunk over sharp bumps, vague or wandering steering on the motorway, and a shimmy when turning slowly or braking into a turn. Visible cracking or oil-soaked rubber around the rack mounts is another giveaway.

Can the bushes be replaced without removing the steering rack?
Usually, yes. On most 2005 Mazda 6s the rack can stay in place while the brackets are removed and the bushes swapped. Stubborn hardware or limited access may require slightly lowering the subframe. Always tighten to factory torque and book an alignment afterwards.
