Parts for your 2009 Mazda Bt-50-Steering bushes

2009 Mazda BT-50 steering bushes

Steering bushes are fitted to the 2009 Mazda BT-50 (UN series). Technical references that confirm this include the Mazda BT-50 (UN, 2006–2011) Workshop Manual – Steering/Power Steering Gear section, which details the rack-and-pinion steering gear secured to the crossmember with rubber mounting bushes, the Ford Ranger PJ/PK Workshop Manual (the BT-50’s platform twin) describing the same layout, and major aftermarket catalogues (e.g., SuperPro and Nolathane) that list steering rack mount bush kits specifically for 11/2006–2011 BT-50 models.

The BT-50’s steering bushes sit between the steering rack and the front crossmember, keeping the rack firmly located while soaking up vibration and harshness. In everyday terms, they help the ute steer straight and feel tight at the wheel without transmitting every bump through the cabin. Over time, rubber can crack, squash, or get oil-soaked, which lets the rack shift slightly under load. That’s when the steering can start to feel vague, clunky, or wander on coarse roads.

Common signs they’re due include:

• Clunks or knocks when turning or over sharp bumps
• Steering shimmy or a loose, floaty feel on-centre
• Uneven or accelerated front tyre wear
• Visible cracks, separation, or oil swelling in the bushes

During servicing, a quick inspection pays off: with the front safely supported, have a helper gently turn the wheel lock-to-lock while watching the rack. Excess movement at the mounts points to tired bushes. Also note any power steering fluid leaks, oil contamination accelerates rubber deterioration.

Replacement is straightforward for an experienced DIYer or workshop: support the rack, remove the mount bolts, swap bushes, and torque everything to spec at normal ride height. A wheel alignment is recommended afterwards, as even small shifts can nudge toe settings. For bush material, OE-style rubber keeps NVH low and ride refined, while quality polyurethane options sharpen steering response and generally last longer off-road or with heavy loads, at the expense of a touch more vibration.

There’s no fixed interval—condition and use are the deciders. Utes that tow, carry weight, or see corrugations often need bushes earlier (say 120,000–180,000 km), while gentler use can stretch them well past 200,000 km. When replacing, it’s smart to check inner/outer tie rods, lower control arm bushes, and the steering shaft coupling at the same time so the front end stays tight and predictable.

Popular questions about 2009 Mazda BT-50 steering bushes

How can someone tell if the steering bushes are worn on a 2009 BT-50?
Look for clunks over bumps, a vague or wandering feel, and shimmy at the wheel. A visual check can reveal cracked or oil-swollen rubber. With the front raised, have a helper turn the wheel and watch for the rack shifting at its mounts—any notable movement suggests the bushes are tired.

Rubber or polyurethane bushes—what suits a BT-50 best?
Rubber keeps things quiet and comfy, great for daily driving. Polyurethane tightens steering feel and tends to last longer under towing or off-road use, but can pass a bit more vibration. For a touring or work ute that sees rough roads, many owners lean toward poly for durability.

Is a wheel alignment needed after replacing steering rack bushes?
It’s a smart move. Even if the rack goes back square, tiny changes at the mounts can tweak toe settings. A post-job alignment keeps tyre wear in check and ensures the steering tracks straight.
