Parts for your 2007 Toyota Aurion-Steering bushes

2007 Toyota Aurion steering bushes — what they do and when to replace them

Yes, the 2007 Toyota Aurion (GSV40) uses steering bushes. The steering rack is mounted to the front subframe with rubber rack-mount bushes (Toyota calls them “cushion, steering gear”). This arrangement is documented in the Toyota Aurion GSV40 Repair Manual (Steering System section) and shown in the Toyota Electronic Parts Catalogue. Aftermarket technical catalogues from suspension specialists also list steering rack mount bush kits for 2006–2011 Aurion models, confirming fitment.

On this Aurion, the steering bushes isolate the rack from vibration and road shock, keeping the rack located so the wheel alignment stays true while still filtering noise and harshness. When they age, harden or get oil-soaked, the rack can shift under load. That’s when owners start noticing vague steering, a knock on turn-in or over bumps, and sometimes feathered tyre wear.

As part of servicing, it’s smart to inspect the steering bushes every 20,000–30,000 km, or sooner if there’s a clunk from the front end. A quick check involves watching the rack while a helper rocks the steering wheel left-right with the engine idling, any rack movement relative to the subframe points to tired bushes. Look for cracking, deformation, or softened rubber from power steering fluid leaks.

Replacement is straightforward workshop work: support the rack, remove the mount bolts and brackets, swap the bushes, and torque the hardware to the factory spec from the Toyota manual. An alignment check afterwards is recommended, because improved rack location can slightly change toe. Owners can choose genuine-style rubber for OE comfort or quality polyurethane for a firmer, more direct steering feel. If there’s any seepage from the rack or lines, fix that first—new bushes won’t last if they’re constantly bathed in fluid.

On Aussie and Kiwi roads, many Aurions go 120,000–180,000 km before the original steering bushes get tired, but heavy city kerbing, rough rural surfaces, or big wheels can shorten that. If the front end feels floaty on lane changes, there’s a dull thud mid-corner, or the steering wheel needs constant correction, fresh bushes often restore the crisp, planted feel these cars are known for.

• Typical signs they’re due: clunk over bumps, wandering on the motorway, uneven front tyre wear, or visible rack movement.
• Best practice: inspect at regular service intervals, replace in pairs, and re-check alignment.

Popular questions about 2007 Toyota Aurion steering bushes

Do all 2007 Aurions have steering rack bushes?
Yes. The GSV40 Aurion uses rubber rack-mount bushes to secure the steering gear to the subframe. Toyota service information and parts catalogues identify these as steering gear cushions.

How long do the steering bushes typically last?
With normal driving they often last 120,000–180,000 km. Rough roads, fluid leaks, or frequent kerb impacts can shorten that. If the steering feels loose or knocks, have them checked regardless of kilometres.

Should they be upgraded to polyurethane?
Poly bushes sharpen steering feel and resist oil and heat better than rubber, which some drivers prefer. They can transmit a touch more vibration. For daily commuting, fresh OE-style rubber is great, for a sportier feel, quality polyurethane is a solid option.
