Parts for your 2007 Toyota Aurion-Suspension bushes

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

Suspension bushes are absolutely fitted to the 2007 Toyota Aurion (GSV40 series). Technical references including the Toyota Aurion 2007 GSV40/GSV45 Repair Manual (Suspension section), Toyota’s Electronic Parts Catalogue, and local aftermarket catalogues from Nolathane and SuperPro list front lower control arm bushes, sway bar D-bushes and link bushes, plus rear trailing and lateral arm bushes for this model. That confirms the Aurion uses a range of rubber bushes across both axles.

On this Aurion, the bushes sit where arms and bars bolt to the body and subframes, letting the suspension move smoothly while soaking up road chatter. They keep alignment steady under braking and cornering, cut vibration in the cabin, and help the tyres maintain a clean contact patch. Front is a MacPherson strut layout with control arm bushes doing the heavy lifting for compliance and geometry, the independent rear uses multiple arms with bushes that manage toe and camber as the car loads up.

With age and kilometres, rubber can crack, harden or separate from its sleeve. Tell-tale signs on an Aurion include clunks on bumps, steering wander, shimmy under braking, or uneven tyre wear. In Australian and New Zealand conditions, many original bushes last 120,000–200,000 km, though heat, oil contamination or rough roads can shorten that.

• Inspection is smart at each service or at least every 20,000 km.
• Check after curb strikes, pothole hits or if a WOF/RWC flags movement.
• Look for torn rubber, off-centre sleeves, or wet, swollen rubber from fluid leaks.

When replacing, owners can choose genuine-style rubber for factory comfort or polyurethane for a sharper feel. Rubber keeps NVH low and suits daily use, quality poly can tighten steering response but may transmit a bit more road feel. Either way, it’s best practice to replace bushes in axle pairs and book a wheel alignment straight after.

• Torque bush bolts at normal ride height so they’re not pre-loaded.
• Consider complete control arms if the ball joints are tired — it can save press time.
• Keep oil and coolant off rubber, fix any leaks that could degrade new bushes.
• For sway bar D-bushes, match the bar diameter, use appropriate lubricant for polyurethane only.

Done right, fresh bushes restore the Aurion’s quiet, planted feel and protect tyres from premature wear — a tidy upgrade for comfort and confidence on Kiwi and Aussie roads.

Popular questions about 2007 Toyota Aurion suspension bushes

How long do the original bushes typically last on a 2007 Aurion?

Many factory bushes run 120,000–200,000 km, depending on climate, driving style and road quality. City kerbs, big potholes, and fluid leaks can shorten life, while gentle highway use tends to stretch it out. Inspection during regular servicing is the best guide.

Is a wheel alignment needed after bush replacement?

Yes. Changing control arm or rear arm bushes alters suspension geometry. A four-wheel alignment helps the Aurion track straight, keeps the steering wheel centred, and prevents uneven tyre wear after the work.

Should owners replace just the bushes or the whole control arm?

Pressing in quality bushes is cost-effective if the arms and ball joints are healthy. If ball joints are loose or the arm is worn, a complete arm can be better value and saves labour. Many shops quote both options so owners can pick what suits budget and condition.
