2006 Toyota Aurion steering bushes: what they do and when to replace them

Technical sources confirm the 2006 Toyota Aurion (GSV40 series) uses steering bushes. The Toyota repair manual for the GSV40 steering system illustrates the rack-and-pinion mounted to the front subframe via rubber bushes, and Toyota’s electronic parts catalogue lists the rack mount bush sub-assemblies for this model. Reputable aftermarket catalogues (including Nolathane, SuperPro and Whiteline) also publish specific rack-and-pinion mount bush kits for 2006–2012 Aurion/Camry XV40 platforms, which corroborates factory fitment.

The Aurion runs a hydraulic rack-and-pinion, and the steering rack is clamped to the front subframe with a pair of bushes. These rubber (or upgraded polyurethane) bushes isolate vibration, keep the rack located under load and help the wheel alignment stay true. When they wear, the front end can feel vague, you might hear a knock on sharp bumps, and the car can wander a touch on the motorway. Because they sit low, oil contamination from a power-steering weep can soften the rubber and speed up wear.

For owners who like their Aurion tight and tidy, checking the steering bushes is a smart part of routine servicing. A quick visual at every service or 20,000 km is worthwhile: look for cracking, distortion, or rubber that’s shiny and swollen from oil. Rocking the steering left–right with the wheels on the ground while watching the rack mounts can reveal excessive movement. If there’s play, it’s time.

Replacement is straightforward for a competent tech: support the vehicle safely, mark rack positions, remove the rack clamp bolts, swap in new bushes (mind the orientation), and torque everything to spec. If the existing bushes are oil-soaked, fix any power-steering leaks first or the new parts won’t last. A wheel alignment afterwards is recommended, as any shift at the rack can nudge toe settings.

Choosing materials comes down to feel. Fresh OEM-style rubber retains factory refinement. Quality polyurethane firms up the steering on turn-in and resists oil and heat better, which plenty of Kiwi and Aussie owners prefer for long-term durability. Either way, doing the bushes before they’re totally flogged preserves tyres, reduces bump-steer and brings back that confident Aurion steering feel.

• Common symptoms of worn steering bushes:
  • Clunk or knock over potholes or driveway entries
  • Vague on-centre feel or tramlining
  • Uneven or accelerated front tyre wear

Popular questions

What are the signs my 2006 Aurion’s steering bushes need replacing?
Tell-tales include a dull knock across bumps, vague or wandering steering at highway speeds, and toe wear on the front tyres. With the wheels on the ground, have someone nudge the steering wheel while you watch the rack—if the rack shifts in its mounts, the bushes are likely tired.

How long do Aurion steering bushes typically last?
On an unmodified daily driver they can run well past 100,000 km, but heat, age and oil contamination shorten their life. City kerb hits and rough roads don’t help. If the car has a power-steering fluid leak, expect the rubber to soften early—sort the leak before fitting new bushes.

Rubber or polyurethane—what’s better for an everyday Aurion?
Fresh OEM-style rubber keeps factory comfort and NVH. Polyurethane sharpens response and shrugs off oil, which many owners like for durability. For a commuter that sees the odd spirited run, quality poly is a solid choice, for maximum comfort, stick with rubber.
