Parts for your 2006 Toyota Aurion-Coil springs

2006 Toyota Aurion coil springs — what they do and when to replace them

Coil springs are absolutely relevant to the 2006 Toyota Aurion. Technical sources including the Toyota Aurion (GSV40/GSV45) Repair Manual (Chassis—Suspension) and Toyota Australia’s 2006 Aurion specification sheets describe a MacPherson strut front suspension and a dual‑link strut rear, both using coil springs. Independent aftermarket manuals for the XV40 platform (shared with Camry) echo the same setup.

On the Aurion, the coil springs carry the car’s weight, set ride height, and work with the struts/shocks to soak up bumps and keep the tyres planted. They also help maintain alignment angles during cornering and braking, which is why a tired spring can quietly cause uneven tyre wear and vague steering.

As part of regular servicing, it pays to eyeball the springs for cracked paint, rust pitting (especially on lower coils), and any signs of sagging. A quick ride‑height check and a bounce test can flag a weak or broken coil early. Coastal cars in Australia and New Zealand often show corrosion on the lower coil where road grime and salt collect.

If replacement’s on the cards, best practice is to swap springs in axle pairs (both fronts or both rears) to keep height and rate matched. Use quality OE‑equivalent or approved performance springs, and consider new upper mounts, insulators, and bump stops while the struts are out. Always perform a wheel alignment afterwards. Because springs are under serious tension, this job needs proper compressors and safety gear—leave it to a pro if unsure.

Those who tow or carry loads can look at heavy‑duty or progressive‑rate coils, but they should stay within legal ride‑height rules and maintain adequate shock travel. Matching fresh springs with good struts pays off in stability, braking confidence, and consistent tyre wear.

• Common signs the Aurion’s coil springs need attention:
  • Uneven stance or reduced ride height on one corner
  • Clunks, bottoming out, or a choppy ride
  • Uneven tyre wear despite correct pressures
  • Visible rust, cracked paint, or a fractured coil
• Service tip: inspect every 20,000–30,000 km, or sooner if driving on rough roads.

Look after the coil springs and the Aurion rewards with a quieter, safer, and more settled drive over the long haul.

Popular questions about 2006 Toyota Aurion coil springs

Do coil springs wear out, or should they last the life of the Aurion?

Many Aurion coil springs reach well over 150,000–250,000 km, but they can fatigue earlier with heavy loads, rough roads, or coastal corrosion. If ride height drops, the car leans to one side, or you hear knocks over bumps, they’re due for inspection and likely replacement in axle pairs.

Should coil springs be replaced when fitting new struts?

They don’t always have to be, but it’s smart to assess them at the same time. If the springs are rusty, sagging, or have chipped coatings, replace them along with mounts and insulators. New struts with tired springs can still leave the Aurion sitting low or riding harshly.

What ride height should a 2006 Aurion sit at?

Ride height is specified in the Toyota repair manual and is measured from defined chassis points. A practical check is measuring from wheel centre to guard lip and comparing left to right on the same axle. Noticeable variance or a stance that’s visibly low suggests spring fatigue or a broken coil.
