Parts for your 2006 Toyota Aurion-Rack boots

2006 Toyota Aurion rack boots — what they do, why they matter, and when to replace them

Yes, the 2006 Toyota Aurion is fitted with rack boots. Technical references that list and depict these include Toyota’s Repair Manual for the GSV40 platform (Steering – Steering Linkage/Rack and Pinion sections), Toyota’s Electronic Parts Catalogue for Aurion GSV40R (showing “Boot, Steering Gear” at each end of the rack), and mainstream aftermarket catalogues used in Australia and New Zealand that supply Aurion-specific steering rack boots. So rack boots are absolutely relevant on this model.

On the Aurion, rack boots (also called steering rack bellows) sit on each end of the rack-and-pinion housing. Their job is simple but vital: keep dust, water, road grit, and sling-off at bay, protect the inner tie rods and rack seals, and hold a light smear of grease where it needs to stay. If a boot splits, contaminants can chew out the inner joint and the rack’s end seals, which can snowball into play in the steering and fluid leaks on hydraulic systems like the Aurion’s.

As part of routine servicing, a quick look under the bonnet and from beneath goes a long way. A technician should check both boots for cracks, oiliness from power steering fluid, or loose clamps. In Aussie and Kiwi conditions—UV exposure, heat, and coarse chip roads—boots can age faster, so it’s worth keeping an eye on them around 80–100,000 km or if the car sees gravel or coastal driving.

• Tell-tale signs a boot needs attention: visible splits, accordion folds perishing, wetness from fluid, or grit inside when squeezed lightly.
• If replacing: do both sides if one is gone, use quality clamps (not generic cable ties), and renew the inner tie rod dust grease to spec.
• Any time a tie rod end is disturbed, plan for a wheel alignment to keep tyre wear even and steering true.

Replacement is straightforward for a trained tech: lift safely, mark toe, pop the outer tie rod, slide off the old boot, clean, regrease lightly as specified, fit the new boot squarely, clamp it, then reassemble and align. Leaving a torn boot risks moisture corroding the rack and accelerating inner tie rod wear—far pricier than a simple boot service.

Popular questions about 2006 Toyota Aurion rack boots

Do all 2006 Toyota Aurions have rack boots?

They do. The Aurion runs a hydraulic rack-and-pinion setup, and each end of the rack is protected by a rubber bellows-style boot. Toyota’s service information and parts listings both show these boots as standard fitment on GSV40R Aurion.

If yours looks different at a glance, it’s usually just the angle of the splash shield or subframe—peek past the tie rod end and you’ll see the accordion boot on the rack housing.

How often should the rack boots be replaced?

There’s no fixed kilometre interval, they’re replaced on condition. At each service, check for cracks, splits, loose clamps, or signs of fluid. In hot, sunny climates or on cars that live on gravel, expect ageing sooner and consider pre-emptive replacement when they start to harden.

Any damage or oiliness means it’s time—don’t wait, as contamination can take out the inner tie rods and rack seals.

What happens if a rack boot splits and it’s not fixed?

Dirt and water can get in, drying out the inner joint and wearing the rack end seal. That can lead to knocking, vague steering, uneven tyre wear, and eventually power steering leaks that are far costlier than new boots.

Catch it early and the repair is usually just boots and an alignment, leave it, and you could be looking at inner tie rod or rack overhaul costs.
