Parts for your 2006 Toyota Aurion-Rack boots

2006 Toyota Aurion rack boots: what they do and when to replace them

Yes, rack boots are fitted to the 2006 Toyota Aurion. Technical references including the Toyota Aurion (GSV40) Repair Manual, Steering – Rack and Pinion section, and the Toyota Electronic Parts Catalogue for GSV40 list and illustrate the “steering gear boot” (bellows) on both sides of the rack. Industry parts catalogues for this model also specify direct-fit rack boots, confirming their use on the Aurion’s hydraulic rack-and-pinion steering.

On a 2006 Aurion, the rack boots are the concertina-style rubber bellows that seal each end of the steering rack where the inner tie-rods attach. Their job is simple but critical: keep grit, water and road grime out of the rack and protect the inner tie-rod joints and rack seals. When a boot cracks or tears, contaminants get in and grease gets out, which can quickly wear the inner joint and, on hydraulic systems, allow power steering fluid to pool inside the boot—often a sign of a leaking rack seal.

As part of routine servicing, it’s smart to inspect the rack boots every service interval (about every 10,000–15,000 km) or any time the front end is up for tyres, brakes or suspension work. Look for:

• Perished, split or oil-soaked rubber
• Loose or missing clamps
• Grease fling or wetness around the inner tie-rod area
• Knocks, stiffness or wandering that suggest inner joint wear

If a boot is damaged, replace it promptly—ideally both sides if the rubber is the same age. Use quality OE-equivalent EPDM boots and proper crimp or ear clamps rather than cable ties. The job typically involves removing the outer tie-rod end, sliding the old boot off, cleaning the rack neck, then installing the new boot and clamps. Count the turns when removing the outer tie-rod to keep toe close, but book a proper wheel alignment afterward to protect tyres.

If fluid is found inside a boot, that’s more than a torn bellows, it points to an internal rack seal leak. In that case, a rack overhaul or replacement is the long-term fix. Keeping the Aurion’s rack boots intact is cheap insurance for smooth, light steering and helps avoid costly rack repairs down the track.

What are the signs the 2006 Aurion’s rack boots need replacing?

Typical clues include visible cracks or splits in the bellows, wet or greasy buildup near the inner tie-rod, or loose/missing clamps. Steering that feels notchy, wanders, or develops clunks over bumps can indicate contamination has already worn the inner joint. Finding power steering fluid inside a boot is a red flag for a leaking rack seal.

How often should rack boots be checked on a 2006 Toyota Aurion?

Have them inspected at every regular service—about every 10,000–15,000 km in Aussie and Kiwi conditions—or whenever tyres, brakes or suspension are being done. Heat, age and road grit are tough on rubber, so early checks catch small splits before they turn into rack damage.

Is it safe to drive with a torn rack boot?

Short-term driving might be possible, but it’s risky. A torn boot lets dirt and water attack the inner tie-rod and rack, accelerating wear and potentially leading to play or binding. It can also cause a WOF/RWC fail. Replace the boot promptly and get an alignment to keep the Aurion tracking straight and the rack protected.
