2006 Holden Commodore rack-boots: what they do and when to replace them

Technical sources including the Holden VE Commodore Workshop/Service Manual (Steering – Rack and Pinion), GMH Electronic Parts Catalogue, and mainstream parts catalogues for 2006 VE/VZ Commodore models all show bellows-style steering rack boots (also known as gaiters). So yes—rack-boots are fitted to the 2006 Holden Commodore and are a relevant service item.

On a 2006 Commodore, the rack-boots sit at each end of the steering rack, sealing the inner tie rods and keeping grit, water, and road grime out while holding grease in. Think of them as the rack’s dust masks—quietly doing the dirty work so the steering stays smooth and precise. When they’re healthy, the rack gears, bushes, and inner tie rods last longer, steering feel stays tidy, and there’s less chance of premature wear.

They’re made from flexible rubber or thermoplastic and cop plenty of heat and movement, so they eventually crack or split. Once torn, they can let in water and silt, which chews out the inner tie rod and can accelerate wear of the rack’s internal seals. On hydraulic cars, a split boot can also hide an internal leak by filling up with fluid—messy and not ideal for bushings.

As part of regular servicing, it’s smart to eyeball both boots every 10,000–15,000 km or at each oil service. Look for splits, perishing, oil inside the boot, or loose clamps. If any damage is found, replace the pair, not just one side—cheap insurance for even wear and consistent protection.

• Signs it’s time: visible cracks or tears, wet/oily boots, crunching grit sounds on steering, uneven front tyre wear, or vague steering feel.
• Replacement tips: measure and mark the tie-rod end position before removal, fit new clamps (don’t reuse tired ones), and book a wheel alignment afterwards—toe will almost always shift.
• While you’re there: check inner and outer tie rods for play and the rack for fluid seepage, it’s easier to fix related issues in one hit.

Quality boots last years, but road debris, heat, and age will get them eventually. Keeping them intact helps the Commodore steer straight, feel tight, and avoid bigger bills down the track—very Aussie, very sensible.

Popular questions about 2006 Holden Commodore rack-boots

How do you know if the rack-boots on a 2006 Holden Commodore need replacing?
They usually show visible splits or perishing, or feel oily from trapped power-steering fluid. You might also notice grit noises when turning, a slight knock over bumps, or accelerating tyre wear. A quick torch check with the wheels at full lock both ways often tells the story.

Do you need a wheel alignment after replacing rack-boots?
Yes, it’s recommended. Even if you carefully count threads or mark positions, removing tie-rod ends tends to nudge toe settings. An alignment after fitting new boots protects your tyres and brings the steering back on point.

Can a split rack-boot cause a power steering leak?
A boot itself doesn’t leak fluid, but a split can mask or worsen an internal rack seal leak, letting fluid pool inside the boot. If the boot’s wet with fluid, fix the underlying leak and replace the boot so dirt can’t attack fresh seals.
