Parts for your 2007 Holden Captiva 5-Rack boots

2007 Holden Captiva 5 rack boots — what they do and when to replace them

Yes, the 2007 Holden Captiva 5 runs rack boots. Technical references including the Holden Captiva CG (2006–2011) Workshop Manual – Steering, and GM Global Service Information for the Captiva/Winstorm platform describe a hydraulic power-assisted rack-and-pinion steering gear fitted with bellows-style rack boots (also called steering rack gaiters or steering gear boots) at each end of the rack.

On this Captiva 5, the rack boots are the flexible rubber bellows that seal the inner tie rods and the ends of the steering rack. Their job is simple but crucial: keep water, grit and road grime out, and keep the lubricating grease in. That protection stops premature wear of the inner tie-rod joints and the rack’s end bushings. If a boot splits, abrasive muck gets in and the steering can develop play, noise, or stiffness, and power steering fluid can pool inside the boot if there’s an internal rack seal leak.

As part of routine servicing, it’s smart to inspect both boots at every oil change or at least every 10,000–15,000 kilometres. Look for cracks, perishing, loose or missing clamps, or dampness from power steering fluid. A boot full of fluid usually points to a leaking rack seal, which is a separate repair.

Replacement is straightforward for a trained tech. The outer tie-rod end is removed, the old boot and clamps come off, the rack end is checked and cleaned, then a new boot is slid on and clamped with the correct ear or band clamps (not cable ties). Refit the tie-rod end to the marked position to preserve toe, then have the wheel alignment checked — minor adjustment is common. Always use quality boots that match the Captiva’s rack diameter so they seal properly under the bonnet heat and Aussie/Kiwi road conditions.

Typical signs it’s time for new rack boots include:

• Visible splits, perishing, or grease weeping from the bellows
• Clicking or looseness felt through the steering on rough roads
• Fluid inside the boot (suggesting a rack seal issue)
• Uneven tyre wear from toe shifting after boot damage

Tidy owners get ahead of it: replace aged boots before the inner tie rods and rack ends cop wear. It’s a low-cost part that protects a far pricier steering rack on the 2007 Holden Captiva 5.

Popular questions about 2007 Holden Captiva 5 rack boots

Do all 2007 Captiva 5 models have rack boots?
Yes. All CG-series Captiva 5 variants use a rack-and-pinion steering gear with bellows-style rack boots. The component is common across petrol and diesel trims of the era as noted in Holden/GM service literature.

How often should rack boots be replaced?
They’re not a fixed-interval item. Inspect every service, replace at the first sign of cracking, tearing, loose clamps, or contamination. Many last years, but climate and road grit can age them quicker. After replacement, get the wheel alignment checked.

Can a torn rack boot cause a WOF/roadworthy fail?
Often, yes. A split boot lets contaminants in and can indicate steering wear. In NZ and Australia, a visibly damaged or unsecured steering boot can lead to a fail until it’s repaired and the steering checks out.
