2004 Holden Commodore rack boots — purpose, care and replacement
Based on the GM Holden VY/VZ Service Manual (Steering — Rack and Pinion) and the Holden Electronic Parts Catalogue (EPC) listings for Group 6.800 “Boot, Steering Gear”, the 2004 Holden Commodore is equipped with rack-and-pinion steering that uses bellows-style rack boots on both sides of the steering rack. Aftermarket fitment guides from major Australian and New Zealand parts catalogues also list specific rack boot kits for 2004 Commodore variants, confirming the part is fitted and serviceable on this model year.
On the 2004 Commodore, rack boots (also called bellows or gaiters) protect the inner tie rods and the rack bar from road grime, water, and grit. They also help retain a light film of grease on the inner joint and allow the rack to move freely without contamination. For power-steered cars, if fluid is found inside a boot, it often points to a leaking rack seal rather than a boot issue alone.
As part of regular servicing, it’s smart to inspect the rack boots at each service interval. In Aussie and Kiwi conditions—heat, UV, and the odd gravel road—rubber can harden and crack. Catching a split early saves the steering gear from wear and keeps the car roadworthy.
- What to look for: cracks, splits, oil or ATF weeping from the boot, loose or missing clamps, and excessive play at the inner tie rods.
- When to replace: at the first sign of damage, don’t wait for grit to chew out the rack.
Replacement is straightforward for a trained tech. The tie rod end is removed, the old boot and clamps come off, and a new boot is slid on with proper clamps (not cable ties). The rack should be centred during fitment so the boot isn’t twisted at full lock. Once refitted, a wheel alignment is essential to protect tyres and restore steering feel. If fluid is present in a boot, have the rack assessed—boots won’t cure an internal seal leak.
Tips the workshop will follow on a 2004 Commodore:
- Use quality OE-style clamps to maintain a proper seal.
- Lightly grease the inner tie-rod ball and boot lip as specified, avoid petroleum products that attack rubber.
- After refitting, check for full, bind-free travel lock-to-lock and book an alignment.
- Use the correct power steering fluid (DEXRON III ATF is specified for this era) and check levels after any steering work.
Popular questions
Does a 2004 Holden Commodore have rack boots?
Yes. The GM Holden VY/VZ steering design is rack-and-pinion with bellows boots on both sides. Factory manuals and the Holden EPC list these boots as service parts for 2004 models, so they’re absolutely part of the car.
How often should rack boots be replaced?
There’s no fixed kilometre interval—replace on condition. Inspect at every service. In hot, sunny climates or with gravel use, boots can age faster. If there’s any cracking, splitting, or loose clamps, replace straight away and get a wheel alignment.
What are the signs a rack boot needs attention?
Visible cracks, grease or ATF inside or around the boot, clicking or play from the inner tie rod, and uneven steering feel are common flags. Finding power steering fluid inside a boot usually points to an internal rack seal leak that needs professional repair or replacement.
