Parts for your 2003 Holden Commodore-Cv boots

2003 Holden Commodore CV boots

Technical references confirm CV boots are relevant to most 2003 Holden Commodore (VY series) models. The Holden VY Series Service Manual and GMH parts catalogue specify rear half-shafts with inner and outer constant velocity (CV) joints and rubber boots on IRS-equipped sedans. Ellery’s/ Gregory’s repair manuals and major parts catalogues also list rear CV boot kits for VY IRS cars. However, VY wagon and ute variants typically use a live rear axle and don’t have rear CV boots, and there are no front CV boots on any VY because it’s rear-wheel drive.

On a 2003 Holden Commodore sedan with independent rear suspension, CV boots are the flexible rubber bellows that seal grease around each rear CV joint and keep water and grit out. They’re small, but they do a massive job—without intact boots, the joint’s lubricant flings out, road grime gets in, and the CV joint wears quickly, leading to shudder or clicking under load and, eventually, a costly axle replacement.

As part of regular servicing, it’s smart to check the rear CV boots every service or 10,000–15,000 km. A quick look behind the rear wheels for splits, perished rubber, or grease sprayed around the inner guard or suspension arms is usually enough. If there’s any cracking, oil-softening, or grease weeping, sort it early. A fresh boot kit and the right moly CV grease will save the joint from premature failure.

If a boot has torn but the joint is still quiet and smooth, a boot-only replacement is often fine: remove the half-shaft, clean out the old grease, inspect the races and balls, repack with the specified CV grease, fit the correct-profile boot, and crimp the stainless clamps properly. Always follow the workshop manual for shaft removal and refit torque settings, and get a post-repair road test to check for vibration. If the joint is noisy, notchy, or has excessive play, go for a complete CV/shaft assembly instead of just a boot.

Driving long distances with a split boot isn’t a great idea—once the grease is gone and water’s in, damage can happen fast, especially after wet-weather or gravel-road use common across Australia and New Zealand. Keep the boots happy, and the Commodore’s rear end will stay smooth, quiet, and drama-free.

• Common signs of trouble: visible splits, grease fling, rear-end clicking on acceleration or tight turns, vibration on throttle.
• Helpful tip: inspect after tyre rotations or brake work while the car’s already in the air.

Popular questions about 2003 Holden Commodore CV boots

Do all 2003 Commodores have CV boots?
Most VY sedans do at the rear because they use independent rear suspension with CV half-shafts. VY wagons and utes usually have a live rear axle, so no rear CV boots. None of them have front CV boots because the Commodore is rear-wheel drive.

How often should the CV boots be replaced?
There’s no fixed replacement interval—boots are replaced on condition. Inspect at every service. Replace immediately if there’s cracking, grease leakage, or a torn clamp. In harsher conditions (gravel roads, coastal exposure), step up inspections as rubber ages faster.

Can it be driven with a torn CV boot?
Short trips to a workshop are usually okay, but continued driving risks washing out grease and grinding the joint with grit. If there’s noise or vibration, the CV joint may already be worn and a full shaft replacement could be the smarter fix.
