Parts for your 2012 Holden Commodore-Rack boots

2012 Holden Commodore rack boots: what they do and when to replace them

Rack boots are definitely fitted to the 2012 Holden Commodore (VE Series II). Technical documentation backs this up: GM Holden Service Information for VE Series II (Steering – Rack and Pinion) illustrates bellows-style dust boots on each end of the steering rack, the GM/ACDelco electronic parts catalogue lists a “steering gear boot” for 2012 Commodore variants, and the Haynes Repair Manual for Holden Commodore 2006–2017 specifies inspection and replacement of rack boots on VE/VF models. So yes—this car uses rack boots and they matter.

On this Commodore’s rack-and-pinion setup, the boots (also called bellows) protect the inner tie rod joints and the rack bar from grit, water, and road grime. They help the inner joint retain grease and allow air to move as the rack travels, keeping the steering smooth and consistent. If a boot splits or its clamp loosens, contaminants can chew out the inner tie rod and the rack seals. On hydraulic racks, finding power steering fluid pooled in a boot is a tell-tale sign of an internal rack leak that needs attention.

As part of regular servicing, the rack boots should be visually checked every time the front end is inspected—think tyre rotations, brake checks, or any suspension work. Look for perished rubber, cracks at the concertina folds, oil weep inside the boot, or boots that have slipped off their grooves. Replacement is straightforward for a trained tech and is best paired with an alignment afterwards. It’s smart to inspect the inner tie rods at the same time, if there’s play, replace the joint and fit new boots and clamps together.

• Signs a rack boot needs attention:
  • Cracked, split, or oily boot
  • Clamps missing or loose, boot out of position
  • Grease flicked onto the inner wheel or chassis
• Service tips for a 2012 Commodore:
  • Use quality clamps rather than generic cable ties
  • Mark tie rod positions or count turns, then get a wheel alignment
  • If fluid is found in a boot, check the rack for internal seal leaks

Keeping those boots healthy is cheap insurance—protecting the rack, preserving steering feel, and helping the Commodore pass WOF/regos without drama.

Does a 2012 Holden Commodore have rack boots?

Yes. The VE Series II runs a rack-and-pinion steering gear that uses bellows-style rack boots on both ends. This is documented in GM Holden Service Information and supported by major parts catalogues listing “steering gear boot” for 2012 Commodore models.

How long do rack boots last, and when should they be replaced?

They can last many years, but heat, age, and road debris eventually crack or perish the rubber. Replace at the first sign of splitting, oil inside the boot, or if a clamp won’t hold. A quick check at every service is the best way to catch issues early.

Can they drive with a torn rack boot?

They could, but it’s not a good idea. A torn boot lets in grit and water that can rapidly wear the inner tie rod and rack seals, turning a small job into a big spend. It may also fail a WOF/regulatory inspection. Replace the boot promptly and get an alignment afterwards.
