Parts for your 2018 Holden Barina-Rack boots

2018 Holden Barina (TM) rack boots — what they do and when to replace them

Technical sources confirm the 2018 Holden Barina (TM series, T300 platform) uses a rack-and-pinion steering gear with rubber bellows-style rack boots on each end. GM Service Information for the T300 platform includes procedures for steering gear boot clamp/boot replacement and associated exploded diagrams, and the Holden/GM Electronic Parts Catalogue lists “Boot, Steering Gear” for the TM Barina. Major aftermarket catalogues in AU/NZ also list rack-and-pinion boot kits for 2011–2018 Barina models. So yes — rack boots are fitted and very relevant to this vehicle.

On the Barina, those ribbed rubber boots shield the steering rack and inner tie rods from grit, water and road spray. Even though the TM runs electric power steering (no hydraulic hoses at the rack), it still relies on tight, intact boots to keep the rack grease clean and the rack bar free from corrosion and pitting. If a boot splits, dust and moisture work their way in, shortening the life of the inner tie rods and the rack itself.

As part of routine servicing, it’s smart to have the boots inspected at each service or roughly every 10,000–15,000 kilometres. A quick look for cracking, splits at the concertina folds, loose or missing clamps, or grease staining goes a long way. Any play in the steering, a light knock over bumps, or uneven tyre wear can also hint at a boot or inner tie rod issue.

• Replace boots in pairs if one has failed — the other side is often not far behind.
• Use quality clamps (ear or band type) rather than cable ties to maintain a proper seal.
• Centre the steering before clamping so the boot doesn’t bind at full lock, and avoid twisting the boot on install.
• If the boot is found wet with oil, that points to an internal rack seal fault rather than the boot itself, and the rack may need further work.

Replacement on a Barina is straightforward for a trained tech: remove the outer tie rod end, slide off the old boot, clean the rack bar, then fit the new boot and clamps to spec, refitting the tie rod to the same position. A wheel alignment check is recommended afterwards — if the tie rod position shifts even slightly, toe can change. Sticking with OEM or reputable aftermarket boots made from high-grade elastomer will better handle Aussie and Kiwi heat, UV and road grime, keeping the steering light, precise and drama-free.

Popular questions

Does the 2018 Holden Barina actually have rack boots?
Yes. Factory documentation (GM Service Information for the T300 platform and the Holden/GM EPC) shows bellows-style boots at both ends of the steering rack. Aftermarket AU/NZ parts catalogues also carry specific boot kits for the TM Barina, confirming fitment.

How often should Barina rack boots be replaced?
They don’t have a fixed interval, they’re replaced on condition. Inspect every service. If any cracking, splits, loose clamps or contamination is found, replace immediately. Many last for years, but harsh heat, UV and steering lock use can age the rubber sooner.

Can universal boots be used on a Barina?
Universal boots can work in a pinch, but vehicle-specific boots generally fit better, keep proper travel at full lock and seal more reliably. For longevity and steering feel, most techs prefer OEM or quality brand direct-fit boots.
