Parts for your 2017 Holden Colorado-Rack boots

2017 Holden Colorado rack-boots

Rack-boots are absolutely used on the 2017 Holden Colorado. Technical references including the Holden RG Colorado workshop manual (MY17, Steering – Rack and Pinion) depict a rack-and-pinion steering gear with bellows-style boots on both ends of the rack. The GM/ACDelco electronic parts catalogue for MY17 Colorado likewise lists “Boot, Steering Gear” left and right, and mainstream parts catalogues for the RG Colorado (2012–2020) offer replacement rack-boot kits specifically for this model. That confirms the component is relevant and fitted to the vehicle.

On a working ute like a 2017 Colorado, rack-boots do a deceptively big job. They’re the flexible bellows that seal and protect the inner tie rod and the ends of the steering rack from dust, water, mud and road grit. By keeping contaminants out, they help the inner joint and rack seals last, maintain steering feel, and prevent costly wear. On-road touring, farm tracks or beach work—all of it throws grime at the front end, so healthy boots are cheap insurance.

As part of regular servicing, rack-boots deserve a quick look. A technician will scan for splits, perishing, loose or missing clamps, and any weeping of grease or fluid that suggests damage or a leaking rack. If a boot is torn, it should be replaced promptly, driving with a split boot invites grit into the inner joint and can turn a simple boot swap into a steering rack or inner tie rod replacement. Replacement is straightforward but precise: set the steering straight-ahead, mark toe, remove the outer tie rod end, swap the boot, fit correct clamps, reconnect any rack vent tube, then carry out a wheel alignment. Use quality boots that flex freely through the Colorado’s suspension travel.

• Check at each service (or every 10,000–15,000 km) for cracks, splits and clamp condition.
• If torn: replace the boot and inspect the inner tie rod and rack seals for play or contamination.
• Avoid packing the boot with grease—it’s a dust shield, not a grease reservoir. Only a light smear where specified by the manual.
• After any boot or tie rod work, get a proper alignment to protect tyres and restore steering feel.

Look after the rack-boots and the Colorado’s steering stays tight, precise and ready for whatever Aussie or Kiwi roads throw at it.

How often should rack-boots be inspected on a 2017 Holden Colorado?

They’re best checked at every routine service (about 10,000–15,000 km) or sooner if the vehicle sees off-road, beach or rural use. Any oil, grease or dirt build-up around the boot is a cue for a closer look.

What are the signs a rack-boot has failed?

Visible splits or perishing, missing or loose clamps, grease flung onto the control arms, or new play/noise in the steering over bumps. If water or grit has entered, the inner tie rod may feel loose.

Can the Colorado be driven with a torn rack-boot?

It can move, but it’s not a good idea. Contamination can quickly wear the inner joint and rack seals. Replacing the boot promptly is far cheaper than replacing a steering rack.
