2019 Holden Colorado steering-bushes: what they do and when to replace them

Technical references confirm steering-bushes are fitted and relevant on the 2019 Holden Colorado (RG series). The Holden/GM RG Colorado Workshop Manual (Steering – rack-and-pinion) and GM Global EPC list the steering gear mounting insulators (bushes) that secure the rack to the front crossmember. Major aftermarket catalogues for the RG Colorado (2012–2020) also offer replacement rack-mount bush kits, reinforcing that the part is serviceable on these utes.

On the 2019 Colorado, the steering-bushes sit between the steering rack and the chassis. Their job is to locate the rack precisely while soaking up vibration and harshness. Good bushes keep the rack centred so steering input translates cleanly to the road wheels, helping on-centre feel, turn-in, and tyre wear. Off-road corrugations, towing, bigger tyres and regular gravel work can accelerate bush wear, so they’re a genuine consumable on many working Colorados.

For servicing, a sensible approach is to inspect the steering-bushes at each scheduled service or roughly every 20,000 kilometres, and after any hard off-road trip. Look for perished rubber, cracking, oil swelling (from power-steering fluid leaks), or visible rack movement when the steering is rocked. Common tell-tales of worn bushes include:

• Vague steering, tramlining or a delayed response off centre
• Clunks over potholes or when selecting drive/reverse
• Uneven inner/outer tyre wear despite correct pressures

Replacement is straightforward for a trained tech: support the rack, remove the through-bolts, swap the bushes, then torque the hardware to spec. An alignment is recommended afterwards, as even small position changes can nudge toe. Owners can choose OE-style rubber for factory NVH, or quality polyurethane for crisper rack location on vehicles that see heavy towing, bull bars or rough tracks. If a bush has flogged out badly, also check the crossmember bores and the rack mounts for elongation or damage.

Simple longevity tips include keeping an eye out for power-steering leaks (fluid degrades rubber), avoiding blasting the bushes directly with a pressure washer, and checking them sooner if the ute runs larger tyres or spends time on corrugations. Look after the steering-bushes and the Colorado rewards with steadier tracking, quieter NVH and more predictable steering feel on bitumen and backroads alike.

Popular questions about 2019 Holden Colorado steering-bushes

Are steering-bushes the same as control arm bushes on a 2019 Colorado?
Not the same. Control arm bushes locate the suspension arms, while steering-bushes mount the steering rack to the chassis. Both affect handling and tyre wear, but steering-bushes mainly influence steering precision and rack stability.

How long do Colorado steering rack bushes typically last?
Many last 80,000–150,000 kilometres, but lifespan varies with use. Heavy loads, corrugations, larger tyres and fluid leaks can shorten their life. Regular checks catch wear before it affects alignment or causes clunks.

Can worn steering-bushes cause a WOF or RWC issue?
Yes. Excessive rack movement or perished bushes can be flagged during a WOF (NZ) or RWC (AU) inspection due to steering play or instability. Replacing the bushes and verifying alignment usually resolves it.
