Parts for your 2020 Holden Colorado-Steering bushes

2020 Holden Colorado steering bushes

Based on technical references for the RG-series Colorado — including the Holden RG Colorado workshop manual Steering section, GM’s electronic parts catalog for the 2012–2020 platform, and common aftermarket catalogues that list rack-mount bush kits for RG Colorado — the 2020 Holden Colorado uses a rack-and-pinion steering gear mounted to the front crossmember with isolator (steering rack) bushes. Steering bushes are therefore relevant and fitted to this ute.

On the 2020 Holden Colorado, the steering bushes sit where the rack bolts to the chassis crossmember. Their job is to keep the rack precisely located while soaking up vibration and impact from potholes, corrugations, and off‑road work. By isolating noise and harshness, these bushes help the Colorado steer straight, feel planted, and keep tyre wear even. Factory bushes are typically rubber for comfort, some owners step up to polyurethane for a tighter feel and extra durability, accepting a touch more road feel through the wheel.

As part of regular servicing, steering bushes deserve a look whenever the front end is inspected — think every 40,000–60,000 km, or sooner if the vehicle tows, carries a bull bar/winch, or sees plenty of rough tracks. Age, heat, oil contamination, and repeated impacts can crack or soften the material, letting the rack shift under load and dulling steering response.

• Common signs they’re tired: a clunk over bumps, vague on‑centre feel, steering shimmy, or visible rack movement while someone turns the wheel at idle.
• Good practice: check tie rods and rack boots at the same time, and book a wheel alignment after any bush replacement.

Replacement is a straightforward workshop job: support the rack, remove the mounting hardware, swap the bushes, then torque everything to spec. Most technicians allow 1–2 hours, depending on equipment and any accessories fitted. If choosing polyurethane, use the supplied, bush‑safe grease during install, for rubber bushes, avoid petroleum‑based lubricants that can degrade the compound.

For drivers wanting a sharper steering feel on bitumen or when towing, quality polyurethane bushes can lift precision. For those prioritising cabin refinement over rough roads, fresh OEM‑style rubber keeps noise down and comfort high. Either way, healthy steering bushes keep the 2020 Colorado tracking true and confidence high when the road gets choppy.

1. Inspect steering bushes alongside front suspension checks.
2. Replace at the first signs of cracking, oil swelling, or rack movement.
3. Finish with a proper alignment to protect tyres and steering feel.

Popular questions about 2020 Holden Colorado steering bushes

Do 2020 Colorados have steering rack bushes, or is it all electronic?
Yes, the 2020 Colorado runs a rack‑and‑pinion setup mounted with isolator bushes. Even where electric assist is used on some vehicles, the rack still relies on bushes to locate it and control vibration. On the Colorado, these bushes are serviceable and commonly replaced as the kilometres add up.

How long do the steering bushes typically last?
Lifespan varies with use. Many daily‑driven Colorados see 80,000–150,000 km before noticeable wear, while vehicles that tow heavy, tackle corrugations, or see frequent off‑road use may need bushes earlier. Regular inspections help catch softness or cracking before steering feel goes off.

Are polyurethane bushes worth it on a Colorado?
For drivers chasing a firmer, more direct steering feel and longer service life, polyurethane is a popular upgrade. Expect slightly more road texture through the wheel compared with rubber. Fitting quality parts and following the correct lubrication during install keeps squeaks at bay and results consistent.
