Parts for your 2015 Holden Colorado-Centre bearing

2015 Holden Colorado centre-bearing — used on most variants

Based on technical references, a centre-bearing is relevant and used on the 2015 Holden Colorado (RG). The Holden RG Colorado Workshop Manual (2012–2016, Driveline/Propeller Shaft section) specifies a two-piece tailshaft with a centre support bearing for most crew cab and space cab models. GM’s Electronic Parts Catalogue for MY15 Colorado lists a centre support bearing within the propeller shaft assembly on these variants. This aligns with platform-sharing service information for the Isuzu D‑MAX (same generation), and the prevalence of centre-bearing listings for 2012–2016 Colorado in major aftermarket catalogues from driveline suppliers. Some short-wheelbase single-cab 4x2 models may use a one-piece shaft without a centre-bearing, but for the bulk of 2015 Colorados on Aussie and NZ roads, the centre-bearing is part of the driveline.

The centre-bearing on a 2015 Holden Colorado supports the two-piece tailshaft, keeping everything aligned under load so the ute stays smooth on take-off and at highway speeds. It sits mid-way along the shaft in a rubber isolator, controlling vibration and helping the universal joints and diff live a longer, happier life. When it’s healthy, it’s invisible, when it’s tired, drivers notice shudder under acceleration, a droning or humming around 40–70 km/h, and sometimes a clunk on throttle changes.

Servicing-wise, it’s smart to have the centre-bearing inspected during routine maintenance or any time the tailshaft is out—especially if the vehicle tows, carries big loads, or sees corrugations and creek crossings. Look for perished or torn rubber, excessive play, or roughness/noise when spinning the bearing by hand. If replacement’s needed, marking the shaft halves for phasing before disassembly is critical to avoid new vibrations. Many owners choose to renew nearby wear items (like uni joints and the gearbox mount) at the same time, and a driveline shop can press the bearing and re-balance the shaft if required.

Fitment care matters: seat the bearing squarely in the bracket, don’t preload the rubber, and tighten fasteners to the workshop manual torque specs. On refit, check pinion angle and centre-bearing height/shimming where applicable. Quality parts—genuine or reputable aftermarket—pay off in longevity. After the job, a quick road test across a range of speeds will confirm the shudder’s gone and the ute’s back to being the comfy workhorse it should be.

• Does every 2015 Holden Colorado have a centre-bearing?
  Most crew cab and space cab 2015 Colorados use a two-piece tailshaft with a centre-bearing. Some short-wheelbase single-cab 4x2s may run a one-piece shaft and won’t have one. A quick look under the ute or a VIN-based parts check will confirm the setup.
• What are common symptoms of a worn centre-bearing?
  Shudder on take-off, a mid-speed vibration or droning (often 40–70 km/h), and a clunk when coming on/off throttle are typical. Visual checks often show cracked or separated rubber around the bearing support.
• How much does replacement usually cost?
  In Australia and New Zealand, expect parts and labour to land roughly in the mid-hundreds, varying with brand choice, whether uni joints are done at the same time, and if the shaft needs re-balancing. A driveline specialist can provide a firm quote once they’ve inspected the tailshaft.
