Parts for your 2012 Holden Colorado-Centre bearing

2012 Holden Colorado centre-bearing

Based on technical references including the Holden RG Colorado Service Manual (Driveline/Propeller Shaft, 2012), GM Global Electronic Parts Catalogue entries for “Bearing, Propeller Shaft Centre Support,” the platform-sharing 2012 Isuzu D‑Max workshop manual, and aftermarket catalogues from Hardy Spicer, SKF and GMB, a centre-bearing is fitted to 2012 Holden Colorado models that use a two-piece tailshaft (most 4x4 and many Crew Cab/High-Ride variants). Some 4x2 Single Cab, low-ride models run a one-piece tailshaft and therefore do not have a centre-bearing.

The centre-bearing on a 2012 Holden Colorado keeps the two-piece tailshaft steady, supporting it mid-span so the shaft runs true under load. With utes like the Colorado that have a longer wheelbase and sit higher, a two-piece tailshaft helps manage driveline angles, and the centre-bearing is the bit that stops vibration and harshness sneaking into the cabin. When it’s healthy, gear changes feel cleaner, take-offs are smoother, and there’s less stress on uni joints and the gearbox output.

What gives the game away when it’s tired? Owners usually notice a shudder on take-off, a thump or clunk when shifting from reverse to drive, or a droning/whirring noise that gets worse with speed. A quick look underneath can reveal a perished or torn rubber mount around the bearing, or visible sag so the shaft no longer sits centred.

• Inspection: Add the centre-bearing to routine servicing, especially if the ute tows, carries loads, or sees corrugations and off-road work. A 20,000–30,000 km check is a good rhythm.
• Replacement: Mark the shaft and flanges before removal to maintain phasing. Replace the carrier/bearing as an assembly, and check uni joints and the slip yoke while the shaft’s out. If the vehicle’s been lifted or levelled, confirm driveline angles so the new bearing isn’t loaded up.
• Fitment tips: Use quality parts, torque fasteners to spec from the workshop manual, and have the tailshaft balanced if there’s any doubt. Inspect engine, gearbox and diff mounts at the same time—excess movement there will quickly kill a fresh centre-bearing.
• Aftercare: Avoid prolonged water/mud immersion, and rinse the area after beach work. Keep an ear out for returning noise or vibration over the next few drives.

Looked after, the centre-bearing quietly keeps the Colorado’s driveline smooth and dependable, whether it’s hauling a trailer around town or tackling a long gravel run across the back blocks.

Do all 2012 Colorados have a centre-bearing?

No. Most 4x4 and many Crew Cab/High-Ride variants use a two-piece tailshaft with a centre-bearing. Some 4x2 Single Cab low-ride models run a one-piece shaft and don’t have one.

What are the common signs of a failing centre-bearing?

Shudder on take-off, a clunk changing from reverse to drive, and a droning or humming that rises with speed. A torn or sagging rubber mount around the bearing is another giveaway.

Is it okay to keep driving with a worn centre-bearing?

It’ll often still move under its own steam, but it can accelerate wear in uni joints and mounts, and vibration can get nasty fast. Best to book it in before it strands the driver or damages other driveline bits.
