Parts for your 2013 Holden Colorado-Centre bearing

2013 Holden Colorado centre-bearing — what it does and how to look after it

Technical confirmation: A centre-bearing is used on most 2013 Holden Colorado (RG) models with a two-piece propeller shaft — that includes the bulk of Dual/Crew Cab 4x2 and 4x4 variants. This is supported by GM Holden Global Service Information driveline diagrams, the Holden/ACDelco electronic parts catalogue listing a “Propeller Shaft Centre Support Bearing” for RG VIN ranges, and major aftermarket fitment catalogues (e.g., Mackay Rubber and Kelpro) that specify centre-bearing kits for 2012–2016 Colorado. Note: some short-wheelbase 2WD single-cab variants run a single-piece tailshaft and won’t have a centre-bearing.

On a 2013 Holden Colorado that’s fitted with one, the centre-bearing (also called a carrier bearing) supports the middle of the two-piece tailshaft. It keeps the driveline running true, manages shaft angles between the gearbox and rear diff, and cuts vibration and noise under load. By stabilising the shaft, it helps protect the uni joints, output seal and diff pinion from copping extra stress, especially when towing or heading off-road.

It’s a sealed bearing with a rubber mount, so there’s no greasing to do, but it should be inspected during regular servicing. A quick look for perished rubber, sagging, cracking, or rust-coloured dust around the bearing goes a long way. If the Colorado’s developed a shudder on take-off, a droning or humming around 40–80 km/h, or a clunk on throttle changes, the centre-bearing is a usual suspect.

Replacement is straightforward for a driveline specialist and worth doing before it snowballs into uni-joint or gearbox output wear. When swapping the bearing, correct tailshaft alignment and balance are crucial. The shaft should be marked before disassembly so sections go back in the same orientation. It’s smart to check uni joints at the same time and verify driveline angles — suspension lifts, big tyres or constant heavy loads can push angles out and shorten bearing life.

How long do they last? Plenty see well over 100,000 kilometres, but harsh conditions, towing and corrugations can bring that forward. If the rubber support is torn or the bearing feels rough, replacement is the fix. Quality OEM-equivalent parts and proper torque on the carrier bracket help avoid repeat issues.

Tip for longevity: keep an eye on pinion and gearbox mount condition, and avoid driving long distances with a known vibration — it can quickly escalate into more expensive repairs.

• Common symptoms: take-off shudder, mid-speed drone, clunks on and off throttle, visible rubber cracking/sag.
• Best practice: inspect every service, especially after off-road trips or towing.
• Have angles/balance checked if the vehicle is lifted or has driveline mods.

FAQs

Does a 2013 Holden Colorado have a centre-bearing?
Most RG Colorados (2013) with a two-piece tailshaft do — that’s common on Dual/Crew Cab 4x2 and 4x4 models. A quick glance under the ute will show a carrier bracket roughly mid-way along the shaft. Some short-wheelbase 2WD single cabs may have a single-piece shaft and won’t use one.

What are the signs the centre-bearing needs replacing?
Shudder on take-off, a humming or droning between 40–80 km/h, clunks when shifting from drive to coast, or a visibly cracked/sagged rubber mount. If it’s noisy or the rubber is torn, it’s time to replace.

Is it safe to keep driving with a failing centre-bearing?
Short trips to the workshop are usually fine, but continuing to drive can accelerate wear in uni joints, the tailshaft and the gearbox output seal. If vibration is strong or noise is worsening, book it in promptly.
