Parts for your 2008 Holden Colorado-Centre bearing

2008 Holden Colorado centre-bearing: what’s fitted and what it’s for

Based on factory documentation and parts catalogues for the RC-series (2008–2012) Holden Colorado — including the Holden/Isuzu driveline sections of the service manual and GM Holden EPC entries for “carrier, propeller shaft support” — a centre-bearing is fitted to most 2008 Colorado utes with a two-piece tailshaft (commonly space cab and crew cab, 4x2 and 4x4). Aftermarket catalogues for driveshaft centre support bearings (e.g., 30×62×30 mm assemblies specified for RC Colorado/D‑MAX 2007–2012) confirm this fitment. Single-cab short wheelbase 4x2 models may run a one-piece tailshaft and therefore do not use a centre-bearing.

• Models with two-piece tailshaft (most space/crew cabs): centre-bearing fitted.
• Some short-wheelbase single-cab 4x2 with one-piece tailshaft: centre-bearing not used, as the shorter shaft doesn’t require mid-span support.

For vehicles fitted with a centre-bearing, it plays a key role in driveline smoothness and longevity. The bearing sits in a rubber-insulated carrier bolted to the chassis crossmember, supporting the front and rear sections of the two-piece tailshaft. By anchoring the shaft mid-span, it controls runout, keeps universal joint angles in check, and soaks up vibration before it reaches the cab. That means less shudder on take-off, reduced NVH on the highway, and happier U‑joints and diff over the long haul.

Tell-tale signs the centre-bearing is on the way out include a thump or shudder launching from the lights, a droney vibration under load at 40–80 km/h, a rubber carrier that’s cracked or sagging, and visible play at the bearing. Left too long, it can accelerate wear in U‑joints and even the gearbox output or diff pinion bearings.

Servicing advice for a 2008 Colorado’s centre-bearing is straightforward: it’s not a lube-and-go item, but it should be inspected at every service, especially if the ute tows, carries heavy loads, or runs a lift. Check the rubber isolator for splits and the bearing for roughness. If replacement’s due, mark the tailshaft orientation before disassembly to preserve balance, support the shaft safely, separate the halves at the spline, and press the old bearing off/on with proper drivers. Refit the carrier bracket loosely, align the bearing so the rubber sits neutral (no preload), then torque all fasteners to the workshop manual spec. While it’s apart, assess U‑joints and the slip-yoke seal, and verify driveline angles — suspension lifts or worn mounts can preload the bearing and invite early failure.

On short-wheelbase single-cab 4x2s without a centre-bearing, the one-piece shaft is sufficiently short and stiff to control vibration without mid-support, reducing parts count and maintenance while meeting NVH targets set out in the RC-series driveline design guidance.

Does a 2008 Colorado always have a centre-bearing?

Most space and crew cab RC Colorados do, as they use a two-piece tailshaft. Some short-wheelbase single-cab 4x2 variants use a one-piece tailshaft and won’t have a centre-bearing. A quick underbody look for a carrier bracket at mid-wheelbase will confirm which you’ve got.

How long should a centre-bearing last?

With normal use, many see 150,000–250,000 km. Heavy towing, lift kits, worn engine/gearbox mounts, or frequent off‑road corrugations can shorten that. Regular inspection of the rubber carrier and listening for take-off shudder helps catch issues early.

Is it safe to drive with a worn centre-bearing?

Short, gentle trips might be manageable, but it’s not recommended. Continued driving can hammer the U‑joints and other driveline components, turning a simple bearing swap into a bigger bill. If shudder or droning starts, plan a repair promptly.
