Parts for your 2012 Isuzu D-max-Centre bearing

2012 Isuzu D‑Max centre-bearing

Based on technical sources, a centre-bearing is relevant to the 2012 Isuzu D‑Max on most variants. The Isuzu D‑Max 2012 Workshop Manual (Driveline/Propeller Shaft section) details a two‑piece propeller shaft with a centre support bearing on common 4x4, Crew Cab, and longer wheelbase models. The Isuzu Electronic Parts Catalogue (Propeller Shaft group) also lists a “Center Bearing Assy” for 2012‑on D‑Max applications, which aligns with the shared driveline architecture documented in the 2012 Holden Colorado RG workshop literature.

There are exceptions: certain 4x2 Single Cab short wheelbase models may run a one‑piece tailshaft, which doesn’t require a centre-bearing because the shorter span doesn’t need mid‑shaft support. For the majority of 2012 D‑Max utes on Aussie and Kiwi roads—especially dual cabs and 4x4s—a centre-bearing is fitted and serviceable.

On a 2012 Isuzu D‑Max that’s equipped with one, the centre-bearing’s job is simple but crucial: it supports the two‑piece tailshaft between the gearbox and the diff, keeping the shaft aligned under load, reducing vibration, and allowing smooth power delivery. The rubber mount in the carrier isolates driveline buzz so the cab stays calm, and the bearing itself lets the shaft spin true at highway speeds.

As the kays rack up—or if the ute’s been working hard off‑road, towing, or lifted—the rubber can perish and the bearing can wear. Classic tells include a shudder on take‑off, a droning or rumbling that changes with speed, a “thunk” on gear changes, and visible sag or cracking in the carrier mount. If any of that shows up, it’s time for an inspection.

Replacement is straightforward for a trained tech. The tailshaft is marked for orientation, removed in halves, and the old bearing is pressed off the front shaft. The new bearing and carrier go on in the right direction (there is a front and rear), then everything’s reassembled to factory alignment and torque settings. It’s smart to check uni joints, slip yoke play, and centre the carrier to keep the shaft running true. On lifted or lowered D‑Maxes, driveline angles should be verified—spacers or shims may be required to avoid premature wear.

There’s no fixed kilometre interval for replacement, but an underbody check at each service is cheap insurance. Keep an eye on the carrier rubber and listen for new vibrations after tyre, suspension, or diff work. If the ute’s had a knock to the tailshaft or you’ve replaced the bearing, a balance check is worth it to keep it silky on the open road.

• Typical service tip: inspect carrier rubber and mounting bolts every 10,000–15,000 km.
• When replacing: use quality components, match the bearing size to VIN, and follow workshop torque specs.
• After install: road test across speeds and loads, and recheck fasteners.

Popular questions about 2012 Isuzu D‑Max centre-bearing

Does a 2012 Isuzu D‑Max have a centre-bearing?
Most do. Dual cab and 4x4 variants commonly run a two‑piece tailshaft with a centre support bearing. Some short‑wheelbase 4x2 single cabs use a one‑piece tailshaft and won’t have one. A quick under‑vehicle look will show the carrier bracket near the middle of the shaft if it’s fitted.

What are the symptoms of a failing centre-bearing on a D‑Max?
Look for take‑off shudder, a speed‑related rumble, clunks on throttle changes, and a drooping or cracked rubber carrier. These symptoms can overlap with worn uni joints or diff issues, so a proper inspection is the way to nail it.

Do I need a tailshaft balance after replacing the centre-bearing?
If the shaft was reassembled in its original orientation and the bearing seated correctly, often no. But if there’s any new vibration, or the shaft’s seen damage, a balance check is a sensible step to protect the gearbox, diffs, and mounts.
