Parts for your 2013 Isuzu D-max-Centre bearing

2013 Isuzu D‑Max centre-bearing: does it have one and what to do with it?

Based on the Isuzu D‑Max RT series workshop manual (Propeller Shaft section), the Isuzu Electronic Parts Catalogue for RT50 (2012–2016), and Australian/NZ driveline catalogues from Hardy Spicer and major parts retailers, the 2013 D‑Max is fitted with a centre-bearing (centre support bearing) on most dual cab and 4x4 variants that run a two‑piece tailshaft. Some short‑wheelbase 4x2 models may use a single‑piece tailshaft without a centre-bearing, but for the bulk of Aussie and Kiwi 2013 D‑Max utes, a centre-bearing is standard kit.

On vehicles where it’s fitted, the centre-bearing’s job is to support the two‑piece tailshaft in the middle, keeping driveline angles in check and cutting down on vibration. It takes load off the universal joints, helps the shaft run true, and makes the ute feel smoother under acceleration and at highway speeds. When the rubber isolator or bearing wears, you’ll often cop a shudder on take‑off, a droning or humming around 40–80 km/h, or a clunk as the load comes on and off.

As part of regular servicing on a 2013 D‑Max, a quick once‑over of the centre-bearing is a smart move:

• Inspect the rubber carrier for cracks, sagging or separation.
• Spin the shaft by hand (wheels safely off the ground) and listen/feel for roughness.
• Check for excessive play at the bearing and inspect nearby uni joints for wear.
• Look for misalignment or damaged brackets after off‑road use or heavy towing.

If replacement’s on the cards, the tailshaft will need to come out. Mark the shaft orientation before removal to keep the phasing spot‑on, and torque the mounts to spec on refit. It pays to check the uni joints and slip yoke at the same time, pairing a fresh centre-bearing with flogged uni joints won’t fix a vibe. Aftermarket and OE‑equivalent bearings are widely available for RT‑series D‑Max utes in Australia and New Zealand, with options in different bore sizes to match your shaft.

There’s no fixed change interval — it’s a condition‑based item. Vehicles that tow, carry loads, or see corrugations will typically need a centre-bearing earlier than city runners. Catching it early saves your uni joints and keeps that D‑Max running smooth and quiet.

Popular questions

What are the signs of a failing centre-bearing on a 2013 D‑Max?
Common giveaways are shudder on take‑off, a droning or humming between about 40–80 km/h, and a clunk as you get on and off the throttle. Visual checks often show a cracked or sagging rubber carrier.

How long does a D‑Max centre-bearing last?
There’s no set lifespan. Many last well past 150,000 km, but heavy towing, lifted suspensions, and rough roads can shorten it. Inspect it at each service and replace on condition.

Is it safe to drive with a worn centre-bearing?
Short term, you might get by, but it can get worse quickly and damage uni joints or the tailshaft. If there’s noticeable vibration or noise, it’s best to sort it promptly.
