Centre Bearing on the 2015 Isuzu D-Max: Is It Fitted and What You Should Know

The 2015 Isuzu D-Max is a rugged and reliable ute that has earned its stripes with Aussie drivers, whether on the worksite or out on the tracks. When looking under the vehicle, particularly at the driveline components, some might wonder if this model uses a centre bearing in its driveshaft assembly. After referencing technical manuals, workshop guides, and component breakdowns for the 2015 Isuzu D-Max, it turns out that a centre bearing is not actually part of the driveline setup on this particular model.

So why is there no centre bearing on the 2015 Isuzu D-Max? It largely comes down to its drivetrain design. The 2015 Isuzu D-Max uses a single-piece (one-piece) driveshaft rather than a two-piece or multi-section driveshaft that would require a centre bearing support. A centre bearing is typically needed when a driveshaft is split into multiple sections to manage length and reduce vibrations. Since the Isuzu D-Max uses a one-piece driveshaft, there is simply no need for a bearing mounted in the middle of the shaft to support it.

More specifically, a centre bearing's main role is to support a two-piece driveshaft and reduce driveline vibrations by providing an intermediate support point. Vehicles that have longer drivelines or use two-piece designs often require centre bearings to maintain shaft alignment and absorb the loads and oscillations that occur during operation. The 2015 D-Max's relatively short and straightforward one-piece driveshaft does not experience the same bending moments or length issues that would necessitate this extra support.

Because the 2015 Isuzu D-Max does not fit a centre bearing, this means there is one less component to inspect and replace during servicing. Drivers and mechanics can focus on maintaining other driveline components such as universal joints (U-joints), splines, and the differential, rather than worrying about the centre bearing condition.

That said, while a centre bearing may not be relevant to this vehicle, it's still important that the driveshaft and its related components remain in good shape. Regular inspections of the U-joints and driveshaft balance are essential to prevent vibrations and drivetrain wear. Faulty U-joints or imbalanced shafts can cause similar symptoms to what a worn centre bearing would produce on other vehicles, such as vibrations or noise from underneath the ute.

For those unfamiliar, if the 2015 Isuzu D-Max had a centre bearing, its role would be to support and locate a two-piece driveshaft and reduce vibrations caused by harmonic resonance and shaft imbalance. This is typically achieved through a rubber-mounted bearing bracket fixed to the chassis or crossmember. Under normal conditions, the centre bearing keeps the driveshaft aligned and assists in distributing loads evenly through the driveline.

Maintenance of a centre bearing involves checking the condition of the rubber mount, ensuring the bearing spins freely without excessive play or noise, and replacing the entire assembly if damage or wear is detected. Neglecting a worn centre bearing can result in driveline vibrations, noise, and in severe cases, damage to other driveline components or even driveshaft failure, potentially leading to dangerous situations on the road.

But in the case of the one-piece driveshaft found on the Isuzu D-Max 2015 model, that centre bearing maintenance task simply does not come into play. Drivers should instead put their attention on other driveline maintenance routines:

• Regular greasing of universal joints (if fitted with grease nipples)
• Checking for wear or looseness in U-joints
• Ensuring the driveshaft is free of dents, cracks or other damage
• Inspecting the driveshaft's balance and alignment during servicing
• Keeping an eye on differential and transfer case oil levels and seals

Compared to vehicles with two-piece driveshafts that include a centre bearing, the one-piece driveshaft arrangement on the 2015 Isuzu D-Max is simpler, which can translate to fewer parts requiring ongoing attention and a reduction in potential vibrations or misalignment issues. This design choice also has some cost benefits during repairs and maintenance, as there is one less component to source and fit if a bearing failure were ever a concern.

For D-Max owners keen to keep their trucks running smoothly, trust that the driveline design on the 2015 model means there is no centre bearing to worry about. Keep up with routine servicing and focus on the components that really matter for this vehicle, including driveshaft condition and universal joints. Following manufacturer schedules and addressing driveline issues early will help maintain smooth power delivery and avoid costly repairs down the track.
