Centre Bearing on the 2014 Nissan Navara: Is It Needed and What You Should Know

The 2014 Nissan Navara is a popular choice among ute enthusiasts, especially in Australia where ruggedness and reliability are key. When diving into drivetrain components like the centre bearing, it's important to understand whether this particular part is relevant or even used on this model. Technical information and vehicle design details make it clear that the 2014 Navara does not utilise a centre bearing in its drivetrain setup. Here's why and what that means for maintenance and servicing.

A centre bearing, sometimes called a carrier bearing, is typically found on vehicles with a two-piece driveshaft. This bearing supports the intermediate shaft at the center of the vehicle, reducing vibration and helping to maintain alignment between sections of the driveshaft. Centre bearings are common on longer wheelbase vehicles or those with a split driveshaft arrangement, where one driveshaft connects the transmission or transfer case to the centre bearing, and another shaft runs from the centre bearing to the differential.

However, the 2014 Nissan Navara does not have a two-piece driveshaft system. Instead, it features a single-piece driveshaft that runs from the transfer case straight to the rear differential. Because there's only one shaft piece, there is no intermediate point that requires support. This design eliminates the need for a centre bearing altogether.

This design choice aligns with practicality and robustness, especially for a vehicle that is often used off-road or for work purposes. A single-piece driveshaft reduces the number of components that can wear out or fail, simplifying maintenance and improving durability. Without a centre bearing, there are fewer parts exposed to wear, noise, or vibration that might otherwise affect the vehicle's drivability or require regular inspection.

Since the 2014 Navara uses a single-piece driveshaft, maintenance tasks focus on other key parts such as the universal joints (U-joints), driveshaft balancing, and of course the regular checks on the differential and transfer case fluid levels. Universal joints are crucial because they allow the driveshaft to flex and move with the suspension while transferring power smoothly from the gearbox to the rear axle. If U-joints start to wear, they can produce noticeable clunks or vibrations much like a faulty centre bearing would on a vehicle that has one.

For Navara owners, servicing the driveshaft usually means periodic inspection of the U-joints for wear and lubrication if applicable (some are sealed for life). Any worn or damaged U-joint should be replaced promptly to avoid further driveline issues. It's also sensible to watch for any unusual vibrations, sounds, or changes in driving feel as these can hint at driveline problems that might masquerade as or be mistaken for centre bearing issues on other vehicles.

When it comes to sentiment around the centre bearing on vehicles that actually have them, it is important to understand why regular maintenance matters for that component. The centre bearing must handle the rotational forces and keep the driveline stable. Over time, the rubber or elastomer cushion within the centre bearing can degrade due to heat, age, dirt, and general wear. If the centre bearing wears out, the driveline can experience excessive vibration, noise, and even accelerated wear on adjacent components. Replacing a worn centre bearing restores smooth operation and extends the lifespan of the driveshaft system.

Even though the 2014 Nissan Navara does not require attention to a centre bearing, understanding its role can be helpful if a driver compares the Navara to larger or different vehicles with split driveshaft configurations. Vehicles like certain vans, large SUVs, or trucks with long wheelbases are more likely to have a two-piece driveshaft setup and therefore need centre bearing maintenance.

In short, the 2014 Nissan Navara is designed with a straightforward and durable drivetrain that excludes the centre bearing. This not only cuts down on parts that can wear out but also simplifies routine service and troubleshooting of driveline vibrations or noises. Navara owners looking after their utes should focus their attention on universal joints, driveshaft condition, and fluid levels when servicing the drivetrain.
