Parts for your 2016 Nissan Pathfinder-Centre bearing

Understanding the Role of the Centre Bearing in a 2016 Nissan Pathfinder

When it comes to the driveshaft setup on the 2016 Nissan Pathfinder, the topic of a centre bearing often pops up. A centre bearing is a component commonly found in vehicles that have a two-piece driveshaft system. It supports the driveshaft at a midpoint, helping to reduce vibrations and maintain proper alignment as power is transmitted from the transmission to the rear differential. But does the 2016 Nissan Pathfinder actually use one?

After looking at the technical design and drivetrain layout of the 2016 Nissan Pathfinder, it becomes clear that the vehicle does not use a centre bearing in its driveline setup. The 2016 Pathfinder features a unibody chassis and a front-wheel-drive based layout with available all-wheel drive, meaning it does not utilise the traditional two-piece driveshaft arrangement found in many rear-wheel-drive or body-on-frame vehicles. Instead, it typically employs a single-piece driveshaft when sending power to the rear wheels in AWD variants.

So why is there no centre bearing on the 2016 Pathfinder?

The absence of a centre bearing in this vehicle comes down to its architecture. Centre bearings are mostly needed in vehicles where a driveshaft is split into two pieces to manage overall length and prevent issues associated with vibrations and shaft deflection. Since the Pathfinder uses a relatively short, single-piece driveshaft for its AWD system, the need for a centre bearing is eliminated.

In vehicles that do use a two-piece driveshaft with a centre bearing, that bearing plays a crucial role in keeping the driveshaft supported and running smoothly. It acts as an intermediary support, absorbing some of the stresses and preventing the shaft from flexing too much during operation. The centre bearing sits in a bracket attached to the vehicle's chassis and cushions the driveshaft, helping extend the life of the drivetrain parts.

For those Nissan owners who do have vehicles with centre bearings, it's important to keep the bearing in good condition. Centre bearings need regular inspection because worn or damaged bearings can cause vibrations, noise, and eventually damage to the driveshaft and other components. Signs of a failing centre bearing include unusual rumbling noises from under the vehicle, increased vibrations felt through the floor, or clunking sounds when accelerating or decelerating.

Replacing or servicing a centre bearing involves removing the driveshaft from the vehicle, detaching the worn bearing, and installing a new one. Since this component is mounted to the chassis, technicians must carefully realign the driveshaft on refitting to make sure everything spins true and smooth. Some workshop tips include lubricating the bearing mates if applicable, ensuring the centre bearing bracket bolts are torqued to spec, and checking the driveshaft for any bends or wear during the process.

Regular maintenance routines designed for vehicles with centre bearings typically recommend checking the bearing condition at every service interval, especially if the vehicle covers a lot of rough terrain or lots of kilometres each year. Keeping an eye on driveline noises and vibrations can help catch early signs of centre bearing wear before it transforms into more costly drivetrain repairs.

Given the design of the 2016 Nissan Pathfinder, drivers don't have to worry about centre bearing upkeep since the part isn't part of its driveshaft assembly. Instead, maintenance focus should be placed on other relevant drivetrain components such as the CV joints, drive axles, and universal joints where applicable. However, understanding how a centre bearing functions can be helpful when comparing drivetrain designs across different vehicles or when servicing other Nissan models that might use a two-piece driveshaft configuration.

At the end of the day, the 2016 Pathfinder's drivetrain gets the job done without the need for a centre bearing. This means fewer parts to worry about, potentially reducing maintenance tasks for owners who want straightforward reliability and smooth AWD performance. Owners should consult their Nissan service manual or authorised service centre for specific advice on driveline inspection and maintenance tailored to their Pathfinder's setup.
