Centre Bearing on the 2014 Nissan Pathfinder: What You Need to Know

The 2014 Nissan Pathfinder does not typically use a centre bearing in its drivetrain setup. This might come as a surprise to some, especially those familiar with vehicles that have long driveshafts requiring additional support. To understand why the 2014 Pathfinder skips this component and what it means for owners, it helps to look at how the vehicle is designed and what a centre bearing actually does.

A centre bearing is usually found in vehicles that have a split driveshaft, meaning the driveshaft is made up of two sections connected by a support in the middle. This support is the centre bearing, and it keeps the driveshaft properly aligned and reduces vibrations as the shaft spins around at high speed. The bearing is mounted on a bracket, usually attached to the chassis, and acts like a stabiliser for the rotating shaft, preventing wobbling and premature wear. Without a centre bearing, a longer, unsupported driveshaft could flex or vibrate excessively, leading to an uncomfortable ride and potential damage over time.

However, the 2014 Nissan Pathfinder employs a different type of drivetrain arrangement which typically does not call for a centre bearing. Most versions of this model are equipped with a single, one-piece driveshaft or a transaxle layout that does not extend the length of the driveshaft enough to require that additional support. The typical setup in the 2014 Pathfinder involves either a front-wheel-drive system or an all-wheel-drive system utilising a shorter driveshaft and constant velocity (CV) joints, which allow for smooth power transmission without the need for an intermediate support bearing.

Because the driveshaft in the 2014 Pathfinder is relatively short and robust, the natural vibration dampening and structural integrity of the shaft itself mean the centre bearing is not necessary. This design choice keeps the drivetrain simpler, reduces weight and eliminates an extra potential failure point. For owners, this means there's less to worry about when it comes to centre bearing maintenance or replacement!

So what exactly does this mean for Pathfinder owners when it comes to servicing or upkeep? Since the centre bearing is not part of the 2014 Pathfinder's drivetrain, there is no need for regular maintenance, inspection or replacement of this component. Instead, maintenance focuses on other drivetrain parts like the CV joints, universal joints, and the driveshaft itself.

When servicing the drivetrain on a 2014 Nissan Pathfinder, it's a good idea to have a mechanic check the condition of these elements. CV joints in particular play a crucial role in delivering power smoothly to the wheels and are prone to wear over time, especially their protective boots which can crack or split if exposed to road debris, dirt or harsh weather conditions. Worn or damaged CV joints can cause clicking noises during turns and may eventually fail, leading to costly repairs. Regular servicing, such as inspection and greasing where applicable, helps keep these parts running without issue.

Universal joints or U-joints, if fitted, are also a critical part of the driveshaft assembly that allow for flex in the drivetrain when driving over bumps or between the engine and rear wheels. These usually require periodic inspection for wear and proper lubrication in vehicles that use them.

For the 2014 Pathfinder, it's also worth mentioning that the vehicle's design strives for durability and reliability, meaning many drivetrain parts are engineered to last long periods with minimal intervention. Nevertheless, keeping an eye (or ear) out for unusual vibrations or noises when driving could signal the need for a mechanic to inspect the driveshaft and related components. Prompt attention to these signs can extend the life of the drivetrain and help avoid more extensive repairs later on.

In short, the absence of a centre bearing on the 2014 Nissan Pathfinder is a deliberate design aimed at efficiency and simplicity. The drivetrain layout, featuring a mostly one-piece driveshaft and well-engineered CV joints, does not require the additional support that a centre bearing would provide. This means fewer parts to maintain and a more straightforward approach to servicing the vehicle's power transmission system.

Owners should maintain regular servicing intervals based on Nissan's recommendations, paying special attention to CV joints, universal joints and the driveshaft itself. By sticking to regular inspections and addressing any abnormalities early, the 2014 Pathfinder's drivetrain should deliver reliable performance for many years without the hassles associated with centre bearing upkeep.
