Parts for your 2018 Nissan Serena-Centre bearing

Understanding the Centre-Bearing on the 2018 Nissan Serena

The 2018 Nissan Serena is a popular people mover in Australia, known for its spacious interior and smooth driving experience. When it comes to drivetrain components like the centre-bearing, many owners wonder if this part is relevant to their vehicle. After checking technical sources and vehicle specifications, it turns out that the 2018 Nissan Serena does not use a centre-bearing in its drivetrain setup.

To explain why, it's important to understand what a centre-bearing actually is and when it's typically found in vehicles. A centre-bearing is a support bearing positioned in the middle of a long driveshaft, often used in vehicles with a two-piece or multi-piece driveshaft configuration. Its main role is to hold the driveshaft securely in place while allowing it to spin freely, reducing vibrations and wear on other drivetrain components. Centre-bearings are crucial in vehicles with longer wheelbases or where the driveshaft is split to manage the distance between the gearbox and the rear differential.

However, the 2018 Nissan Serena generally uses a front-wheel drive (FWD) layout in most markets, including Australia. FWD vehicles typically have a shorter driveshaft (also known as drive axles) that directly connect the transaxle to the front wheels. Since the driveshaft in this setup is quite short and usually a single piece, there is no need for a centre-bearing to provide support mid-shaft. The simplicity of the FWD design also helps reduce maintenance points and potential failure issues like those that can occur with centre-bearings.

In some versions or markets, the Serena might come with an all-wheel drive (AWD) system, but even in those cases the rear driveline parts do not commonly employ a centre-bearing in the way that rear-wheel drive (RWD) or large commercial vehicles do. AWD drivetrains in passenger vehicles often use different configurations, such as separate shafts or constant velocity joints, to manage power delivery without needing a mid-shaft support bearing like a centre-bearing.

So, what does this mean for Nissan Serena owners? Essentially, they don't need to worry about inspecting or maintaining a centre-bearing because it simply isn't fitted. This can be a positive in terms of vehicle upkeep, as it means one less component to monitor for wear or failure, which could otherwise lead to vibrations, noise, or drivetrain damage.

Instead, Nissan Serena owners should focus more on other maintenance tasks related to the drivetrain, such as checking the condition of drive axles and CV (constant velocity) joints, which are critical in transmitting power smoothly to the wheels. Faulty CV joints can cause clicking noises during turns or vibration under acceleration, so regular inspection and replacement are essential to keep the vehicle running smoothly.

Additionally, routine servicing items like transmission fluid changes and differential oil checks (where applicable) will help ensure the longevity and performance of the drivetrain components on a Nissan Serena. These maintenance tasks contribute more directly to the vehicle's reliability than any centre-bearing replacement, as there just isn't one to service.

To sum up, the 2018 Nissan Serena's drivetrain design eliminates the need for a centre-bearing. Its front-wheel drive foundation and drivetrain architecture allow it to run smoothly without this component, which simplifies maintenance and reduces potential failure points. Drivers can breathe easy knowing that there's no centre-bearing to check or replace, and instead should focus their attention on the parts that matter most for their Serena's drive quality and safety.
