Centre Bearing on the 2019 Nissan Serena: What You Need to Know

The 2019 Nissan Serena is a popular people mover known for its spacious interior and smooth driving experience. When it comes to drivetrain components like the centre bearing, interestingly, this model does not actually use one. That might leave some wondering why that is and what a centre bearing does in vehicles that do have them, especially since these components are crucial in many other cars, particularly those with longer driveshafts.

A centre bearing is typically found in vehicles that have a two-piece driveshaft setup. Its job is to support the driveshaft somewhere between the gearbox and the rear axle, helping to reduce vibration and keep the driveshaft aligned properly. This is especially important in longer vehicles because a single long driveshaft can be prone to wobbling and excessive wear at high speeds.

However, the 2019 Nissan Serena does not require a centre bearing because of the way its drivetrain is designed. It commonly comes with a front-wheel-drive layout or an all-wheel-drive system that uses independent half-shafts rather than a long, single or two-piece driveshaft running the length of the vehicle. Because the power is delivered relatively close to the front wheels and uses shorter shafts, the need for a centre bearing simply isn't there.

In simpler terms, the Nissan Serena's engine and transmission setup, which usually features a transaxle in the front and direct drive shafts running to the front wheels, means there's no long shaft extending to the back of the vehicle that would need extra support. For the all-wheel-drive versions, power is often transferred through additional gearboxes and shorter shafts, still avoiding the need for a long driveshaft and thus a centre bearing.

Since there is no centre bearing on the 2019 Nissan Serena, there's no centre bearing maintenance or replacement involved. Instead, owners should focus on servicing other drivetrain components such as CV joints, boots, and axles, which are more relevant to the vehicle's actual driveline design.

For drivers who are familiar with vehicles that use centre bearings, knowing why the Serena doesn't have one can help clarify what kinds of wear or noises to expect. Without a centre bearing, there won't be the kind of rumbling or vibration from the middle of the underside of the car that often signals bearing wear in other vehicles. Instead, any driveline noises or issues in Serena models are more likely linked to axle joints or transmission components.

Although centre bearings are not part of the Serena's design, it is useful to understand their purpose in case someone owns multiple vehicles or is dealing with other car models. In vehicles equipped with longer driveshafts, centre bearings help to absorb the load and prevent the driveshaft from bending, which improves drivability and longevity. They also reduce harsh vibrations felt inside the cabin, contributing to a smoother ride.

For vehicles with a centre bearing, regular servicing is recommended. Factors such as wear, grease depletion, and seal failure can affect performance over time. When replacing a centre bearing, it's crucial to make sure the driveshaft is rebalanced so that no undue strain is placed on the new bearing or other components. Indicators that a centre bearing needs attention include unusual noises while accelerating, vibrations at cruising speeds, or visible damage to the bearing support or rubber isolation mounts.

In contrast, 2019 Nissan Serena owners can rest easy knowing they don't have this particular part to worry about. Instead, they should keep an eye on the more relevant components such as the CV axles and suspension parts. Regular servicing will help maintain these elements and ensure the vehicle continues to perform smoothly over the years.
