Centre Bearing on the 2016 Nissan X-Trail: What You Need to Know

When looking into the driveline components of the 2016 Nissan X-Trail, you might wonder whether a centre bearing plays a role in this vehicle's setup. After checking through technical sources and workshop manuals for this popular SUV, it becomes clear that the 2016 Nissan X-Trail does not use a centre bearing. Instead, the vehicle's drivetrain design and layout make the fitting of a centre bearing unnecessary.

Why is there no centre bearing on the 2016 Nissan X-Trail? The answer comes down to the way the X-Trail is engineered. The vehicle features a relatively simple drivetrain architecture. Models equipped with all-wheel drive (AWD) typically employ a shorter and more compact prop shaft system that does not require intermediate support. Centre bearings are generally found on vehicles with longer, multi-piece propeller shafts that need to be supported mid-way to reduce vibration and maintain balance. Since the X-Trail's prop shaft is shorter and often single-piece, there is no need for a centre bearing to hold it in place.

In addition, the Nissan X-Trail's chassis and drivetrain layout have been designed to keep drivetrain components as straightforward and robust as possible. This reduces complexity and potential points of failure. Centre bearings can introduce another wear point and require maintenance, so from a design perspective, avoiding their need benefits reliability and decreases maintenance costs.

Vehicles with long or two-piece driveshafts, such as some commercial trucks, older four-wheel-drive vehicles, or large SUVs, usually have centre bearings to handle the extra length and prevent shaft whip or vibrations under load. Since the 2016 Nissan X-Trail does not fit those criteria, it doesn't have nor need a centre bearing.

For owners and mechanics, this means servicing the driveshaft area is simpler and there is no centre bearing to check, grease, or replace. Instead, maintenance focuses on other drivetrain elements such as universal joints (U-joints), CV joints, and the differential. Regular inspections and lubrication of these parts help keep the drivetrain running smoothly.

That said, let's take a look at what a centre bearing actually is, and what role it plays on the vehicles that do have them.

A centre bearing is a type of support bearing mounted on the vehicle chassis or crossmember designed to support a multi-piece driveshaft assembly. Long driveshafts transmit power from the transmission or transfer case to the differential at the rear axle. When the driveshaft is long enough, it is often split into two parts connected by a centre bearing. This bearing reduces vibrations, prevents driveshaft flexing, and enhances overall stability of the driveline.

Without a centre bearing on long shafts, vehicles can experience increased noise and driveline vibrations, which can lead to premature wear and failure. The centre bearing keeps the driveshaft aligned and balanced, supporting the rotating components and absorbing some of the stresses caused by engine torque and road conditions.

When it comes to maintaining a centre bearing, regular checks during vehicle servicing are important. Typically, the centre bearing is housed in a rubber or polyurethane mount that isolates vibration. Over time, this mount can degrade, crack or become loose, affecting the performance of the bearing and causing driveline noise or vibrations.

Replacing a worn centre bearing should be done promptly to avoid damage to the driveshaft or the vehicle's transmission and differential components. The procedure usually involves removing the driveshaft assembly, inspecting the bearing and mount, and installing a new bearing if required. It is recommended to get this replacement done by professionals who have the correct tools and experience to balance the driveshaft after installation.

In some vehicles that require it, lubricating the centre bearing during regular servicing can extend its life. However, many modern centre bearings are sealed units designed to be maintenance-free until they need to be replaced. It's always best to consult the vehicle's service manual for specific instructions related to your car model.

While the 2016 Nissan X-Trail doesn't have a centre bearing to worry about, understanding this part's role helps put into perspective the design decisions that manufacturers make for driveline reliability and ease of maintenance. X-Trail owners can rest easy knowing one less thing means fewer complications and generally more straightforward upkeep.

If you're looking after your X-Trail's drivetrain, just focus on the usual suspects such as universal joints, CV joints, and differential fluid changes. These areas will keep your 2016 Nissan X-Trail running smoothly without any hassle related to centre bearings.
