Centre Bearing on the 2016 Mazda CX-9: What You Need to Know

When it comes to the 2016 Mazda CX-9, the topic of a centre bearing often comes up, especially among those interested in drivetrain components. Simply put, the 2016 Mazda CX-9 does not have a centre bearing fitted in its drivetrain. This is because of the vehicle's drivetrain layout and design, which makes a centre bearing unnecessary.

So, why is there no centre bearing on the 2016 Mazda CX-9? The answer lies in the type of drivetrain it uses. The CX-9 is equipped with a front-engine, front-wheel-drive layout as standard, with an available all-wheel-drive option that uses an on-demand AWD system. The drivetrain components, including driveshafts and axles, are relatively short and straightforward compared to vehicles with more complex, longer driveline setups such as some rear-wheel-drive or four-wheel-drive trucks and SUVs. Vehicles that have a long driveshaft running between the transmission and the rear differential often require a centre bearing to support the shaft at a midpoint and reduce vibrations. Since the CX-9's drivetrain does not feature a long, continuous driveshaft like this, there simply isn't a need for a centre bearing.

In practical terms, the CX-9's AWD system uses multiple shorter shafts and more compact components which do not need intermediate support from a centre bearing. Its design inherently minimises rotational instability and vibration without requiring additional support hardware that a centre bearing would provide.

Now for those curious about centre bearings in general, here's a bit more detail. A centre bearing, also known as a carrier bearing, is typically used on vehicles with a two-piece driveshaft. This bearing is mounted on the vehicle's chassis and supports the driveshaft where it is split into two sections. The main functions of the centre bearing are to hold the driveshaft in place, reduce vibrations, and allow the driveshaft sections to spin smoothly in alignment. This not only prevents drivetrain wear but also improves driving comfort by reducing noise and vibration felt inside the cabin.

On vehicles that do have a centre bearing, it's an important service component. Over time, the rubber isolator and internal bearing wear out due to road conditions, drivetrain loads and exposure to the elements. Common signs of a failing centre bearing include noticeable vibrations when driving, a howling or whining sound at certain speeds, or even clunking noises during acceleration and deceleration.

When it comes to servicing a centre bearing, regular inspection is key. Mechanics often check for excessive play in the bearing, cracks or damage in the rubber isolator, and signs of rust or corrosion. If any of these symptoms are found, the centre bearing will need replacement. Neglecting a worn centre bearing can lead to further drivetrain damage and more costly repairs down the track.

Because the 2016 Mazda CX-9 does not use a centre bearing, owners do not need to worry about this kind of maintenance or replacement. Instead, attention should be focused on other drivetrain components like constant velocity (CV) joints, drive axles, and the AWD system's differentials. Regular servicing of these parts will keep the vehicle running smoothly and avoid drivetrain issues.

In short, the absence of a centre bearing in the CX-9 is a reflection of its efficient and modern drivetrain design. It reduces unnecessary complexity and maintenance points, meaning fewer parts that can wear out and cause issues. This contributes to the overall reliability and smooth performance that Mazda is known for with this SUV.
