Parts for your 2018 Mazda Cx-5-Centre bearing

Does the 2018 Mazda CX-5 Have a Centre-Bearing?

When it comes to the drivetrain layout of the 2018 Mazda CX-5, it's important to know whether this vehicle uses a centre-bearing. The centre-bearing, also known as a carrier bearing, is typically found in vehicles with a two-piece driveshaft. Its job is to support the driveshaft where it is split into sections and to reduce vibrations as the shaft spins at high speeds. But does the 2018 Mazda CX-5 actually have one?

The 2018 Mazda CX-5 generally does not feature a centre-bearing. This is because the CX-5 utilises a single-piece driveshaft setup, especially in its front-wheel-drive and all-wheel-drive configurations. The single-piece driveshaft is strong and long enough to span the distance from the transmission or transfer case to the rear differential without needing to be split up. This continuous shaft design eliminates the need for a centre-bearing to provide support mid-shaft.

If that sounds a bit technical, here is why this matters: in longer vehicles or those with specific drivetrain configurations like some trucks or larger SUVs, the driveshaft might be too long to function effectively as one continuous piece. That's where the centre-bearing comes in handy. But in the 2018 Mazda CX-5, the driveshaft length and design do not require support from a centre-bearing, which keeps the drivetrain simpler and potentially more reliable.

Because the CX-5's drivetrain uses a single-piece driveshaft, there is no centre-bearing to service or replace during standard maintenance. This helps reduce overall drivetrain complexity and potential failure points. Mazda's engineering focus on compact and efficient design means that the elimination of unnecessary components like a centre-bearing lowers the chances of drivetrain noise, vibrations, or breakdowns due to worn support bearings.

Additionally, the 2018 Mazda CX-5 is equipped with a well-designed traction and stability control system, in combination with the i-ACTIV all-wheel-drive system on certain models, which provides excellent traction control without the need for additional mechanical supports like a centre-bearing. The simpler drivetrain design also aids fuel efficiency and reduces overall vehicle weight, both big advantages for daily drivers in Australia.

While some AWD SUVs or trucks might incorporate a centre-bearing to handle the extra length of divided driveshafts or to manage torque delivery across stone-filled tracks or rugged off-road terrain, the CX-5's drivetrain doesn't require such components due to its more compact and refined design. By keeping it straightforward, Mazda manages to offer a smooth and high-performing AWD system without extra drivetrain parts that would need regular upkeep.

This absence of a centre-bearing means owners don't have to worry about one more mechanical component failing or needing lubrication, inspection, or replacement. That simplicity is reflected in the vehicle's generally low maintenance costs and reliability across various mileage ranges. For anyone servicing a 2018 Mazda CX-5, typical drivetrain checks focus on CV joints, universal joints, and fluid levels rather than a centre-bearing.

To sum things up for a 2018 Mazda CX-5 owner wondering about the centre-bearing: you do not have one in your CX-5 because your vehicle's driveshaft is designed as a single piece. This design choice results in fewer moving parts, less vibration, and lower maintenance requirements. Instead of fretting about centre-bearing wear, focus your attention on other key areas of drivetrain maintenance like checking the condition of the CV boots, monitoring any unusual noises from the driveline, and keeping drivetrain fluids topped up. Regular servicing and inspections based on the manufacturer's recommendations will ensure that your CX-5's drivetrain continues to perform smoothly for years to come.
