Parts for your 2019 Mazda Cx-5-Centre bearing

Does the 2019 Mazda CX-5 Use a Centre-Bearing?

The 2019 Mazda CX-5 is a popular compact SUV known for its smooth handling, efficient performance, and sleek design. When it comes to its drivetrain components, many people wonder if it features a centre-bearing, especially if they're familiar with vehicles that do. After checking reliable technical sources and service manuals specific to the 2019 Mazda CX-5, it becomes clear that this vehicle does not use a centre-bearing in its drivetrain.

So why isn't a centre-bearing part of the CX-5's setup? It mainly comes down to the type of drivetrain layout Mazda employs in this model. The 2019 CX-5 is either front-wheel drive or i-Activ all-wheel drive. Both configurations use a drivetrain system that does not require a centre-bearing because they do not have a very long driveshaft that spans from the front to the rear requiring support along the way.

The centre-bearing is a component typically found in vehicles that have a two-piece or multi-piece driveshaft. When a long driveshaft is necessary, a centre-bearing is fitted to hold and locate the driveshaft securely, preventing vibrations and enhancing stability. This is common in rear-wheel-drive or four-wheel-drive trucks and larger SUVs with a body-on-frame design and longer wheelbases, where the length of the drivetrain needs additional support to reduce shaft whip and noise.

The Mazda CX-5, by contrast, uses a more compact drivetrain layout with a single-piece driveshaft for the all-wheel-drive models, and front-wheel-drive versions don't have a rear driveshaft at all. With shorter drivetrain components and a unibody chassis, there's little to no need to have an extra bearing supporting the driveshaft in the middle of the vehicle.

Without the need for a centre-bearing, the Mazda CX-5 benefits from fewer moving parts, potentially lower maintenance requirements, and simpler servicing for drivetrain-related components. In essence, the absence of a centre-bearing speaks to Mazda's efficient engineering approach for the CX-5's drivetrain design.

For those curious about the centre-bearing itself in vehicles that do use one, here's a brief overview of what it does and important tips for replacement and maintenance, useful knowledge if you're ever dealing with different vehicles down the track.

On vehicles equipped with a two-piece driveshaft, the centre-bearing serves a crucial role. It acts as a support point for the driveshaft, holding it in place under the vehicle and reducing vibration by providing a stable mounting point. The bearing takes up the mechanical load and helps keep the shaft aligned properly during rotation. This is vital for preventing premature wear on drivetrain components and eliminating driveline noise and harshness inside the cabin.

Over time, a centre-bearing can wear out due to constant rotation, road shocks, and exposure to elements like dirt and moisture. Worn centre-bearings often present symptoms such as clunking noises when shifting gears, vibration felt through the floor or seats at certain speeds, or even difficulty in controlling rear-wheel alignment. When these signs emerge, it's important to have the bearing inspected and replaced if necessary to avoid further damage to the driveshaft or transmission.

Replacing a centre-bearing usually involves removing the driveshaft assembly from the vehicle, separating the two shaft sections, swapping out the old bearing for a new one, and then re-installing everything carefully. It's a job best done by experienced technicians, given the importance of keeping the driveshaft balanced and aligned correctly. An improperly installed or unbalanced driveshaft can lead to increased vibration and further premature wear.

Routine maintenance tips for vehicles with a centre-bearing include regular visual inspections during service intervals, especially if the vehicle is driven in harsh conditions or off-road, where impacts and dirt ingress might accelerate wear. Lubrication isn't usually necessary as most centre-bearings are sealed units, but it's still good to keep the surrounding area clean and check for any signs of corrosion or damage to the mounting brackets.

Even though the 2019 Mazda CX-5 doesn't require a centre-bearing, understanding the part is valuable for Mazda owners who might also deal with other vehicles or older models that use this component. It highlights how drivetrain designs differ across vehicle types and how those differences shape the parts and maintenance needs a car requires.

In the end, with the Mazda CX-5's clever drivetrain layout, motorists can enjoy a solid, low-maintenance ride without worrying about centre-bearing issues. This is one less part to keep an eye on, allowing Mazda drivers to focus more on enjoying the drive and less on frequent drivetrain repairs.
