Parts for your 2013 Mazda Bt-50-Centre bearing

Centre Bearing on the 2013 Mazda BT-50

The 2013 Mazda BT-50 is a robust and popular utility vehicle, well-loved for its durability and performance. When it comes to its drivetrain design, particularly concerning the propeller shaft (or driveshaft), many might wonder if a centre bearing plays a role in this model. After digging into the technical aspects of the 2013 Mazda BT-50, it turns out that a centre bearing is simply not a component fitted or required on this vehicle.

So why doesn't the 2013 Mazda BT-50 have a centre bearing? The key lies in how the drivetrain is laid out. The centre bearing is often used on vehicles with a longer or split driveshaft. It supports the middle section of the driveshaft, reducing vibration and enhancing stability when the shaft length requires it to be divided into two parts. This setup is common on larger four-wheel-drive vehicles where the distance between the transmission and rear differential is quite long, necessitating a two-piece shaft supported by a centre bearing.

In the 2013 Mazda BT-50, however, the driveshaft is designed as a single-piece shaft linking the transfer case directly to the rear differential. Because the shaft is relatively short and straightforward in its design, there is no need for an intermediate support like a centre bearing. The single-piece driveshaft can handle the torque and rotational forces adequately without the extra support.

This simpler driveshaft layout also reduces the number of moving parts, which can mean fewer components needing maintenance or replacement down the track. The absence of a centre bearing is part of Mazda's engineering approach to make the BT-50 a practical and reliable ute that can handle Australian conditions without unnecessary complexity.

So where does this leave anyone curious about centre bearings and the BT-50? Essentially, when maintaining or servicing a 2013 Mazda BT-50, there is no centre bearing to check, replace or service because it is not part of the vehicle's drivetrain design.

Instead, owners should focus on components that do play a crucial role in the driveshaft's operation, such as the universal joints (U-joints), driveshaft balancing, and the rear differential seals. These parts are more relevant in terms of wear and tear and servicing requirements.

That said, having a good understanding of what a centre bearing does is always helpful for vehicle knowledge, especially when switching between different 4x4 trucks or commercial vehicles that might have this component.

Centre bearings are designed to support the driveshaft in the middle, preventing excessive vibration and wear when the shaft length demands a split design. You'll often find centre bearings on long-wheelbase vehicles or heavy-duty utes with a two-piece driveshaft setup. They help maintain the driveline's alignment and reduce noise, vibration, and harshness (NVH) by ensuring the shaft spins smoothly and accurately.

When a centre bearing is fitted, regular inspection and maintenance are recommended. This includes checking for signs of wear such as excessive play, unusual noises, or visible damage to the bearing's rubber mount. Failure to catch issues early could lead to driveline vibrations, increased wear on the driveshaft and U-joints, or even failure that might leave the vehicle stranded.

Routine servicing typically involves greasing the bearing if it's serviceable, tightening any loose bolts, and replacing the centre bearing unit when signs of wear are evident. Replacement is usually straightforward but should be done with care to maintain proper driveshaft alignment and balance.

While the 2013 Mazda BT-50 does not require any of this for a centre bearing, it's a good idea for owners to keep an eye on the drivetrain for any unusual noises or vibrations, ensuring the driveshaft and related components like U-joints and seals remain in good shape. Regular maintenance following the manufacturer's schedule helps keep the BT-50 running smoothly and ready for whatever Aussie adventures lie ahead.
