Centre Bearing on the 2020 Mazda BT-50: Is It Used and What You Need to Know

The 2020 Mazda BT-50 is a popular ute in Australia, appreciated for its robust performance and practicality. When it comes to driveline components like the centre bearing, it's important to understand whether this part is relevant to the vehicle and what role it plays in similar setups.

After reviewing technical sources and driveline designs for the 2020 Mazda BT-50, it appears that this particular model does not utilise a centre bearing on its driveshaft. The BT-50 typically features a single-piece or a two-piece driveshaft system depending on the variant and drivetrain configuration, but the 2020 model does not include a centre bearing as part of its factory driveline setup.

So why does the 2020 Mazda BT-50 not have a centre bearing? The reason mostly comes down to the length and design of its driveshaft. Centre bearings are generally used in vehicles with a two-piece driveshaft, where a long driveshaft is split into two sections supported by a bearing mounted somewhere midway underneath the vehicle chassis. This bearing supports and stabilises the driveline, helping to reduce vibration and wear. The BT-50's driveshaft, however, is typically short enough to operate without needing this additional support point.

Because the driveshaft lengths in the 2020 BT-50 do not exceed what can be effectively supported by the standard universal joints at each end, the engineering team did not include a centre bearing. It means there's less complexity, fewer parts to maintain, and one less potential source of driveline noise or failure. The design keeps maintenance a bit simpler for owners, which is always a bonus if you're on the tools or relying on service shops.

Though the 2020 Mazda BT-50 does not use a centre bearing, understanding what a centre bearing does can be helpful, especially if you own other vehicles or happen to come across off-road setups and models that do feature one. Centre bearings are a critical part for any vehicle that uses a two-piece driveshaft, which is common in larger 4x4 trucks, SUVs, and vans where the distance from the transmission to the rear differential is too long for a single shaft to perform well without some help.

Basically, the centre bearing acts as a midway support point for the driveshaft. It holds the driveshaft in place under the chassis, preventing flexing and wobbling as power is transferred from the engine to the rear wheels. This stabilisation reduces vibrations that are felt inside the cabin and minimises the wear on the universal joints themselves. Protecting these components from excessive movement or stress extends the life of the driveline and improves overall vehicle smoothness.

In a vehicle fitted with a centre bearing, regular inspection and maintenance are important to keep everything running smoothly. Centre bearings consist of a metal bracket, a rubber isolator, and a bearing itself. Over time, the rubber can degrade, and the bearing can become noisy or seize up due to dirt ingress, water, or lack of lubrication.

Here are some helpful tips for maintaining a centre bearing if your vehicle is fitted with one:

• Check for vibration or unusual noises. If you start noticing a thumping, rattling, or excessive vibration, it might be a sign the centre bearing is wearing out.
• Regularly inspect the rubber mount. Look for cracks, splits, or hardened rubber, which means it is no longer cushioning the driveshaft effectively.
• Listen for bearing noise. A rumbling or grinding noise when the vehicle is moving can indicate the bearing itself is failing.
• Greasing and lubrication. Some centre bearings are sealed and maintenance-free, but others may require periodic application of grease to keep things running smoothly.
• Immediate replacement if faulty. Driving with a damaged centre bearing can cause accelerated wear on other driveline components and lead to bigger repair bills down the track.

Replacing a centre bearing is often straightforward for a qualified mechanic, but for enthusiasts or do-it-yourselfers, it can be a manageable task with the right tools. The process typically involves supporting the driveshaft, removing the retaining bolts on the bearing bracket, and sliding off the old bearing unit before fitting the new one. It's also a good opportunity to check the entire driveshaft for signs of wear or damage.

All up, the 2020 Mazda BT-50's absence of a centre bearing is thanks to smart engineering and the design choices around its driveline layout. Owners benefit from fewer parts to worry about and a straightforward setup that is easier to maintain. However, anyone interested in driveline health should be aware of what a centre bearing does, especially if they work on or own vehicles where this component is present.

So while the 2020 BT-50 runs solid without one, knowing the role of a centre bearing can help when servicing other vehicles or diagnosing driveline issues elsewhere. Keeping an eye on driveline components - bearings, universal joints, and shafts - is always a good idea to ensure smooth power delivery and a comfortable ride out on the road or trail.
