Centre Bearing on the 2014 Mazda Premacy: Purpose and Maintenance

The 2014 Mazda Premacy, also known as the Mazda5 in some markets, is a compact multi-purpose vehicle that primarily uses a front-wheel-drive layout, with some versions offering all-wheel drive. When it comes to drivetrain components like the centre bearing, technical sources and repair manuals indicate that the 2014 Mazda Premacy does not typically use a centre bearing in its drivetrain setup. This is an important point to understand for anyone looking to maintain or repair this vehicle.

A centre bearing is most commonly found on vehicles with a two-piece driveshaft, usually designed for rear-wheel or all-wheel-drive systems where the driveshaft is split into two sections. The centre bearing supports the intermediate shaft to reduce drivetrain vibrations and maintain alignment, allowing the shaft to spin smoothly and transfer power efficiently between the transmission and the rear differential.

In the case of the 2014 Mazda Premacy, the standard models rely on a front-wheel-drive configuration where the power is delivered directly from the transaxle to the front wheels through half shafts. The AWD variant uses a different arrangement involving a transfer case and propeller shaft, but it typically features a full-length prop shaft rather than a split driveshaft with a centre bearing.

Because the Premacy's drivetrain does not consist of a two-piece driveshaft requiring intermediate support, there is no centre bearing fitted to these vehicles. Without the need to support an intermediate shaft, the centre bearing is not necessary for maintaining drivetrain integrity in this model.

Understanding why the centre bearing isn't used helps clarify the design priorities of the Mazda Premacy. The transverse engine and front-wheel-drive layout allow for a more compact drivetrain system, cutting down on complexity and potential maintenance parts like the centre bearing. This simplicity helps keep both production costs and repair expenses lower compared to vehicles with more complex drivetrain systems that incorporate longer or split driveshafts.

For those who own a 2014 Mazda Premacy, this means there is no need to worry about centre bearing wear, replacement, or associated noises such as rumbling or vibration from a failing bearing. Instead, owners should focus on other aspects of the vehicle's powertrain and suspension that are more likely to need regular servicing.

That said, it's always wise to keep an eye on other drivetrain components such as the CV joints, half shafts, and transmission mounts, especially as the vehicle ages or accumulates higher kilometres. These parts play a vital role in smooth power delivery and ride comfort and are far more likely to need maintenance than a part that isn't even present.

For AWD Premacy models that have a prop shaft running to the rear, they typically use a single solid shaft without a centre bearing, supported instead by universal joints designed to accommodate the shaft's length and movement. These components have their own maintenance requirements but do not involve a centre bearing either.

In short, anyone servicing a 2014 Mazda Premacy can safely disregard the centre bearing when doing routine maintenance or drivetrain inspections. The absence of a centre bearing in this car reflects a straightforward drivetrain design optimised for efficiency, reliability, and ease of maintenance. This also means fewer parts to check, less chance of drivetrain vibration issues due to bearing failure, and a simpler layout overall.
