Parts for your 2013 Mazda Axela-Universal joints

Universal Joints on the 2013 Mazda Axela: What You Need to Know

The 2013 Mazda Axela, known internationally as the Mazda3, is a popular compact car in Australia and around the world. Whether you're cruising through city streets or hitting the open road, understanding the components that keep the Axela moving smoothly is important. One common question that pops up is whether universal joints, also known as U-joints, are part of this vehicle's drivetrain.

When looking into the technical setup of the 2013 Mazda Axela, it's clear that universal joints are not typically a component of this vehicle's drivetrain, especially in models equipped with front-wheel drive, which is the most common configuration for the Axela. Instead of universal joints, the Axela uses Constant Velocity (CV) joints on its drive shafts. CV joints serve a similar purpose to universal joints, but with important differences that make them more suited for front-wheel drive cars like the Axela.

Universal joints are mechanical connections that allow shafts to transmit torque despite changes in angle between those shafts. You'll most often find U-joints in rear-wheel drive vehicles with a solid rear axle, where the driveshaft runs from the transmission to the differential at the rear. Because the rear driveshaft has to accommodate up and down movement of the suspension as well as changes in angle, universal joints provide the flexibility needed.

In contrast, the Mazda Axela's front-wheel drive setup uses half-shafts equipped with Constant Velocity joints. CV joints can transmit power efficiently through variable angles without the vibration and increased wear that can be associated with universal joints. This is why the engineering choice for a front-wheel drive car like the Axela is to rely on CV joints, making universal joints unnecessary.

So if universal joints aren't part of the 2013 Axela drivetrain, what does that mean for drivers? For starters, braking, steering and suspension inspection routines do not need to include U-joint checks. Instead, attention should be given to CV joints and drive shafts during servicing and maintenance.

CV joints do require maintenance, although modern, sealed-for-life CV joints generally need less attention than the universal joints in older vehicles. Still, it's worth being aware of the symptoms of CV joint issues, such as clicking noises when turning, vibration during acceleration, or grease leakage from torn CV boots. If left unaddressed, damaged CV joints can lead to more costly repairs or even breakdowns.

Replacement of universal joints, where they do exist, involves removing the driveshaft and pressing out the old joints to install new ones, which can be a labour-intensive task depending on the vehicle. For the Axela, the work focuses on the drive half-shafts, which are simpler to service and replace when needed, usually involving a CV joint and boot kit replacement.

Since the universal joints aren't a feature on the 2013 Mazda Axela, the best course of action for owners is to keep an eye on the boots covering the CV joints. These rubber components can crack or split over time, letting dirt and moisture in, which leads to premature CV joint failure. Regular inspections during servicing can catch potential problems early. A cracked or damaged boot is typically replaced quickly and cheaply compared to repairing a full CV joint or driveshaft assembly.

In summary, the absence of universal joints in the 2013 Mazda Axela comes down to the vehicle's design and drivetrain layout. Front-wheel drive cars like the Axela benefit from the smooth operation and efficiency of CV joints, eliminating the need for U-joints. For owners, maintaining the health of CV joints and boots during regular servicing is key to ensuring the car continues to perform well without unexpected drivetrain problems.
