Universal Joints on the 2015 Mazda CX-5: Are They Used and What You Need to Know

When talking about the drivetrain components of the 2015 Mazda CX-5, especially with regard to universal joints, it is important to know whether this vehicle actually uses them. Universal joints, often shortened to U-joints, are common on many four-wheel drive and rear-wheel drive vehicles, but the 2015 Mazda CX-5 is a bit different when it comes to its drivetrain setup.

The 2015 Mazda CX-5 primarily comes with either front-wheel drive or all-wheel drive configurations. In the front-wheel drive (FWD) variant, power is delivered to the front wheels via constant velocity (CV) joints rather than universal joints. CV joints are specially designed to handle the steering angle and suspension movement smoothly, making them the preferred choice for front-wheel drive vehicles.

Even for the all-wheel drive (AWD) versions of the CX-5, universal joints are generally not the go-to option. Instead, this vehicle uses a combination of CV joints and internal driveshaft components designed for AWD systems that demand consistent torque delivery and smooth articulation.

So, in short, the 2015 Mazda CX-5 does not typically use universal joints. Rather, it relies heavily on CV joints and other specialised drivetrain components to manage power transfer efficiently and quietly.

Why is this the case? Well, universal joints are excellent for setups where there are significant angular movements between connected shafts, such as in rear-wheel drive vehicles with solid rear axles or older four-wheel drive systems. They allow the driveshaft to flex and rotate even when the angle between the shafts changes dramatically.

The CX-5's drivetrain layout, however, is more complex. It requires joints that can handle not just rotation but also the side-to-side and up-and-down movements associated with steering and suspension changes - all while minimising noise and vibration. CV joints meet these demands much better than universal joints.

CV joints are built with a special ball bearing mechanism that keeps power transmission smooth throughout a wide range of motion. This helps deliver consistent torque without the vibration or drivetrain lash that can sometimes be experienced with universal joints, particularly when operating at higher angles or speeds.

Given that universal joints are not used on the 2015 Mazda CX-5, maintenance and servicing focus primarily on the CV joints and associated driveshaft components. It is recommended to keep an eye on the CV joint boots - the rubber coverings protecting the joints from dirt, water, and grime. Any cracks or tears in those boots can lead to premature joint failure as contaminants enter the joint and damage the bearings.

Regular inspection of these boots during scheduled servicing can help catch issues early. If a damaged boot is found, replacing it promptly along with re-greasing the joint can save you from having to replace the entire joint - or worse, the driveshaft. Likewise, listen for unusual clicking or popping noises when turning, as this may indicate a CV joint is starting to wear out and could require replacement.

In the rare case that any driveshaft-related issues arise, a qualified mechanic can assess the entire assembly, including hubs, joints, and shafts, to ensure everything is operating smoothly. Because the CX-5's AWD system is quite sophisticated, working on these parts requires specific knowledge and tools to maintain the vehicle's handling and safety.

It is worth noting that while universal joints are not part of the CX-5's power delivery, Mazda engineers have designed the vehicle's drivetrain components to balance performance, comfort, and reliability. This means owners can generally expect smooth drives and fewer drivetrain maintenance hassles compared to vehicles with older-style drivetrains relying on universal joints.
