Universal Joints and the 2020 Mazda CX-5: What You Need to Know

When it comes to the drivetrain components of the 2020 Mazda CX-5, universal joints are not part of the equation. Unlike some vehicles that use universal joints to transfer power between shafts that operate at an angle, the CX-5 takes a different approach. This is mainly due to the car's front-wheel-drive platform architecture and its engineering choices that favour constant velocity joints instead.

So why does the 2020 Mazda CX-5 not use universal joints? Universal joints, often called U-joints, are typically found in rear-wheel-drive or four-wheel-drive vehicles where there is a need to handle large angles and misalignment between the driveshaft and the differential or transmission. They allow the driveshaft to flex and move while still transmitting torque smoothly.

However, the 2020 Mazda CX-5 primarily uses front-wheel drive with its power delivered to the front wheels via a transaxle. In this setup, constant velocity (CV) joints are the preferred choice. CV joints handle the complex motions required in front-wheel-drive cars, allowing smooth transfer of power even as the wheels turn and the suspension moves. They are designed to maintain constant rotational speed without any noticeable vibration, even when the joint is operating at an angle.

CV joints provide several benefits over universal joints in this application. They offer better efficiency, quieter operation, and greater durability when dealing with the particular angles and movements involved in front-wheel-drive systems. Because the CX-5 is a crossover SUV designed mainly for on-road driving with occasional light off-road use, the CV joints meet all its drivetrain needs effectively.

In contrast, universal joints tend to be bulkier and less smooth compared to CV joints. For the kinds of driving and handling that Mazda aims for with the CX-5, universal joints would not provide any advantages and could, in fact, introduce noise and harsher driveline behaviour.

So, to put it simply, universal joints are not relevant or used on the 2020 Mazda CX-5. Instead, the vehicle relies on CV joints as part of its axle shafts to deliver power to the wheels reliably and smoothly.

That said, understanding universal joints can still be helpful, especially for people who own vehicles with a rear-wheel or four-wheel-drive setup that uses them. Universal joints serve an important role in many drivetrains and require appropriate maintenance to keep things running smoothly.

The purpose of a universal joint is to transmit rotating power between two shafts that are not perfectly aligned with each other. Unlike a CV joint that maintains constant velocity regardless of angle, a universal joint allows the driveshaft to flex while accommodating misalignment and angular movement between components. They are commonly found in rear-wheel-drive vehicles where the driveshaft runs from the transmission to the rear differential, which might sit at a different height or angle compared to the transmission output.

Universal joints are subject to wear over time due to the heavy loads and constant movement involved. If a U-joint begins to fail, it can produce symptoms like vibration, clunking noises when shifting gears or accelerating, and eventually driveline failure if neglected. This is why regular inspection and greasing (if equipped with grease fittings) are recommended maintenance steps.

Here are some general tips for anyone needing to deal with universal joint maintenance or replacement, even though the 2020 Mazda CX-5 does not use them:

• Check for any signs of excessive play in the universal joints by manually moving the driveshaft near the joints. Excessive looseness indicates wear.
• Listen for squeaking or clunking noises while driving, especially during acceleration or deceleration - these can be signs of failing U-joints.
• If the U-joints are greasable, they should be lubricated at regular service intervals using the correct type of grease. This helps extend their lifespan.
• Once a universal joint shows signs of wear or damage, timely replacement is essential to prevent further drivetrain damage or safety issues.

While the 2020 Mazda CX-5 doesn't have universal joints, it's worth noting that its CV joints require their own kind of maintenance. Protecting the CV boots from cracks or tears is crucial because damaged boots allow dirt and moisture in, leading to eventual joint failure. Keeping an eye on these boots and replacing them if necessary is part of ensuring the CX-5's drivetrain stays in top shape.

In the world of modern vehicles, drivetrain technology choices vary greatly depending on the design and intended use of the vehicle. For the CX-5, Mazda has opted for a system that uses CV joints to deliver power smoothly and efficiently, making universal joints unnecessary. So for owners and enthusiasts, understanding this difference is key to knowing how to care for their ride properly and what parts their Mazda depends on to keep moving.
