Parts for your 2021 Mitsubishi Asx-Universal joints

Universal Joints on the 2021 Mitsubishi ASX: What You Need to Know

When diving into the mechanical components of the 2021 Mitsubishi ASX, you might come across terms like universal joints and wonder if they play a role in this vehicle. Universal joints, often shortened to U-joints, are crucial components in many drivetrains, especially in rear-wheel drive and four-wheel drive vehicles with solid axles. However, the 2021 Mitsubishi ASX, a popular compact SUV in Australia, does not typically utilise universal joints in its drivetrain. Here's why that is and what it means for the modern driver.

The 2021 Mitsubishi ASX is built around a front-wheel drive platform, with an optional all-wheel drive system depending on the variant. The car features a transversely mounted engine paired with a transaxle, which integrates the transmission and differential into one unit. This setup allows power to be delivered more directly to the front wheels through constant velocity (CV) joints rather than universal joints.

Unlike universal joints, CV joints provide smoother power transmission at varying angles and speeds, which is essential for front-wheel drive and all-wheel drive vehicles with independent suspension. CV joints handle the complex movements of the front wheels during steering and suspension travel better than traditional U-joints. This makes universal joints essentially redundant in the drivetrain of the 2021 Mitsubishi ASX.

So why exactly aren't universal joints fitted to the Mitsubishi ASX? It primarily comes down to design and vehicle dynamics. Universal joints excel in setups where the driveshaft has to transmit power over longer distances and at changing angles, such as in rear-wheel drive cars or trucks with solid rear axles. Their design allows them to cope with misalignment between driveshaft components while still transmitting torque effectively.

The ASX's drivetrain, on the other hand, uses a layout where the powertrain sits transversely, and the front wheels are directly driven through half shafts equipped with CV joints. These CV joints are better suited for this configuration due to their ability to handle variable steering angles and suspension articulation. Plus, they operate more smoothly and quietly than universal joints, contributing to a refined driving experience.

Now, while the ASX doesn't use traditional universal joints, it's important to keep an eye on the condition of the CV joints and their boots. CV joints can wear out or fail if their protective boots are damaged, which lets dirt and moisture in. This could lead to clicking noises when turning, vibrations while driving, or even a loss of power delivery to the wheels if the joint fails completely. Regular servicing checks can help spot these issues early and avoid costly repairs.

Universal joints still have plenty of relevance across many other vehicles, especially in trucks, SUVs with solid rear axles, and rear-wheel drive platforms. These components allow the driveshaft to flex and transmit torque even when the angles between the transmission and the axle vary. Maintenance usually involves checking for excessive play, lubrication if applicable, and replacing worn-out joints promptly to prevent drivetrain damage.

For Mitsubishi ASX owners, the takeaway is to focus on the CV joints and boots as part of your regular maintenance routine. Service intervals often recommend inspecting these during tyre rotations or scheduled services. If the rubber boots are torn or leaking grease, it's a good idea to repair or replace them before the CV joints incur damage.

In short, universal joints do not form part of the drivetrain on the 2021 Mitsubishi ASX due to its front-wheel drive-based layout that uses CV joints instead. Understanding this helps clarify why different vehicles have varying components based on their engineering design. While universal joints remain essential in certain types of vehicles, the ASX benefits from a drivetrain setup that focuses on efficiency, smoothness and reliability with CV joints.

If you own a 2021 Mitsubishi ASX, ensuring that your CV joints and their boots are in top shape will keep your driveshaft and wheels spinning happily. Regular checks and timely maintenance at your local Mitsubishi service centre will help avoid unexpected repairs and keep the SUV running smoothly on Australian roads.
