Parts for your 2019 Mitsubishi Asx-Universal joints

Understanding Universal Joints on the 2019 Mitsubishi ASX

When it comes to the drivetrain and suspension components of the 2019 Mitsubishi ASX, the question often arises: does this vehicle use universal joints, or U-joints? After consulting technical sources and reviewing the ASX's drivetrain layout, it turns out that universal joints as traditionally known are not fitted to the standard 2019 Mitsubishi ASX models. Instead, the vehicle primarily uses constant velocity joints, commonly known as CV joints, which serve a similar but not identical purpose.

The universal joint is a type of coupling in a driveline that allows the drive shaft to transmit power while accommodating changes in angle between components. U-joints are found in many rear-wheel and four-wheel drive vehicles, particularly those with solid rear axles or older drivetrain designs. They allow torque to be delivered around bends and over irregular chassis layouts while compensating for movement in the suspension.

In the case of the 2019 Mitsubishi ASX, which features a front-wheel-drive platform (with some variants offering all-wheel drive via an active centre differential), the drivetrain setup uses CV joints at the front axles. These joints are specially designed to maintain a constant rotational speed regardless of steering angle or suspension movement, making the use of universal joints unnecessary. CV joints are better suited to front-wheel drive vehicles due to their ability to handle the sharp angles encountered during steering, providing smooth power delivery without vibrations.

Why does the ASX avoid universal joints? It largely comes down to the layout of the drivetrain and the vehicle's engineering. The ASX's powertrain demands joints that can handle tight steering angles efficiently, and CV joints are purpose-built for this. Universal joints tend to be used in driveline shafts that transmit power over longer distances across multiple angles but are less effective at maintaining smooth motion under tight angles and high steering loads that front axles experience. Therefore, in a typical front-wheel-drive or all-wheel-drive crossover SUV like the Mitsubishi ASX, CV joints replace universal joints entirely.

For those who own a 2019 Mitsubishi ASX and are curious about the maintenance and servicing of these important drivetrain components, focusing on CV joints is the way to go. CV joints consist of a flexible boot, filled with grease, protecting the joint and allowing it to move freely without contamination. If this boot tears or fails, dirt and moisture can enter, leading to joint wear or failure. Symptoms of CV joint issues include clicking noises during turns or vibrations under acceleration.

Regular inspection of the CV boots should be part of standard servicing. Catching boot tears early can save major repair bills down the track. Replacing damaged boots or the CV joint itself if worn ensures the ASX maintains smooth handling and avoids driveline complications. Typically, CV joints last well beyond 100,000 kilometres if the boots remain in good condition, but neglect can shorten their life significantly.

Unlike universal joints, which may require greasing during servicing, CV joints are usually sealed and pre-packed with grease. This makes maintenance easier but also means any damage to the protective boot demands swift attention. Front-wheel-drive vehicles like the ASX rarely face the more intensive maintenance demands common to U-joints found on heavy-duty 4WDs or older rear-wheel-drive cars.

For diligent car owners, keeping an eye out for any grease splattered around the inside of the wheel well is a good indication of a compromised CV boot. Additionally, listening for unusual noises or feeling vibrations through acceleration can signal joint wear that might need a professional mechanic's attention. Prompt replacement of worn components preserves the smooth and reliable performance that Mitsubishi ASX owners expect.

Ultimately, the design choices on the 2019 Mitsubishi ASX emphasise advanced CV joint technology over traditional universal joints. The result is a drivetrain well-optimised for the vehicle's size, weight, and typical on-road use. Whether cruising around town or heading out on a weekend adventure, the ASX delivers dependable power transfer without the need for universal joints, offering a fuss-free ownership experience.
