Understanding Universal Joints and Their Role in the 2018 Mitsubishi ASX

The 2018 Mitsubishi ASX is a popular compact SUV that balances practicality with efficient design, particularly in its drivetrain layout. When it comes to universal joints, commonly known as U-joints, it's important to first clarify whether this component is actually part of the ASX's mechanical setup before diving into what these parts do and how they're maintained.

In the case of the 2018 Mitsubishi ASX, universal joints as standalone components are not typically found or relevant. This is largely due to the particular type of drivetrain used in this vehicle. The ASX generally employs a front-wheel drive system or an all-wheel drive system that utilises constant velocity (CV) joints instead of traditional universal joints. CV joints perform a similar function but are designed specifically for front-wheel drive and independent suspension systems, offering smoother power delivery over the wide range of motion experienced at the front wheels.

So why doesn't the 2018 Mitsubishi ASX use universal joints? It mainly comes down to design and efficiency. U-joints are more commonly seen in vehicles with solid rear axles or rear-wheel drive layouts, where they connect the driveshaft to the transmission and the differential, allowing the driveshaft to flex with the movement of the suspension and prop shaft angles. These joints handle significant angular movement but typically don't provide the constant rotational velocity needed in front-wheel drive suspensions.

In contrast, CV joints are engineered to maintain rotational speed without fluctuations despite the up-and-down and side-to-side motions of the wheels. This makes them ideal for the independent front suspension and front-wheel drive system of the ASX. Essentially, the CV joint is a specialised type of universal joint that offers more consistent performance and less vibration, which enhances driving comfort and component longevity.

Even on the all-wheel drive versions of the 2018 Mitsubishi ASX, the design still favours CV joints. The complex front and rear axle shafts require reliable joints that can handle tight turning angles and suspension travel without causing drivetrain vibration or premature wear. The CV joint is the perfect fit for this application, making traditional universal joints unnecessary and irrelevant.

For owners of the 2018 Mitsubishi ASX, understanding this difference is helpful when considering servicing and maintenance. While universal joints are not part of the drivetrain, the CV joints are crucial components that need attention to keep the vehicle performing at its best. CV joints are usually protected by rubber boots that keep grease in and dirt out, and these boots are the first items to inspect during routine servicing.

Anyone maintaining an ASX should be mindful of chipped or torn CV boots, as damage here can lead to grease leakage and contamination, causing the joint to wear out prematurely. Symptoms of a failing CV joint include clicking sounds when turning, vibrations while driving, or even noticeable grease splatter around the wheel wells. If these signs appear, it's wise to get the CV joints checked and potentially replaced by a qualified mechanic.

Regular servicing of the 2018 Mitsubishi ASX often involves inspection rather than direct universal joint maintenance, given the absence of such parts. Mechanics will typically examine the CV boots for tears or leaks and ensure the joints themselves are functioning smoothly. Early detection of any issues can prevent costly repairs and maintain the smooth handling characteristics the ASX is known for.

Replacement of CV joints, when necessary, should be done promptly to avoid further drivetrain damage. This usually involves removing the axle shaft and replacing the entire joint or the axle assembly, depending on the extent of wear. Many workshops recommend changing the CV boots or joints once signs of wear appear rather than waiting for complete failure.

In essence, while universal joints are an important drivetrain component in many traditional rear-wheel drive or four-wheel drive vehicles, they do not play a role in the 2018 Mitsubishi ASX's drivetrain. Instead, CV joints take on this critical function, providing durable and efficient power delivery to the wheels under all driving conditions. Keeping these joints in good condition through regular inspection and timely maintenance helps ensure that the ASX remains reliable, comfortable, and safe on the road.
