Universal Joints on the 2015 Mitsubishi Outlander: What You Need to Know

When it comes to the 2015 Mitsubishi Outlander and its drivetrain components, the role of universal joints deserves a bit of attention. Universal joints, or U-joints as they're commonly called, are mechanical devices that allow for the transmission of power between two shafts that are not in a straight line. Their primary job is to accommodate the movement and angles between rotating shafts, usually in the driveline of vehicles. But are they actually used on the 2015 Mitsubishi Outlander? After referencing technical manuals and service literature for this model, it turns out that universal joints, in the traditional sense seen on some four-wheel drive vehicles, aren't really a part of the Outlander's setup.

The 2015 Mitsubishi Outlander features a more modern drivetrain, which relies on constant velocity (CV) joints rather than universal joints. CV joints are specifically designed to handle the front-wheel-drive layout that characterises the base setups on these vehicles, as well as the all-wheel-drive versions. Unlike universal joints, CV joints provide smooth power transfer while allowing for greater angles of articulation and are less prone to vibration issues when turning or going over bumps. This means Mitsubishi opted for CV joints over U-joints for better efficiency, smoother operation, and reduced maintenance in the Outlander's front and all-wheel-drive system.

So why are universal joints not used on the 2015 Mitsubishi Outlander? It essentially comes down to design and function. Universal joints are typically found on rear-wheel-drive vehicles or solid rear axles where the driveshaft needs to accommodate some angle changes between the transmission and the rear differential. The Outlander, however, uses a transaxle setup with half-shafts running from the transaxle directly to the wheels on the front axle. Since the angles involved in the front half-shafts demand consistent velocity and smooth operation, CV joints are the preferred technology here.

Another important reason universal joints aren't on the Outlander dated from 2015 is because U-joints tend to have a limitation on the angle they can handle without causing speed fluctuations and vibrations. CV joints were developed to overcome that limitation, delivering constant velocity despite the angles and suspension movements. Given the Outlander's focus on comfort and smooth driving, CV joints fit the bill much better and have become the industry standard in vehicles with front and all-wheel drive layouts.

In many older or traditional four-wheel-drive vehicles and trucks, universal joints can be found in the drive shafts where they connect the transfer case to front and rear axles. But the Outlander's drivetrain is designed differently. The front axle shafts are independent of the rear with electronically controlled all-wheel drive systems, depending on the model variant, reducing the need for conventional U-joints in driveline components.

While universal joints themselves are not used in the 2015 Mitsubishi Outlander, it is still helpful to understand their function and how maintenance typically works for those who own vehicles equipped with them. In general, universal joints allow power transfer at variable angles and play a crucial role in preventing drivetrain binding or damage. They connect pieces of the driveshaft, accommodating suspension movement and chassis flex. If universal joints fail, vibrations, clunking noises, and drivetrain damage can occur.

For vehicles fitted with universal joints, regular inspection and servicing can save the component from premature failure. Lubrication is key. Many U-joints come with grease fittings, and part of routine servicing involves greasing the joints to avoid wear and corrosion. Over time, bearings inside the joint can wear down, causing looseness or "play," which can be felt as vibrations or knocking during acceleration or deceleration.

Replacing universal joints involves removing the driveshaft, carefully extracting the worn joint, and installing a new one, often with specialised tools to press the bearing caps in place. If one universal joint in a driveshaft assembly has worn out, many mechanics recommend replacing all joints and even the centre bearing as a preventative step, ensuring even wear and smooth operation.

So even though the 2015 Mitsubishi Outlander does not actually have universal joints, maintaining the joints it does utilise, which are CV joints, is just as critical. CV joints also require periodic inspection and maintenance to prevent joint boots from cracking and letting grease escape or contaminants in. When properly cared for, these joints keep the Outlander's driveline running smoothly for many kilometres.

For Outlander owners keen to keep their vehicle in top shape, the takeaway is to focus on the condition of your CV boots and driveline components during servicing. Listen for clicking noises when turning, watch for grease leaks, and get any damaged parts replaced promptly. Although universal joints are not a part of the 2015 Outlander, understanding their role helps paint a clearer picture of driveline technology and the ongoing importance of proper maintenance for any vehicle's drivetrain.
