Understanding Universal Joints on the 2018 Mitsubishi Eclipse Cross

The 2018 Mitsubishi Eclipse Cross is a popular compact SUV known for its stylish design and solid performance. When it comes to drivetrain components like universal joints, it's important to understand whether this SUV actually uses them and what role they play if fitted. After referencing various technical manuals and manufacturer specifications, it turns out the 2018 Mitsubishi Eclipse Cross does not typically use universal joints in its drivetrain system.

Universal joints, often called U-joints, are common in many vehicles with traditional rear-wheel-drive or four-wheel-drive layouts where the driveshaft needs to transfer torque through varying angles. They allow the driveshaft to flex and accommodate movements from the suspension and steering, especially in vehicles with solid rear axles or older four-wheel-drive designs. However, the Eclipse Cross mainly features a front-wheel-drive setup with an optional all-wheel-drive system that uses different drivetrain components.

Because the Eclipse Cross uses a transversely mounted engine and a compact all-wheel-drive system that distributes torque electronically rather than mechanically through a long driveshaft, universal joints aren't necessary in this vehicle's layout. Instead, Mitsubishi employs constant velocity (CV) joints on the front axles and rear axles (if AWD is fitted), which are designed to handle the angular movement of the wheels more smoothly and efficiently. CV joints provide a constant rotational speed without the vibrations that can be produced by universal joints, making them more suitable for the compact, front-wheel-based drivetrain design of the Eclipse Cross.

This difference is significant because universal joints generally appear in vehicles with longitudinally mounted engines and a separate driveshaft sending power to the rear wheels. The Eclipse Cross's design prioritises space efficiency, smooth operation, and lower maintenance, which CV joints support better than universal joints. That is why universal joints are not part of the 2018 Mitsubishi Eclipse Cross's drivetrain setup.

Even though universal joints are not fitted, understanding their role in other vehicles is still helpful, especially for those who may own different types of cars or are curious about drivetrain technology.

Universal joints are essentially flexible couplings located in the driveshaft that transmit rotary power between shafts that are not in a straight line. As the vehicle moves over bumps or turns, these joints handle the changes in angle between the transmission and the axle or differential. Without them, the drivetrain would struggle with binding or even failure due to constant misalignment as the suspension moves.

In vehicles that have universal joints, proper maintenance is vital. Over time, U-joints endure wear and tear, particularly in off-road or heavy-duty use. Signs that a universal joint may need maintenance or replacement include:

• Vibrations or shuddering at certain speeds
• Clunking or popping noises when shifting or accelerating
• Visible rust or corrosion on the U-joint itself
• Excessive play or looseness in the driveshaft

Servicing universal joints typically involves lubrication where possible. Some universal joints come with grease fittings allowing regular greasing to prolong their life. However, many modern U-joints are sealed and designed to be maintenance-free, meaning they only get replaced when worn out.

During routine vehicle servicing, technicians generally inspect the driveshaft and U-joints for signs of wear. Early detection can prevent more severe drivetrain damage and costly repairs. Replacing a worn universal joint on older or traditional 4WD vehicles usually requires removing the driveshaft and swapping out the U-joint, which must be done carefully to maintain balance.

For 2018 Mitsubishi Eclipse Cross owners, attention should be paid more to the condition of CV joints rather than universal joints. CV joints require their own maintenance, especially checking the CV boots for cracks or tears that can allow grease to escape and dirt to enter, leading to premature joint failure.

In a nutshell, while universal joints play a critical role in many vehicles with longitudinal drivetrain layouts, the 2018 Mitsubishi Eclipse Cross's AWD and FWD systems utilise CV joints exclusively. This design choice reflects modern engineering focused on smoother operation, less maintenance, and improved reliability for everyday driving in Australia's varied conditions.
