Parts for your 2016 Subaru Exiga-Universal joints

The Role and Maintenance of Universal Joints in the 2016 Subaru Exiga

When it comes to the 2016 Subaru Exiga, understanding its drivetrain components is key to figuring out whether universal joints play a role in this vehicle. The Exiga is a multi-purpose vehicle designed primarily for practicality and passenger comfort, with Subaru's well-known all-wheel-drive system forming an essential part of its drivetrain.

After consulting Subaru technical references and trusted automotive sources, it becomes clear that traditional universal joints, often found in rear-wheel-drive or certain all-wheel-drive vehicles, are not part of the standard drivetrain setup for the 2016 Exiga. Instead, this model employs a constant velocity (CV) joint system within its front-wheel drive and all-wheel-drive axles.

Why are universal joints not used? The answer lies in the specific drivetrain architecture of the 2016 Exiga. Universal joints are typically used in vehicles where the drive shafts need to handle significant angles between the transmission and the wheels, especially in setups involving solid rear axles or long driveshafts. They allow the drivetrain to transmit torque and rotation through varying angles without binding.

The Subaru Exiga's drivetrain makes use of transaxles and half-shafts with CV joints, which are more suited to front and all-wheel-drive vehicles with independent suspension setups. CV joints are particularly advantageous for front-wheel drive cars because they maintain constant rotational speed without vibration at various steering angles, something universal joints cannot achieve as smoothly. In the Exiga, the lightweight design and efficiency gains from CV joints contribute to better handling, ride comfort, and reduced mechanical noise.

Since universal joints are not fitted on the 2016 Subaru Exiga, there is no maintenance or replacement specific to those parts. Instead, this vehicle requires attention to its CV joints and associated components if any drivetrain service is needed. For owners, the takeaway is to focus on the proper inspection and maintenance of CV joints, driveshaft boots, and all-wheel-drive system components rather than hunting for universal joint issues.

That said, for those curious about universal joints and their role in vehicle drivetrains, here's a bit of an overview to help understand why some cars have them and how they function.

A universal joint, often nicknamed a "U-joint," is a mechanical device that connects two rotating shafts at angles to one another. Its main job is to transmit rotational power in situations where alignment between shafts is not perfectly linear. This is common in older rear-wheel-drive vehicles or in four-wheel-drive models where the driveshaft must accommodate suspension movement and chassis articulation.

Universal joints allow for smooth power transfer despite changes in the angle, preventing drivetrain binding and damage. Without them, the gearbox and wheels could force components to twist or snap during operation - especially over rough terrain or uneven road surfaces.

When universal joints are fitted, they deserve regular inspection during servicing. Over time, U-joints can wear out due to lack of lubrication, dirt contamination, or simply the stress of constant movement. Signs that a universal joint is failing include clunking noises when shifting gears, vibrations during acceleration, or even vibrations while driving at steady speeds.

Routine maintenance typically involves greasing the joints at scheduled intervals, which helps prolong their lifespan. Some universal joints come sealed and require no additional lubrication, but many are designed with grease fittings for easy servicing. Catching issues early, such as any looseness or roughness in the joint, can prevent costly drivetrain failures or breakdowns.

Should replacement be necessary, it is usually a straightforward job for a qualified mechanic. The worn-out joint is removed and replaced with a new part that matches the drivetrain specifications of the vehicle. Choosing quality replacement components and ensuring proper installation is crucial to maintaining drivetrain smoothness and integrity.

For people who own vehicles fitted with universal joints, integrating their inspection and lubrication into regular services is a simple way to keep the car running reliably. However, since the 2016 Subaru Exiga does not use universal joints but rather CV joints, owners should focus more on inspecting the condition of the rubber boots covering the CV joints. Damaged or cracked boots allow grease to escape and contaminants to enter, which can eventually lead to joint failure.

Getting into the habit of checking for grease leaks or unusual noises from the drivetrain can save money and hassle down the track. Early detection of CV joint problems means owners can replace the boot or the joint before it causes serious drivability issues.
