Parts for your 2016 Nissan Serena-Universal joints

Understanding Universal Joints on the 2016 Nissan Serena

When diving into the mechanics of the 2016 Nissan Serena, it's helpful to understand which parts are involved in its drivetrain and which are not. Universal joints, commonly known as U-joints, are a vital component in many vehicles, especially those with rear-wheel drive or four-wheel drive setups. However, the 2016 Nissan Serena typically comes with a front-wheel drive configuration, and this changes the need for universal joints in its design.

Universal joints are used to transfer rotary motion where the input and output shafts are not in a straight line. In vehicles with rear-wheel drive, U-joints are found on the driveshaft, allowing it to flex as the suspension moves up and down and the wheels turn. Since the driveshaft in these vehicles runs from the engine and transmission at the front to the rear differential, the universal joint ensures smooth power transfer despite changes in angle.

On the other hand, the 2016 Nissan Serena predominantly uses a transversely mounted engine with a front-wheel drive system. This layout means the power travels from the engine to the front wheels via constant velocity joints (CV joints) housed in the drive axles. CV joints perform a similar role to universal joints but are designed for consistent velocity and angular variance, providing smooth and efficient power transfer to the front wheels at various turning angles and suspension movements.

Because of this front-wheel drive setup, the Nissan Serena does not utilise the traditional universal joints found on rear-wheel drive or four-wheel drive vehicles. Instead, it relies on CV joints which are more suitable for front-wheel drive vehicles like the Serena.

If for some reason, such as a specialty or aftermarket modification, a 2016 Nissan Serena were to have universal joints installed, understanding their purpose and maintenance is useful. Universal joints themselves are designed to allow the driveshaft to flex and accommodate suspension movement or changes in drivetrain alignment. They consist of a cross-shaped centre bearing with needle bearings housed in caps that allow the shaft ends to rotate and pivot relative to each other.

Maintaining universal joints is crucial for the health of any drivetrain. Over time, these joints wear out due to friction and lack of lubrication. Neglecting them can lead to vibration, clunking noises, and eventual failure which could leave the vehicle unable to move. Regular servicing involves inspecting for play or looseness, rust, contaminants, and ensuring they are properly lubricated if grease fittings are present.

When replacing universal joints, it is important to select the correct type and size for the vehicle, to prevent premature wear or driveline issues. The replacement process typically involves removing the driveshaft, pressing out the old U-joints, and fitting new ones before reassembling and balancing the driveshaft.

Though the 2016 Nissan Serena does not come fitted with universal joints, understanding their role helps in appreciating why CV joints are the go-to for front-wheel drive vehicles. CV joints offer smoother operation and more flexibility for the steering movement and suspension travel seen in cars like the Serena.
