Parts for your 2010 Nissan Serena-Universal joints

Universal Joints and the 2010 Nissan Serena

When chatting about the 2010 Nissan Serena and its drivetrain, the question of universal joints often pops up. Universal joints, commonly known as U-joints, are mechanical components that allow a drive shaft to transmit power through varying angles. However, for the 2010 Nissan Serena, universal joints aren't a part of the equation.

That is mainly down to the type of driveline system the Serena uses. This vehicle comes with a front-wheel-drive layout and options for an all-wheel-drive system using constant velocity (CV) joints instead of traditional universal joints. CV joints are very effective for front-wheel-drive vehicles or ones that require smoother power delivery through complex steering movements, which is exactly the case with the Serena.

Universal joints are typical in rear-wheel-drive or four-wheel-drive vehicles with solid drive shafts running between the gearbox and the rear axle. These U-joints handle the angles created by suspension movement and axle articulation. In contrast, the Nissan Serena's powertrain is designed around CV joints on its front axles, providing flexibility for the steering and suspension without the need for U-joints.

So why are U-joints not used in the 2010 Serena? The main reason comes down to the advantages CV joints offer for this style of vehicle. CV joints maintain constant rotational speed without the vibrations or speed fluctuations associated with universal joints. Since the Serena often functions as a family people mover that prioritises smooth driving and comfort, CV joints help keep the ride quiet and vibration-free.

To break it down, CV joints are generally preferred in front-wheel and all-wheel-drive cars because they:

• Allow for smoother power transfer while steering
• Can handle greater angles with less vibration
• Offer better reliability for the constant movement of front wheels

Given the design priorities of the Nissan Serena, universal joints are simply not a relevant or necessary part of the drivetrain.

That said, while there might not be U-joints to worry about, the Serena's CV joints do require some maintenance and occasional inspection to keep things running smoothly. The protective rubber boots surrounding CV joints can crack or tear over time, letting in dirt and grease loss, which might lead to joint wear or failure.

For anyone servicing their 2010 Nissan Serena, it's smart to have the CV boots checked at regular intervals. If any damage is spotted, replacement boots or joint servicing should be organised promptly to avoid expensive repairs down the track. Unlike universal joints, which often just need greasing, CV joints require the boot to be intact to keep their lubricated environment effective.

In terms of replacement, when a CV joint does fail in the Serena, it often presents as clicking noises during turns, vibration through the steering wheel, or even difficulty turning smoothly. Fixing a bad CV joint generally involves swapping the entire axle shaft assembly, which includes the CV joints at either end prepacked with grease and sealed for long-lasting performance.

Regular servicing schedules recommend a thorough inspection of the drivetrain components every 20,000 to 30,000 kilometres, checking boots and joints for damage or wear. Keeping an eye on these components supports the long-term reliability of the Serena's drive system.

So, while universal joints play a critical role in many vehicle types, the 2010 Nissan Serena does not feature them due to its specific front-wheel- and all-wheel-drive setup utilising CV joints. The focus should be on maintaining those CV joints for a smooth and trouble-free drive experience.
