Universal Joints on the 2016 Nissan Pathfinder: What You Need to Know

When it comes to the drivetrain components of the 2016 Nissan Pathfinder, universal joints, often called U-joints, are not typically part of the design. This might come as a surprise since U-joints are a common feature in many four-wheel drive and rear-wheel drive vehicles. However, the 2016 Pathfinder largely relies on CV joints, or constant velocity joints, instead. Let's take a look at why this is the case and what it means for owners of this popular SUV.

The 2016 Nissan Pathfinder is a front-engine, front-wheel drive vehicle with the option for all-wheel drive. In vehicles like this, power is usually delivered to the wheels using half shafts that are fitted with CV joints rather than universal joints. CV joints are designed to allow smooth transfer of torque through variable angles with minimal friction, which is important for front-wheel drive and all-wheel drive vehicles where the suspension and steering movement affect the axle angles significantly.

Universal joints are more common in vehicles with a solid rear axle or in older drivetrain designs, especially where the driveshaft needs to transmit power over a long distance between the transmission and differential with variable angles. They allow the driveshaft to flex and rotate even when there is misalignment between the components. However, they can be a bit less smooth in operation compared to CV joints and usually require periodic maintenance or replacement.

The 2016 Nissan Pathfinder's modern drivetrain design utilises a front transaxle combined with half shafts that incorporate CV joints. This set-up not only allows for better handling and smoother operation but also reduces the need for the type of universal joints found in traditional rear-wheel drive or four-wheel drive drivetrains. Since the power delivery is more compact and operates within a narrower range of motion, CV joints can handle the job effectively without the drawbacks that universal joints might introduce.

For Nissan Pathfinder owners, this means universal joints generally do not need to be part of regular servicing or replacement routines. Instead, attention should be focused more on checking the CV joints, especially the rubber boots that protect them from dirt and moisture. If these boots crack or tear, the CV joint inside can quickly degrade, leading to clicking noises when turning or even loss of drive.

That said, if the Pathfinder you're looking at happens to be a variant with a traditional driveshaft and universal joints - although rare for this model year - it is important to know what universal joints do and how to maintain them. U-joints are critical components that allow the driveshaft to flex and articulate when the suspension moves over bumps or uneven ground. They help keep the power flow consistent to the rear wheels without binding or causing vibrations.

Over time, universal joints can wear out due to normal use, exposure to dirt, and loss of lubrication. If a U-joint starts to fail, drivers might notice clunking sounds when shifting from reverse to drive, vibrations at higher speeds, or even difficulty maintaining smooth power delivery. Because universal joints are rigorously tested components, many are sealed and maintenance-free these days, but older or aftermarket replacements might require regular greasing and inspection.

Should a universal joint require replacement, it is crucial to address the job promptly. A failing U-joint can lead to driveshaft failure and potentially cause serious damage to the underside of the vehicle or even create a safety hazard while driving. Replacement usually involves removing the driveshaft, pressing out the worn U-joint, and fitting a new one with precision to ensure smooth operation.

Fortunately, for most 2016 Nissan Pathfinder models equipped with CV joint-driven axles, universal joint issues are quite rare and not something drivers typically need to worry about. Instead, regular inspection of the CV joint boots and listening for unusual noises when turning can help keep the drivetrain in top shape. Modern Nissan engineering aims to provide a smooth, low-maintenance driving experience where universal joints are simply not part of the picture.

In the end, the absence of universal joints in the 2016 Nissan Pathfinder highlights the vehicle's focus on modern drivetrain technology and efficiency. The CV joints used are well-suited for the vehicle's configuration and driving dynamics, requiring less frequent servicing and likely avoiding the common issues seen with U-joints in tougher mechanical setups.

If you own a 2016 Nissan Pathfinder or are looking to buy one, it is always a good idea to keep up with scheduled maintenance, check the condition of suspension and drivetrain components, and seek out professional advice if you notice any unusual driving symptoms. Whether it's understanding the role of universal joints or ensuring the CV joints stay healthy, staying informed contributes to a longer lifespan and better performance for your vehicle.
