Universal Joints on the 2020 Nissan Serena: What You Need to Know

When it comes to the 2020 Nissan Serena and universal joints, it's important to understand the role these components play and whether they are actually part of this vehicle's drivetrain. The Nissan Serena is a popular multi-purpose vehicle (MPV) primarily designed for urban and family use, and its drivetrain configuration is quite straightforward compared to off-road or heavy-duty vehicles where universal joints are more commonly found.

For those unfamiliar, universal joints, often called U-joints, are flexible couplings used in the drivetrain to transmit rotary motion between two shafts that are at an angle to each other. They are especially vital in vehicles where the drive shafts need to move up and down with the suspension while still delivering power smoothly from the engine to the wheels. U-joints absorb the changes in angle and reduce stress on the drivetrain components.

Now, for the 2020 Nissan Serena, the situation is a bit different. This vehicle typically comes with either a front-wheel-drive or an all-wheel-drive setup. In front-wheel-drive cars, the power goes from the engine through a transaxle directly to the front wheels via constant velocity (CV) joints. CV joints are different from universal joints and are designed to accommodate the steering and suspension movement in a way that provides smoother, more consistent power delivery than U-joints would in this context.

For the all-wheel-drive versions of the Serena, power is delivered to the rear wheels via a prop shaft. However, the design of the drive system for this vehicle generally incorporates constant velocity joints rather than traditional universal joints. CV joints are preferred in front or all-wheel-drive vehicles because they operate efficiently at higher angles and maintain consistent rotational speed, which reduces vibrations and wear.

So why are universal joints not used in the 2020 Nissan Serena? The answer lies in the vehicle's design and intended use. U-joints are excellent for vehicles with solid rear axles, like trucks or older rear-wheel-drive cars, where the drive shaft needs to accommodate changes in angle between the transmission and the rear axle during suspension travel. The Serena's drivetrain setup doesn't require these sorts of movements. Instead, the use of CV joints enhances performance, reliability and overall comfort for everyday driving.

This means if you're checking out a 2020 Nissan Serena, you won't find universal joints as part of the drivetrain system. Instead, maintenance focuses more on components like CV joints, drive shafts and boots to keep the power delivery smooth and noise-free. Replacing or servicing CV joints typically involves inspecting the protective rubber boots for cracks or tears. Damaged boots allow dirt and moisture in, causing joint wear and eventual failure. Owners should look out for clicking sounds during sharp turns or vibrations at higher speeds, which can be signs of failing CV joints.

In contrast to universal joints, CV joints do not usually need frequent greasing or lubrication since they are packed with grease and sealed inside the boot. Regular inspections remain key to catching any issues early and avoiding expensive repairs down the line.

While universal joints are a critical part of many vehicles' drivetrains, especially in rear-wheel-drive or 4WD trucks, they are not relevant to the 2020 Nissan Serena's engineering. The focus instead is on CV joints and keeping these well-maintained to ensure the vehicle runs smoothly for all those family outings and daily school runs.
