Driveshafts on the 2019 Nissan Serena: What You Need to Know

The 2019 Nissan Serena is a popular multi-purpose vehicle known for its spacious interior and family-friendly features. When looking into the drivetrain components of the Serena, it's important to understand whether driveshafts play a role in its operation and what their purpose would be if they do. After reviewing a variety of technical sources and vehicle specifications, it becomes clear that the 2019 Nissan Serena, particularly the models available in markets such as Australia, generally does not use traditional driveshafts in the way typical rear-wheel-drive vehicles do.

The reason behind this mainly comes down to the Serena's drivetrain layout. Most 2019 Nissan Serena models are front-wheel drive or come with an all-wheel-drive system that uses a different configuration compared to conventional rear-wheel-drive cars. In a front-wheel-drive vehicle like the Serena, power from the engine is delivered directly to the front wheels through a transaxle, which combines the transmission and differential into one compact unit. This design eliminates the need for a long driveshaft running from the front engine/transmission to the rear wheels.

For Serena models equipped with an all-wheel-drive system, the setup often uses an on-demand rear differential connected via a shorter prop shaft or half-shafts, rather than a traditional driveshaft running the length of the vehicle. These components are designed more to supplement traction when needed rather than continuously transfer power like in full-time four-wheel-drive systems.

So why does the Serena not use traditional driveshafts? It's simple - the front-wheel-drive design offers efficiency in terms of packaging, weight, and fuel economy. Without the need for a bulky driveshaft tunnel down the middle of the car, the interior space can be maximised, which is a big plus for a people mover. Additionally, the simpler front-wheel-drive setup generally means less maintenance and fewer mechanical parts that can wear out over time.

Now, if you still own a 2019 Nissan Serena or are considering one and are curious about drivetrain maintenance, it's helpful to know what parts you do need to keep an eye on. Rather than driveshafts, this vehicle's drivetrain servicing focuses more on components like constant velocity (CV) joints and axles that connect the transaxle to the front wheels. CV joints allow the wheels to turn and move up and down with the suspension while maintaining smooth power delivery. They have protective rubber boots which can crack or tear over time, letting dirt and moisture in and leading to joint wear. Regular inspection and replacement of worn CV boots is a key maintenance task.

For models with all-wheel-drive, owners should also be aware of the prop shaft or half-shafts that send power to the rear wheels occasionally. While these shafts are usually quite durable, they still benefit from periodic inspection during routine servicing to check for any play, unusual noises, or vibrations that could indicate wear or damage. Early detection means cheaper fixes and keeps the Serena running smoothly on the road.

When it comes to maintenance intervals, Nissan typically recommends inspecting CV boots and axles during scheduled services, which often happen around every 15,000 to 30,000 kilometres. If a torn boot is found, it's wise to replace it immediately along with cleaning the joint or replacing the CV axle entirely if there's significant damage or noise. Keeping these components in good nick helps avoid costly repairs down the track and ensures safe handling and stability.

One handy tip for Serena owners is to listen for clicking noises when turning sharply, as this is a classic sign of a worn or damaged CV joint. Regular servicing by a qualified mechanic will catch these issues early, saving you from unexpected breakdowns or a compromised driving experience. Also, keeping an eye on grease leaks around the wheels or abnormal vibrations during acceleration might indicate axle problems.

Because the Serena doesn't use a traditional long driveshaft, the typical problems associated with driveshafts like centre bearing wear or universal joint failure do not apply here. This means owners are spared some of the more complex driveshaft repairs common in rear-wheel-drive vehicles. Instead, their focus should be on proper care and inspection of the CV joints and related components to maintain performance and avoid disruptions.

All up, understanding the drivetrain of the 2019 Nissan Serena helps owners appreciate why traditional driveshafts aren't part of the picture and where to direct their maintenance efforts. The front-wheel-drive and on-demand all-wheel-drive systems use different components that require their own specific care. Simple inspections, timely replacements of boots and joints, and listening out for unusual noises are the best ways to keep the Serena's drivetrain in top shape for many happy kilometres ahead.
