Universal Joints and the 2017 Nissan Pulsar: What You Need to Know

When it comes to the 2017 Nissan Pulsar, one common question that pops up is whether or not this vehicle uses universal joints. To put it simply, the 2017 Nissan Pulsar does not employ universal joints in its drivetrain setup. This might surprise some folks, especially if they're familiar with older or more traditional vehicles that often rely on universal joints to connect shafts that transmit power at different angles.

Why is this the case? The answer lies in the car's design and drivetrain technology. The 2017 Nissan Pulsar is primarily front-wheel drive and uses a transaxle system, which is quite different from the drive shaft setups in rear-wheel drive cars or some all-wheel drive models that typically require universal joints. Cars with front-wheel drive usually have constant velocity (CV) joints instead of universal joints.

CV joints are designed to handle the power transmission to the front wheels while allowing for smooth rotation at various angles, especially because the front wheels also steer the car. These joints offer better durability and smoother performance at higher angles and speeds compared to traditional universal joints. So, the need for universal joints simply doesn't arise in the Pulsar's powertrain configuration.

To give a bit more background, universal joints are mechanical components found in many older cars and some modern ones with rear-wheel or four-wheel drive, where the driveshaft needs to transmit torque through an angle between the transmission and the differential. They allow the driveshaft to flex and move while still delivering power efficiently. This is important in vehicles where the rear wheels are driven and the engine is mounted at the front, creating an offset between the transmission and rear axle.

Since the Pulsar uses a transaxle combining transmission and differential on the front axle, and employs CV axles to connect to the wheels, the driveshafts themselves don't need to handle transmission at the same varying angles that require universal joints. Instead, CV joints take care of the angular movement at the wheels.

Now, if you're a 2017 Nissan Pulsar owner, you won't be dealing with universal joints as part of your vehicle's maintenance or servicing. Instead, your focus should be on the condition of the CV joints and their protective boots. As these joints and boots wear out or get damaged, you might notice clicking noises when turning or experience vibration during acceleration. These signs indicate the CV joints need attention, and it's critical to replace faulty parts promptly to prevent further damage and ensure your car's smooth handling.

While universal joints are not part of the Pulsar's setup, understanding their purpose can help you appreciate the different drivetrain configurations on other vehicles. Universal joints are essential components in many trucks, older cars, and some SUVs that have a separate driveshaft connecting the transmission and rear axle. They enable power to be transmitted even as the suspension moves up and down and the wheels turn, making for a flexible yet solid connection.

Routine inspection and maintenance of universal joints typically involve checking for signs of wear such as excessive play, rust, or vibrations. When universal joints deteriorate, they can cause driveline vibrations, clunking noises, or even failure leading to loss of power transmission to the wheels. Servicing universal joints usually means lubricating them regularly (if they come with grease fittings) or replacing them when they become worn or damaged.

For Nissan Pulsar owners, since CV joints replace the role of universal joints, keeping an eye on CV joint boots is crucial because damaged boots let grease leak out and dirt get in, rapidly wearing out the joints. Servicing would often include inspecting these boots during routine oil changes or tyre rotations, and replacing them if cracks or tears are found.

In essence, the 2017 Nissan Pulsar's design makes universal joints unnecessary, thanks to its front-wheel drive layout and use of CV joints. This not only simplifies the drivetrain but also enhances reliability and reduces maintenance hassles commonly associated with universal joints. While universal joints remain important for dozens of other vehicles on Australian roads, Pulsar owners can focus on ensuring their CV joints are in tip-top condition.
