Parts for your 2017 Nissan Navara-Universal joints

Understanding Universal Joints on the 2017 Nissan Navara

The 2017 Nissan Navara is a robust ute designed to handle tough conditions and deliver reliable performance both on and off the road. When it comes to the driveline components, universal joints play an essential role in many 4WD and rear-wheel-drive vehicles, helping transfer rotational power smoothly between components that are at different angles. But are universal joints actually relevant to the 2017 Nissan Navara? The short answer is yes, they definitely are part of the vehicle's drivetrain system.

Universal joints, often called U-joints, are used in the Navara to connect the drive shaft to the transmission and the rear differential. They allow for the necessary flexibility as the suspension moves and as the chassis flexes during driving. Because the Navara utilises a live rear axle setup with a driveshaft running from the gearbox to the rear differential, universal joints are crucial in keeping power flowing smoothly, despite the angle changes between these components.

In the 2017 Nissan Navara, you will find U-joints located at either end of the driveshaft. These small but tough components are designed to rotate freely and handle the movement that occurs when the vehicle drives over rough or uneven terrain. Without universal joints, driveshafts would be rigid and unable to accommodate suspension travel, which could lead to drivetrain damage or severe vibrations.

They are fundamental for maintaining drivetrain integrity, so it's important to understand how universal joints work and what maintenance or replacement steps are needed to keep them in top shape.

Universal joints consist of a cross-shaped centre piece called the spider, which sits inside a pair of yokes. Each arm of the spider connects to a bearing cap that allows the joint to pivot smoothly. This design enables the driveshaft to transmit power even when it isn't perfectly straight, which is exactly how it needs to function on a Navara where suspension articulation means constant slight angle adjustments at the U-joints.

Over time and with hard use, especially in off-road or towing situations which the Navara is well known for, U-joints can wear out. The bearings inside the caps might dry out or become contaminated by dirt and moisture, leading to rust and increased friction. This wear commonly manifests as a clunking noise when accelerating or decelerating, vibrations through the vehicle at higher speeds, or even visible play in the driveshaft if you check it by hand.

Fortunately, universal joints are fairly easy to service or replace if you know what to look for. Regular inspections should be part of servicing your 2017 Nissan Navara. This involves checking for excessive play in the driveshaft, listening for unusual noises, and looking out for signs of rust or grease leaks around the joint.

Many U-joints, especially in vehicles like the Navara, come with grease fittings that allow for regular lubrication, which significantly extends their life. Greasing your universal joints during routine servicing can prevent premature failure by keeping the bearings well lubricated and free from contaminants.

If the U-joints have gone too far and replacement is necessary, it's a job that is best handled with some mechanical know-how or by a professional. Removing the driveshaft and pressing out the old U-joints can be a bit fiddly because these parts need to fit precisely. Using the correct replacement parts designed for the Navara ensures smooth operation and avoids issues down the track.

Ignoring worn universal joints can lead to bigger problems, like damage to the driveshaft, rear differential or transmission output flange. So keeping an eye on the condition of these components not only protects your Navara but also contributes to overall driving comfort and safety.

In terms of routine maintenance, it's wise to have the universal joints checked during regular service intervals or if you notice any of the warning signs mentioned. Off-road enthusiasts and those who tow heavy loads should pay special attention as their vehicles' U-joints typically experience more stress.

In short, universal joints are a key part of the drivetrain on the 2017 Nissan Navara and play an indispensable role in transferring engine power to the rear wheels while absorbing changes in angle caused by movement of the suspension and drivetrain. Proper servicing, regular greasing, and timely replacement help keep the Navara performing well no matter where the road or trail takes it.
