Universal Joints on the 2016 Nissan Navara: What They Do and How to Look After Them

The 2016 Nissan Navara is a rugged, reliable ute designed for both work and play across Australia's diverse terrain. One key component that plays a vital role in the driveline of this vehicle is the universal joint, often called the U-joint. These parts might not be the first thing that comes to mind when thinking about vehicle maintenance, but they are crucial for smooth power delivery from the engine to the wheels.

Universal joints are typically found in the driveshaft of rear-wheel drive and four-wheel drive vehicles like the Navara, which transfers engine power to the rear axle. The driveshaft needs to accommodate the movement of the suspension and the relative motion between the transmission and the axle. This is where universal joints come into play: they allow for the driveshaft to flex while still transmitting power efficiently, even when the angles between the transmission and axle change as the vehicle moves.

For the 2016 Nissan Navara, universal joints are very much part of the driveline setup, especially given that many Navaras come with rear-wheel drive or four-wheel drive configurations. The driveshaft will have universal joints at either end, connecting it to the transmission at the front and the differential at the rear. This setup helps manage the up and down movements of the suspension while ensuring constant rotation and torque transfer to the wheels.

One of the main reasons universal joints are vital for the Navara is because it frequently encounters off-road conditions and varied surfaces. When the rear axle moves over uneven ground, the angle between the transmission output shaft and the differential input shaft constantly changes. Without universal joints, the driveshaft would be rigid, leading to binding, vibrations, and potential driveline failure. The universal joints are designed to flex and accommodate these movements safely.

Over time, like any mechanical component, universal joints on the Navara can wear out or become damaged. This wear is often due to constant flexing, exposure to water and dirt, and lack of lubrication. Regular servicing of universal joints helps maintain the Navara's driveline performance and can prevent more costly repairs down the track.

When it comes to servicing the universal joints on a 2016 Nissan Navara, mechanics usually check for signs of play or looseness in the joints. Excessive play can cause vibrations, clunking noises, or a noticeable shudder when accelerating or decelerating. These symptoms indicate the U-joints may be nearing the end of their service life.

One maintenance tip for universal joints is lubrication. Some Navara models are equipped with greasable universal joints, allowing mechanics to apply fresh grease using a grease gun during scheduled services. This helps keep the bearings inside the joint properly lubricated, reduces wear, and extends the lifespan of the joint. However, many modern U-joints come sealed and do not require greasing, so it's essential to check the vehicle's manual or consult a trusted mechanic.

If the universal joints on the Navara are non-greasable or have been exposed to harsh off-road conditions, it's especially important to inspect them regularly. Driving in muddy, wet, or salty environments, common in many parts of Australia, can accelerate wear and corrosion on universal joints. Regular washes and underbody inspections will help keep the parts in good shape.

Replacement of universal joints on a Navara isn't typically a DIY job for most owners, as it involves removing the driveshaft from the vehicle and carefully disassembling the joints. It's best left to skilled technicians with the right tools and components. During replacement, it is advisable to also inspect the driveshaft's centre bearing and slip yoke, as these parts work together and may show signs of wear if the U-joints are worn out.

Choosing quality replacement parts is also essential for maintaining your Navara's driveline reliability. OEM or equivalent universal joints designed specifically for Nissan's specifications will ensure proper fit and durability. Installing lower-quality components could lead to premature wear and even damage other parts of the driveline.

In practise, keeping an eye on the condition of the universal joints extends more than just their lifespan. It helps maintain the overall drivability and comfort of the Navara, reduces noise and vibrations, and ensures safe and predictable handling. After all, a worn-out U-joint could lock up or fail unexpectedly, leading to a loss of vehicle control or further mechanical damage.

So, for owners of a 2016 Nissan Navara, including universal joint inspection and servicing as part of routine vehicle care is a smart move. Whether you use your Navara for towing, off-roading, or everyday driving, these small but crucial components make sure power gets where it's needed without hiccups. A bit of attention to the universal joints will keep the Navara going strong and ready for whatever the Australian outdoors throws at it.
