Driveshafts on the 2018 Subaru Exiga: What You Need to Know

The 2018 Subaru Exiga is a versatile vehicle known for its spacious interior and reliable performance. When it comes to the drivetrain, many people wonder about the role of driveshafts and whether this particular vehicle uses them. After consulting various technical sources and Subaru's official documentation, it's clear that driveshafts are indeed a part of the 2018 Subaru Exiga's setup, especially in its all-wheel-drive system.

For those not familiar, driveshafts are components that connect the transmission and the wheels, transmitting power from the engine to the wheels to get the car moving. In the case of the Subaru Exiga, which features Subaru's well-known symmetrical all-wheel drive system, driveshafts play a crucial role in transferring torque to the rear wheels, providing power to all four wheels for better traction and stability.

Understanding the purpose and maintenance of driveshafts is essential for maintaining the performance and safety of the Subaru Exiga. Here is a detailed guide about the driveshafts in this vehicle and what to keep in mind for servicing and replacement.

The purpose of driveshafts in a vehicle like the Subaru Exiga extends beyond just transmitting power. Driveshafts need to accommodate the movement of the suspension and the steering while remaining strong enough to handle the engine's torque. In a car with all-wheel drive, such as the Exiga, the system includes front and rear driveshafts to transfer power to both the front and rear axles, improving grip on slippery surfaces and delivering a balanced driving experience.

The 2018 Subaru Exiga's symmetrical all-wheel drive system is designed to provide excellent stability and control, especially in challenging driving conditions, such as rain or gravel roads, which are quite common in Australia. The driveshafts in this system endure a fair amount of stress and require regular attentiveness to keep them functioning correctly and safely.

When it comes to maintenance, driveshafts tend not to be something owners think about every day, but it's smart to give them some attention during routine servicing. Problems with driveshafts can manifest as unusual vibrations, clunking noises, or difficulty in steering, which means a prompt inspection can save bigger repairs down the track.

• Regular inspection: Mechanics should check the constant velocity (CV) joints and rubber boots that protect the driveshafts during scheduled servicing. Cracks or tears in these boots can allow dirt and moisture in, leading to premature wear or failure.
• Greasing and lubrication: Although many driveshafts in modern vehicles use sealed joints, some older or specific models might require lubrication. It's essential to follow Subaru's maintenance schedule to know the requirements for the Exiga.
• Check for vibrations or noises: If the driver notices any vibrations or unusual noises, especially during acceleration or turning, it might signal a worn driveshaft or damaged CV joint requiring immediate attention.
• Replacement intervals: Driveshafts don't have a fixed lifespan but usually last well over 150,000 kilometres if maintained properly. However, rough driving conditions or accidents can reduce their longevity.

Replacement of driveshafts or their components should always be done by qualified technicians using genuine Subaru parts to ensure proper fit and functionality. Incorrect installation can lead to imbalance and further damage to the drivetrain or suspension components.

Another key point for Subaru Exiga owners is ensuring that any work on the driveshafts includes an inspection of related components such as wheel bearings, differential assemblies, and suspension parts. Since all these parts work together to deliver smooth power transfer and control, a holistic approach to servicing can prevent future issues and keep the vehicle running smoothly.

Being proactive with driveshaft care also helps maintain fuel efficiency and the overall driving experience. Worn or damaged driveshafts create drag on the drivetrain, making the engine work harder and potentially reducing fuel economy. On top of that, drivetrain issues can cause uneven tyre wear, leading to more frequent replacements and added costs.

For Subaru Exiga drivers who enjoy excursions off the beaten path or frequently experience rough road surfaces, paying close attention to the condition of driveshafts is extra important. Passing through water, mud, and rough terrain can cause damage to protective CV boots and lead to accelerated wear. Regularly washing the undercarriage and checking the driveshaft boots can prevent dirt build-up and corrosion.

In wrapping up, driveshafts are very much relevant to the 2018 Subaru Exiga. Their role in Subaru's renowned all-wheel-drive system is vital for the vehicle's performance, safety, and drivability. Keeping an eye on the condition of driveshafts and performing routine maintenance actions will help ensure the Exiga remains reliable and ready for whatever the road or weather throws its way.
