Parts for your 2015 Subaru Exiga-Driveshafts

Understanding Driveshafts on the 2015 Subaru Exiga and How to Keep Them in Great Shape

The 2015 Subaru Exiga is a popular choice for families and outdoor enthusiasts alike, known for its spacious interior and reliable performance. When it comes to the heart of its powertrain, particularly the driveshafts, it's useful to know how these components function and why they matter. For those who aren't gear heads, driveshafts might sound like a complicated part, but they play a crucial role in getting the power from the engine to the wheels, allowing the vehicle to move smoothly on the road.

The Subaru Exiga, depending on the specific model and drivetrain configuration, typically uses an all-wheel-drive system. Subaru is well-known for its symmetrical all-wheel drive (AWD), which means that power is distributed to all four wheels for improved traction and stability. This system usually involves the use of driveshafts to transfer power from the transmission and differential to the wheels. On a 2015 Subaru Exiga, driveshafts are most definitely a key component, especially in AWD variants.

So, what exactly is a driveshaft? Simply put, a driveshaft is a mechanical shaft that transmits torque from the vehicle's engine or transmission to the wheels. It is responsible for delivering the engine's power to the wheels so the car can move forward or backward. In AWD cars like the Exiga, there are usually multiple driveshafts: one or more connected to the front wheels and additional ones to the rear wheels through the centre differential. This setup ensures that all wheels can receive power efficiently.

Driveshafts are made to be strong and durable as they are subjected to a lot of rotational forces while the vehicle is in motion. They typically include components such as the universal joints (U-joints) or constant velocity joints (CV joints), which allow for flexibility and smooth transmission of power even when the wheels and suspension are moving independently over rough or uneven terrain.

Maintaining the driveshafts on your 2015 Subaru Exiga is important for several reasons:

• Preventing Vibrations: A worn or damaged driveshaft can cause noticeable vibrations that become worse at higher speeds. These vibrations are not just annoying but can also indicate serious mechanical issues.
• Ensuring Smooth Power Delivery: Faulty driveshaft components can cause shuddering or jerking when accelerating or turning.
• Avoiding Noise: Clicking or clunking noises during gear changes or while driving can be a sign that the CV joints or U-joints need attention.
• Preserving Other Components: A failing driveshaft can place additional stress on the transmission and differential, leading to costly repairs.

When it comes to inspecting or replacing the driveshafts on a Subaru Exiga, it is wise to get into a regular maintenance routine. Here are some pointers for looking after your driveshafts:

1. Regular Inspection: During servicing, mechanics will check the condition of the boots surrounding the CV joints for cracks or tears. Damaged boots can let dirt and moisture in, leading to joint failure.
2. Listen for Noises: Pay attention to any unusual sounds coming from underneath the car, especially when turning or accelerating.
3. Feel for Vibrations: Notice if there are new vibrations when driving, specifically at higher speeds.
4. Keep it Greased: CV joints and U-joints rely on proper lubrication. If the grease leaks out due to damaged boots, these parts can wear out quickly.
5. Replace When Necessary: Driveshaft components do wear out over time, especially if the vehicle is used in demanding conditions like off-roading or carrying heavy loads. When a driveshaft or its joints fail, replacement is the best option rather than repair.

Replacing driveshafts on the 2015 Subaru Exiga is not typically a DIY job due to the complexity and the need for special tools. It's best left to professionals who are familiar with Subaru's AWD system. Using genuine or high-quality aftermarket parts is advisable to maintain the vehicle's handling and drivetrain reliability.

In a regular servicing schedule, the mechanic may recommend checking the driveshafts approximately every 50,000 kilometres or sooner if any symptoms appear. Subaru's reputation for durability means these parts generally last a fair distance before needing attention, but preventive care always pays off in avoiding breakdowns and maintaining smooth driving performance.

For those living in Australia, where road conditions can vary from smooth highways to rough rural tracks, the driveshafts on an AWD vehicle like the Subaru Exiga play a vital role in providing that confidence and traction in all situations. Keeping these components in top condition helps ensure the vehicle remains safe, reliable and enjoyable to drive, no matter where the road takes you.

So, if the owner of a 2015 Subaru Exiga is looking to maintain their car's drivetrain health, they should consider routine driveshaft checks part of their car servicing. Whether it's a quick visual inspection of the CV boots or a full replacement of a worn shaft, taking care of driveshafts helps keep the wheels turning smoothly and the adventure going strong.
