Parts for your 2016 Subaru Outback-Driveshafts

Understanding Driveshafts in the 2016 Subaru Outback

The 2016 Subaru Outback is well-known for its all-wheel-drive system, which provides excellent traction and stability in various driving conditions. When it comes to the drivetrain components, such as driveshafts, it's important to understand whether this vehicle uses them and why. Let's dive into the details about driveshafts in this particular model and what their role would be if fitted.

In many vehicles, driveshafts are crucial components that transfer power from the transmission or transfer case to the differentials and then to the wheels. However, the 2016 Subaru Outback does not use traditional long driveshafts like you might find in rear-wheel-drive or some four-wheel-drive vehicles. Instead, it features a more compact and integrated drivetrain setup that suits its Subaru Symmetrical All-Wheel Drive system.

The Subaru Outback's AWD system relies on a gearbox integrated with the transmission that sends power to front and rear axles via shorter driveshafts commonly referred to as axle shafts or half shafts. These are connected directly to the wheels and are responsible for transmitting the engine's torque to turn the wheels, but they are not the same as the larger, longer driveshafts seen in other drivetrain layouts.

So why doesn't the 2016 Subaru Outback use long driveshafts? The answer lies in its design philosophy and drivetrain layout. Subaru's symmetrical AWD setup uses a flat boxer engine placed low and centrally along with a transmission that sends power evenly to the front and rear. This layout eliminates the need for a long, central driveshaft running the length of the vehicle, which is more typical in other AWD/4WD vehicles that use a transfer case. Instead, shorter shaft assemblies connect the transaxle directly to the wheels.

Since the 2016 Subaru Outback uses these shorter axle shafts rather than a traditional driveshaft, understanding the maintenance and replacement of driveshafts is slightly different. While there is no central driveshaft to worry about, the axle shafts are key components that still require attention to keep the car running smoothly and safely.

Generally, axle shafts in the Outback are durable but can suffer from wear over time, particularly their constant velocity (CV) joints and associated boots. CV joints allow the wheels to turn and move up and down with the suspension while still transmitting power efficiently. The rubber boots that cover the joints protect them from dirt, water, and debris, but once they crack or tear, grease can leak out, and contaminants get in. This can quickly lead to joint failure causing clicking noises when turning, vibrations, or even loss of drive to that wheel.

In terms of servicing, checking the CV boots and axle shafts should be part of regular maintenance, especially if the Outback has been driven through tough conditions, rough roads, or off-road. Mechanics usually inspect for any grease leaks or damage during routine services or tyre rotations.

If a driveshaft (or more accurately, the axle shaft) replacement becomes necessary, it's usually due to CV joint failure or shaft damage from impact or wear. Replacing these parts on a 2016 Outback typically involves removing the wheel, brake components, and possibly the hub assembly to access the shaft. While not the simplest job, a competent mechanic can handle it without much fuss. Using quality replacement parts is important to maintain the vehicle's AWD performance.

Regular inspections can help avoid major issues. If the vehicle starts showing any unusual noises, vibrations, or handling quirks under acceleration or while turning, it's a good idea to have the axle shafts checked. Addressing minor damage early can save money and keep the vehicle safe and reliable.

• Check CV boots regularly for cracks or leaks.
• Listen for clicking or popping noises when cornering.
• Pay attention to vibrations during acceleration.
• Have axle shafts inspected after an impact or rough off-road use.
• Use quality parts for replacements to retain AWD performance.

So even though the 2016 Subaru Outback does not feature traditional long driveshafts, it still relies heavily on shorter axle shafts for power delivery to all four wheels. Maintaining these components is essential for preserving the vehicle's renowned stability and traction. Getting familiar with the setup and keeping up with regular inspections can ensure your Outback keeps running quietly and confidently, no matter the road conditions.
