Parts for your 2016 Subaru Legacy-Driveshafts

Driveshafts on the 2016 Subaru Legacy: What You Need to Know

The 2016 Subaru Legacy is a standout vehicle in the midsize sedan segment, well-known for its all-wheel drive capability and reliable performance. When it comes to the drivetrain, many wonder about the role of driveshafts in the Legacy and whether they are actually used. To answer this, it helps to understand the vehicle's layout and how Subaru engineers have designed the system.

The 2016 Subaru Legacy features Subaru's signature symmetrical all-wheel drive (AWD) system. In this setup, power from the engine is sent to a centre differential, which then distributes torque to both the front and rear axles. This means the vehicle makes use of what's called a "driveshaft," but not in the way you might picture for traditional rear-wheel drive cars.

Unlike rear-wheel drive cars that have a long driveshaft running the length of the vehicle from the transmission to the rear differential, the Legacy's AWD system uses a shorter driveshaft specifically to transmit power from the gearbox to the rear differential. So, yes, driveshafts are indeed fitted on the 2016 Subaru Legacy. They are a crucial component for distributing torque to ensure that all four wheels get power, improving traction and stability in various driving conditions.

Driveshafts essentially serve as the link between the transmission and the axles, allowing power to be transferred smoothly while accommodating the movement of the suspension and steering. In the Legacy's AWD system, the centre driveshaft runs underneath the vehicle and connects the front transaxle to the rear differential. From there, half shafts branch out to each rear wheel.

Understanding the driveshaft's role helps highlight why maintenance and replacement, when necessary, are important. Driveshafts endure constant motion, torque, and stress, so they require attention just like any other mechanical part.

When it comes to maintaining the driveshafts of a 2016 Subaru Legacy, keeping an eye on things like the CV joints, boots, and universal joints is key. CV (constant velocity) joints allow the driveshaft to flex while still transmitting power smoothly, especially when the suspension moves or the wheels turn. The boots around these joints protect them from dirt, moisture, and debris, which can cause wear and eventual failure.

If the boots develop cracks or tears, dirt and moisture can get inside, leading to joint damage. This can cause clicking noises when turning, vibrations, or even loss of power transmission to the rear wheels. Regular inspections during servicing can catch these issues early, making it easier and cheaper to fix than waiting for complete driveshaft failure.

Replacing a driveshaft or its components on the 2016 Legacy isn't overly complicated, but it should be done by someone familiar with Subaru's AWD system to ensure everything is balanced and aligned properly. When a driveshaft is replaced, technicians will often check the surrounding components too, like the rear differential fluid and suspension parts, to make sure the whole system works seamlessly.

Routine servicing generally includes checking the condition of the CV boots and driveshaft joints. If any grease leaks or boots are damaged, timely repairs can extend the life of the driveshafts. For those who enjoy tackling their own vehicle maintenance, it's worth having a look under the car regularly, especially if you often drive on rough or unsealed roads where dirt and stones can accelerate wear.

In summary, driveshafts are very much a part of the 2016 Subaru Legacy's engineering, playing a vital role in its all-wheel drive system. Proper care and maintenance help keep the drivetrain running smoothly, ensuring the Legacy's excellent handling and traction remain uncompromised. If you hear unusual noises or notice vibrations while driving, it's a good idea to have the driveshafts checked out as part of your regular vehicle servicing to avoid bigger headaches down the track.
