Parts for your 2015 Subaru Forester-Driveshafts

Understanding Driveshafts on the 2015 Subaru Forester

The 2015 Subaru Forester is a popular compact SUV known for its all-wheel-drive capability and reliable performance. When it comes to its drivetrain, the Forester uses Subaru's signature Symmetrical All-Wheel Drive system. This drivetrain layout involves components that transmit power from the engine and transmission to all four wheels, improving traction and stability across different terrains.

One key component in many vehicles that transfer power from the transmission to the wheels is the driveshaft. Driveshafts are typically long metal shafts that spin to carry torque from the engine or transmission to the axles. However, in the case of the 2015 Subaru Forester, the term 'driveshaft' is not commonly used in the same way as in vehicles with a conventional rear-wheel or four-wheel drive layout.

In the 2015 Forester, power delivery to the wheels is managed by a combination of the transmission, a centre differential, and shorter axle shafts. While some might think the Forester lacks driveshafts altogether, it does have components that serve a similar purpose by transferring rotational force from the powertrain to the wheels. These are often better described as CV (constant velocity) axles or half-shafts, rather than traditional driveshafts.

CV axles connect the transmission and differential to the wheels and feature flexible joints that allow smooth power transfer while accommodating the up and down motion of the suspension and steering. Essentially, instead of one long driveshaft running the length of the vehicle, the Forester utilises multiple shorter shafts with CV joints to deliver power efficiently. This design helps keep the vehicle compact and improves manoeuvrability.

Because the 2015 Subaru Forester relies on CV axles rather than a single driveshaft, maintenance and servicing focus mainly on these components. CV axles experience significant strain since they handle both rotational power and suspension movement, meaning their joints and boots must be kept in good condition to avoid damage.

Maintaining the 'driveshafts' or rather, the CV axles, on a 2015 Forester is an important part of keeping the car running smoothly. Regular checks during servicing will often include inspecting the CV joint boots for cracks or tears because if the boot is damaged, dirt and moisture can get inside and cause joint failure. If a CV joint goes bad, you might hear clicking or clunking noises when turning.

If replacement is necessary, it's advisable to use high-quality parts to ensure longevity and proper fit. This also often includes replacing the axle shaft alongside the joints to avoid dealing with recurring faults. Australia's varying conditions, from dusty outbacks to wet city roads, mean keeping CV boots intact is crucial to protect these components from corrosion and premature wear.

For anyone servicing a 2015 Subaru Forester, it's wise to have the CV axles inspected regularly, especially as the vehicle approaches or passes 100,000 kilometres. Often these parts will last well beyond this mileage, but conditions and driving habits determine their lifespan.

Replacing CV axles usually isn't a complicated job but it does require some technical know-how and the right tools. Workshop manuals specifically for the 2015 Forester provide detailed instructions on removal and installation, which involves dealing with suspension components and sometimes the gearbox centre differential.

Routine inspections can include a physical check of the boot condition, listening for unusual noises when cornering, and watching out for vibrations at higher speeds. Ignoring potential faults in these shafts might lead to sudden axle failure which can impact the car's handling or cause loss of power delivery to one or more wheels.

To help extend the life of these vital parts, it's a good idea to keep the underbody clean and free from salt and mud build-up, especially after off-road trips or wintery conditions that are common in parts of Australia. Proper lubrication within the CV joint is sealed inside the boot, but damage to the boot invites contamination.

In summary, while the 2015 Subaru Forester doesn't use a conventional driveshaft like some rear-wheel drive or four-wheel drive vehicles, it does rely on CV axles that perform the same crucial role of transmitting power from the transmission to the wheels. These shafts need care and attention as part of regular servicing to keep the Forester driving confidently no matter the road or weather.
