Driveshafts and the 2017 Subaru Forester: What You Need to Know

The 2017 Subaru Forester is a popular compact SUV known for its reliability, all-wheel-drive capability, and smooth handling. When it comes to understanding the components that help deliver power from the engine to the wheels, driveshafts are often a key discussion point for many vehicles. But are driveshafts actually used in the 2017 Subaru Forester? The short answer is yes, but with a bit of nuance.

The Subaru Forester utilises a symmetrical all-wheel-drive system that features a flat boxer engine coupled with a transmission sending power to both front and rear wheels. The driveshafts in this setup are essential components responsible for transferring rotational force from the transmission and transfer case to the front and rear axles.

Specifically, the Forester has front driveshafts attached to the front differential and rear driveshafts that run to the rear differential. These shafts are often called half-shafts or axle shafts, as they connect the differential to each wheel, allowing torque to reach the wheels while accommodating suspension movements and steering angles.

The purpose of driveshafts in the Forester is pretty straightforward. They act as the link transmitting power, and because the Forester's AWD system is designed for both on-road stability and light off-road capability, these driveshafts play a critical role in ensuring power is delivered smoothly and reliably to all wheels under various conditions.

Looking at driveshafts from a maintenance perspective, it's important for Forester owners to keep an eye on these components because they endure a fair bit of stress. The driveshafts' outer ends are usually fitted with Constant Velocity (CV) joints, which allow flexibility for the wheels to turn and move up and down. CV joints are covered with rubber boots designed to protect them from dirt, water and debris.

Over time, these CV boots may crack or tear, leading to grease leaking out and contaminants getting in. This causes the joints to wear rapidly, resulting in clicking noises when turning, vibrations while driving, or even complete driveshaft failure if left untreated.

Regular inspection of the driveshaft CV boots and joints during servicing is strongly recommended for the 2017 Subaru Forester. If any damage is noticed, it is advisable to replace the CV boots promptly or the entire driveshaft if the joint has already worn significantly.

Other common signs of driveshaft issues include excessive vibrations during acceleration or at higher speeds and unusual knocking sounds when driving over bumps. These symptoms can indicate worn CV joints, imbalanced shafts or damaged bearings, all of which reduce driveline efficiency and affect vehicle handling.

If a driveshaft replacement becomes necessary, it is best to use genuine Subaru parts or high-quality aftermarket components designed to fit the Forester's specifications. Proper installation requires attention to correct torque settings, alignment and balancing to avoid premature wear.

For those keen on DIY maintenance, checking CV boots for cracks or grease leaks is a good start. Cleaning around the boots to remove dirt and grime helps extend their lifespan. However, more complex work like replacing entire driveshafts or CV joints is typically best left to experienced technicians who can ensure everything is refitted to factory standards.

In general, keeping the driveshafts in good condition helps maintain the Forester's smooth AWD performance, fuel efficiency and overall driving comfort. Since the Forester is often driven in diverse environments ranging from city streets to gravel roads and light trails, preventing driveshaft failure can save on expensive repairs down the track.

Every drive shaft is designed to handle torque loads and suspension articulation unique to the Forester's chassis and powertrain layout. This means any modifications or upgrades should be approached with caution to avoid compromising the driveshaft's durability or the vehicle's safety.

Given the 2017 Subaru Forester's AWD system relies heavily on its driveshafts for power distribution, it's clear these parts are very relevant. Regular check-ups during servicing, paying attention to any signs of wear or damage, and timely replacement of faulty driveshaft components ensure this trusty SUV stays on the road delivering dependable performance for many kilometres to come.
