Parts for your 2012 Subaru Forester-Driveshafts

Understanding the Driveshafts in the 2012 Subaru Forester

The 2012 Subaru Forester is a popular compact SUV, well-regarded for its reliable performance and symmetrical all-wheel drive system. When it comes to the vehicle's drivetrain, driveshafts play an important role, connecting the transmission to the wheels to transmit power. Specifically, in Subaru's all-wheel drive layout, driveshafts are indeed fitted to the Forester, making them an essential component to understand and maintain for any owner.

Driveshafts, also sometimes called propeller shafts or half-shafts, are the crucial link between the engine's power and the wheels on your 2012 Forester. Because the Forester uses a boxer engine paired with a symmetrical all-wheel drive system, power is sent from the engine through the transmission and then via driveshafts to both the front and rear wheels. This setup improves the vehicle's stability, traction, and off-road capabilities, which is exactly what many Forester drivers rely on.

The driveshafts consist of steel shafts equipped with constant velocity joints (CV joints) on either end. These CV joints allow the driveshaft to flex and transmit torque smoothly despite different suspension movements, wheel alignment, and steering angles. Without driveshafts, the wheels would not receive the power necessary for movement, and the AWD system simply wouldn't function as intended.

Given the role of driveshafts in a 2012 Subaru Forester, maintaining them is key to keeping the vehicle running smoothly. Over time, driveshaft components such as the CV joints and boots encounter wear and tear, mostly from exposure to road debris, moisture, and natural ageing. If a driveshaft becomes worn or damaged, it can cause noticeable problems including clicking noises during turns, vibrations while driving, or even loss of power to the wheels.

Regular servicing for the driveshafts generally involves inspecting the CV boots for cracks or tears. These rubber boots protect the CV joints by keeping grease in and contaminants out. When a boot fails, grease can leak, and dirt can enter, leading to joint wear. It's a good idea to check these boots at least once a year or more frequently if driving in rough or off-road conditions, where the Forester often excels.

If the CV boots or joints show signs of damage, replacement is recommended to prevent further drivetrain issues. Replacing a damaged driveshaft or CV joint might seem daunting, but it is a relatively common repair for the Forester and can significantly improve driving smoothness and safety. Mechanics will typically remove the damaged driveshaft and install a new or refurbished unit. The process involves careful removal of suspension components to access the driveshaft, so it is often best left to professionals.

Here are some easy techniques every Forester owner can keep in mind to prolong the life of their driveshafts:

• Keep an eye on any unusual noises from the wheels, particularly when turning.
• Inspect CV boots during routine tyre changes or oil changes.
• Avoid harsh off-road driving or deep water crossings which can accelerate wear of the driveshaft components.
• Ask your mechanic to check driveshaft condition during clutch changes or transmission servicing.

Ignoring driveshaft problems can lead to more severe outcomes, such as complete joint failure. That can leave the vehicle unable to move or cause damage to other drivetrain components, resulting in costly repairs. Luckily, by catching issues early and servicing the driveshafts properly, the Forester can continue to offer its hallmark reliability and confident four-wheel-drive performance.

All up, driveshafts are very much part of the 2012 Subaru Forester's drivetrain setup. They are vital in delivering power to all four wheels, enabling that famous Subaru grip and control across various terrain types. Proper maintenance of the driveshafts keeps the all-wheel-drive system operating efficiently and helps avoid unexpected breakdowns. For anyone driving a 2012 Forester, understanding this component and giving it some attention during servicing will go a long way towards enjoying a smooth and capable ride for years to come.
