Parts for your 2019 Subaru Legacy-Driveshafts

Understanding Driveshafts in the 2019 Subaru Legacy

The 2019 Subaru Legacy is a popular choice among Aussie drivers for its reliability, performance, and all-wheel drive capabilities. When talking about the drivetrain components, one key part that often comes up is the driveshaft. So, does the 2019 Subaru Legacy use driveshafts? The simple answer is yes, but with some specifics to consider because of its unique Subaru symmetrical all-wheel drive system.

Subaru's all-wheel drive technology in the Legacy utilises driveshafts to transfer power from the engine and transmission to the wheels. Unlike traditional front-wheel-drive vehicles where you might only find half-shafts, the AWD setup means there are driveshafts responsible for powering both the front and rear wheels, providing better grip and stability especially on slippery Aussie roads or in rough terrain.

Driveshafts in the 2019 Subaru Legacy play a crucial role in delivering engine power efficiently and smoothly to the wheels. The vehicle's box-flat engine (also known as a boxer engine) sits low in the chassis, contributing to a lower centre of gravity which enhances handling. The driveshafts connect this engine's output through the transmission to the front wheels and a central differential, then continuing power out to the rear wheels through another set of driveshafts. All of this combines to give the driver excellent control and traction whether cruising on highways, commuting through city streets, or tackling less-than-ideal weather conditions.

Maintaining the driveshafts is an important part of looking after a 2019 Subaru Legacy. While they are designed to be durable, like any mechanical part that moves and transfers power, driveshafts can wear out or develop issues over time. One of the most common things to watch for is wear or damage to the CV joints (constant velocity joints) at the ends of the driveshafts. These joints allow the shafts to flex when turning or driving over bumps without losing power transfer efficiency.

Signs that driveshafts or related components may need servicing include unusual noises like clicking or popping during turns, vibrations felt through the steering wheel, or excessive grease leaks around the CV boots. If left unaddressed, damaged driveshafts can lead to poor handling, loss of power to the rear wheels, and even breakdowns, which are not great if you're out on a long drive or commuting daily.

Regular inspection during servicing is a smart move for longevity. Subaru service centres usually check the CV boots condition and look for any signs of cracking, tears, or grease leaking which suggests worn joints. Replacing a damaged CV boot early can prevent costly driveshaft or joint failure. For those driving their Legacy in harsh conditions such as dusty outback roads or salty coastal environments, keeping an eye on driveshaft condition is especially important.

If the driveshaft itself needs replacement, it is a job best left to professionals due to the complexity and precision required to balance the shafts correctly. Poorly fitted driveshafts can cause vibrations and premature wear to other drivetrain components. Genuine Subaru parts are recommended to ensure compatibility and maintain the vehicle's all-wheel drive performance and safety.

Some DIY maintenance owners might consider greasing the CV joints if they have access to appropriate tools and manuals, but for most, scheduled visits to a Subaru mechanic are the best way to ensure driveshafts stay in top shape. The 2019 Subaru Legacy's all-wheel drive system relies heavily on these components, not just for delivering power but also for the smooth, stable ride that fans of the vehicle appreciate.

So, while it may seem like just another shaft under the car, driveshafts in the 2019 Subaru Legacy are an essential link in the chain that keeps the car moving, safe, and enjoyable to drive. Proper attention to these parts as part of routine servicing will keep the Legacy running like a dream well beyond the new car period.
