Centre Bearing for the 2020 Subaru Legacy: What You Need to Know

When it comes to the 2020 Subaru Legacy, many drivers might wonder if the vehicle uses a centre bearing as part of its drivetrain setup. After referring to detailed technical sources, it turns out the 2020 Subaru Legacy does not have a centre bearing. This is largely due to the vehicle's design and the way power is transmitted to the wheels.

The centre bearing is typically found in vehicles with a two-piece driveshaft. This consists of an intermediate shaft connected by a bearing, which supports the driveshaft and helps reduce vibrations while maintaining alignment as it spins. However, the 2020 Subaru Legacy doesn't utilise a two-piece driveshaft arrangement. Instead, Subaru's confident use of a single-piece driveshaft system in this model eliminates the need for a centre bearing altogether.

Why is that the case? The Subaru Legacy features Subaru's hallmark symmetrical all-wheel-drive system which runs power through a relatively short single driveshaft that goes from the transmission to the rear differential. Since the shaft is not overly long or segmented into parts, there is no need for a bearing to support it halfway along its length.

The absence of a centre bearing actually simplifies the drivetrain setup. Less complexity can mean fewer components to wear out or require maintenance, which is a bonus for any Subaru Legacy owner. Additionally, a single-piece driveshaft reduces potential points of failure and helps maintain more consistent drivetrain smoothness.

That said, while the 2020 Subaru Legacy doesn't need a centre bearing, it still relies on other components to keep the driveshaft and overall drivetrain healthy. Universal joints, transmission fluid, differential oil, and CV joints are all parts that take on a lot of the work in terms of flexibility, dampening vibration, and smooth power delivery.

If a car does have a centre bearing, which is more common in larger SUVs, trucks or vehicles with longer driveshafts, that component plays a crucial role. The centre bearing supports the driveshaft, reducing vibrations and preventing it from wobbling or moving out of alignment. This helps protect the driveshaft and other drivetrain components from excessive wear or damage.

On vehicles with a centre bearing, maintenance usually involves checking the condition of the bearing for wear or damage. Over time, the rubber or metal components that cushion the bearing can deteriorate, leading to more vibration or even failure. Signs that the centre bearing may need attention include unusual noises, noticeable vibration under acceleration, or physical inspection showing cracked or degraded bearing material.

When it comes to replacing a centre bearing, it's essential to get the job done properly. That means removing the driveshaft, carefully detaching the old bearing, and fitting a new one with all the correct torque specs and alignment settings. Thankfully, for Subaru Legacy owners, this isn't a concern since the design doesn't call for a centre bearing in the first place.

Subaru drivers with a 2020 Legacy will find that their maintenance priorities rest on other areas like regular fluid changes, ensuring CV joints are in good shape, and monitoring other drivetrain components for wear. Keeping on top of these will help the vehicle run smoothly and quietly - just what you want when you're on the road in Australia's diverse conditions.

So while the centre bearing plays an important role in many rear-wheel-drive or four-wheel-drive vehicles with long or segmented driveshafts, it simply isn't relevant for the 2020 Subaru Legacy. The car's clever engineering and compact drivetrain layout mean there's no centre bearing to maintain, repair or replace. That can be one less thing for Legacy owners to worry about, allowing them to focus on enjoying the ride and keeping up with Subaru's recommended servicing schedule.
