Centre-Bearing on the 2022 Subaru Outback: What You Need to Know

When it comes to the 2022 Subaru Outback, the question of whether a centre-bearing is present or necessary is a common one. To shed some light on this, it's important to first understand what a centre-bearing is and why some vehicles have them. However, the good news for owners of the 2022 Subaru Outback is that this particular model does not use a centre-bearing in its drivetrain system.

So, why is a centre-bearing not relevant or fitted to the 2022 Subaru Outback? The key lies in the design of Subaru's drivetrain and the type of transmission and driveshaft setup used in this vehicle. The Outback employs a symmetrical all-wheel-drive system paired with a CVT (Continuously Variable Transmission) or, in some models, a linear-tronic system. This setup utilises driveshafts that do not require an intermediate support for a long shaft, which is where a centre-bearing would typically be found.

A centre-bearing is often used in vehicles that have a two-piece driveshaft. This is common in rear-drive or four-wheel-drive vehicles with a front engine where the driveshaft spans a long length from the transmission to the rear differential. To support the driveshaft and reduce vibration and movement, a centre-bearing is positioned roughly in the middle.

In the Subaru Outback's case, the drivetrain design features shorter individual driveshafts that connect directly from the transmission output to the front and rear differentials. Each driveshaft operates independently with constant velocity (CV) joints that allow for smooth power delivery and articulation. Because the driveshafts are short and sturdy, and not one continuous length, the need for an intermediate bearing to support a long shaft is eliminated.

Ignoring a centre-bearing replacement or maintenance on this vehicle is of no concern simply because there isn't one installed. This design choice enhances reliability and lowers maintenance requirements for the Outback, giving owners one less component to worry about. Furthermore, the symmetrical all-wheel-drive system built into the chassis architecture effectively balances power distribution and driveline operation without the need for a centre-bearing.

Instead of a centre-bearing, the Subaru Outback relies on its CV joints and other drivetrain components for smooth operation. These require regular inspection and maintenance, particularly the CV joint boots, which protect the joints from dirt and moisture. Any cracks or tears in these boots should be addressed quickly to avoid more expensive repairs down the track.

Although the centre-bearing doesn't apply here, Subaru vehicles, including the Outback, do have other important drivetrain components that need attention. Routine servicing usually includes checking the condition of the driveshafts, CV joints, transmission mountings, and differential fluids. Proper maintenance of these components ensures the vehicle's smooth and efficient all-wheel-drive performance, especially when tackling rough terrain or long distance cruising.

In short, the 2022 Subaru Outback's engineering choices contribute to a robust and low-maintenance drivetrain without the complexity of a centre-bearing. This means owners can enjoy the benefits of Subaru's renowned symmetrical all-wheel-drive system without the extra fuss that might come with a two-piece driveshaft needing a centre-bearing.
