Centre-Bearing and the 2020 Subaru Outback: What You Need to Know

The 2020 Subaru Outback is a popular choice among Aussie drivers who love a blend of rugged capability and everyday comfort. When it comes to understanding whether a centre-bearing is part of this vehicle's drivetrain setup, it's important to dig into the technical details to get a clear picture.

So, does the 2020 Subaru Outback use a centre-bearing? The short answer is no, it does not have a centre-bearing in its drivetrain. This is primarily because of the specific design of Subaru's all-wheel-drive system and the layout of the Outback's drivetrain components.

Centre-bearings are typically found in vehicles that have a two-piece driveshaft system. These bearings support the driveshaft where it is split into two sections, holding the shaft in place and reducing vibrations during rotation. Cars or SUVs with longer wheelbases often need this setup to allow for a shorter, manageable driveshaft length and to maintain smooth power delivery to the back wheels.

However, the 2020 Subaru Outback uses a different kind of drivetrain layout. Subaru employs a symmetrical all-wheel-drive system that is well-known for its simplicity and efficiency. Instead of a multi-piece driveshaft with a centre-bearing, the Outback uses a direct driveshaft connection from the transmission to the rear differential. This single-piece driveshaft arrangement is supported at the ends by the transmission and rear differential bearings without requiring a centre support.

The reason no centre-bearing is necessary boils down to the outback's design choices. The Outback's wheelbase and drivetrain configuration allow the use of a single, robust driveshaft that is rigid enough to handle the stresses of power delivery without the need for a centre support bearing. This results in fewer parts that could wear out, and less complexity under the vehicle, which means simpler maintenance for owners.

For those who own or are considering a 2020 Subaru Outback, it's worth noting that while no centre-bearing is present, other components do require regular checks and maintenance. Components such as the driveshaft itself, universal joints (U-joints), and the differential need attention to ensure the AWD system continues to function smoothly and efficiently.

Now, for vehicles that do have a centre-bearing, here's a quick rundown of why this part is important and what should be done to keep it in good shape. A centre-bearing is mounted in the middle of a two-piece driveshaft and acts as a support by bearing the weight and torque loads of the shaft. It greatly reduces vibration and prevents the shaft from wobbling or becoming unstable at higher speeds.

The centre-bearing also contains a rubberised or elastomeric cushion that helps absorb shocks and vibrations from the road, making the ride more comfortable and protecting other drivetrain components from damage. If the centre-bearing wears out or fails, you might notice clunking noises, vibrations through the floor of the vehicle, or shudders when accelerating.

Maintenance of a centre-bearing typically involves regular inspections during servicing. Mechanics will check for any excessive play, cracking or degradation of the rubber cushion, and signs of bearing wear such as rough rotation. If there is any sign of failure, the centre-bearing should be replaced promptly to avoid further damage to the driveshaft or rear differential.

Although this doesn't apply to the 2020 Subaru Outback, many cars that require a centre-bearing have straightforward replacement procedures but it's recommended to have a qualified technician carry out the job. Proper alignment and balancing of the driveshaft are critical to avoid premature wear of a new bearing or causing additional vibration issues.

For 2020 Subaru Outback owners, the takeaway is that the absence of a centre-bearing means fewer potential points of drivetrain failure and easier maintenance routines. While regular servicing still involves checking the health of the driveshaft and other components, the one-piece driveshaft design makes the Outback a bit more hassle-free when it comes to this aspect of drivetrain care.

Keeping an eye on other parts like U-joints and differential fluid levels will help ensure the AWD system continues to deliver strong performance both on tarmac and when heading off the beaten track. The Subaru Outback's design philosophy emphasises durable components and reliable operation, so fewer moving parts like a centre-bearing fit well with that approach.

Ultimately, even though the 2020 Subaru Outback does not have a centre-bearing, understanding the role of this component in other vehicles can help car owners appreciate how different drivetrain designs impact maintenance needs and vehicle longevity. For Outback owners, sticking to the recommended service schedule and giving the vehicle a thorough check during each service visit is the best way to enjoy worry-free driving across Australia's diverse terrain.
