Parts for your 2016 Subaru Impreza-Centre bearing

Centre Bearing on the 2016 Subaru Impreza: Is It Needed?

The 2016 Subaru Impreza is known for its reliable AWD system and balanced drivetrain setup, but when it comes to the centre bearing, things get a little more specific. A centre bearing is a component often used in vehicles that have a long driveshaft divided into two sections. It serves as both a support point and a vibration damper, holding up the driveshaft where it can otherwise wobble or sag under its own weight. However, in the case of the 2016 Subaru Impreza, a centre bearing is not actually part of the drivetrain design.

Why is a centre bearing absent from this model? The answer lies in the design of the Impreza's powertrain. The 2016 Impreza uses a symmetrical all-wheel-drive system with a relatively short driveshaft that runs from the front-mounted boxer engine and transmission to the rear differential. The driveshaft in this setup is generally a solid, single piece or consists of short shafts that do not require mid-shaft support. Because the driveshaft length is not excessive and the overall layout is compact, the engineers opted out of incorporating a centre bearing.

This absence of a centre bearing has a few practical benefits. First, it reduces the number of parts that could wear out and need replacing. Fewer components mean less chance for vibration issues and mechanical failures. It also simplifies the maintenance and repair process.

In contrast, vehicles with longer driveshafts or a two-piece shaft design rely on a centre bearing to hold things in place and avoid driveline vibrations. Without adequate support, a long driveshaft could become unstable or experience excessive wear at the universal joints.

So for anyone working on or servicing a 2016 Subaru Impreza, there is no need to be concerned about centre bearing replacement or maintenance simply because the part is not present. Instead, attention should be paid to other parts of the drivetrain, such as the CV joints, universal joints, and differential seals, which are more relevant to the Impreza's AWD system.

While servicing the Impreza, keeping an eye on the driveshaft boots and joints will go a long way in ensuring smooth operation. Grease leaks, cracks in boots, or unusual noises should be addressed promptly to avoid issues that can impact the vehicle's driveability.

In summary, the 2016 Subaru Impreza does not use a centre bearing due to its compact and efficient drivetrain design. The use of a short, single driveshaft eliminates the need for the support and vibration-damping function that a centre bearing provides in other vehicles. This design choice simplifies maintenance and reduces potential points of failure, allowing the Impreza to maintain its reputation for reliability and smooth all-wheel-drive performance.
