Centre Bearing on the 2013 Subaru Impreza: Is It Used and What You Need to Know

The 2013 Subaru Impreza, a popular Australian favourite, is known for its all-wheel-drive system and boxer engine configuration. But when it comes to the question of whether this vehicle uses a centre bearing, the answer is quite straightforward. The 2013 Subaru Impreza does not feature a centre bearing as part of its drivetrain.

Why is that the case? Well, the centre bearing is typically found in vehicles with a two-piece or split driveshaft setup, where the driveshaft is divided into sections to better accommodate longer distances or multiple angles in the driveline. The centre bearing supports the intermediate shaft, helping to reduce vibration and ensure smooth power transmission. This setup is more commonly seen in rear-wheel-drive or four-wheel-drive vehicles with a longitudinal engine layout and a longer driveshaft.

Subaru's unique design for the 2013 Impreza uses a flat boxer engine paired with a symmetrical all-wheel-drive system. Unlike some other AWD vehicles, it employs a relatively short and direct driveshaft arrangement from the transmission to the front and rear differentials. Because of this compact layout and the symmetrical AWD system, there isn't a need for a split driveshaft and, consequently, no centre bearing is fitted to the Impreza's drivetrain.

Since the 2013 Subaru Impreza's drivetrain doesn't include a centre bearing, there is no centre bearing to inspect, maintain or replace during servicing. Instead, attention is typically focused on other drivetrain components such as the CV joints, drive axles, and wheel bearings, which are more relevant to this vehicle's design.

CV joints, for example, play a critical role in Subaru's AWD system by allowing the driveshafts to flex while transferring power smoothly to the wheels, especially during cornering or suspension movement. They frequently require inspection and can wear out over time, particularly if the protective boots get torn. Keeping an eye on these parts will help the AWD system function properly without unnecessary vibration or noise.

The wheel bearings also take a significant amount of load and support the car's wheels during motion. These bearings can wear out or become noisy over time and should be checked during regular servicing to help avoid any handling issues or further damage to the suspension components.

Because the Impreza does not have a centre bearing, buyers and owners do not need to worry about some of the common issues that arise with this part in vehicles that use one. Centre bearings, if worn or damaged, can cause vibrations, noise, and eventual drivetrain failure, leading to potentially costly repairs. Subaru's choice of drivetrain layout for the Impreza means less complexity and potentially fewer maintenance headaches associated with split driveshafts and intermediate shaft support bearings.

If someone is unsure about their AWD drivetrain or hears unusual noises, it is always a good call to have qualified technicians inspect the full assembly. While this won't involve replacing a centre bearing, it might uncover other issues like worn CV joints, damaged drive axles, or other components that could be causing trouble.

So for those cruising around in a 2013 Subaru Impreza, rest assured that centre bearing servicing is simply not on the cards. The Impreza's drive system is designed for efficiency and durability without the need for this particular part. Instead, a well-maintained service routine focusing on the components tailored to its symmetrical AWD setup will keep the car running smoothly for years to come.
