Centre Bearing on the 2012 Subaru Exiga: Is It Used and What You Need to Know

The 2012 Subaru Exiga is a versatile multi-purpose vehicle designed primarily for family use, offering a spacious interior and practical performance. When it comes to the drivetrain layout and components, it is important to understand whether features like a centre bearing play a role in this specific model. After referring to technical sources and Subaru's drivetrain designs, it turns out the 2012 Subaru Exiga does not use a centre bearing.

So, why is this the case? The answer lies in the vehicle's drivetrain setup. Most Subaru models, including the Exiga, rely on a boxer engine paired with a symmetrical all-wheel drive system that involves a relatively compact drive shaft design. Unlike some rear-wheel or four-wheel drive vehicles with long drive shafts that require a centre support bearing to maintain shaft alignment and reduce vibration, the Exiga's drive shaft is typically short enough and well-supported at its endpoints. This eliminates the need for a separate centre bearing to support an intermediate shaft section.

Centre bearings are generally used in vehicles where the driveshaft is split into two parts due to length. They help maintain balance, reduce vibrations, and support the rotating shaft somewhere in the middle of the vehicle. On cars with long body styles, rear-wheel or four-wheel drive configurations, this part is crucial to keep the driveline smooth and prevent premature wear. For the 2012 Subaru Exiga, since the driveshaft arrangement is straightforward and compact, a centre bearing is not relevant or installed.

Instead, the Exiga's drivetrain depends on robust CV joints and fixed universal joints that allow for smooth torque delivery and suspension movement without the necessity of intermediate support bearing components. Additionally, the symmetrical all-wheel drive system helps ensure torque is distributed efficiently without the strain on a long drive shaft that would otherwise necessitate a centre bearing.

For Subaru Exiga owners, this means maintenance and servicing concerns generally do not include the centre bearing as a component. The focus, rather, should be on the driveshaft joints and related parts to maintain proper function and vehicle performance.

However, for vehicles that do use centre bearings, understanding their role can be quite helpful. Centre bearings, also known as carrier bearings, serve to support the drive shaft in vehicles with two-piece drive shafts. They help minimise vibrations, reduce stresses on the shaft, and maintain correct alignment to prevent wear and tear on associated components. Over time, these bearings can wear out, leading to noises such as clunking or rumbling, vibrations during acceleration, or even shaking in the vehicle floor. If left unattended, a failing centre bearing can cause damage to the drive shaft and surrounding parts.

When it comes to replacement or maintenance of a centre bearing, it usually involves several important steps. First, it is critical to lift the vehicle securely on a hoist or jack stands to gain access to the driveshaft assembly. Next, the damaged bearing is identified and the driveshaft is split carefully at the connection points. Lubrication and careful handling are essential throughout to avoid damage to universal joints or CV joints. After removing the faulty bearing, the new centre bearing is installed ensuring proper fitment and alignment. Using OEM-quality components is highly recommended to ensure long-lasting performance.

Routine servicing of vehicles with centre bearings often includes visual inspections for signs of wear such as cracked rubber mounts, rust, or excessive play. Mechanics also listen for unusual noises coming from the drivetrain and check for vibrations that may indicate bearing fatigue. Proactive replacement before a bearing seizes or fails completely can help avoid breakdowns and costly repairs.

So while the 2012 Subaru Exiga does not incorporate a centre bearing in its drivetrain design, understanding the part and its purpose can help owners of other models or vehicles better grasp this crucial drivetrain component. For Exiga owners, focusing on proper maintenance of the driveshaft, CV joints, and suspension parts will ensure smooth and reliable performance on the road without the need to worry about a centre bearing.
