Does the 2010 Subaru Exiga Have a Centre Bearing? Understanding Its Role and Maintenance

The 2010 Subaru Exiga, a versatile and spacious crossover wagon, is designed with Subaru's signature symmetrical all-wheel drive and boxer engine layout. When it comes to the drivetrain components, many owners and enthusiasts often ask about the centre bearing. So, does the 2010 Subaru Exiga use a centre bearing? After referencing Subaru technical manuals and reliable automotive sources, it is clear that the 2010 Exiga does not utilise a centre bearing in its driveline configuration.

Why is this the case? Well, a centre bearing is typically found in vehicles with a two-piece driveshaft setup. This bearing supports the intermediate shaft, allowing it to rotate smoothly while reducing vibrations and excess wear. The centre bearing sits between the transmission output and the rear differential input, especially in rear-wheel drive or four-wheel drive vehicles with long driveshafts.

In the 2010 Subaru Exiga's case, the vehicle uses a continuous or one-piece driveshaft, which links the front and rear drivetrain components without the need for an intermediate support bearing. Thanks to Subaru's symmetrical AWD system, the driveshaft is engineered to manage power transmission effectively, minimising the necessity for a centre bearing. This design simplifies the drivetrain and reduces maintenance points.

Because of this straightforward setup, there is no centre bearing fitted in the Exiga's drivetrain. This helps improve reliability, reduce complexity, and lower servicing costs over the vehicle's lifetime. So, owners do not need to worry about centre bearing issues or replacement when servicing their 2010 Subaru Exiga.

However, for vehicles that are fitted with centre bearings, understanding their purpose and maintenance is still valuable knowledge. Centre bearings play an important role in certain driveline arrangements and keeping them in good condition is key to smooth and reliable vehicle operation.

A centre bearing essentially supports the middle section of a multi-piece driveshaft by absorbing rotational loads and reducing vibrations. It often contains a rubber or elastomeric cushion that dampens vibration and noise, improves driver comfort, and protects the driveline components from excessive wear. It also ensures the driveshaft rotates true and remains stable at various operating angles.

For those vehicles with a centre bearing, regular maintenance or replacement is recommended as part of the driveline service schedule. Over time, the bearing and its rubber mounting can degrade due to factors like exposure to road grime, heat, and mechanical stress. Symptoms of a failing centre bearing may include:

• Driveline vibrations at certain speeds
• Unusual noises such as whining or clunking from underneath the vehicle
• Excessive wear on associated universal joints or driveshaft components

When servicing a vehicle that has a centre bearing, it is important to inspect the bearing itself and check for play or looseness, signs of rust or corrosion, and any cracking or deterioration of the rubber mounting. If a bearing is found to be worn or damaged, it should be promptly replaced to prevent further issues down the line. This involves removing the driveshaft assembly, pressing out the old bearing, and carefully fitting the new one, followed by proper reassembly.

Lubrication also plays a part in the maintenance of related components, even though the centre bearing itself is generally sealed and maintenance-free. Ensuring the universal joints and other driveline elements are well-greased can extend the life of the entire assembly.

In essence, vehicles that do have centre bearings rely on these components for drivetrain smoothness and longevity. For the 2010 Subaru Exiga, this means owners can breathe easy knowing the design avoids the need for this part entirely, reducing servicing concerns. But for anyone working on or maintaining other makes and models, a centre bearing is definitely something to keep an eye on as part of regular driveline care.
