Centre Bearing on the 2021 Subaru XV: Is It Used and What You Need to Know

When it comes to the 2021 Subaru XV, many owners and enthusiasts often wonder if this vehicle utilises a centre bearing, especially since it plays a critical role in many all-wheel-drive and rear-wheel-drive vehicles. After a thorough review of technical sources and manufacturer service manuals, it becomes clear that the 2021 Subaru XV does not use a centre bearing in its driveline setup. Understanding why this is the case helps clarify the Subaru XV's driveline design and maintenance requirements.

The Subaru XV (also known as the Crosstrek in some markets) is equipped with a symmetrical all-wheel-drive system that is designed to be compact and efficient. The drivetrain consists of a front transaxle and a rear differential connected by a drive shaft. However, unlike some other AWD or RWD vehicles that employ a longer two-piece driveshaft system requiring a centre bearing to support the intermediate shaft, the Subaru XV utilises a one-piece driveshaft running from the front to the rear differential. As a result, there is no need for a centre bearing to support or stabilise the driveline.

Centre bearings are typically found in vehicles with longer driveshafts where the shaft is split into multiple sections. In those cases, a centre bearing acts as an intermediary support point to reduce vibration, maintain alignment, and carry some of the weight load of the shaft. The Subaru XV's relatively compact build and efficient driveline layout eliminate the need for this sort of setup. The one-piece driveshaft, combined with the vehicle's symmetrical AWD system, means the shaft can run smoothly from front to rear without intermediate supports.

So what does this mean for 2021 Subaru XV owners? Essentially, there is no centre bearing to maintain or replace on this vehicle. This can simplify some aspects of driveshaft maintenance and repair, since centre bearing wear and failure are common points of concern in other AWD and RWD vehicles with longer or multi-piece shafts.

For example, in many vehicles equipped with centre bearings, over time, the rubber isolator or bearing itself can wear out, leading to vibrations, noises, or driveline misalignment. Replacing a centre bearing involves removing the driveshaft, replacing the worn bearing and its mount, and often balancing the shaft again to prevent further issues. Since the Subaru XV does not have one, owners can avoid this particular maintenance headache.

That said, the Subaru XV does still require regular driveshaft and drivetrain inspections as part of routine servicing. This includes checking for any wear or damage on the driveshaft components, universal joints (U-joints), and the rear differential. Even without a centre bearing, these parts are critical to maintain smooth power delivery and avoid drivetrain vibration or failure. If a driveshaft issue does arise on the Subaru XV, it is more likely related to U-joint wear or damage, or an issue with the differential or hub assemblies.

Regular maintenance of the Subaru XV's drivetrain generally includes:

• Visual inspection of the driveshaft for dents, cracks or other damage
• Checking and lubricating U-joints if serviceable (some are sealed and do not require greasing)
• Ensuring that all splash guards and protective covers are in place to shield drivetrain components
• Monitoring for unusual noises or vibrations during driving, which could indicate driveline wear

Considering no centre bearing is fitted, when servicing the Subaru XV, mechanics focus on these components rather than a bearing that does not exist. This also simplifies driveshaft removal and installation because there is no intermediate mounting bracket or bearing to contend with. Overall, the Subaru XV's drivetrain layout is designed to be straightforward and robust, which is part of why the vehicle is popular for reliability and ease of maintenance.

In short, any Subaru XV owner looking to understand their vehicle's driveline should know that while centre bearings are common in other vehicles, they are not relevant to the 2021 Subaru XV. Instead, attention should be directed to the driveshaft shafts, joints, and associated AWD components to keep the car running smoothly. If trouble does arise, such as vibration or noises from the driveline area, a professional inspection will focus on these parts first before considering any less common issues.
