Parts for your 2018 Honda Cr-v-Centre bearing

Understanding the Centre Bearing and Its Relevance to the 2018 Honda CR-V

The centre bearing, also known as the carrier bearing, is typically found on vehicles with a two-piece drive shaft. Its job is to support the shaft midway, allowing it to spin smoothly and keep vibrations to a minimum while transferring power from the transmission to the rear differential. This bearing plays a crucial role in ensuring the driveline stays balanced and operates quietly.

When it comes to the 2018 Honda CR-V, however, a centre bearing is not relevant or used at all. This is because of the specific drivetrain design employed by this model. The 2018 CR-V uses a single-piece drive shaft for its all-wheel-drive system, which effectively eliminates the need for a centre bearing. Without two separate sections of the drive shaft, there is no midpoint that requires support from a centre bearing. This makes the centre bearing entirely unnecessary.

So why exactly does the 2018 Honda CR-V not use a centre bearing? The key lies in its drivetrain configuration. The drive shaft is designed as a single, continuous piece that runs from the transmission to the rear differential (or from the transaxle for front-wheel-driven versions). Because there is no break or joint in the shaft midway, the issues a centre bearing would normally address - such as shaft flex, vibration, and alignment - are naturally avoided. This simpler drive shaft setup removes the cost and complexity that would come from adding a centre bearing assembly, as well as its associated bearings, mounting brackets, and dust shields.

Many vehicles with two-piece drive shafts feature centre bearings because those shafts need additional support to handle different shaft lengths and angles, especially in rear-wheel-drive or four-wheel-drive vehicles with longer wheelbases. Designers include these bearings to prevent undue wear and vibration, which can lead to premature failure of the driveshaft or other components. But since the 2018 CR-V's drive shaft is compact and straightforward, it relies on robust universal joints and well-engineered shaft materials instead to maintain alignment and reduce vibrations.

This design choice can be beneficial for owners as it typically translates to fewer moving parts that can wear out or require maintenance over time. Centre bearings, after all, can become a source of noise and drivetrain issues if they fail. When they do wear down, they might cause vibrations, clunking noises, or even drivetrain damage if left unattended. In vehicles that use them, centre bearings need inspection during regular servicing schedules and replacement when worn.

Since the 2018 Honda CR-V does not include a centre bearing, owners do not have to worry about this particular part during routine maintenance. Service visits usually focus on other driveline components like the CV joints, universal joints, and the drive shaft's condition itself. Keeping these parts in good shape ensures the vehicle's transmission of power to the wheels remains smooth and reliable.

Still, Honda owners should keep an eye on symptoms like unusual noises coming from underneath the vehicle, vibrations during acceleration, or noticeable play in the drive shaft components. While these signs may not point to centre bearing issues in the CR-V, they can indicate trouble with universal joints or CV joints, which do require attention and possible replacement after significant wear or damage. These components, although different from a centre bearing, play a similarly essential role in power transmission and vehicle stability.

When the drive shaft or universal joints do require service on the 2018 Honda CR-V, it is best to have a qualified technician carry out checks and repairs. They will typically check for joint looseness, inspect the shaft for any signs of damage or wear, and ensure that all components are correctly lubricated to extend their life. Regular maintenance that includes drivetrain inspection can prevent minor issues from turning into expensive repairs down the line.

In short, while a centre bearing serves as an important protective and stabilising element on many vehicles with longer or multi-piece driveshafts, it simply does not feature on the 2018 Honda CR-V due to its single-piece shaft design. This approach reduces complexity and maintenance needs, giving owners one less part to worry about while still ensuring a smooth and dependable driving experience. It pays to understand the drivetrain layout of your vehicle because knowing what parts it has - and doesn't have - can help you focus your attention on the right components during servicing and keep your CR-V running nicely for years to come.
