Parts for your 2021 Suzuki Splash-Centre bearing

Understanding the Centre Bearing on the 2021 Suzuki Splash

When it comes to the drivetrain components of the 2021 Suzuki Splash, a common question is whether this compact hatchback actually uses a centre bearing. From a technical standpoint, the 2021 Suzuki Splash does not feature a centre bearing in its drivetrain setup. This is largely due to the vehicle's front-wheel-drive configuration and relatively short driveshaft lengths, which eliminate the need for a centre bearing.

How come the centre bearing is not relevant for the Suzuki Splash? The centre bearing, also known as an intermediate or carrier bearing, is typically used in vehicles with long driveshafts - often those with rear-wheel-drive, all-wheel-drive or four-wheel-drive systems that have a two-piece driveshaft. This bearing supports the driveshaft at the midpoint, helping to reduce vibrations and allow the shaft to spin smoothly with proper alignment. Since the Suzuki Splash is a front-wheel-drive car, it employs shorter half-shafts (CV axles) directly transferring power from the transaxle to the front wheels. These shorter shafts don't require a centre bearing for support.

Vehicles with shorter single-piece driveshafts or CV axles simply don't need that extra support in the middle because the component dimensions and layout keep them stable on their own. The 2021 Suzuki Splash's design embraces this simpler drivetrain architecture, which contributes to its compactness, lower weight, and overall cost efficiency.

For those curious about maintenance and servicing, since there is no centre bearing on the 2021 Suzuki Splash, this part does not require any checks, replacement, or specialised attention. Instead, the focus should be on the CV joints and axle boots, which are the critical components in front-wheel-drive half-shafts. Those boots protect the joints from dirt and damage, and once they wear out or split, grease leaks can lead to joint failure.

That said, for vehicles that do have a centre bearing, it is important to know what role it plays and how to maintain it. A centre bearing helps manage the rotational loading on a two-piece driveshaft. Without it, vibrations and premature wear could develop due to improper shaft alignment or excessive shaft flex. It essentially acts as a stabiliser, keeping the driveshaft properly positioned and reducing stress on the transmission and differential.

When maintaining or servicing a centre bearing, technicians will usually inspect for signs of wear such as noise, vibration or movement in the bearing assembly. A failing centre bearing can cause a noticeable humming or rumbling noise that changes with engine speed or vehicle speed. If left unaddressed, it can lead to more costly damage to the driveshaft or surrounding components.

Replacing a centre bearing typically involves removing the driveshaft to gain access. This can be time-consuming, especially if the bearing is pressed tightly or if there are any corrosion issues. It's important to use quality replacement parts and to apply appropriate lubrication or thread-locking compounds when reinstalling. Getting the driveshaft balanced after replacement is also recommended to avoid further vibrations.

Servicing intervals for centre bearings generally align with overall drivetrain inspections or when symptoms arise. Regular checks on vibration and noise during routine servicing can help catch potential issues early, ensuring the driveshaft remains trouble-free and the vehicle runs smoothly.

While the 2021 Suzuki Splash doesn't need a centre bearing, understanding its purpose is handy if you ever work on or drive vehicles with more complex drivetrains. For the Splash, just keep an eye on those CV boots and joints, and your front-wheel-drive system will stay happy with minimal fuss.
