Universal Joints and the 2012 Suzuki Splash: What You Need to Know

When it comes to the 2012 Suzuki Splash, universal joints are not part of the drivetrain setup. This might come as a surprise to some automotive enthusiasts who are familiar with universal joints being common in many vehicles, especially those with rear-wheel drive or four-wheel drive configurations. However, the Splash is a front-wheel-drive hatchback, which fundamentally changes the way power is delivered to the wheels and the components involved.

Universal joints, or U-joints, are typically used in vehicles with a driveshaft that transmits torque from the transmission to the rear differential or from one part of the drivetrain to another. They allow for flex and variation in angle between connected shaft components, which is crucial in rear-wheel drive and some four-wheel drive systems because the driveshaft moves and angles around suspension and chassis components. Because the 2012 Suzuki Splash uses a transversely mounted engine paired with a front-wheel-drive configuration, there is no long driveshaft running down the length of the vehicle where universal joints would be necessary.

Instead of universal joints, the front-wheel-drive system in the Suzuki Splash relies on constant velocity joints, or CV joints. CV joints are designed to maintain a constant rotational speed regardless of the angle of the drive shaft, which is essential for front wheels that steer and move up and down with suspension travel. CV joints are located at both ends of the half-shafts connecting the transaxle to the driving wheels, enabling smooth power transfer even when the wheels turn or bounce on uneven roads.

So why doesn't the Suzuki Splash use universal joints? The key lies in the vehicle's layout and design philosophy. Front-wheel-drive cars like the Splash have all the major drivetrain components located upfront, integrating the transmission and differential into a single transaxle. This compact setup eliminates the need for a long driveshaft and the universal joints that come with it. Instead, using CV joints allows the vehicle to be lighter, more efficient, and simpler to manufacture and maintain.

Since universal joints are not found on the 2012 Suzuki Splash, servicing and maintenance tips relating specifically to universal joints won't apply here. Instead, what should be focused on are the CV joints and the associated components such as the CV boots. These boots are vital for keeping grease inside the joint and preventing dirt, water, and contaminants from entering the CV joint, which could lead to premature wear and eventual failure.

In vehicles that do have universal joints, these components play a really vital role in enabling the drivetrain to flex while still transmitting power smoothly. U-joints typically appear in pairs on a driveshaft and can wear out over time due to the constant flexing and harsh conditions underneath the car. When a universal joint starts to fail, symptoms often include clicking noises, vibration during acceleration, and visible wear or play when you manually move the driveshaft.

Replacing universal joints involves removing the driveshaft, pressing out the worn joints, and pressing in new ones. It's a job that requires some mechanical skill and the right tools. Regular inspection as part of a vehicle's routine service can catch wear early, preventing more serious damage and costly repairs down the track. Greasing the U-joints (if they are of a greasable type) keeps them running smoothly and extends their life.

For owners of the 2012 Suzuki Splash, the focus for driveline maintenance should be on checking and caring for the CV joints and boots. If a torn CV boot is spotted, it's best to address it quickly to avoid losing the grease and letting harmful debris in. Replacement of CV boots or CV joints should be carried out by a qualified mechanic if you notice clicking while turning, vibrations, or worn/damaged boots. Regular servicing as recommended in the vehicle's handbook is your best defence for keeping everything in good shape.

While universal joints have their place in many car drivetrains, the 2012 Suzuki Splash's front-wheel-drive layout means these particular components are simply unnecessary. Instead, the focus shifts to the CV joints that deliver power to the front wheels while allowing for smooth steering and suspension movement. Keeping these CV joints in good order ensures the little Splash runs reliably and quietly for years to come.
