Parts for your 2018 Ford Fiesta-Cv joint

Understanding the CV Joint on the 2018 Ford Fiesta

The 2018 Ford Fiesta is a popular hatchback that blends style, efficiency and dependable performance. One of the key components that help deliver smooth power from the engine to the wheels is the constant velocity joint, commonly known as the CV joint. For those who might not be familiar with this part, the CV joint plays a crucial role in the car's drivetrain, especially on front-wheel drive vehicles such as the 2018 Fiesta.

The CV joint is a specialised coupling that connects the transmission to the drive wheels, allowing for the transfer of torque at a constant speed while accommodating the up-and-down motion of the suspension and the steering changes. This is important because as the Fiesta corners or travels over bumps, the wheels move and steer independently of the engine. Without a CV joint, this movement would make it impossible for power to be delivered smoothly and effectively. Essentially, the CV joint ensures that the front wheels receive power regardless of angle or suspension movement, maintaining continuous driving force without binding or vibration.

In the 2018 Ford Fiesta, the CV joint is found within the drive shafts, which link the transaxle to the front wheels. The Fiesta, being a front-wheel drive car, relies heavily on these joints for everyday driving. The front axle shafts typically have two CV joints each - an inner one near the transmission and an outer one near the wheel hub. The outer joint, usually a Rzeppa joint, allows for higher range of steering angles, while the inner joint handles changes in axle length due to suspension movement.

Running on a mix of city roads and open highways, the CV joints on a Ford Fiesta endure constant movement, exposure to the elements, and lots of torque transfer. That's why regular inspection and maintenance of these joints are critical for the car's reliability and safety. A common point of failure is the rubber CV boot that encases the joint, protecting it from dirt, water and debris while containing grease to keep the joint lubricated. If the boot cracks or tears, grease escapes and contaminants get inside, causing accelerated wear and eventual joint failure.

When the CV joint starts to fail, Ford Fiesta drivers might notice some typical symptoms such as clicking or popping noises when turning, especially at lower speeds, or a noticeable vibration under acceleration. Sometimes grease splatters around the wheel well are a giveaway that the boot has been compromised. Ignoring these signs can lead to more severe damage, potentially leaving the vehicle undrivable and leading to a costly replacement of the entire drive shaft.

Replacing or servicing CV joints on the 2018 Ford Fiesta should ideally be part of routine maintenance, especially for those who regularly tackle rough roads or high mileage. During servicing, mechanics will inspect the CV boots for cracks or tears, check for grease leaks and listen for unusual noises. Where damage is found, replacing the boots quickly can sometimes salvage the joint itself, but often it's more practical and reliable to replace the entire axle shaft assembly, as this ensures new joints and proper balance.

Costs for CV joint replacement can vary, but given the Fiesta's reputation for affordability and ease of maintenance, finding genuine or aftermarket parts is relatively straightforward in Australia. Skilled mechanics will also make sure the axle shafts are balanced and aligned correctly to avoid vibrations or uneven tyre wear.

Taking care of the CV joints not only extends the life of the drivetrain but also keeps driving enjoyable and safe. Smooth steering, responsive handling and quiet operation all benefit from well-maintained CV joints. Ford Fiesta owners should consider having their joints checked every 40,000 to 60,000 kilometres or during major services, and sooner if driving conditions are particularly tough.

In all, the CV joint is a silent hero under the tray of the 2018 Ford Fiesta. It quietly does the hard work of allowing the front wheels to turn and move while still getting power from the engine. Treating this component with a bit of attention and care during servicing helps keep one of Australia's favourite small cars running happily for years.
