Driveshafts on the 2018 Honda Civic: What You Need to Know

The 2018 Honda Civic is a popular car in Australia known for its reliability, fuel efficiency and smooth drive. When it comes to understanding the drivetrain of this vehicle, it's important to know whether driveshafts play a role or not. Driveshafts are commonly found in many vehicles but whether they are relevant to a specific model comes down to the layout of its transmission system. So, are driveshafts used on the 2018 Honda Civic? Let's clear that up first.

The 2018 Honda Civic primarily features a front-wheel-drive (FWD) layout. This means that the engine's power is sent directly to the front wheels through a transaxle that combines the transmission and differential into one unit. Because of this, the Civic does not use a traditional long driveshaft like rear-wheel-drive vehicles or some all-wheel-drive setups would.

Instead, the front wheels are driven by shorter constant velocity (CV) axles that connect the transaxle to the wheels. These CV axles perform a similar job on the front end by transferring torque, but they are much different in construction and length compared to the driveshafts found in rear or four-wheel drive cars. So technically, the 2018 Honda Civic does not have the traditional driveshaft you might think of when you refer to this part.

Why doesn't the 2018 Civic use driveshafts? It's all about the vehicle's front-wheel-drive layout. In FWD setups, the engine and transmission sit transversely (sideways) in the engine bay, and power is routed to the front wheels without the need for a long driveshaft running along the vehicle's length. This design offers more efficient packaging, better interior space and generally lighter weight compared to having a driveshaft along the car's tunnel.

As for the driveshaft itself, this component is crucial in vehicles with rear-wheel drive or all-wheel drive because it transfers torque from the transmission, which is usually at the front of the car, to the rear differential or other driven wheels. A driveshaft has to be strong and balanced to handle the rotational forces at varying speeds. It is typically a long metal tube with universal joints at both ends that allow for movement when the suspension travels up and down.

When a driveshaft is fitted, it's a vital part to maintain for smooth and safe driving. Common signs of a failing driveshaft include vibrations while driving, knocking noises underneath the car, or difficulty turning smoothly. If left unchecked, issues with the driveshaft can lead to drivetrain damage or even a breakdown, so keeping an eye on this component during regular servicing is key for many vehicles.

Though the 2018 Honda Civic might not have traditional driveshafts, it does rely on CV axles instead and these need attention as part of the car's drivetrain maintenance. The CV axles have specialised joints covered in rubber boots. These boots protect the joints from dirt, moisture and debris, which can cause wear if the boots crack or tear. Regular servicing involves checking these CV boots for damage and ensuring there's no grease leakage. If the joint is damaged, replacing the whole CV axle is necessary to avoid wheel lock or drivetrain failure.

When servicing the 2018 Civic, mechanics focus on the health of the transaxle and CV axles rather than a traditional driveshaft. However, if you owned a different Honda model with all-wheel drive or rear-wheel drive, you might find driveshafts requiring lubrication, balancing or replacement over time, depending on mileage and driving conditions.

For owners of the 2018 Honda Civic, regular servicing at reputable workshops will typically cover inspection of the CV boots and axles to ensure everything is in top shape. This usually aligns with standard service intervals based on kilometres driven or time. Servicing your car on time helps catch any rubber boot damage early and avoid more costly repairs down the track.

In a nutshell, if you're looking into driveshafts on the 2018 Honda Civic, it's best to understand that this particular model doesn't rely on them due to its front-wheel-drive design. Instead, similar parts like CV axles handle the drivetrain's power transfer to the front wheels and should be the focus when thinking about maintenance related to your car's drive components. Keeping those CV axles in good working order will ensure the Civic continues to provide that smooth, reliable driving experience Australian drivers appreciate.
