Centre Bearing on the 2018 Honda Accord: Is It Relevant?

When talking about the 2018 Honda Accord, one common question that pops up is whether it features a centre bearing or not. The short answer is that the 2018 Honda Accord does not use a centre bearing. This might come as a surprise to some, especially those familiar with vehicles that rely heavily on driveshaft components like centre bearings. But understanding why the Accord doesn't need one starts with a quick look at its drivetrain layout.

The 2018 Honda Accord is a front-wheel-drive vehicle, meaning power is sent directly to the front wheels via the transaxle. Unlike rear-wheel drive or all-wheel drive cars that have a longer driveshaft running from the engine or transmission to the rear wheels, the Accord's layout eliminates the need for a long driveshaft and any associated support components such as a centre bearing. In other words, the powertrain's design simply doesn't require a centre bearing to hold or support a driveshaft.

In many rear-wheel-drive cars and some all-wheel-drive models, a centre bearing is critical. It acts as a support point for the long driveshaft, stabilising it and reducing vibrations. This bearing sits between two shafts, ensuring smooth rotation and improving overall durability of the drivetrain. Because these vehicles have a driveshaft running the length of the car, the centre bearing stops the shaft from flexing or wobbling excessively during operation, which could otherwise cause damage to the drivetrain or even the underside of the vehicle.

Since the 2018 Honda Accord uses a transaxle layout that combines the transmission and differential in the front of the vehicle, it uses shorter half-shafts that connect directly to the front wheels. These half-shafts are substantially shorter and don't require intermediate support. As a result, there is no need for a centre bearing, which would typically be placed mid-length on a full-length driveshaft to support it.

What does this mean for the average Accord owner or mechanic? It means less complexity in the drivetrain, fewer parts to service or replace, and a generally simpler maintenance routine when it comes to the driveline. Owners won't have to worry about the condition or replacement of a centre bearing, because the part isn't even there.

That said, while the Accord doesn't have a centre bearing, it's still important to keep an eye on other components related to the drivetrain like the CV joints, half-shafts, and transmission fluid to ensure that the power is delivered smoothly to the wheels. CV joints can wear out over time, especially if their protective boots become damaged, leading to dirt ingress and eventual failure - something that's more likely to be encountered in front-wheel-drive setups like the Accord's.

So, why is it beneficial for the Accord to avoid using a centre bearing? Mainly because it reduces complexity and potential points of failure. With fewer moving parts, there is less chance for wear and tear, and fewer components to inspect or replace during regular servicing. This contributes to the overall reliability and lower maintenance costs that the Honda Accord is well known for. Additionally, a front-wheel-drive layout tends to be more space-efficient, allowing for more interior room and better fuel economy - which appeals to buyers looking for a practical daily driver.

All in all, while the centre bearing is a vital part in many drivetrains, it simply isn't relevant to the 2018 Honda Accord due to its front-wheel-drive design. For those servicing an Accord, maintenance can focus on other drivetrain elements and routine checks without worrying about the complexity of centre bearing upkeep or replacement.
