Centre Bearing on the 2018 Mitsubishi ASX: What You Need to Know

The 2018 Mitsubishi ASX, a popular compact SUV, does not actually use a centre bearing in its drivetrain setup. This is largely due to the vehicle's design and the type of drivetrain it employs. The centre bearing is typically found in long driveshaft assemblies on vehicles that have a two-piece driveshaft, which is common in larger vehicles or those with rear-wheel drive and all-wheel drive configurations requiring a long driveshaft to transmit power from the transmission to the rear differential.

In the case of the 2018 Mitsubishi ASX, it is built with a front-wheel-drive layout as standard, though some models come with all-wheel drive. In either configuration, the driveshaft system is quite different from those vehicles that use centre bearings. The ASX's drivetrain features shorter driveshafts connecting the transaxle directly to each front wheel or, in the case of AWD models, to the rear differential through a compact prop shaft. Because of this design, the assembly does not require a long, two-piece driveshaft that would need the centre bearing to support the shaft's middle span.

Basically, the centre bearing acts as a support for the driveshaft, preventing excessive vibration and ensuring the shaft runs straight, especially over the long distances found in larger vehicles. Vehicles with longer wheelbases and higher power outputs often need this extra support. The Mitsubishi ASX, being smaller and using a more compact drivetrain design, avoids the need for this component altogether.

Since the centre bearing is not a relevant part for the 2018 Mitsubishi ASX, owners won't need to worry about this component during regular maintenance or servicing. Instead, the typical wear-and-tear parts dealers and mechanics focus on include the CV joints, driveshaft boots, and universal joints, which are critical for smooth power delivery and vehicle safety.

For the ASX, the front-wheel-drive system means the half-shafts and CV joints are the key areas to monitor. These parts can wear out over time, especially if the protective rubber boots develop cracks or tears. Replacing worn CV joints or boots is standard procedure during servicing, unlike centre bearing replacement, which simply does not apply here.

Other potential issues in the driveline to keep an eye on would be any noises during acceleration or vibrations at highway speeds, which usually point to problems with tyres, wheel alignment, or CV joints rather than centre bearings. Regular inspections by qualified technicians generally cover these points without the need to check for a centre bearing.

For those curious about centre bearings in general, they perform an important role in stabilising long driveshafts. The bearing supports the shaft in the middle, allowing the shaft to rotate smoothly while handling the engine's torque and movement from suspension travel. Over time, centre bearings can wear out, causing vibration, noise, and eventual drivetrain problems. Replacement involves removing the driveshaft, extracting the old bearing, and installing a new one aligned perfectly to prevent further issues. This kind of maintenance is important to keep smooth drivability in vehicles where this component is present.

So, while centre bearings are critical in vehicles with long, two-piece driveshafts, the 2018 Mitsubishi ASX's layout simply makes them unnecessary. Instead, the reliability focus remains on things like CV joints and other front-drive specific components, which are easier and cheaper to maintain - a nice bonus for ASX owners who want a fuss-free SUV for everyday driving.
