Understanding the Centre Bearing and Its Role in the 2022 Toyota Camry

For most drivers and car enthusiasts, the centre bearing might not be the first thing that comes to mind when thinking about a vehicle's driveline components. When it comes to the 2022 Toyota Camry, especially the models available in the Australian market, a closer look at technical sources such as Toyota's service manuals and automotive engineering references reveals that a centre bearing is not fitted or necessary on this vehicle. This absence is based on fundamental design choices made by Toyota for the Camry's driveline configuration.

The 2022 Toyota Camry primarily features a front-wheel-drive system in its standard and hybrid variants. In front-wheel-drive vehicles, power from the engine and transmission is delivered directly to the front wheels via constant velocity (CV) joints and half-shafts. Because the driveshafts on these cars are relatively short and do not require an intermediate support, there is simply no place or role for a centre bearing. The centre bearing is typically used to support a long, two-piece driveshaft that delivers power to the rear wheels or to the rear differential on rear-wheel or all-wheel-drive vehicles.

For example, in rear-wheel-drive or all-wheel-drive cars with a long driveshaft running from the transmission or transfer case to the rear differential, the driveshaft is often split into two sections for strength, balance and reliability. Here is where the centre bearing comes in. Mounted to the vehicle's chassis, it supports the middle section of the driveshaft, preventing excessive vibration and wear by holding the shaft in place while allowing it to rotate freely. But since the 2022 Toyota Camry's front-wheel-drive system does not include such a shaft, it, therefore, does not utilise a centre bearing.

Even the Camry models fitted with an all-wheel-drive option (available in some regions from the 2021 model year onwards) use systems designed with more compact drivetrain layouts or driveshafts where centre bearings are not required. Instead, these drivetrains use shorter shafts connecting the transfer case and the rear wheels with fewer components that demand intermediate support.

So, why is a centre bearing relevant at all, and what makes it important in vehicles that actually have one? When a vehicle has a long driveshaft, the centre bearing plays a crucial role in maintaining smooth rotation and reducing wear on the driveshaft assembly as well as the related universal joints. It acts as a mid-support that prevents unwanted movement or flex of the driveshaft, which can otherwise lead to vibrations felt inside the vehicle or premature failure of driveshaft components. A failing centre bearing may produce clunking or humming noises from underneath the car, and if left unattended, it can cause damage to other drivetrain parts, leading to costly repairs down the track.

For vehicles that do have a centre bearing, replacing or maintaining this component is an essential part of driveline upkeep. Since the centre bearing carries the rotational load of the driveshaft and keeps it properly aligned, its condition is critical to safe and comfortable driving. Over time, the rubber insulator of the bearing may deteriorate due to exposure to road debris, moisture, heat and vibration, leading to wear or outright failure. Regular inspections of the driveline, including checking for excessive play in the shaft or unusual noises during acceleration or deceleration, can help detect centre bearing issues early.

Replacement usually involves removing the driveshaft assembly, dismounting the old centre bearing and fitting a new one. It is advisable that this job be done by professional technicians equipped with the right tools and experience to ensure proper alignment and balance of the driveshaft afterwards. Driving with a faulty centre bearing can cause vibrations that not only affect comfort but also accelerate wear on other drivetrain components, including the transmission and differential.

Ultimately, while the 2022 Toyota Camry does not require a centre bearing due to its drivetrain design, understanding this component remains valuable for anyone interested in automotive driveline systems. The Camry's reliance on front-wheel drive or compact AWD systems means it sidesteps the need for the additional support a centre bearing provides, allowing for simpler, lighter and more efficient power delivery setups. For Camry owners, taking care of other key service items like CV joints, transmission fluid, and differential oil is where the maintenance focus should stay to ensure peak driveline performance.
