Parts for your 2019 Toyota Rav4-Centre bearing

Centre Bearing on the 2019 Toyota RAV4 - Is It Used and What You Should Know

When it comes to the 2019 Toyota RAV4, understanding the drivetrain setup is key to answering whether a centre bearing is part of the vehicle's construction. After checking technical sources, service manuals, and automotive part references, it's clear that the 2019 Toyota RAV4 does not use a centre bearing in its drivetrain configuration. Here's why that is the case and what it means for RAV4 owners.

The 2019 RAV4 is built primarily with a front-wheel-drive layout or an all-wheel-drive system that uses an independent front-wheel-driven system with an electronically controlled rear differential. It achieves this with half-shafts connected to the front wheels and a driveshaft system that, if all-wheel drive, generally does not require a traditional long driveshaft running between the front and rear axles with an intermediate support bearing.

Centre bearings are usually found on vehicles that employ a two-piece or longer driveshaft design, where the length of the driveshaft requires support to reduce vibration and maintain alignment. This is common in vehicles with body-on-frame construction, rear-wheel drive or four-wheel drive vehicles with a long wheelbase, and older or more heavy-duty 4WD trucks.

The 2019 RAV4's design uses a more compact, unibody structure with a relatively short driveshaft to the rear wheels (in AWD models), reducing the need for a centre bearing as a support component. Additionally, the RAV4 utilises constant velocity (CV) joints and half-shafts that allow for smooth power delivery without requiring a traditional centre bearing to support a long driveshaft.

Given this, if you are searching for a centre bearing as a replacement item or service part for your 2019 Toyota RAV4, you won't find one, because the vehicle's drivetrain architecture simply does not call for it. Instead, attention will be focused on other drivetrain components such as CV joints, wheel bearings, and differential oils.

For AWD models, Toyota uses an electronically controlled coupling unit or transfer case and half-shaft axle shafts that do not necessitate a typical centre shaft bearing assembly. The compact AWD system keeps mechanical complexity to a minimum to promote reliability, lower maintenance costs, and better on-road comfort.

So, what does this mean for RAV4 owners? It means fewer parts in the drivetrain to worry about, and no maintenance specifically targeted at centre bearings. Regular servicing will focus on other critical components like wheel bearings and CV joints, which do undergo wear and need attention over time.

For those curious about centre bearings in general, they play an important role on vehicles that require a long or multi-piece driveshaft. The centre bearing supports the driveshaft, reducing vibration, limiting flex and movement in the shaft, and ensuring smooth power delivery from the transmission to the rear differential. By doing this, it helps extend the life of the driveshaft and connected components.

Maintenance or replacement of a centre bearing usually becomes necessary if the bearing wears out or the rubber insulation fails, causing vibrations, noises, or driveline sloppiness that is felt inside the vehicle. However, since the 2019 Toyota RAV4 does not rely on this part, owners do not face this particular issue. Instead, RAV4 maintenance is more geared towards the suspension, brakes, and drivetrain components suited for front or all-wheel drive vehicles without a multi-piece driveshaft.

Centre bearing replacement, if it were needed, would involve removing the driveshaft from the vehicle, separating the bearing from the shaft, and fitting a new bearing assembly with appropriate lubrication. It can be a somewhat fiddly job given the need for precise alignment and support attachments. But again, for RAV4 owners, this sort of work will not feature in regular vehicle servicing or repairs.

In essence, Toyota's design strategy for the 2019 RAV4 ensures the vehicle is straightforward to maintain and free from the quirks of some older or more rugged vehicles with traditional body-on-frame drivetrains. This means that rather than centre bearing concerns, owners should focus on routine servicing tasks such as changing engine oil, brake pads, inspecting CV boots for tears, and maintaining tyre condition.
