Centre Bearing on the 2016 Toyota Hiace: Is It Used and What You Need to Know

When it comes to the 2016 Toyota Hiace, many people wonder if a centre bearing is a part of its drivetrain setup. After checking technical manuals and vehicle specifications, it turns out the 2016 Toyota Hiace does not use a centre bearing in its driveline system. Here's why that's the case and what it means for the vehicle's maintenance and driveability.

The 2016 Toyota Hiace typically features a single-piece driveshaft, often referred to as a one-piece or solid shaft. It connects the transmission directly to the rear differential without an intermediate support. In vehicles with longer driveshafts that have multiple sections, a centre bearing is used to support the shaft where it is joined, preventing excessive vibration and load on the drivetrain components. However, since the Hiace's driveshaft is a single piece in this generation, it simply doesn't require a centre bearing.

This design choice can be understood by considering the vehicle's dimensions and the engineering goals Toyota set for the Hiace. The Hiace is built as a light commercial van with a relatively short wheelbase compared to larger trucks or SUVs that often feature multi-piece driveshafts. By using a solid driveshaft, Toyota keeps the drivetrain simpler and potentially more robust. Without joints or intermediate bearings, there are fewer parts to wear out or fail, reducing maintenance complexity and cost.

Furthermore, not using a centre bearing eliminates possible points of vibration and noise commonly associated with bearing wear. It keeps the ride smooth and stable, especially important for a vehicle intended for carrying passengers or loads. The solid shaft's simple design also means less likelihood of drivetrain misalignment, a common cause of premature wear in vehicles with multi-piece shafts and centre bearing assemblies.

So even though this Hiace generation doesn't use a centre bearing, understanding what a centre bearing does can still be useful if you're dealing with other vehicles or future models that may have different driveline designs.

For vehicles that do have a centre bearing, this little part plays a vital role in keeping the driveshaft assembly running smoothly. A centre bearing supports the driveshaft exactly where it splits into two pieces. This support stops the shaft from flexing or bouncing excessively while the vehicle is moving, especially at higher speeds or under load.

The bearing itself usually consists of a rubber or polyurethane mount with a steel bearing inside that allows the shaft to spin freely while being held securely in position. Without this support, the driveshaft could wobble, vibrate, or even come loose, which would lead to uncomfortable ride quality and potential damage to other components like the transmission or differential.

For those fortunate enough to own a vehicle equipped with a centre bearing, maintenance and replacement are important considerations. Over time, the rubber mounting on the bearing can crack, dry out, or wear due to heat and road conditions. If the bearing starts to fail, it is often noticeable as a rumbling noise underneath the vehicle or increased vibration felt through the floor or pedals. Ignoring these signs can eventually cause driveline damage and expensive repairs.

Replacing a centre bearing is usually a straightforward job for a skilled mechanic. The process typically involves removing the driveshaft, pressing out the old bearing, and installing a new one. In some cases, the entire assembly may need replacement if other parts are damaged.

Regular checks should be part of routine servicing, especially for vehicles that do a lot of towing or heavy use. Ensuring the centre bearing and associated parts like the driveshaft joints remain in good condition helps preserve the overall health of the drivetrain, keeping the vehicle running smoothly and safely.

Though the 2016 Toyota Hiace does not have this component, understanding the centre bearing's function can help drivers appreciate the design choices that go into different vehicles and their driveline configurations. For the Hiace, the absence of a centre bearing means fewer parts to worry about and a simpler, more durable drivetrain setup that suits the van's needs perfectly.
