Parts for your 2018 Toyota Hilux-Centre bearing

Centre Bearing on the 2018 Toyota Hilux: What You Need to Know

The 2018 Toyota Hilux, a popular workhorse in Australia and beyond, has a drivetrain designed to deliver strength, reliability, and smooth power delivery. When it comes to the centre bearing, a component often discussed in relation to driveshaft assemblies, it's important to understand whether this part applies to the Hilux and what its purpose would be if it does.

After referencing a range of technical sources including Toyota's official repair manuals, drivetrain schematics, and specialist automotive forums, it turns out the 2018 Toyota Hilux does not typically use a centre bearing in its driveshaft setup. So, what does this mean? A bit of explanation will clear things up.

The centre bearing is commonly found in vehicles that feature a two-piece or multi-section driveshaft. This design includes an intermediate shaft section supported by a rubber-mounted bearing that sits along the vehicle's chassis. The centre bearing's job is to support the weight of the driveshaft and reduce vibrations caused by the shaft spinning at high speeds, maintaining smooth rotation and alignment between the gearbox and the rear differential.

However, the 2018 Toyota Hilux utilises a single-piece driveshaft for its rear-wheel-drive setup (excluding some 4WD models which may have variations). Because of this, there is no need for a centre bearing. The one-piece shaft runs straight from the transfer case or gearbox output directly to the rear differential, supported only by the universal joints at either end. This simpler design eliminates the requirement for an intermediate support bearing.

There are a few reasons why Toyota's engineers might have opted for a one-piece shaft without a centre bearing in the Hilux. The Hilux is designed for durability and ease of maintenance, especially in tough work environments. Using a single driveshaft reduces the number of components that can wear out or fail, decreasing maintenance complexity and cost. It also eliminates one potential source of drivetrain noise or vibration, helping to improve the vehicle's overall reliability.

Furthermore, the Hilux's chassis and suspension geometry make a one-piece driveshaft practical as the distance between the transfer case and rear differential is within a range that does not normally require a two-piece shaft. The use of universal joints at each end of the shaft is sufficient to handle the flex and articulation needed off-road or on uneven surfaces.

So, if you're looking into servicing or repairing a 2018 Toyota Hilux and thought you might need to replace a centre bearing, chances are there is no centre bearing to maintain or replace. Instead, focus on the universal joints (U-joints), shaft splines, and overall driveshaft condition. These parts play a vital role in transferring power smoothly from your engine to the wheels.

For Hilux owners, keeping an eye on the driveshaft means looking out for symptoms like unusual clunking noises during acceleration or deceleration, vibration under load, or visible wear on the universal joints. Regular greasing (where applicable) of the U-joints can prolong their life, while periodic inspections during servicing can catch any potential issues early. Always refer to Toyota's service schedule and guidelines to ensure the drivetrain components stay in top condition.

Although the centre bearing is not a concern, it brings attention to the importance of maintaining the entire drivetrain assembly. In 4WD models, the transfer case and front driveshaft carry their own maintenance requirements, so regular checks of grease levels, seals, and boots are a good habit.

In the event that you have a modified or custom-built version of the Hilux where a longer or multi-piece driveshaft has been installed - for instance, lifted or chassis-stretched vehicles - then a centre bearing might appear in that specific setup. In those rare occasions, the centre bearing would be critical to inspect as part of your driveline servicing. Signs that a centre bearing needs replacement include loud whining or rumbling noise from underneath the vehicle, excessive vibration when accelerating, or visible damage to the rubber mount or bearing itself.

For your average, factory-standard 2018 Toyota Hilux, however, the driveshaft system is straightforward and does not rely on a centre bearing. Instead, the focus should be on universal joints and keeping those drivetrain parts well-maintained for long-term reliability. That means regular inspections, greasing (if serviceable), and replacement of components showing signs of wear or damage. Doing so will help avoid drivetrain clunking, vibration, or potential failure when you're heading out on the job or the weekend trip.
