Centre-Bearing on the 2019 Lexus IS - Is It Used and What You Should Know

When it comes to the drivetrain of the 2019 Lexus IS, one common question that pops up is whether this model uses a centre-bearing. A centre-bearing is a component typically found in vehicles with a two-piece driveshaft setup, designed to support the driveshaft and reduce vibrations as power is transmitted from the engine to the wheels. But does the 2019 Lexus IS need a centre-bearing? The short answer is no, and here's why.

The 2019 Lexus IS, depending on the specific variant and drivetrain layout, is mainly equipped with a rear-wheel-drive or all-wheel-drive system featuring a single-piece driveshaft. This design choice means there is no need for a centre-bearing. Centre-bearings are usually found on vehicles with longer, two-piece driveshafts commonly used in trucks, large SUVs, or some rear-wheel-drive cars with a longer wheelbase where the driveshaft length surpasses what a single piece can handle without excessive wobble or stress.

In the case of the 2019 Lexus IS, the driveshaft connecting the transmission to the differential is one continuous piece, which negates the requirement for a centre-bearing. This simplifies the drivetrain, reducing the number of components that could fail or require maintenance. Additionally, the IS's relatively compact size and drivetrain layout keep the driveshaft short enough to avoid the issues that centre-bearings are designed to address.

With no centre-bearing to worry about, owners of the 2019 Lexus IS benefit from a drivetrain that is inherently less complex and usually more reliable over time. The elimination of the centre-bearing reduces potential wear points and eliminates the chance of centre-bearing noise, vibration, or failure.

So, what should owners focus on when it comes to maintaining the drivetrain of a 2019 Lexus IS? It's important to keep an eye on the more conventional parts that do require attention such as the universal joints (U-joints), the driveshaft itself, and other transmission-related components. Regular servicing of these parts ensures smooth operation and longevity.

While the centre-bearing isn't part of the 2019 Lexus IS setup, knowing what it does in other vehicles helps understand its role. In cars that do use a centre-bearing, it acts as a middle support for the two-piece driveshaft assembly. This bearing absorbs and reduces vibrations, helps balance the driveshaft, and supports the shaft to prevent flexing or bending during rotation. Essentially, it makes driving smoother and protects other drivetrain components from damage caused by excessive vibration or misalignment.

When centre-bearings do need replacement, common signs include a loud rumbling noise coming from under the car that gets worse with speed, noticeable vibrations through the floor or seats, or visible play if inspected. Neglecting these symptoms can lead to further wear on the driveshaft or even more serious transmission damage.

For vehicles that have a centre-bearing, maintenance usually involves inspection during servicing, especially if vibration symptoms are present. Replacement is normally a straightforward job performed by experienced mechanics. They remove the driveshaft, replace the worn bearing, and reinstall the shaft with proper balancing. After that, drivers often notice a significant reduction in vibration and noise.

But since the 2019 Lexus IS does not come with a centre-bearing, none of these issues apply directly. Instead, IS owners should focus on other drivetrain and suspension components during regular maintenance intervals. It's wise to follow the manufacturer's servicing schedule to keep everything in top shape, especially as the Lexus IS continues to deliver that smooth and responsive performance drivers expect.

In short, the absence of a centre-bearing on the 2019 Lexus IS makes for a simpler drivetrain and less maintenance hassle in that particular area. Drivers can enjoy the luxury, performance, and reliability of their Lexus IS without worrying about this specific part.
