Product Overview

The wheel hub bearing assembly, OEM number 42450-0E120, is the rear hub fitted to the Toyota Grand Highlander, 2024 model year, covering the 2.4L (without hybrid) and 2.5L FWD variants. This is a current-generation Toyota SUV, and since the Grand Highlander is a newer addition to Toyota's lineup with growing sales volume, it's a part worth adding to inventory as more of these vehicles reach the age where wheel bearing wear becomes relevant.

Worn units typically show up as a humming or grinding noise from the rear wheel that changes with vehicle speed, vibration felt through the vehicle, or an ABS or traction control warning light. GSK Auto manufactures this hub assembly to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this hub includes the ABS wheel speed sensor and is specific to FWD, non-hybrid variants, so it's worth double-checking drivetrain and hybrid status before ordering at volume.)

What Is a Wheel Hub Bearing Assembly?

Function: The wheel hub bearing assembly supports the wheel, allows it to rotate freely with minimal friction, and carries the vehicle's weight at that corner while also serving as the mounting point for the brake disc, wheel, and ABS wheel speed sensor.

Working Principle: Sealed bearings inside the hub allow smooth rotation under load while resisting both radial and axial forces from cornering, braking, and road impacts, keeping the wheel running true, with the integrated ABS sensor monitoring wheel speed for the vehicle's braking and traction control systems.

Importance: Because the ABS wheel speed sensor is built into this hub assembly, a failing bearing can affect both ride quality and the accuracy of the vehicle's ABS and traction control systems.

Common Failures & Signs: Humming, growling, or grinding noise from the wheel that changes with speed. Vibration felt through the vehicle, particularly at highway speeds. ABS or traction control warning light triggered by a wheel speed sensor issue tied to the hub. Looseness or play felt when the wheel is rocked by hand.
