TOYOTA 42450-60070 Rear Right Wheel Bearing Assembly

The genuine OEM TOYOTA 42450-60070 rear right wheel bearing assembly (BEARING ASSY, RR) is a critical suspension component that ensures smooth, minimal-friction wheel rotation while carrying both radial and axial loads generated by vehicle weight and cornering forces. Genuine Toyota parts guarantee precise fitment, maximum safety, and long service life in strict accordance with factory standards.

Technical Characteristics and Specifications

• Fitting Position: Rear axle, right side (passenger side)
• Design: Complete wheel hub assembly (Hub Assembly) integrating both the bearing and hub for simplified installation
• Material Quality: Premium hardened alloy steel engineered for high load-bearing capacity and wear resistance
• Sealing: Equipped with a specialized multi-lip dust and moisture seal to retain internal grease and exclude contaminants
• Lubrication: Factory pre-packed with long-life bearing grease resistant to high temperatures and extreme pressures
• ABS Compatibility: Equipped with an integrated ABS tone ring / magnetic encoder for accurate anti-lock braking system operation

Role and Importance of the Wheel Bearing

The wheel bearing assembly provides a direct, low-friction interface between the rotating wheel and the stationary suspension structure. Its precision rolling elements minimize rolling resistance, directly benefiting fuel economy and driving dynamics. Installing a genuine OEM assembly is essential for ensuring correct calibration and reliable operation of the Electronic Stability Program (ESP) and Anti-lock Braking System (ABS).

Typical Symptoms of Wear and Failure

Wheel bearings operate under constant mechanical stress and harsh environmental conditions (moisture, road salt, abrasive dust). Common signs of failure include:

• Abnormal Noises: Low-frequency humming, growling, or metallic grinding sounds emanating from the wheel, which typically intensify with vehicle speed or during cornering loads.
• Steering Wheel or Body Vibration: Excessive bearing wear may cause wheel instability, transmitting noticeable vibrations through the chassis or steering.
• Excessive Wheel Play: Noticeable looseness or free play when inspecting the elevated wheel by hand.
• ABS Warning Light: If the integrated sensor ring is damaged or excessive runout prevents the sensor from reading the signal correctly, the ABS/ESP warning indicator will illuminate on the instrument cluster.
