Timken 512041 Wheel Bearing and Hub Assembly - Rear

Timken 512041 Rear Hub Assembly

Timken 512041 is a rear wheel bearing and hub assembly built for 1998-2003 Toyota Sienna applications. It combines OE-developed testing, precision bearing construction, and integrated ABS sensing to support stable wheel-speed monitoring and consistent road feel.

Key Features

• Rear wheel bearing and hub assembly for non-driven applications
• Fits 1998-2003 Toyota Sienna, rear
• 5 wheel studs with a 4.500-inch bolt circle diameter
• 4 flange bolt holes for direct hub mounting
• Integrated ABS sensor is 100% tested for wheel-speed signal monitoring
• Low runout construction helps reduce noise and vibration
• Premium seals and precision bearing surfaces support longer service life

Detailed Description

Timken 512041 is engineered for rear axle service on the Toyota Sienna, with dimensions that matter for proper fit and function: a 60.00 mm wheel pilot diameter, 62.00 mm brake pilot diameter, 83.88 mm hub pilot diameter, 153.00 mm flange diameter, and 78.60 mm flange offset. The assembly uses premium bearings with uniform internal geometry and enhanced surface finishes to support load capacity and efficient operation. Timken hub assemblies are manufactured using OE-developed testing methods that control design, materials, and process consistency. This part cross-references MOOG Hub Assemblies (e.g., 512041) for the same application.

What It Helps Address

• Rear wheel bearing noise on a 1998-2003 Toyota Sienna
• Wheel vibration caused by hub runout
• ABS warning concerns related to wheel-speed signal issues
• Uneven braking feel from worn hub components
• Loose or rough rear hub operation

Installation Notes and Tips

Confirm rear fitment by matching the vehicle year, position, bolt circle, pilot diameters, and flange dimensions before installation. Inspect the mating surfaces, axle area, and ABS wiring or connector condition during replacement. Because this is a non-driven rear hub assembly, verify that the application matches the rear position on the Toyota Sienna before ordering. Timken 512041 should be installed with proper torque procedures and clean mounting surfaces to help maintain bearing alignment.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. Premium seals, precision bearing profiles, and tested ABS sensor performance are part of the product design for consistent operation in service.
