Detailed Description

Timken HA594246 is a rear left wheel bearing assembly engineered for 2003-2023 Toyota 4Runner, 2007-2014 Toyota FJ Cruiser, 2003-2009 Lexus GX470, and 2010-2023 Lexus GX460. Timken uses OE-developed testing to control the design, materials, and manufacturing process, helping deliver consistent performance in demanding driveline and axle service. The bearing design supports load capacity, bearing life, and fuel efficiency through precision profiles and enhanced surface finishes, while the integrated ABS sensor is 100% tested to monitor wheel speed for the anti-lock braking system. This part cross-references MOOG Hub Assemblies (e.g., 512227) and SKF (e.g., GRW271) for the same application.

What It Helps Address

• Wheel bearing noise from the rear left side
• Vibration felt through the chassis or steering during road use
• ABS warning concerns related to wheel speed signal issues
• Brake performance changes caused by excessive hub runout
• Wear-related hub bearing service on Toyota 4Runner, FJ Cruiser, Lexus GX470, and Lexus GX460 models

Installation Notes and Tips

Confirm rear left fitment before installation and verify the flange bolt hole count, dimensions, and ABS sensor configuration against the removed part. Clean the mounting surface thoroughly and inspect adjacent driveline and brake components for wear that could affect hub performance. Proper torque procedures and careful handling during installation help protect the seal and sensor surfaces.

Quality Assurance

Timken hub bearing assemblies are manufactured using OE-developed test standards and controlled processes to support consistent fit and performance. The premium seal design and precision bearing construction are used to improve sealing, reduce contamination entry, and extend service life.
