Detailed Description

The Timken HA590370 hub bearing assembly is engineered for rear service on 1992-2001 Toyota Camry, 1992-2001 Lexus ES300, 1995-2004 Toyota Avalon, and 1999-2003 Toyota Solara. Timken applies OE-developed testing to the design, materials, and manufacturing process, helping maintain consistent performance in everyday driving. The bearing uses precision internal geometry and refined surface finishes to support load capacity and bearing life, while the seal design is built to resist contamination and maintain positive sealing. This part cross-references SKF BR930370 and MOOG Hub Assemblies 512310 for the same application.

What It Helps Address

• Rear wheel noise from a worn hub bearing
• Vibration felt through the chassis or seat
• Brake pulsation or inconsistent braking feel related to hub runout
• ABS wheel-speed signal issues caused by a failing hub assembly
• Excessive play or looseness at the rear wheel

Installation Notes and Tips

Verify rear fitment by year, make, and model before ordering. Confirm the 5-lug, 115 mm bolt circle and the rear non-driven application on the vehicle. Inspect the mounting surface, axle area, and brake components for wear or damage before installation, and follow the vehicle service procedure for torque and ABS sensor handling.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test standards to control design, materials, and process. The assembly includes premium seals, precision-profile bearings, and a 100% tested ABS sensor for wheel-speed monitoring.
