Detailed Description

Timken HA590040 uses OE-developed testing methods to control the design, materials, and manufacturing process of the hub bearing assembly. The result is a rear hub assembly built to maintain precise wheel support, reduce runout, and help limit noise and vibration during braking and driving. Premium bearing profiles, uniform internal geometry, and refined surface finishes are used to support load capacity, bearing life, and fuel efficiency. Premium seals add contamination exclusion features and venting details to help protect the assembly during installation and service. This part cross-references SKF BR930324 for the same application.

What It Helps Address

• Rear wheel bearing noise or humming
• Wheel vibration caused by excessive hub runout
• ABS warning concerns related to wheel-speed signal issues
• Brake pulsation or inconsistent braking feel from worn hub support
• Loose or rough rear wheel bearing operation
