Timken HA590538 Wheel Bearing and Hub Assembly - Front

Timken HA590538 Front Hub Assembly

Timken HA590538 is a front wheel bearing and hub assembly built for driven applications that need stable wheel support, accurate ABS signal monitoring, and consistent braking feel. It is engineered for select Nissan NV200, Sentra, and LEAF models, with OE-developed testing used to control design, materials, and manufacturing process.

Key Features

• Front wheel bearing and hub assembly for driven applications
• Low runout helps reduce noise and vibration
• Precision bearing profiles and uniform internal geometry support load capacity and bearing life
• Enhanced surface finishes help improve rolling efficiency
• Premium seal design helps exclude contamination and protect the bearing
• ABS sensor is 100% tested for wheel speed monitoring
• 5-wheel-stud, 4-bolt flange design with 4.500 in. bolt circle diameter
• 30-spline hub configuration

Detailed Description

Timken HA590538 is a wheel bearing and hub assembly designed for front axle service on 2013-2021 Nissan NV200, 2013-2019 Nissan Sentra, and 2013-2017 Nissan LEAF models. The assembly uses a 5-stud wheel mounting pattern, 4 flange bolt holes, a 4.500 in. bolt circle diameter, and a 30-spline driven hub layout. Key dimensions include a 65.89 mm wheel pilot diameter, 67.89 mm brake pilot diameter, 79.93 mm hub pilot diameter, and 40.72 mm flange offset.

Timken applies OE-developed testing to control the design and manufacturing process of its hub bearing assemblies. The bearing design uses precision profiles, uniform internal geometry, and enhanced surface finishes to support load carrying capacity and smooth operation. The seal design includes a reinforced outer case, ribbed rubber inner diameter, internal contamination exclusion features, and vent holes to help protect the seal during installation and extend service life. The integrated ABS sensor is tested to monitor wheel speed for anti-lock braking systems.

This part cross-references SKF BR930872 for the same application.

Common Repair Symptoms

• Wheel bearing noise from the front end
• Excessive wheel play or looseness
• ABS warning light related to wheel speed signal issues
• Brake pulsation or inconsistent braking feel tied to hub runout
• Vibration or humming that increases with vehicle speed

Installation Notes and Tips

• Verify front position and driven hub configuration before installation.
• Inspect the knuckle, axle splines, and mating surfaces for wear or corrosion.
• Clean the hub and brake mounting surfaces to help prevent runout-related noise.
• Confirm ABS connector routing and sensor alignment during installation.
• Torque fasteners to the vehicle manufacturer’s specification.

Quality Assurance

Timken hub assemblies are manufactured using OE-developed test procedures and controlled material and process standards. The bearing, seal, and ABS sensor components are engineered and tested to support consistent performance in service.
