Timken HA590398 Wheel Bearing and Hub Assembly - Front

Timken HA590398 Front Hub Assembly

Timken HA590398 is a front wheel bearing and hub assembly for select Jaguar models, including the XJ, XF, XFR, XK, XKR, XJR, XJR575, and XKR-S. Built for non-driven front applications, it is engineered to support smooth wheel rotation, stable braking, and consistent ABS wheel-speed signal performance.

Key Features

• Front wheel bearing and hub assembly for non-driven applications
• OE-developed testing used in the design, materials, and manufacturing process
• Low runout construction to reduce noise and vibration
• Premium seals with reinforced outer case, ribbed inner diameter, contamination exclusion system, and vent holes
• Precision-profile bearings with uniform internal geometry and enhanced surface finishes
• ABS sensor is 100% tested for wheel-speed monitoring
• Timken part number HA590398

Detailed Description

Timken HA590398 is built as a direct-fit front hub assembly for Jaguar vehicles that require a non-driven wheel bearing and hub unit. It uses OE-developed validation methods to control design, materials, and production, helping maintain consistent fit and performance. The bearing design focuses on low runout, which supports quieter operation, reduced vibration, and more stable braking feel. Precision bearing geometry and refined surface finishes are used to improve load handling and bearing durability. The integrated ABS sensor is tested to monitor wheel speed for anti-lock braking systems, making this assembly a practical choice for Jaguar XJ, XF, XFR, XK, XKR, XJR, XJR575, and XKR-S front-end service. This part number, HA590398, is also referenced by SKF BR930687 and MOOG 512371 for the same application.

What It Helps Fix

• Wheel bearing noise from the front hub area
• Steering wheel or chassis vibration related to hub runout
• ABS warning light concerns tied to wheel-speed signal issues
• Uneven braking feel caused by worn hub components
• Excessive play or rough rotation in the front wheel bearing assembly

Installation Notes and Tips

Verify front-position fitment before installation and confirm the hub dimensions against the original part. This assembly is for non-driven front applications, so drivetrain configuration should be checked during diagnosis. Inspect the mating surfaces, axle area, and brake components for wear or contamination before mounting the new hub. After installation, clear any stored ABS codes and road test the vehicle to confirm proper wheel-speed signal operation.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The design includes premium seals, precision bearing profiles, and tested ABS sensor functionality to support consistent performance in service.
