Timken HA590348 Wheel Bearing and Hub Assembly - Front or Rear

Timken Hub Bearing Assembly for CTS and Camaro

Timken HA590348 is a wheel bearing and hub assembly built for select rear and front applications on the Cadillac CTS and Chevrolet Camaro. It is engineered around OE-developed testing and precision manufacturing controls to support smooth wheel rotation, stable braking feel, and consistent ABS wheel-speed signal performance.

Key Features

• Wheel bearing and hub assembly for driven applications
• Low runout design to reduce noise and vibration
• Premium seals with reinforced construction and contamination control features
• Precision-profile bearings with uniform internal geometry and enhanced surface finishes
• ABS sensor testing for reliable wheel-speed monitoring
• 33 spline count, 5 wheel studs, and 3 flange bolt holes
• 4.724 in. bolt circle diameter and 6.181 in. flange diameter

Detailed Description

Timken HA590348 is a direct-fit hub bearing assembly for select 2009-2016 Cadillac CTS models and 2010-2015 Chevrolet Camaro models, including rear applications for Performance Package and Non Performance Package A1Y configurations. It also fits front applications on select CTS and Camaro vehicles. The assembly uses precision bearing geometry and refined surface finishes to support load capacity, bearing life, and rotational efficiency, while the sealed design helps limit contamination and maintain consistent operation. If you are replacing a worn Cadillac CTS wheel hub assembly or a Chevrolet Camaro rear hub bearing, Timken HA590348 provides the fitment and dimensional specifications needed for the application.

This part cross-references SKF BR930555 for the same application.

What It Helps Address

• Wheel bearing noise or growling from the hub area
• Steering or braking vibration related to hub runout
• ABS warning concerns caused by wheel-speed signal issues
• Loose, rough, or uneven wheel rotation
• Reduced braking consistency from worn hub components

Installation Notes and Tips

Verify the vehicle position, drive type, spline count, bolt circle diameter, and flange dimensions before installation. Confirm whether the vehicle is a front or rear application and check the Camaro rear configuration notes for Performance Package or Non Performance Package A1Y coverage. Inspect the mating surfaces, axle interface, and ABS connector condition during replacement to help ensure proper seating and signal operation. For best results, compare the old unit to Timken HA590348 before installation.

Quality Assurance

Timken manufactures this hub assembly using OE-developed test procedures that control design, materials, and production processes. The result is a hub bearing assembly built to maintain consistent performance, with premium seals, precision bearings, and tested ABS sensor functionality.
