Timken HA590515 Front Hub Assembly

Timken HA590515 is a front wheel bearing and hub assembly for select Ram 1500 and Ram 1500 Classic applications. It is built with OE-developed testing and precision manufacturing controls to support consistent wheel-end performance, reduced noise, and stable braking feel.

Key Features

• Front driven hub assembly for select Ram 1500 and Ram 1500 Classic models
• 33-spline design with 5 wheel studs and a 3-bolt flange pattern
• 5.500-inch bolt circle diameter for the listed applications
• Low runout construction helps reduce wheel-end noise and vibration
• Premium seals use reinforced materials and contamination control features
• Precision bearing profiles and enhanced surface finishes support load capacity and bearing life
• ABS sensor is 100% tested for wheel speed monitoring in Anti-lock Braking Systems

Detailed Description

Timken HA590515 is engineered as a front hub bearing assembly for 2012-2018 Ram 1500 and 2019-2022 Ram 1500 Classic front applications, including 2012 Ram 1500 front non-heavy-duty use. The assembly uses a driven hub design with a 3.545-inch hub pilot diameter, 3.060-inch wheel pilot diameter, 3.089-inch brake pilot diameter, and 1.841-inch flange offset. These dimensions support proper wheel-end alignment and fitment on the listed Ram truck platforms. Timken HA590515 also cross-references MOOG Hub Assemblies 515151 and SKF BR930858 for the same application.

Timken applies OE-developed testing to the design, materials, and manufacturing process of this hub assembly. The result is a wheel bearing and hub unit focused on controlled runout, stable ABS signal performance, and durable sealing for everyday truck use. If you are replacing a worn front hub on a Ram 1500 or Ram 1500 Classic, this part number provides a direct match to the specified fitment.

What It Helps Fix

• Front wheel bearing noise or growling
• Wheel vibration caused by hub runout
• ABS warning light concerns related to wheel speed signal issues
• Loose or unstable front wheel-end feel
• Uneven braking performance linked to hub wear

Installation Notes and Tips

Verify the vehicle’s year, model, and front axle configuration before installation. Confirm the 33-spline driven hub design, 5-bolt wheel pattern, and listed pilot dimensions match the original part. Clean the mounting surface thoroughly and inspect related suspension and brake components for wear before installing the new hub assembly.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. Premium seals, precision bearing geometry, and 100% tested ABS sensors are used to support consistent performance in the listed Ram 1500 and Ram 1500 Classic front applications.
