Detailed Description

Timken HA590352 is engineered using OE-developed testing methods that guide the design, materials, and manufacturing process of the hub bearing assembly. The result is a front hub assembly with controlled runout, improved braking feel, and reduced vibration at the wheel end. Precision internal geometry and refined bearing surfaces help support load capacity, while the integrated ABS sensor is tested to monitor wheel speed for anti-lock braking systems. This part number is a strong match for drivers searching for a front wheel bearing and hub assembly for 2003-2018 Chevrolet Express 2500 and Express 3500, as well as 2006-2018 GMC Savana 2500 and Savana 3500 applications.

What It Helps Solve

• Wheel bearing noise from a worn front hub assembly
• Steering wheel shake or vibration caused by hub runout
• ABS warning light concerns related to wheel speed signal issues
• Uneven braking feel linked to hub endplay or bearing wear
• Front wheel looseness on compatible Chevrolet and GMC van and truck applications

Installation Notes and Tips

Verify flange bolt hole count, wheel pilot diameter, brake pilot diameter, hub pilot diameter, and bolt circle diameter before installation. This assembly is for non-driven front positions only. Confirm vehicle year, model, and GVWR notes for Chevrolet Express 3500 and GMC Savana 3500 applications, since fitment varies by configuration. For best results, inspect the mating surfaces, ABS connector routing, and surrounding brake components during replacement.

Quality Assurance

Timken manufactures this hub assembly with OE-based validation, premium seal construction, precision bearing profiles, and tested ABS sensor performance to support consistent operation and long service life.
