Detailed Description

Timken HA590023 is built for front right wheel-end service on 2004-2008 Chevrolet Colorado, 2004-2008 GMC Canyon, 2007-2008 Isuzu i-370, and 2006 Isuzu i-350 models. The assembly uses precision bearing profiles, uniform internal geometry, and refined surface finishes to support load capacity, bearing life, and efficient operation. Low runout helps reduce vibration and noise while supporting more consistent braking performance. Premium sealing features are used to improve contamination control and seal durability, and the integrated ABS sensor is tested to monitor wheel speed for anti-lock braking systems. This part cross-references QuickSteer 515111 and SKF BR930703 for the same application.

What It Helps Address

• Wheel bearing noise from the front right corner
• Vibration or looseness at the wheel hub
• ABS warning concerns related to wheel-speed signal loss
• Uneven braking feel caused by hub runout
• Wear from contamination entering the wheel-end assembly

Installation Notes and Tips

Confirm the vehicle is front right, driven, and matches the listed fitment before installation. Verify spline count, bolt circle diameter, wheel pilot diameter, and hub pilot diameter against the original part. Inspect the mating surfaces, axle interface, and ABS connector condition during replacement to help ensure proper seating and sensor operation. Fits 2004-2008 Chevrolet Colorado, front right. Fits 2004-2008 GMC Canyon, front right. Fits 2007-2008 Isuzu i-370, front right. Fits 2006 Isuzu i-350, front right.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing methods for hub bearing assemblies, with attention to design, materials, and process consistency. The ABS sensor is individually tested for wheel-speed monitoring, and the sealing system is built to support contamination resistance and longer service life.
