Nilight Front Wheel Bearing Hub for Chevrolet Trailblazer 2002–2009 — Pre-Greased, Built-In Speed Sensor, 6-Lug

The Nilight front wheel bearing hub assembly is a direct-fit replacement hub for Chevrolet Trailblazer and related GM models from 2002–2009, delivering pre-greased bearings, a built-in speed sensor, and a 6-lug flange for reliable road performance.

When a front hub begins to show noise, play, or an ABS light triggered by a faulty speed sensor, replacing the entire assembly ensures correct alignment, sealing, and sensor operation in one step. This Nilight unit (part reference 513188/WE60887 and cross-references) is manufactured from alloy steel and supplied pre-greased, engineered to meet OE-style tolerances for a straightforward swap on compatible GM SUVs and trucks.

How does this hub improve driving stability and safety?

Replacing a worn or noisy hub assembly restores precise wheel positioning and reduces play that can cause vibration or uneven tire wear. A functioning speed sensor also ensures accurate wheel-speed data to your vehicle’s stability and braking systems.

• Reduces wheel wobble and vibration at speed
• Helps maintain correct wheel alignment and tire wear patterns
• Restores reliable ABS/traction sensor signals for safety systems
• Durable alloy-steel construction for long-term performance

What should you know before installation?

Installation is similar to other hub assemblies but may require common shop tools and torque specifications specific to your model year. Verify cross-reference numbers and confirm whether the drive axle or brake components need to be removed to access the hub.

• Confirm part numbers: 513188, WE60887, 713188, BR930397, BR930470, 12413037
• Designed for front left or right positions on 6-lug vehicles
• Pre-greased bearings reduce initial preparation, but torque and seal checks remain necessary
