ACDelco Professional Wheel Hub and Bearing Assembly

The ACDelco Professional Wheel Hub and Bearing Assembly is a complete, pre-assembled wheel hub and bearing unit (also called a hub bearing assembly or wheel bearing and hub assembly). It supports the vehicle's weight and lets the wheel spin smoothly and with low friction. ACDelco Professional parts are designed to meet or exceed the fit, form, and function of the original equipment part.

Key Features:

• Pre-assembled hub and bearing unit, which simplifies installation compared with pressing in a separate bearing
• Sealed bearing design helps keep out moisture, dirt, and road contaminants, and holds in lubricant
• Precision-manufactured components help the unit run smoothly and quietly
• Built for durability under everyday driving loads, braking forces, and cornering
• Engineered for an OE-style fit, with mounting flanges and studs matched to the application
• Backed by ACDelco, GM's parts brand, which has a long history in OE and aftermarket replacement parts

A worn wheel hub bearing can cause humming or growling noise, vibration, or looseness at the wheel. Replacing the assembly helps restore smooth rolling, steering stability, and braking performance. Each part number in this product line is a specific application, so choose the one that matches your needs.
