Detailed Description

This Dorman wheel bearing and hub assembly, part number 951-178, is built for front-wheel service on select Chevrolet and GMC 3/4-ton and 1-ton trucks and Suburban models.

The assembly is intended for vehicles without an anti-lock braking system sensor at the hub and does not include flange bolts, mounting hardware, or wheel studs.
