Bearing M/C Hub 1979-81 Outer

The Bearing M/C Hub 1979-81 Outer from Allstar Performance is an OEM-specification replacement wheel bearing designed for first-generation metric hub assemblies on GM vehicles spanning 1979 to 1981. This outer bearing is a critical suspension component that handles radial and axial loads while allowing smooth wheel rotation under all driving conditions. Whether you're rebuilding a classic Chevrolet, Pontiac, or Oldsmobile hub assembly or performing preventive maintenance on a vintage GM platform, this bearing delivers the precision fit and durability required for safe, quiet wheel operation.

Manufactured from hardened steel and engineered to match the metric hub design of early 1980s GM production vehicles, this outer bearing is precision-ground to tight tolerances that ensure proper seating within the hub assembly. The steel construction provides excellent load-bearing capacity and corrosion resistance, essential for long-term reliability in both dry and wet environments. Installation requires proper bearing preload adjustment and greasing according to factory specifications—a step that cannot be overlooked if you want to avoid premature wear, bearing noise, or catastrophic hub failure during highway driving.

Mechanics and restoration enthusiasts who are servicing or rebuilding metric hub assemblies will find this bearing essential for complete suspension restoration. The outer bearing works in tandem with its inner counterpart to distribute wheel loads and allow free rotation of the hub and rotor assembly. Proper installation—including cleaning the hub bore, applying fresh bearing grease, and setting correct preload—ensures smooth operation and maximum service life. This bearing is sold individually, so verify your hub assembly contains two bearings per wheel before ordering.
