General Characteristics of Gen 1 Wheel Hub Units:

(ALWAYS refer to, and follow vehicle and product specifications)

  • Cartridge style wheel bearings
  • May either be a ball or tapered design
  • Are double row angular contact bearings
  • Most have a split inner ring
  • Presence of split inner ring indicates that when hand rotated, each half of the bearing has the ability to rotate independently of the other

  • Certain Gen 1 wheel bearings may include a wheel speed sensor magnetic impulse ring
  • The impulse ring is built into the seal on one side of the bearing
  • Gen 1 wheel bearings with an impulse ring can only be installed in one direction
  • The encoder ring must be placed next to the wheel speed sensor in order for Anti-Lock Braking System, Traction Control System, and Stability Control System to function

(ALWAYS refer to and follow vehicle and product specifications)

  • As precision-engineered components, Gen 1 wheel hub units are susceptible to damage from air guns
  • Do not use an impact wrench when installing Gen 1 units
