GEN 1 WHEEL HUB


High quality wheel end replacement parts for domestic and import applications.

Gen 1 wheel bearings can be found in driven front and rear wheels. They may also be in integral drum designs on the non-driven wheels of smaller cars. (Always refer to and follow vehicle and product specifications.)

Characteristics

  • 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
  • Generally greased and sealed for life
  • 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

GEN 2 WHEEL HUB


High quality wheel end replacement parts for domestic and import applications.

Gen 2 wheel bearings can be found in non-driven front or rear wheels. (Always refer to and follow vehicle and product specifications.)

Characteristics

  • Consist of a double row ball or tapered design
  • Features an outer ring with an integral flange which replaces the function of a separate hub
  • Flanged outer ring is designed to function as a lightweight structural component
  • Flange includes threaded holes (also called studs) and spigot (also called a pilot) to center and mount the brake and wheel
  • Can be found in non-driven front or rear wheels
  • May also include an impulse wheel (also called a tone ring) as part of the Anti-Lock Braking System, Traction Control System and/or Stability Control System
  • Typically, the impulse wheel is located on the outer ring
  • The impulse wheel is not serviceable

GEN 3 WHEEL HUB


High quality wheel end replacement parts for domestic and import applications.

Gen 3 wheel bearings can be found in light trucks and sport utility vehicles. (Always refer to and follow vehicle and product specifications.)

Characteristics

  • Can either be a tapered or ball design
  • Consist of a double row bearing design that incorporates a flange for wheel and brake rotor attachment and a second flange for fixing the unit to the suspension
  • Outer ring flange is bolted to the suspension
  • The rotating inner ring, with its tough flange, spigot (also called, pilot) and threaded holes (also called, studs), is designed for mounting of the brake and wheel
  • Greased and sealed
  • Used for both driven and non-driven wheel applications
  • For driven wheel applications, torque is transmitted to the inner ring via a spline, which is included
  • Some Gen 3 hub wheel bearings may also include a wheel speed sensor as part of the Anti-Lock Braking System, Traction Control System, and/or Stability Control System
  • The sensor can be located between the bearing row on the outboard or inboard flange
  • Some sensors are serviceable with a replacement sensor cord
  • Some are permanently sealed and are non-serviceable
