General Characteristics of Gen 3 Wheel Hub Units:

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

  • 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 rows, on the outboard flange, or on the inboard flange
  • Some sensors are serviceable, with a replacement sensor cord
  • Some some are permanently sealed and are non-serviceable


When Installing Gen 3:

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

  • As precision-engineered components, Gen 3 wheel hub units are susceptible to damage from air guns
  • Do not use an impact wrench when installing Gen 3 units
  • Use a torque wrench to apply the specified torque value
  • Only use the axle torque specifications and manufacturer’s recommended installation procedures
  • Do not use a torque wrench as your primary tool to loosen or tighten fasteners


General Applications for Gen 3 Wheel Hub Units:

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

  • Light trucks and sport utility vehicles
