GENERAL INFORMATION





  • The wheel bearing is a unit ball bearing (double-row angular contact ball bearing) which incorporates the oil seals and is highly resistant to thrust loads.
  • The driveshaft incorporates lightweight and compact EBJ-ETJ type constant velocity joints.
  • The rear driveshaft spline diameter on the wheel-side has been increased, improving torsional strength.
  • The protector cover of magnetic encoder is equipped to driveshaft.
  • The mechanical type limited slip differential has been equipped.
  • Lead-free grease for the constant velocity joint is adopted.
  • Hexavalent chromium is eliminated from the dust cover material.
  • The number of parts is reduced by integrating the magnetic encoder for ABS wheel speed detection into the wheel bearing.
note
    EBJ (High Efficiency Compact Birfield Joint): the lighter and smaller constant velocity joint compared with the conventional BJ has been achieved by adopting the eight small balls.
    ETJ (High Efficiency Compact Tripod Joint): the lighter and smaller constant velocity joint compared with the conventional TJ has been installed.
