1. A method of measuring bearing preload in a differential gear assembly'"'"'s angular contact ball bearing set, the bearing set supporting a pinion shaft within a housing having at least one cylindrical opening formed in an exterior surface of the housing, said method comprising the steps of:

  • providing a multi-axis load cell having a spherical load button;

    positioning said spherical load button within one of said cylindrical openings;

    rotating said pinion shaft relative to said housing so that said rotating pinion shaft imparts a torque to said housing through said bearing set, wherein said housing rotates and an inner surface of said cylindrical opening abuts said load button; and

    measuring a force applied by said housing against said load button.
