J 24429:  Side Bearing Backlash Spanner

NOTE:
  • The differential side bearing preload is adjusted by the 2 adjusting nuts in the bearing bore. The bore and the bearing cap provide the mating threads for the bearing nut.
  • The differential must be initially preloaded in order to determine the backlash of the gear set. After the backlash is set, the final bearing preload is set.
  • The rotating torque of the drive pinion must be within specifications before the pinion gear bearing retainer can be installed.
