        2. 09953-05010
      NOTE:

      Do not overtighten SST, as doing so will damage the front differential side gears, conical springs, front No. 1 differential side gear thrust washers and front differential case.

      HINT: 

      • Tighten SST until there is clearance between the front differential pinions and front differential side gears.
      • When removing the front differential pinions, do not overtighten SST, as it is necessary to rotate the front differential side gears.
    2. Install SST as shown in the illustration, rotate the front differential side gear, and then remove the 2 front differential pinions and 2 front differential pinion thrust washers from the front differential case.
