   Turn

   *b

   Hold

   NOTE:

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

   HINT: 

   • Tighten SST to create the necessary clearance to install the front differential pinions.
   • When installing the front differential pinions, do not overtighten SST, as it is necessary to rotate the differential side gears.
4. Coat the 2 front differential pinions and 2 front differential pinion thrust washers with Toyota Genuine ATF WS.
