7. Align the matching mark of differential case with the mark of drive gear, then place drive gear.
8. Apply thread locking sealant into the thread hole of drive gear. Use Genuine High Strength Thread Locking Sealant or
equivalent. Refer to GI-44
.
CAUTION:
Drive gear back and threaded holes shall be cleaned and
degreased sufficiently.
9. Install drive gear on the mounting bolts, and then tighten to the specified torque. Refer to "COMPONENTS".
CAUTION:
 Tighten bolts in a crisscross fashion.
 After tightening the bolts to the specified torque, tighten
the bolts additionally by turning the bolts 31 to 36
degrees.
10. Press side bearing inner races to differential case, using the drift and the base.
CAUTION:

INSPECTION AFTER REMOVAL
Visual Inspection
 Check suspension arm and bushing for deformation, cracks, or damage. If any non-standard condition is
found, replace it.
 Check boot of ball joint for cracks, or damage, and also for grease leakage.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measuring, move ball joint at least ten times by hand to check for smooth movement.
 Hook a spring balance at cotter pin mounting hole. Confirm spring balance measurement value is withi n the specifications when ball
stud begins moving.
 If it is outside the specified r ange, replace suspension arm assem-
bly.
Rotating Torque Inspection
 Attach mounting nut to ball stud. Make sure rotating torque is within the specifications with a preload gauge (SST).
 If it is outside the specified r ange, replace suspension arm assem-
bly.
Axial End Play Inspection
 Move tip of ball joint in axial direction to check for looseness. Swing torque:
