When the differential side gear and pinion mate gea r have
been replaced, select the thrust washer (L.H.) by the following
procedure.
(1) Wash the differential side gear and pinion mate gear
with unleaded gasoline and degrease.
(2) Assemble the thrust washers so far used, withou t
confusing the R.H. part with the L.H. part and toge ther
with each gear, VCU, pinion mate washer and pinion
shaft, to the differential cases (A) and (B), and l oosely
tighten the screws.
