(2) Measure the distance“”from the transmission
case mating surface to the reduction drive gear end
surface with ST1 and ST2. (On FWD models, measure
distance from end of case to end of bearing.)
Unit: mm

ST1 398643600 GAUGE
ST2 499577000 GAUGE
(3) Calculation equation:
Unit: mm
T = (L + 0.4)
T : Clearance between end of reduction drive gear
and end of rear drive shaft. (Clearance between
end of reduction drive gear and end of bearing on
FWD model)
L : Distance from end of extension case to end of
rear drive shaft. (Distance from end of case to
point at bearing location)
0.4: Gasket thickness
: Height from end of transmission case to end of
reduction drive gear. (Height from end of case to
end of bearing on FWD models)
Select suitable thrust needle bearing from among those
listed in the following table to adjust clearance in the
