Rear Drive Shaft: Adjustment

1. Using the ST, measure the distance "A" from ST end face to rear drive shaft thrust needle bearing catch surface.

2. Using the ST, measure the height "B" from the intermediate case mating surface to the ST end face.
   NOTE: Place the measurement tool at the dent on ST upper side to measure.

4. Obtain the thickness of thrust bearing using the following formula to select the thrust bearing.

T mm = (A - 15) - (B - C) - (0.05 - 0.25)

[T in = (A - 0.591) - (B - C) - (0.002 - 0.01)]

T: Thrust bearing thickness

A: Height from the ST end face to the rear drive shaft thrust needle bearing catch surface

B: Height from the mating surface of the intermediate case to the ST end face

C: Height from the ST end face to the transfer clutch assembly thrust needle bearing catch surface 15 mm (0.591 in): Thickness of ST

0.05 - 0.25 mm (0.002 - 0.01 in): Clearance
