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 - 0.59) - (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

 Most common causes of corrosion

The most common causes of corrosion are: 1. The accumulation of moisture retaining dirt and debris in body panel sections, cavities, and other areas. 2. Damage to paint and other protective coatings caused by gravel and stone chips or minor accidents. Corrosion is accelerated on the vehicle w

 START

CAUTION Do not turn the ignition switch to the “START” position while the engine is running. The engine is started in this position. The starter cranks the engine to start it. When the key is released (after the engine has started), the key automatically returns to the “ON” position.
