(3) Install yoke on front output shaft (Fig. 97).
Install a new yoke nut onto the front output shaft.
(4) Using Spanner Wrench 6958 (Fig. 98), tighten
the yoke nut to 176-271 N·m (130-200 ft. lbs.) torque.
(5) Install propeller shaft. (Refer to 3 - DIFFER-

POSITION SENSOR
DESCRIPTION
The transfer case position sensor is an electronic
device whose output can be interpreted to indicate
the transfer case's current operating mode. The sen-
sor consists of a five position, resistive multiplexed
circuit which returns a specific resistance value to
the Powertrain Control Module (PCM) for each trans-
fer case operating mode. The sensor is located on the
top of the transfer case, just left of the transfer case
centerline and rides against the sector plate rooster-
comb. The PCM supplies 5VDC (+/- 0.5V) to the sen-
sor and monitors the return voltage to determine the
sector plate, and therefore the transfer case, position.
OPERATION
During normal vehicle operation, the Powertrain
Control Module (PCM) monitors the transfer case
position sensor return voltage to determine the oper-
ating mode of the transfer case. Refer to the Operat-
ing Mode Versus Resistance table for the correct
resistance for each position (Fig. 99).
