32. Install output shaft in transmission case. CAUTION:
Do not mistake front of shaft for rear because both sides
look similar (thinner end is front side).
33. Install bearing race to output shaft.
34. Install rear extension assembly (2WD models) or adapter case assembly (4WD models) according to the following procedures.
a. 2WD models
i. Apply recommended sealant (Genuine Anaerobic Liquid Gasket or equivalent. Refer to GI-15, "
Recommended Chemical Prod-
ucts and Sealants".) to rear extension assembly as shown.
CAUTION:
Completely remove all moistu re, oil, old sealant and any
foreign material from the transmission case and rear exten-
sion assembly mating surfaces.
ii. Install rear extension assembly to transmission case. CAUTION:
Insert the tip of parking rod between the parking pawl and
the parking actuator support when assembling the rear
extension assembly.
