- To install, reverse the removal procedures.
WARNING
- Smear the splines (A) with molybdenum type high pressure grease.
- When install the coupling, be careful not to damage the oil
seal (B).
- After replacing the coupling, reset the 4WD ECU's clutch learing using
the diagnostic tool.
(Refer to 4WD Control System - "Repair procedures")
Description
The 4WD ECM controls the Pump Motor Pump (Actuator) to generating an oil pressure. The pressure engages a multiple disk clutch to transfer torque to the rear wheels. The torque to the rear wheels varies according to the pressure on the clutch.
