Leak Area	Area	Applicable Engine
(1) Transfer case mating part / lower part (2) Transmission mating part (3) Propeller shaft mounting part (4) Breather part		R 2.0/2.2 Theta 2.0/2.4 Nu 2.0
		Lambda 3.3/3.5/3.8 S 3.0

Symptom	Possible Cause	Countermeasure
Oil leak	Oil leak at transfer case mating part (1)	Adjust or replace, adjust
	Oil leak at lower part of transfer case (1)	Adjust or replace, adjust
	Oil leak trace at transmission mating part (2)	Adjustment
	Oil leak at propeller shaft mounting part (3)	Adjust or replace, adjust
	Oil leak trace around breather (4)	Adjustment
	Turned-over oil seal main lip (2, 3)	Replacement
	Oil seal displaced to one side (2, 3)	Replacement
	Oil seal dislodged (2, 3)	Replacement
	Spline wear (check for spline wear on the transmission)	Adjust or replace, adjust
Noise	"Repeated clicking" noise while driving	Adjustment
	"Repeated knocking" noise from under the vehicle when turning fully	Adjustment
	"Clunk" - noise occurring when the vehicle accelerates or decelerates suddenly. - Spline wear (check the transmission for spline wear)	Adjust or replace, adjust

※ Range of "adjustment" - Clean oil or grease leakage traces. - Check the engine or transmission for oil leaks and whether oil flows downward. - Check the parts related to the problem area.
