Fluid - Transfer Case: Testing and Inspection

Transfer Oil (4WD A/T) and Rear Differential Oil (4WD) Inspection

1. Check transfer case or differential for evidence of oil leakage. Repair leaky point if any.
2. Make sure that vehicle is placed level for oil level check.




3. Remove level plug of transfer or differential and check oil level. Oil level can be checked roughly by means of level plug hole.

That is, if oil flows out of level plug hole or if oil level is found up to hole when level plug is removed, oil is properly filled. If oil is found insufficient, pour specified amount of specified oil referring to Transfer Oil Change or Rear Differential Oil Change.

4. Tighten level plug to specified torque referring to Transfer Oil Change or Rear Differential Oil Change.
