Transfer Case
When to Check Lubricant
Refer to Maintenance Schedule 0 330 to
determine when to check the lubricant.
1. Fill Plug
2. Drain Plug
To get an accurate reading, the vehicle
should be on a level surface.
If the level is below the bottom of the fill
plug (1) hole, located on the transfer case,
some lubricant will need to be added. Add
enough lubricant to raise the level to the
bottom of the fill plug (1) hole. Use care not
to overtighten the plug.
Do not overfill the transfer case as this may
cause seepage around bearing caps.
When to Change Lubricant
See Maintenance Schedule 0 330 to
determine how often to change the
lubricant.
What to Use
See Recommended Fluids and Lubricants
0 363 to determine what kind of lubricant
to use.

When to Check and Change Lubricant
It is not necessary to regularly check front
axle fluid unless a leak is suspected, or an
unusual noise is heard. A fluid loss could
indicate a problem. Have it inspected and
repaired.
