the lubricant.
1. Fill 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
