How to Check  Lubricant 
To get  an accurate  reading, the vehicle  should be on a 
level  surface. 
If  the  level is  below the bottom 
of the filler  plug  hole, 
you may need to  add  some  lubricant. 
When  the  differential  is cold,  add enough lubricant  to 
raise the  level  to 
0 to 3/8 inch (9.5 mm) below the  filler 
plug hole. 
When  the  differential  is at  operating  temperature 
(warm),  add enough  lubricant  to  raise the  level  to the 
bottom 
of the  filler  plug  hole. 
What  to Use 
Refer  to  the  Maintenance  Schedule  to determine what 
kind  of lubricant  to  use.  See 
Pat? D: Recommended 
Fluids  and Lubricants  on  page
