When to Check and Change Lubricant
It is not necessary to regularly check front axle fluid unless you suspect there is a leak or you hear an unusual noise. A fluid loss could indicate a problem. Have it inspected and repaired.
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, located on the front axle, you may need to add some lubricant:
| • | When the differential is cold, add enough lubricant to raise the level from 1/2 inch (12 mm) to about 5/8 inch (18 mm) below the filler plug hole for the 1500 series, and from 1/4 inch (6 mm) to about 3/8 inch (10 mm) below the filler plug hole for 2500 series. |
| • | 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 Recommended Fluids and Lubricants .
