When to Check and Change Lubricant

It is not necessary to regularly check the 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


Object Number: 1263576  Size: B3

  1. Drain Plug

  2. Filler Plug

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.

What to Use

Refer to the Maintenance Schedule to determine what kind of lubricant to use. See Recommended Fluids and Lubricants .
