It is not necessary to regularly check rear 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.

To get an accurate reading, the vehicle should be on a level surface.

1. Rear Axle

2. Filler Plug

The proper level for the rear axle fluid is 0 to 3/8 inch (0 mm to 10 mm) below the bottom of the filler plug hole, located on the rear axle.

See Recommended Fluids and Lubricants to determine which kind of lubricant to use.
