Rear Axle
When to Check Lubricant
It is not necessary to regularly check rear 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.
The proper level for the 1500 Series is from 5/8 inch to
1 5/8 inch (15 mm to 40 mm) below the bottom of
the filler plug hole. The proper level for the 1500 HD
Series, 2500 Series, 2500 HD, and 3500 Series is from
0 to 1/2 inch (0 to 13 mm) below the bottom of the
filler plug hole. The proper level for the 1500 and
2500 Series vehicles with QUADRASTEER™ (4 Wheel
Steer) is from 0 to 1/4 inch (0 to 6 mm) below the
filler plug hole. Add only enough fluid to reach the
proper level.
What to Use
