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.
For all vehicles, excluding vehicles equipped with the
6.0L V8 Engine, the proper level is from 0 to 0.40 inch
(0 to 10 mm) below the bottom of the filler plug hole,
located on the rear axle.
For vehicles equipped with the 6.0L V8 Engine, the
proper level is from 0.6 inch to 1.6 inches (15 mm to
40 mm) below the bottom of the filler plug hole, located
on the rear axle differential cover.
Add only enough fluid to reach the proper level.
What to Use
To determine what kind of lubricant to use, see
Recommended Fluids and Lubricants on page 6-12.
For vehicles equipped with the SS package, to add
lubricant when the level is low, use SAE 75W–90
Synthetic Axle Lubricant (GM Part No. U.S. 12378261, in
Canada 10953455) meeting GM Specification 9986115.
To completely refill after draining, add 5.5 ounces
(163 ml) of Limited-Slip Axle Lubricant Additive
(GM Part No. U.S. 1052358, in Canada 992694).
Then fill to the bottom of the filler plug hole with the
Synthetic Gear Lubricant.
