Rear Axle
When to Check Lubricant
It is not necessary to regularly check rear axle ¯uid
unless you suspect there is a leak or you hear an
unusual noise. A ¯uid 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 ®ller plug hole,
you will need to add some lubricant. Add enough
lubricant to raise the level to the bottom of the ®ller
plug hole.
What to Use
To add lubricant when the level is low, use
SAE 75W±90 Synthetic Gear Lubricant
(GM Part No. 12378261) or equivalent meeting
GM Speci®cation 9986115. To completely re®ll after
draining, add 4 ounces (118 ml) of Limited-Slip
Differential Lubricant Additive (GM Part No. 1052358) or
equivalent. Then ®ll to the bottom of the ®ller plug
hole with the Synthetic Gear Lubricant.
