Lubrication Notes
1
Spring Hanger
Use a lithium based grease with
specication API NLGI No. 2. When
lubricating the left and right sides of
the front springs, lift the axle off of
the oor, suspend the frame with
axle stands and lower the axle.The
spring bushings are now in the
position where grease can be added
to the contact surfaces.
NOTE
The rock guard will have to be removed (if
equipped).
NOTE
Always grease a Mack front axle with the
wheels on the ground.
NOTE
To grease non-Mack axles, they are
typically greased with the wheels on the
ground. Consult with the axle
manufacturer for the latest
recommendation.
