MAINTENANCE, LUBRICATION AND SERVICE
CHASSIS MAINTENANCE
Springs
The spring package is fastened to the
axle beam with U-bolts. It is important
that the U-bolt nuts are properly
tightened. The nuts may loosen up with
time. Severe service will loosen them
faster. Loose U-bolts can cause springs
to break, axle misalignment, hard
steering and abnormal tire wear. Inspect
the chassis for broken springs, shocks,
loose or broken axle U-bolts. If any of
these are found, contact your local
Mack dealer.
Spring Bushings
When lubricating the springs, lift the axle
off of the floor, 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. If the spring bushings
are greased without taking the load off,
high wear and lower lifetime will occur
because grease is not able to reach the
contact surfaces. If the vehicle is for
severe service applications, increase the
frequency of spring bushing lubrication.
Rubber Bushings
Rubber bushings are used for extended
service life. If your vehicle is equipped
with rubber bushings DO NOT lubricate
them. Replace the leaf spring if it is
damaged or has premature or excessive
wear.
