Rear Suspension Check
Freightliner Spring Suspension
WARNING
Do not replace individual leaves of a damaged leaf
spring assembly; replace the complete spring as-
sembly. Visible damage (cracks or breaks) to one
leaf causes hidden damage to other leaves. Re-
placement of only visibly damaged parts is no as-
surance that the spring is safe. Failure to replace
a damaged spring assembly could cause an acci-
dent, resulting in serious personal injury or prop-
erty damage.
Replace worn, cracked, or damaged spring
brackets. Failure to do so could result in bracket
breakage, possibly leading to loss of vehicle con-
trol and resulting in personal injury or property
damage.
1.
Inspect the forward and rear spring brackets and
equalizer brackets for wear, cracks, and other
damage. If any of these conditions exist, replace
the damaged bracket(s). See
Group 32
of the
122SD and Coronado Workshop Manual
for in-
structions.
2.
Inspect the tandem-axle frame crossmember and
gussets for wear, cracks, and other damage. If
any of these conditions exist, replace the dam-
aged parts. See
Group 32
of the
122SD and
Coronado Workshop Manual
for instructions.
NOTICE
Failure to replace the suspension crossmember or
gussets if they are cracked, worn, or otherwise
damaged could result in damage to the vehicle
chassis.
3.
Without detaching the torque arms, attempt to
move (by hand) each radius-rod end up, down,
in, and out. If there is any movement, replace the
torque arm. If a torque arm needs to be re-
placed, see
Group 32
of the
122SD and Coro-
nado Workshop Manual
for instructions.
4.
Inspect the weld seams between the torque arm
tube and the shorter bushing tubes. If there are
cracks, replace the torque arm. Do not weld the
torque arm for any reason.
5.
Inspect the rubber bushing ends. See
. Re-
place the torque arm for any of the following rea-
sons:
•
if there are gaps between the rubber bush-
ing and the pin or outer steel sleeve;
•
if either bushing end contacts a torque arm
pin mounting bolt;
•
if there are cracks in the bushing;
•
if part of the rubber bushing extends be-
yond the outer circumference of the outer
bushing sleeve.
