on the frame or some other part of the chassis.

Spring Single and Tandem
Radius Rod Bushing Check
1. Without detaching the torque arms, use your
hand to attempt to move each of the radius rod
ends up, down, in, and out. If there is any move-
ment, replace the torque arm.
2. 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.
3. Inspect the rubber bushing ends. See Fig. 1 . Re-
place the torque arm for any of the following rea-
sons:
•
There are gaps between the rubber bush-
ing and the pin or the outer steel sleeve.
•
Either bushing end contacts a torque arm
pin mounting bolt.
•
There are cracks in the bushing.
•
Part of the rubber bushing extends beyond
the outside diameter of the outer bushing
sleeve.
Freightliner Spring Tandem
Suspension Equalizer Bushing
Check
1. Block the frame up enough to take the weight of
the chassis off of the springs. Attempt to move
the equalizer up and down, by using a pry bar
between the top of the equalizer and the top of
the equalizer bracket. Apply hand-pressure only.
See
Fig. 2 . If movement at the center of the
equalizer exceeds 1/8 inch (3 mm), replace the
equalizer bushings.
2. With the vehicle unloaded, attempt to move the
equalizer side to side using a pry bar between
the equalizer and frame rail. Apply hand-pressure
only. See
Fig. 3 . If clearance between the equal-
izer assembly and any frame component or fas-
tener is less than 1/8 inch (3 mm), replace the
equalizer bushings.
52-Inch Multi-leaf Spring
Component Check
No lubrication is required on the 52-inch multi-leaf
spring rear suspension.
Inspect the stabilizer bar, if present, for irregular
bushing wear or cracks in the brackets. Check the
rubber helper spring, if present, for cracks.
