2. Inspect the rubber bushing ends. Replace the
radius rod if there are gaps between the rubber
bushing and the pin or the outer steel sleeve, if
either bushing end contacts a radius rod pin
mounting bolt, if there are cracks in the bushing,
or if part of the rubber bushing extends beyond
the outside circumference of the outer bushing
sleeve.

Freightliner AirLiner
1. Without disconnecting the control rods, attempt
to move (by hand) each of the control rod ends
up, down, in, and out. If there is any movement,
examine the control rods for wear or damage.
Replace if necessary.
2. Inspect the rubber bushings for cracks or cuts.
3. Check for any shifting of the bar pin.
4. Check for cracks in the metal components and
welds.
IMPORTANT: Be sure to follow the maintenance
schedule for checking the torque of the control
rod fasteners; see
Table 1
for control rod torque
values.
32–12 Fastener Torque
Checking, Hendrickson
Tighten the suspension fasteners to the torque val-
ues given in
Table 2 .
All Hendrickson beam end fasteners must maintain
their torque values to firmly clamp the rubber bushing
inner metal tubes to the beam hanger legs.
WARNING
Insufficient beam end fastener torque could cause
the beam to separate from the axle. This will
cause loss of vehicle control resulting in property
damage, serious personal injury or death.
Tighten the nut to the torque value in Table 2 . Do not
over-torque. See Fig. 3 .
