components, loss of vehicle control, and possible
personal injury or property damage.
2. Inspect each frame hanger for any evidence of
cracks in the vertical mounting flange. See
Fig.
9
.
3. Inspect each frame hanger for evidence of
cracks in the horizontal mounting flange adjacent
to the vertical drive pin area. See
Fig. 10.
4. Inspect each frame hanger for severe rust on the
horizontal mounting flange adjacent to the verti-
cal drive pin area. See
Fig. 11.
5. Inspect the load cushions for cuts and swelling.
Cushions cut by the retaining lips of the saddles
or frame hangers indicate the cushions may not
be the correct hardness or configuration for the
vehicle operation.
6. Inspect the lower side of the vertical drive bush-
ings for evidence of torn or shredded rubber.
Check that the concave washers are installed
with the lips pointing downward.
7. Inspect the saddles and saddle cap fasteners for
wear. The allowable thrust washer wear in alumi-
num saddles is up to 3/16 inch (4.8 mm) into the
saddles as measured at the top of the thrust
washer diameter. Check that the locknuts are
torqued to specification to prevent wear of the
beam center bushings into the legs of the
saddles. See
Group 00 of this manual for torque
specifications.

1. Park the vehicle on a level surface, apply the
parking brakes, and chock the front tires.
Raise the rear of the vehicle until the rear wheels
are suspended in the air, then support the ve-
hicle with safety stands.
2. Check the torque of the number-one spring
hanger (double-lock-bolt design) lock bolt nuts. If
a loose connection has caused pin hole wear,
replace the hanger.
3. Inspect the pin hole in the outboard leg of the
number-one spring hanger (draw-key design) for
wear or elongation.
WARNING
Wear at this point requires hanger replacement, or
premature fracture of the spring hanger pin may
occur, with possible separation of components
