1. Rust Inspection Area
Fig. 10, Hendrickson RS Series Rust Inspection
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 han-
gar (double-lock-bolt design) lock bolt nuts. If a
loose connection has caused pin hole wear, re-
place the hangar.
3. Inspect the pin hole in the outboard leg of the
number one spring hangar (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
and loss of vehicle control. This could result in
serious personal injury or property damage.
4. Inspect the cam surface of the number-two
spring hangar for wear due to operating mileage.
Also, inspect the outside legs for wear which can
be caused by worn spring eye bushings.

NOTE: RTE2 (extended-leaf-spring) suspen-
sions require a minimum gap of 3/8 inch (9.5
mm) between the cam surface of the number-
two spring hangar and the top of the main leaf
in the unloaded condition. See
gap is less than 3/8 inch (9.5 mm), the
extended-leaf portion of the spring will not per-
form satisfactorily for an empty ride.
5. Inspect the cam surface on the number-three
spring hangar (extended-leaf-springs only) for
wear. Excessive wear will reduce the gap avail-
able at the number-two spring hangar. See the
previous note.

6. Place a block of wood on the leaf spring. See
Fig. 12. Place a pry bar on the block of wood
and insert the end of the pry bar under the frame
hangar. Attempt to lift the frame hangar, as
shown in
and the brakes applied, attempt to rock the chas-
sis back and forth while observing the spring
eye. In either case, if 1/8 inch or more of move-
ment is observed, the bushing and pin should be
replaced. This also could indicate that a broken
spring eye and spring are connected to the
spring hangar through the wrapper eye of the
second leaf. In this case, the main leaf or the
complete spring should be replaced immediately.
