NOISE AT FRONT SUSPENSION -ALL MODELS
Please record this article on the Service
Bulletin Reference  at the end of the
Steering' and Front Suspension section of your
1956' Passenger Car Shop Nanual. This super-
cedes the article in Service Bulletin No. 312
under the title of Control Arm Bushing Retainers
 - All Models.
The plain washers formerly installed on the
control arm inner shaft bushing retainer cap-
screws are no longer used in production. They
are shown as item 3, Fig. 8, on page 4 and item
5, Fig. 12, on page 6 of the Front Suspension
and Steering section of the 1956 Passenger Car
Shop Manual. Therefore, it is necessary and
important that the bushing retainer capscrews
be torqued to the proper specification.
Noise at the front suspension may result
from bushing looseness at the upper control arm
inner shaft. This can be caused by: the re-
taining screw having backed out leaving the
bushing loose, the bushing retainer being worn
and not holding the inner sleeve of the bushing,
or the bushing itself being worn.
Remove and inspect the bushing retainer.
The inner side of the retainer should have 6
serrations in good condition. The outside of
the retainer should not have, pronounced, galled
spots from the lock washer. Replace the re-
tainer if necessary. Then, be sure to tighten
the capscrews to the specified torque.
If the retaining screw has worked loose,
install a "Nylok" self-locking screw which has
been released under Part No. 1541700. Also a
plain washer, Part No. G446211, has been re-
leased for service to replace the original lock
washer used in production. It is recommended
that this screw and washer be installed in all
cases where the original production retaining
screw ias loosened and a noise condition exists.
The new screw should be tightened to the proper
torque of 35 ft. lbs.
Under no circumstances should there be any
lubricant applied to the bushing or retainer to
cure a noise condition at this point.
