Lubing:
Operators, use GAA on the idler arm, tie rod ends, pitman arm, radius rod and upper
ball joint as spelled out in the lubrication instructions in Appendix G of TM 9-2320-
280-10 and TM 9-2320-387-10.
Tire Studs and Nuts
Loose stud nuts can also lead to serious shaking
problems. So make sure studs and nuts are proper-
ly cleaned, inspected and tightened. Here’s how:
•
Use a wire brush to break loose dirt from studs.
Clean the studs with soap and water and allow them
to dry completely.
•
Look for studs that are cracked, broken, rusted,
pitted, bent, or loose. Pay special attention to the
threads for damage. Replace damaged studs.
•
Stud nuts have to be tightened gradually and in
the proper sequence to avoid bent and broken studs.
You’ll find the right tightening order on Page 8-7 of
the -280-20-2 and -387-24-1 TMs.
Tighten all the nuts by hand first, then torque the
nuts to 90-110 lb-ft following the proper pattern.

Wheel weights for balancing
are listed in Fig 167 of TM 9-
2320-280-24P-1. Here they are
along with a few extra weights…
Wheel Balancing
Generally, the steering wheel will shake
when the front wheels aren’t properly bal-
anced. If the shaking gets serious enough, the
wheel studs can loosen or break off, leaving
you with no control over the vehicle as you
move down the road.
To put an end to shaky driving, your
mechanic needs to start with the bubble
wheel balancer, NSN 4910-01-093-0167,
from the No. 1 or No. 2 Common shop sets.
Tire balancing procedures are found on Pages
8-30 and 8-31 of the -280-20-2 TM and
Pages 8-22 and 8-23 of the -387-24-1 TM.
