same manner. The removal and installation instruc-
tions are applicable to both.
Spherical Bearing Wear Limits
It is necessary to determine the condition of spherical
bearings on steering linkage components for opti-
mum steering performance. Ball diameter new
dimensions and maximum allowable wear specifica-
tions are listed in Table 1. Bearings that exceed the
maximum wear limits must be replaced.

If premature wear of the bearings is evident, check
the automatic lubrication system to ensure the proper
amount of lubrication is being received at the joint(s)
in question. If lubrication is done manually, ensure
that a sufficient amount of grease is being applied on
a regular basis. Refer to Section P, Lubrication and
Service, for information on proper lubrication inter-
vals.
