NOTES: (1) When checking tightness of major fasteners on new trucks,
the values may be less than the recommended specifica-
tion due to metal deformation and fastener stretch. This is
a normal occurrence and does not indicate that the fasten-
ers were not correctly tightened during assembly. Tighten
to recommended specifications.
(2) Steer Wheel Spindle Nut Bearing Adjustment (For steer
axles with castellated nut and cotter pin).
Tighten spindle nut (bearing adjustment nut) until bearings
bind slightly when rotated, then back off to nearest slot
in nut and lock with cotter pin.
