Inspection
NOTE: The tilt steering column type is shown; the con-
ventional steering column is similar except for the tilt
mechantsm.
Check the steering column ball bearing and the steer-ing joint bearings for play and proper movement. lf
there is noise or if there is excessive play, replace the
steering column as an assembly.
Check the retaining collar for damage. lf it is dam-
aged, replace the retaining collar.
Check the absorbing plates, absorbing plate
and sliding capsules for distonion or breakage.

1.Move the tilt lever from the loose position to lockposition 3 to 5 times; then measure the tilt leverpreload l0 mm {0.4 in) from the end ofthe tilt lever.
Preload: 70 - 90 N (7 - 9 kgf. 15 - 20 lbf)
lf the measurement is out of the specification,
adjust the pfeload using the following procedures.
a. Loosen the tilt lever, and set the steering column
in the neutral position.
b. Remove the 6 mm lock bolt and remove the stop.
c. Adjust the preload by turning the tilt lock bolt left
or flgnr.
d. Pull up the tilt lever to the uppermost position and
install the stop. Check the preload again. lf the
measurement is still out of specification, repeat
the above procedures "a" through "c" to adjust.
CAUTION: Be caretul not to loosen tho tilt lever
