Measure the length L as shown in the figure if vehicle has been
involved in a minor collision. Replace steering column assembly
if outside the standard.

Measure steering column assembly rotating torque using pre-
load gauge [SST: ST3127S000]. Replace steering column
assembly if outside the standard.

INSTALLATION

Installation is the reverse order of removal. For tightening torque, refer to PS-12, "COMPONENTS" .

Install steering column assembly with tilt neutral condition to steering column assembly. Start installation
from vehicle front at this time.

When installing lower shaft to steering gear assembly, follow the procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn pinion assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower shaft (C) aligning with the projection (A)
of rear cover cap (1). Make sure that the slit part of lower shaft
(C) is aligned with both the projection (A) of rear cover cap (1)
and the marking position (B) of gear housing assembly.
INSPECTION AFTER INSTALLATION
Make sure that steering wheel operates smoothly by turning several times from full left stop to full right stop.
