CAUTION:
When installing the steering column, finger-tighten all of the lower bracket and joint bolts; then tighten
them to specification. Do not apply undue stress to the steering column.
NOTE:
●
With the wheels in the straight ahead position, align the slit of
the lower joint with the projection on the dust cover. Insert the
joint until surface "A" contacts surface "B".
●
After installation, inspect the steering column for proper opera-
tion. Refer to
PS-12, "INSPECTION AFTER INSTALLATION"
.
INSPECTION AFTER INSTALLATION

INSPECTION AFTER DISASSEMBLY
Boot
Check boot for tears, cracks and deformation. Replace if necessary.
Gear Housing Assembly
Check gear housing assembly for dents, cracks or damage. Replace as an assembly if necessary.
Outer Socket and Inner Socket
SWING TORQUE
●
Measure the swing torque, using Tool. When ball stud and inner
socket start moving the measured value must be within the
specification. If the reading is outside the specification, replace
the socket.
ROTATING TORQUE
●
Measure the rotating torque, using Tool. If the value is outside
the specification, replace the outer sockets.
AXIAL END PLAY
●
Apply a load of 490 N (50 kg-f, 110 lb-f) to the ball stud axially.
Use a dial gauge to measure the amount of the movement that
the stud makes. If the value is outside the specification, replace
the sockets.
ASSEMBLY
1.
Install the inner sockets.
