8. Raise vehicle, then remove mounting bolt (lower side) of lower
joint shaft and remove lower joint shaft and upper shaft as an
assembly.
INSPECTION AFTER REMOVAL
Check for damage to steering column jacket tube. If damage is found, replace steering column with new
one.
If vehicle has been in a collision, check column length “L1” and
“L2” as shown. If out of specification, replace steering column
with new one.
Check for proper lubrication, apply grease as necessary.
INSTALLATION
Installation is in the reverse order of removal.

CAUTION:
When installing the steering column, finger-tighten all of the lower bracket and joint retaining
bolts; then tighten them to specification. Do not apply undue stress to the steering column.
The lower nut on the upper joint may not be reused.
NOTE:
Align slit of the coupling joint with projection on dust cover. Insert the
joint until surface "A" contacts surface "B".
After installation, turn steering wheel to make sure it moves
smoothly. Make sure the number of turns are the same from the
straight-forward position to left and right locks. Make sure that
the steering wheel is in a neutral position when driving straight
ahead.
When installing steering column to steering member, install
mounting nut from front side of vehicle.
INSPECTION AFTER INSTALLATION
After installing steering column to vehicle, check tilt device and its operation range is as specified.
Check if steering wheel operation can turn to the end of the left
and right stops smoothly.

ASSEMBLY
Assembly is in the reverse order of disassembly.
Install new tamper resistant self-shear screws.
INSPECTION AFTER ASSEMBLY
When the steering wheel does not turn smoothly, check the steering column as follows:
1. Check the column bearings for damage or unevenness. Lubricate with recommended multi-purpose
grease. Replace the steering column as an assembly, if necessary.
2. Check the column tube for deformation or breakage. Replace the steering column as an assembly, if nec-
essary.
3. If the vehicle has been involved in a collision, or if noise and rat-
tles are heard during a turn, check the length "L" of the column.
If out of specification, replace the steering column as an assem-
bly.
4. Check for proper lubrication, apply grease as necessary.
5. Check for wear around the seal edges, replace the steering col-
umn as an assembly as necessary.
6. Check for corrosion or pitting around the seal sliding area.
7. After installing the steering column, check the tilt mechanism for
proper operation.
CAUTION:
Replace the column if it is depleted of grease, worn, dam-
aged, or if any scratches or coating separation is present
on the shaft seal area.
During lower joint detachment, insert a tool into the yoke
groove to prevent gouging damage.
