INSTALLATION
Installation is in the reverse order of removal.
• With the steering wheel 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 removing/installing or replacing steering components, check
wheel alignment. Refer to
FSU-6, "Front Wheel Alignment"
.
• After adjusting wheel alignment, adjust neutral position of the
steering angle sensor. Refer to
STEERING ANGLE SENSOR NEUTRAL POSITION : Special
• Bleed the air from the steering hydraulic system. Refer to
"Air Bleeding Hydraulic System"
.
INSPECTION AFTER INSTALLATION
• Check that the steering wheel turns smoothly to the left and right locks.
• Check that the number of turns are the same from the straight-forward position to the left and right locks.
• Check that the steering wheel is in the neutral position when driving straight ahead.

INSPECTION AFTER ASSEMBLY
When the steering wheel does not turn smoothly, check as follows:
1. Check the steering column for the following:
• Damage to the column tube or bearings
• Wear around the seal edges
• Corrosion or pitting around the seal sliding area
Replace the steering column as an assembly, if necessary.
CAUTION:
• Do not exert any axial load or impact to the steering column.
• Replace the column if it is depleted of grease, worn, damaged, or if any scratches or coating
separation is present on the shaft seal area.
2. If the vehicle has been in a collision, or if noises are heard com-
ing from the steering column, check column length (L1) and (L2)
as shown. If out of specification, replace the steering column as
an assembly.
3. Check the tilt device for proper operation range.
