HOLE COVER SEAL, HOLE COVER AND LOWER SHAFT ASSEMBLY
Check each part of hole cover seal, hole cover and steering column and lower shaft assembly for damage or
other malfunctions. Replace if necessary.
STEERING COLUMN ASSEMBLY
• Check each part of steering column assembly for dam age or other malfunctions. Replace entire steering col-
umn assembly if any parts are damaged.
• Measure the length (L) as shown if vehicle has been involved in a
minor collision. Replace steering column assembly if outside the
specifications.
• Measure steering column rotating torque using Tool. Replace steering column assembly if outside the stan- dard.
• Check tilt and telescopic mechanism operating range (L

RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal be fore starting the following procedure.
1. Connect the Tool between oil pump discharge connector and high-pressure hose. Bleed air from the hydraulic circuit while
opening valve fully. Refer to ST-30, "Air Bleeding Hydraulic Sys-
tem".
2. Start engine. Run engine until power steering fluid temperature reaches 50 ° - 80 °C (122 ° - 176 °F).
CAUTION:
• Leave the valve of the hydraulic pressure gauge fully open while starting and ru nning engine. If engine is
started with the valve closed, th e hydraulic pressure in oil
pump goes up to the relief pressure along with unusual
increase of fluid temperature.
• Be sure to keep hose clear of belts and other parts when engine is started.
3. Fully close the Tool valve with engine at idle and measure the relief oil pressure.
CAUTION:
Do not keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Replace oil pump if the relief oil pressure is outside the standard.
5. After inspection, disconnect the Tool from hydraul ic circuit, then add fluid and bleed air. Refer to ST-30,
"Air Bleeding Hydraulic System".
Tool numbers : KV48103500 (J-26357)
: KV48102500 (J-33914)

BOOT
Check boot for cracks. Replace if any damage is found.
OUTER SOCKET AND INNER SOCKET
• Ball joint swinging torque
- Hook a spring balance to the ball stud and inner socket measuring point (*) and pull the spring balance. Make sure that the spring bal-
ance reads the specified value when ball stud and inner socket
start to move. Replace outer socket and inner socket if they are
outside the specification.
• Ball joint rotating torque
- Make sure that the reading is within the following specified range
using Tool. Replace outer socket if the reading is outside the spec-
ification.
• Ball joint axial end play
- Apply an axial load of 490 N (50 kg, 111 lb.) to ball stud. Measuring
the amount of stud movement using a dial gauge, make sure that
the value is within specificati on. Replace outer socket and inner
socket if the measured value is outside specification. Tool number : — (J-44372)
