outer socket and inner socket if they are outside the standard.
BALL JOINT ROTATING TORQUE
Make sure that the reading is within the following specified rangeusing preload gauge (A) [SST: ST3127S000 (J-25765-A)]. Replace
outer socket if the reading is outside the specified value.
BALL JOINT AXIAL END PLAY
Apply an axial load of 490 N (50 kg, 110 lb) to ball stud. Using adial gauge, measure amount of stud movement, and then make
sure that the value is within the following specified range. Replace
outer socket (1) and inner socket (2) if the measured value is out-
side the standard.

After installation, bleed air from the steering hydraulic system. Refer to ST-30, "Inspection".
Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
Check the steering wheel play, neutral position steeri ng wheel, steering wheel turning force, and front wheel
turning angle. Refer to ST-32, "
Inspection".
Check the fluid level, fluid leakage, and air bleeding hydraulic system. Refer to ST-30, "
Inspection".
Perform final tightening of nuts and bolts on each part under unladen conditions with tires on level ground when removing steering gear assembly. Check wheel alignment. Refer to FSU-7, "
Inspection".
Adjust neutral position of steering angle sensor after checking wheel alignment. Refer to BRC-64, "
