• Hook a spring balance at the point shown in the figure and pull the
spring balance. Make sure that the spring balance reads the spec-
ified value when ball stud and inner socket start to move. Replace
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 range
using 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 a
dial 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.
INSPECTION AFTER INSTALLATION
• After installation, bleed air from the steering hydraulic system. Refer to
• 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 steering wheel, steering wheel turning force, and front wheel
turning angle. Refer to
• Check the fluid level, fluid leakage, and air bleeding hydraulic system. Refer to
.
• 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
• Adjust neutral position of steering angle sensor after checking wheel alignment. Refer to
