Steering Outer Socket and Steering Inner Socket
SWING TORQUE
• Measure the swing torque, using Tool. When ball stud and steering inner socket start moving the measured
value must be within the specification. If the reading is outside the specification, replace the socket. Refer to
ST-31, "Steering Outer Socket and Steering Inner Socket"
ROTATING TORQUE
• Measure the rotating torque, using Tool. If the value is outside the
specification, replace the steering outer sockets.
AXIAL END PLAY
• Apply a load of 490 N (50 kg-f, 110 lb-f) to the ball stud axially. Use
a dial gauge to measure the amount of the movement that the stud
makes. If the value is outside the specification, replace the sock-
ets.
ASSEMBLY
1. Install the steering inner sockets.
2. Install the large-diameter side of the boots to the power steering
gear housing assembly.
3. Install the small-diameter side of the boots to the groove of the
steering inner sockets.
