• Measure steering column rotating torque using Tool (A). Replace steering column if the rotating torque is outside specification
• Measure the steering column length (L) as shown, if vehicle has been involved in a minor collision. Replace steering column if out-
side specification.
INSPECTION AFTER INSTALLATION
• Rotate steering wheel to make sure it is centered and there is no binding, noise or excessive steering effort.
• Make sure that the number of turns are the same from the straight-ahead position to the left and right locks.
• Check each part of steering column for damage or other malfunctions. Replace if there are any abnormal
conditions. Refer to ST-10, "
Inspection".
• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel turning angle. Refer to ST-5, "
Inspection".
• Check tilt mechanism operating range (T) as shown. Tool number (A)
: ST3127S000 (J-25765-A)
