N MANUAL STEERING STEERING WHEEL AND COLUMN Obtain the code number and deactivate the audio anti- theft system before disconnecting the battery. (Refer to section T.) On-vehicle Inspection Steering wheel play If the play exceeds specification, either the steering joints are worn or the backlash of the steering gear is excessive. With the wheels in the straight-ahead position, gently turn the steering wheel to the left and right and verify that the play is within specification. Play: 0--30mm (0-1.18 in) Looseness or play of steering wheel Move the steering wheel in directions a, 0, and @ to check for column bearing wear, steering shaft joint play, steering wheel looseness, and column looseness. Steering wheel effort 1. On level ground, jack up the front of the vehicle and sup- port it on safety stands. 2. Turn the steering wheel fully to the left and right at least 5 times. 3. Move the steering wheel to put the wheels in the straight ahead position. 4. Attach a pull scale to the outermost point of the steering wheel spoke. Then, starting with the wheels in the straight-ahead posi- tion, measure the effort required to turn the steering wheel to the left and to the right. Steering wheel effort: 5.0--29 N (0.S3.0 kgf, 1 .l--6.6 Ibf) (during one turn of steering wheel) 5. If not within specification, check the following: rotation starting torque of pinion, rotation torque of each ball joint, and steering joints. Gartner Banana
