In-Vehicle Adjustment

Adjust total on center load to eliminate excessive lash between the sector and rack teeth as follows.

1. With the engine (6007) off, turn the steering wheel (3600) from full right stop to full left stop at least once.

2. Refer to Section 11-04 for proper steering wheel hub cover removal procedure.

3. Disconnect the steering gear sector shaft arm (3590) from the steering gear sector shaft (3575) using Pitman Arm Puller T64P-3590-F.

4. Attach a newton meter (pound-inch) torque wrench to the steering wheel hub nut and determine the torque required to rotate the power steering gear input shaft and control (3D517) back and forth across the center position (± 90 degrees).

5. Reset the meshload only if the measured torque for total on-center load is less than 1.5 Nm (13 lb-in). If reset is required, loosen the adjuster lock nut and turn the sector shaft adjuster screw until the measured total on-center load torque is 2.0 Nm (18 lb-in). Hold the sector shaft screw in place and tighten the lock nut to 48-61 Nm (35-45 lb-ft).

6. Recheck torque readings and replace the steering gear sector shaft arm. Tighten the pitman arm-to-sector shaft nut 230-310 Nm (170-228 lb-ft).

7. Verify no binding condition in steering throughout full stop-to-stop travel. Verify customer concern is resolved.

8. Replace steering wheel hub cover.
