Preload Adjustment
- Install preload piston spring and adjusting nut in housing. Place steering rack in center position. Tighten nut to 3.7-4.1 ft. lbs. (5.0-5.6 N.m) using Adapter (5296 ) and Torque Gauge (9177 ). Loosen adjusting nut 50-55 degrees.
- Using Adapter (5179 ) and Torque Gauge (9177 ), ensure turning torque of pinion shaft is 9-18 INCH lbs. (1.0-2.0 N.m). If torque exceeds specification in any position, stop rack in that position. Readjust rack in high position.
- If turning torque is still more than specification, install new steering gear. If turning torque is okay, use a punch to stake lock nut to valve housing.
