Worm Bearing Preload

  1. If steering gear is on vehicle, remove horn ring or button and disconnect pitman arm from sector shaft using a suitable puller.
    CAUTION: DO NOT turn steering wheel hard against stops with pitman arm removed from gear as damage to ball return guides may result.

    Turn steering wheel 1/2 turn from either stop, then loosen sector shaft adjusting screw several turns to eliminate sector load.

  2. Use a torque wrench having a 50 INCH lb. maximum scale or less to measure preload. Attach torque wrench to steering wheel nut and turn through a 90° arc observing torque reading. If torque is less than specified in table, loosen adjuster lock nut and turn worm thrust bearing adjuster to increase preload. Tighten adjuster lock nut and recheck preload.
