Worm Bearing Preload
- If steering gear is on vehicle, remove horn ring or button and disconnect pitman arm from sector shaft using a suitable puller. Turn steering wheel gently 1/2 turn from either stop, then loosen sector shaft adjusting screw several turns to eliminate sector load.
CAUTION: DO NOT turn steering wheel hard against stops with pitman arm removed from gear as damage to ball return guides could result.
- 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 less than 5-8 INCH Lbs., loosen adjuster lock nut and turn worm thrust bearing adjuster to increase preload. Tighten adjuster lock nut and recheck preload.
