Steering Gear - Manual: Overhaul: Reassembly

  1. Place gear housing in a vise with worm shaft bore horizontal and sector shaft cover opening facing upward. All bushings and worm shaft bearing races should be installed.
  2. Place upper ball bearing over worm shaft. Install worm shaft and ball nut assembly into housing and up through the upper ball bearing race. Install bearing and retainer in worm bearing adjuster.
  3. Install worm bearing adjuster in housing. Tighten worm bearing adjuster until a very slight amount of worm shaft end play exists. Install sector shaft adjuster screw and shim in slotted end of sector shaft.
  4. Using feeler gauge, check clearance between adjuster screw and sector shaft when holding adjuster screw upward. Clearance should not exceed .002" (.05 mm). If clearance exceeds specification, a different thickness shim should be installed.
  5. To lubricate gear, rotate worm shaft until ball nut is at end of travel, while forcing as much grease as possible into housing without losing it out sector shaft opening. Rotate worm shaft until ball nut is at other end, and apply more lubricant.
  6. Rotate worm shaft until ball nut is at center of its travel. Install sector shaft assembly so center tooth of sector teeth enters center tooth space in ball nut.
  7. Apply more lubricant in the housing. Install side cover gasket. Coat sector shaft adjuster screw with a non-hardening thread sealant. Install side cover over sector shaft by reaching through cover with a screwdriver.
  8. Turn adjuster screw until sector shaft cover almost contacts the gasket. Install cover retaining bolts finger tight only. Turn sector shaft adjuster screw until sector shaft cover is tight against gasket and then loosen 1/2 turn. Loosely install a new lock nut onto adjuster screw.
  9. Lubricate all seals with grease. Wrap sector shaft treads with single layer of tape. Install sector shaft seal in the housing. Remove tape. Install worm shaft seal. Ensure seals are fully seated.
  10. Tighten sector shaft cover bolts to specification. Adjust worm bearing preload and overcenter preload. See WORM BEARING PRELOAD  and OVERCENTER PRELOAD  under ADJUSTMENTS in this article.
