Power Steering Gear: Reassembly

  1. Install needle bearings with longer edge of outer race facing outwards. Make sure that top end aligns with housing end surface.
  2. Install lower bearing so it is positioned 0.93" (23.6 mm) away from housing inner end surface on Land Cruiser, or 0.76" (19.4 mm) on all other models.
  3. Install "O" ring and Teflon ring to power piston. Install large and small "O" rings to gear housing. Install power piston assembly to gear housing. Tighten bolts.
  4. To adjust worm shaft preload, loosen lock nut and install adjusting wrench to adjusting plug. Install torque wrench to worm shaft and tighten adjusting plug to obtain specified preload, see Worm Bearing Preload  Table.
  5. Hold adjusting plug and tighten lock nut. Wrap tape around spline area of sector shaft. Align sector shaft gear teeth with power piston teeth (centered) and insert sector shaft into gear housing.
  6. Do not turn sector shaft during installation, as damage to "O" ring could result. Install sector shaft cover, with seal, to sector shaft adjusting screw.
  7. Turn screw counterclockwise until cover will fit completely down on gear housing. Install bolts and tighten. To adjust total preload of steering gear, place steering gear in center position and attach torque wrench to worm shaft.
