  1. Tag and disconnect the power steering lines if equipped. Remove the steering housing brackets and remove the housing.
  3. Installation is the reverse of removal. Tighten the rack housing mounting bolts to 29-39 ft. lbs. (39-52 Nm), and the tie rod set nuts to 37-50 ft. lbs. (50-67 Nm). Use a new cotter pin. On Supras, install the intermediate shaft column side first, then rack side. On power steering equipped cars, bleed the power steering system and check for fluid leaks. Adjust toe-in on all models.
