ervoir, and remove P/S fluid reservoir assembly (for left-
steering vehicle).
7) Remove steering lower shaft joint bolt (2).CAUTION:

CAUTION:
Never turn gear box input shaft. Otherwise, air goes into
gear box, which needs air bleeding for gear box.
NOTE:
Don’t disassemble P/S gear box.
For adjustment of worm shaft starting torque, refer to
item “Adjustment of Worm Shaft Starting Torque” in
Section 3B.
