from the edge of the hose.
• When installing lower joint to steering gear assembly, follow the procedure listed below.
- Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn gear-sub assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
- Align rear cover cap projection (A) with the marking position of
gear housing assembly (B).
- Install slit part of lower joint (C) aligning with the rear cover cap
projection (A). Make sure that the slit part of lower joint (C) is
