• Leave clearance (L) when installing clamp (3).

• 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
aligned with rear cover cap projection (A) and the marking position
of gear housing assembly (B).

• After installation, bleed air from the steering hydraulic system.
