Steering Gearbox Installation
2.
'1.Before installing the steering gearbox, slide the
rack all the way to the passenger's side (right
direction).
Pass the right side of the steering gearbox together
with the tie-rods through the wheelwell opening on
the passenger's side. Continue moving the steering
gearbox toward the passenger's side untilthe
driver's side tie-rod end and gearbox clears the
master cylinder and under-hood fuse Ielay box.
Lower the steering gearbox. and move it toward
the driver's side untilthe steering gearbox is ln
Dosition.
Be careful not to damage the hoses, lines
and wire harnesses.
3. Installthe pinion shaft grommet (A).
4. Insert the pinion shaft up through the bulkhead,
then slip the right side of the steering gearbox
housing (A) over the mounting stud (C) on the
gearbox mounting bracket.
