castle nut, use a puller to remove the tie–rod end
from the knuckle arm.
7) Remove the front crossmember support plate,
jack-up plate and front stabilizer.
8) Remove the one pipe joint at the center of the
gearbox, and connect the vinyl hose to the pipe and
the joint. Discharge the fluid by turning the steering
wheel fully clockwise and counterclockwise. Dis-
charge the fluid similarly from other pipes.
