housing be sure scribe marks are lined up. Also
use care not to cut rubber boot when installing wire

REPLACE STEERING LINKAGE
Steering connecting rod may be removed from
both tie rods, pitman arm and idler arm by removing
the ball shaft nut (Fig. 9-35 and 9-36). Since con­
necting rod is a solid shaft, it may be replaced by
installing a new rod and connecting It to pitman arm,
tie rods, and idler arm.
After steering connecting rod is removed the pit­
man arm may be removed from pitman shaft by
removing nut and lock washer and by using puller
J 5504-01. To install pitman arm on pitman shaft,
replace arm, lock washer and nut and tighten to 140
lb. ft. torque.
After steering connecting rod is removed, idler
arm may be removed by removing two bolts which
retain idler support to frame
0
Install assembly on
frame with two attaching bolts and washers and
tighten to 40 lb. ft. torque.
Tie rod assembly may be removed from car by
removing cotter pin and castellated nut on tie rod
ends at steering arms. To separate tie rod and tie
rod end, loosen two bolts on sleeve and clamp
assembly, and thread out part to be replaced. To
reassemble, thread new part into tube and clamp
assembly to approximate original location, place tie
rod end with dust cover in steering arm, tighten
castellated nut securely, and install new cotter pin.
When new tie rods or tie rod ends are installed
it is necessary to check toe-in. Check clamp bolts
on tie rod adjuster sleeve assembly for tightness
(17 ft. lb. torque) and bolts are to rear. Assemble
tie rod clamps as shown in Fig. 9-35 for Tempest
and Pontiac, Fig. 9-36 for Firebird models.
Whenever work is done on steering linkage it
should be lubricated.
NOTE: When installing complete linkage assem­
bly, tighten pitman arm to shaft nut before tighten­
ing idler arm to frame.
