Always replace both upper arm
bushings if either bushing is worn
or damaged. Install only new bush-

shaft.
1. Unscrew the bushings from the
inner shaft and suspension arm, then
remove the shaft from the arm.
2. Position the shaft in the arm.
Lubriplate and install the new bush-
ings on the shaft and the arm. Turn
the bushings so that the shaft is
exactly centered in the arm. The
shaft will be properly centered when
located at the dimension shown
in Fig. 7. Position the bushings
carefully to avoid damaging the
O-rings inside the bushings.

DISASSEMBLY
1 . Rotate the steering shaft approx-
imately 2% turns from either stop.
2. After removing the sector ad-
justing screw locknut and the hous-
ing cover bolts, remove the sector
shaft with the cover. Remove the
cover from the shaft by turning the
screw clockwise. Keep the shim
with the screw.
3. Loosen the worm bearing ad-
juster nut, and remove the adjuster
assembly and the steering shaft up-
per bearing and cup.
4. Carefully pull the steering shaft
and ball nut from the housing. To
avoid possible damage to the ball
return guides, keep the ball nut
from running down to either end
of the worm.
Disassemble the ball nut only
if there is indication of binding
or tightness.
5. Remove the lower bearing and
cup from the housing. It may be nec-
essary to tap the housing on a block
of wood (Fig. 8) to loosen it from
the housing.
6. Remove the ball return guide
clamp and the ball return guides
from the ball nut. Keep the ball nut
clampside up until ready to re-
move the balls.
7.
Turn the ball nut over, and
rotate the worm shaft from side to
side until all 62 balls have dropped
out of the nut into a clean pan. With
the balls removed, the ball nut will
slide off the worm.
Press both sector shaft bearings
out of the housing (Fig. 9). Remove
the seal and the bearings only if
there is a n indication of wear or
damage, or bearing mislocation.
Do not install a new bearing in a
housing in which the bearing has
turned or found to be mislocated.
A new housing must be used.
