4. Install bass stud nut, tighten to specifications
and install new cotter pins; see Specifications Section at
rear o f this Section. Lubricate tie rod ends.
N O T E: N ever back off nut to align the cotter pin,
always tighten nut to next slot that lines up with
hole in stud.
5. Adjust toe-in as described in Section 3A.
CAUTION: Before
adjusting sleeve clamp holts, be sure that the
following conditions have been met:
a. The sleeve clamps must be positioned between
the locating dimples at either end o f the sleeve.
b. T he clamps must be positioned within the
a ngular travel indicated in Figure 3B-106.
c. The relationship o f the clamp slot with the slit
in the sleeve should be m ain tain ed as shown in Figure
3B-106.
d. Rotate both inner and outer tie rod housing
rearw ard to the limit
tightening clamps. Tighten
Return tie rod assembly to the center of travel.
e. All procedures for alignment, adjustment and
assembly of tie rods applies to each side.
f. Check each assembly to be sure that a total
travel o f at least 35° can be obtained using a bubble
protractor and a pair o f vise grips (Fig. 3B-107).
Inspection
To ensure proper in sta llatio n , it is necessary to
p erfo rm the following inspection after any change of toe
setting or removal o f any ball stud:
1. Check the total rotation o f the tie rod assembly
using the following procedure:
a. Lubricate inner and outer tie rod ends.
b. Attach vise grip pliers to the outer tie rod
end.
c. Rotate outer tie rod end counterclockwise (up)
to m axim um position. Attach bevel protractor as shown
tightening the tie rod
o f ball joint travel before
clamps to specifications.
in Figure 3B-107. C enter protractor bubble indicator and
record reading.
d. Rotate tie rod
m axim um position. Center protractor bubble indicator
and record reading.
e. Com pare protractor
Speps c and d. Total rotation of tie rod assembly should
measure at least 35 °.
f. If rotation is less than 35
sleeve clamp and rotate both tie rod ends to their
maximum limit both ends must be rotated in the same
direction
g. Tighten tie rod clamp and again rotate both
ends to their m axim um limits, repeating Steps c and d.
This recheck of total rotation will result in a m inim um of
35 ! travel.
h. A fte r o b ta in in g
rotation (35 ° or greater), position the outer tie rod end
approximately midway in this travel.
II' rotating checks, outlined above, reveal a rough or
lumpy feel, the inner or outer tie rod end assembly may
have excessive wear and should be replaced.
If all of the above mentioned conditions are met,
proper tie rod installation is assured.
Relay Rod
